Last week's cool wet weather delayed plant growth in corn and soybeans and rang the dinner bell for a variety of insect pests who made a feast of the vulnerable seedlings. While often corn might quickly outgrow the threat of significant pest damage, when plant growth stalled, armyworms, cutworms, wireworms, and white grubs found opportunity. Most of the reported problems seemed to be in east central and southeast Nebraska. Other factors such as soil crusting and planting problems also contributed to poor stands.
These developments reinforce the need for ongoing field scouting for insects in all crops. (See the June 8 Crop Watch for treatment thresholds for several corn pests.) "This is one of the worst years I've seen for insect damage," said Keith Glewen, NU Extension educator. "Whole hillsides of corn just disappeared." This week some farmers chose to fill in these holes in their fields by replanting corn. Based on research at Iowa State University, corn replanted June 10 would have a 67% yield potential compared to that planted between April 20 and May 5.
While the window for replanting corn is just about closed, producers pursuing this option should use a medium maturity hybrid and carefully consider potential yield, costs and the likelihood of an early fall frost. (Early frost probabilities are examined in an NU Cooperative Extension NebGuide, Autumn Freeze Probabilities.)
Research has shown that as planting dates are delayed, hybrids will start compensating. For every day from late May through early June, a given hybrid requires 5 GDD less to mature. So if planting was delayed from May 1 to June 10, delaying maturity by 40 days, a hybrid may require 200 less GDD, said Roger Elmore, Extension Crops Specialist at the South Central REC. In this case a 113-day hybrid may develop more like a 105-day hybrid.
Poor soybean stands caused by soil crusting and poor seed quality were an issue with other producers throughout the state. The window for replanting soybean also is narrowing. Beans sat in cool, wet soils for weeks and hadn't developed much. In fields where soybean plant growth was delayed, interseeding was a wise option this year, Glewen said. New seedlings may not be far behind earlier planted seedlings once temperatures warm up and stabilize. In a more typical year, interseeding may be problematic because plants within a field and even within a row will develop at different rates, complicating weed control and harvest.
For those producers choosing to replant poor soybean stands at this time, Elmore recommended choosing an early to mid season adapted soybean variety. "Consider planting a 10-20% thicker stand or plant in narrow rows to speed canopy closure," he said.
Bob Nielsen, Extension agronomist at Purdue University, recommends considering the following factors before replanting:
As evidenced by the range of problems this year, NU agronomists noted that replanting decisions should be based on conditions in a particular field at that time. Also, contact your crop insurance agent before deciding about replanting if you had replanting coverage.

After a relatively slow start, insect activity is picking up fast out west. Over the last couple weeks we have seen a long list of insect problems in various crops that have begun to concern us. In sugarbeets, variegated and clover cutworms have caused significant defoliation along with alfalfa loopers and beet armyworms. It's unusual to see these insects in these numbers this early in the year.
To evaluate the need for control, growers should consider the amount of defoliation that has occurred, the number of insects present, and the size of the larvae or potential for further damage. Because of the value of sugarbeets, thresholds for defoliation are lower than for other crops like corn. It is probably important to keep defoliation below about 20% of the leaf area. If beets begin to show 10-15% defoliation and insects are large enough to cause considerable additional defoliation, treatment should be considered.
We have seen a considerable delay in activity of sugarbeet root maggot flies. Peak fly activity is at least two weeks behind normal due to the cool spring. Insect development, like plant growth, is driven by the accumulation of temperature. The cool spring has delayed emergence and adult activity; however, in the last few days, we have seen increased female activity in the fields. This indicates that emergence is progressing and peak egg laying will not be far off.
Western corn rootworm first instar larvae were first observed this week in the Panhandle. This may be about a week later than normal, also likely due to the delayed season.
We have received several reports of Say's stink bug in wheat. This insect can be a problem in small grains, particularly during milk stage. One stink bug in ten spikes is considered significant enough to impact yield and quality. Infestations before or after milk stage are much less damaging.
The larvae of the painted lady butterfly -- the thistle caterpillar -- have been drawing a large amount of attention from anyone who has observed Canada thistle patches this spring. This migratory insect moves up from Mexico in the spring and is now present in very high numbers. Its presence could be a concern to sunflower growers. These insects will feed extensively on sunflowers, which should be carefully monitored for this insect. They will be found defoliating the leaves of sunflowers and the larvae will be found in a silken tunnel made from the edges of rolled up leaves.

Karnal bunt, a wheat disease caused by the fungus Tilletia, was recently found in Throckmorton and Young counties in Texas. This doesn't pose a serious threat to Nebraska, but growers using custom combiners should take precautions.
Since bunt spores can be moved on equipment, Nebraska growers using custom combiners should be careful about the equipment they let into their fields. Inquire as to where your custom combiner has been. If they have been in the areas in Texas where karnal bunt was detected, ask if their equipment has been properly cleaned and if the operators have a USDA certificate to prove it. Also, take the same precautions if you use portable seed cleaners.
Each year the Nebraska Department of Agriculture surveys wheat for karnal bunt. Steve Johnson of the NDA said 40 samples will be pulled from wheat being brought into elevators in 20 Nebraska counties. The samples will then be submitted to the Kansas Department of Agriculture, the regional lab conducting karnal bunt testing. The Nebraska survey is part of a national USDA survey, he said, conducted to:

"These findings do not provide any evidence that the reactions that the affected people experienced were associated with hypersensitivity to the Cry9c protein. The difficulties of this investigation highlight the importance of evaluating the allergic potential of genetically modified foods before they become available for human consumption."

The cool, wet weather which developed during early soybean establishment has reduced growth, vigor and stands in some areas. Taken together these factors give weeds a competitive edge over the crop. Consider the following points:
2. Reduced soybean stands give weeds more opportunity to emerge and grow so the critical period for weed control is extended. While later emerging weeds are less competitive, they can cause harvesting problems and can produce abundant seeds.Extended weed control may be needed in soybeans this year
1. Early weed control is important to give soybeans an opportunity to get ahead of the weeds. If a preemergence herbicide was not used, an early postemergence application will be needed. See the June 8 Crop Watch article on postemergence weed control in soybean for herbicide choices.
Since the majority of soybeans are Roundup Ready varieties, let's review the Roundup Ultra Max label for maximum allowable application rates and timing considerations:
1. Combined total per year for all applications is 6.5 quarts per acre.
Roundup Ultra Max is a 5.0 lb ai/gallon formulation of glyphosate (3.75 lb ae/gallon). Other glyphosate brands may have similar rate maximums (based on acid equivalents), but be sure to check labels for specific information. (See "The many faces of glyphosate" in the May 18 CropWatch.) Apply glyphosate with 1% to 2% ammonium sulfate. Mix the ammonium sulfate with water in the spray tank before adding glyphosate. Some glyphosate brands require a surfactant.
2. Total for preplant and preemergence applications is 4.0 quarts per acre.
3. Total in-crop applications from emergence through flowering is 2.4 quarts per acre.
4. Maximum rate for any single in-crop application is 1.6 quarts per acre.
5. Maximum total during flowering is 1.6 quarts per acre.
6. Maximum preharvest application rate is 0.8 quart per acre.
7. Allow at least 14 days between final application and soybean harvest.

European corn borer (ECB) moth flight has been light this year. Light traps at Clay Center began to capture moths on May 15 and at Concord on June 6. Current information on black light trap catches can be found at the UNL Department of Entomology web site.
Even in years when European corn borer numbers are low, some fields, particularly popcorn or seed corn fields, can have economically damaging populations of borers. Popcorn fields often attract more egg-laying European corn borer moths than surrounding field corn does, and the high value of seed corn means that their European corn borer economic thresholds are low.
Timely and accurate scouting is the key to managing European corn borer in standard (non-Bt) corn hybrids. Remember that conditions are localized and fields must be scouted individually to make accurate decisions.
Information on first generation European corn borer management is available in First Generation European Corn Borer Scouting and Treatment Decisions, NebFact 98-364. This publication is also available at your local cooperative Extension office.
It includes a worksheet (seen to your right) that allows you to calculate if treatment is justified for first generation ECB in field corn. This worksheet also can be used for European corn borer in popcorn. If using the table for popcorn, yield terms (e.g. yield loss) can be expressed in pounds per acre and crop value in dollars per pound.
Many insecticides are registered for control of first generation European corn borers and most will do a good job if applied properly at the right time. The Bt-based insecticides Dipel, Condor, M-Peril and others are effective and do not reduce populations of corn borer natural enemies.
Refer to the Insecticides for First-Generation European Corn Borer Control in Field Corn web page for a list of suggested insecticides.
If you are growing Bt corn this year, remember to manage your refuge fields or acres the same as the Bt cornfield they are associated with. In this way you will have Bt susceptible moths present to mate with any possible Bt resistant moths that may come from your Bt cornfields. Matings between Bt susceptible and resistant moths will help dilute the pool of resistant genes in the European corn borer population and preserve Bt corn as an effective management tool for the future.
The exception to this is if European corn borer populations in your refuge corn reach economically damaging levels. You are then allowed to treat your refuge with non-Bt insecticides.
Finally, if you don't have problems with first generation European corn borer, you should still be prepared to scout for second generation borers later this season. If the conditions are good for larval survival, it won't take many first generation moths to produce economically damaging populations of second generation borers. Additional information on European corn borer management is available at the Entomology web site.

Yellowish alfalfa has been showing up at Extension offices across Nebraska. As we discussed growing conditions and cultural practices, these fields had several factors in common.
First, the alfalfa was planted last year. If it was a spring planting, it usually did not grow especially vigorously.
In most cases, alfalfa had not been present in the field for many years. And just about as often, no soil test was taken.
Usually, the yellowing is variable across the field. Sometimes it's associated with topography, but not always.
So what is the problem? Well, if the alfalfa is yellow only in low areas, the problem can be phytophthora root rot. But what I see more often is a nitrogen deficiency.
This may seem odd since alfalfa can make its own nitrogen -- given the right conditions.
In these cases, the alfalfa is not forming nodules to make nitrogen because the soil is acid or the seed wasn't inoculated. Alfalfa needs a soil pH above 6.2 and adequate inoculum to form nodules. Our surface soils are becoming more and more acid because both tillage and nitrogen fertilizer increase soil acidity. Lime is needed to neutralize soil acidity. And even if soil pH is acceptable, the correct type of Rhizobium bacteria also are needed.
Fields that have not grown alfalfa in the past two or three years often need more bacteria added with the seed.
Soil testing, lime, and inoculants pay when needed.

Disease is a natural part of every crop production system. This is true for every crop species and for each type of production system: irrigated versus rain-fed, conventional versus reduced tillage, and continuous versus rotational cropping. In any given year, the question is not whether diseases will occur in Nebraska's field crops, but which diseases will occur and at what incidence and severity.
Many factors influence disease development in plants including hybrid/variety genetics, age of the plant at the time of infection, environment (e.g., soil, climate), weather (e.g., temperature, rain, wind, hail, etc.), single versus mixed infections, and genetics of the pathogen populations. Due to variation inherent in these factors, diagnosis of plant diseases can be difficult at the early disease stages; however, many diseases begin to cause more easily recognizable symptoms as the disease develops, providing a reasonable level of confidence in diagnosis.
To help producers, consultants, and other agricultural professionals in the diagnosis and management of field crop diseases in Nebraska, the Plant Disease Central (PDC) web site was developed by faculty in the UNL Department of Plant Pathology.
The site offers a variety of features, including a "hot topics" section, county and scouting reports, a disease forecast, glossary of terms, and perhaps most importantly, it provides an online, detailed reference to specific field crop diseases of Nebraska, including photos and treatment recommendations. While information is not yet available on the site for all diseases, many are represented. Detailed information describes the disease, its pathogen and development cycle, symptoms, and favorable weather conditions contributing to its development. NU's Plant Disease Central also links to NebGuides, NebFacts, other Cooperative Extension sites and publications from other universities or relevant government sites.
The site is still under development so comments on the usefulness of the information and images for specific diseases as well as for the site itself are encouraged and would be appreciated. Email links are provided on the site for providing feedback.
Following is a description of many of the site's features:

A new book from the University of Nebraska Cooperative Extension is designed to provide indepth information targeted to Nebraska's crops, soils and major nutrient management issues. The 176-page "Nutrient Management for Agronomic Crops in Nebraska" provides nutrient recommendations for all of Nebraska's major agronomic crops in a single resource.
The manual contains two components - a section outlining nutrient management principles and key information on macro and micro nutrients and a section containing fertilizer needs, strategies and recommendations for specific crops.
The Extension resource was written by soil fertility faculty in the University of Nebraska Department of Agronomy and Horticulture and is a valuable resource for producers, crop consultants, fertilizer dealers and others involved with crop production in Nebraska. With color photographs, illustrations and 90 tables, information is well-organized, indexed and easily accessible as a learning tool for indepth study or a companion reference for field application.
Two of the chapters are available for viewing on the Web on the Crop Watch Focus Nitrogen web page.
The list of book chapters shows the range of information. The price of the manual is $25. Copies of EC01-155, Nutrient Management for Agronomic Crops in Nebraska, may be ordered through your local Cooperative Extension office or from the Institute of Agriculture and Natural Resources at:

Rust diseases are the most important wheat diseases worldwide. Stem rust, potentially the most serious of the three rusts, is effectively controlled through resistance. However, resistance to leaf rust, a serious disease in eastern and central Nebraska, is less common than it is for stem rust. Breeding programs must continually evaluate their material for reaction to the rust diseases so that protection through resistance is maintained in released varieties.
This increase in rust virulence corresponds with a significant increase in acreage of the variety Jagger grown in Kansas and southern Nebraska. Jagger contains gene Lr17. This same trend occurred with the varieties Siouxland and Karl 92, both of which lost their leaf rust resistance within five years of their release. Knowing how often new rust races appear is an important part of breeding for rust resistance. This can only be accomplished through the annual monitoring of the Nebraska leaf rust population and by screening lines early in their development for resistance or susceptibility to the ever changing rust race population.
We have monitored the Nebraska leaf rust population since 1993 and have noted significant changes in the rust races and in the virulence frequency to individual leaf rust resistance genes. For example, the 2000 leaf rust field collection from Nebraska separated into 43 distinct races which illustrates the tremendous diversity of this pathogen. Some of these races were capable of attacking at least 10 different leaf rust resistant genes.
The Nebraska wheat breeding program bases its leaf rust resistance on host gene Lr16. So far none of the leaf rust races collected in Nebraska have shown virulence to this gene; however, virulence to this gene has been increasing in other wheat growing areas of North America. If the resistance provided by Lr16 begins to break down because of race shifts in the pathogen, our monitoring program will detect this change. The wheat breeding program in turn can use this information to use other leaf rust resistant genes in its breeding program. Through this process the release of highly rust susceptible varieties will be avoided, making Nebraska growers less prone to losses from this serious disease.

Many wheat growers are worried about poor grain yields due to thin stands, dry soils, uneven maturity, and various pests. With prices well below $3 a bushel, gross income looks discouraging.
In a year like this, wheat hay may be a viable alternative. Since wheat usually yields more than two tons of hay per acre, you might make as much or more money harvesting for hay as for grain. Plus, crops like sudangrass or millet or soybeans could be double-cropped into the stubble if insects and moisture aren't a problem.
If you decide to harvest wheat hay, consider forage quality as well as yield. If you plan to feed wheat hay to young stock or lactating cows, late cutting will not provide the quality you'll need. Protein and TDN will be too low. To provide for good yield with a relatively high protein and energy, cut your wheat as soon as possible after heading. Protein should be 8% -10% and TDN will be about 60%. This younger forage should be very palatable.
To winter beef cows, though, harvest can be delayed until milk to soft dough stage. Yield will be slightly higher, but protein will have dropped to 6% to 9% and TDN will be 50%-60%. Hay could be quite coarse, though, so intake will be less than with an earlier cutting. Grinding might be useful.

Pesticide applicators can turn in their used containers at one of 62 collection sites statewide. In 2000, the program's ninth year, the program collected nearly 71 tons of recyclable plastic containers.
"Based upon last year's totals and this year's record number of recycling sites, we are expecting to receive an even larger quantity of containers," said University of Nebraska Cooperative Extension pesticide coordinator Larry Schulze, who developed the program and administers it, with the help of extension educators through NU's Institute of Agriculture and Natural Resources.
As in past years, the program will accept pressure or triple-rinsed 1- and 2.5-gallon plastic pesticide containers. They need to be dry and clean, inside and out. Caps, labels and slip-cover plastic labels must be removed since they cannot be recycled as part of the program.
Twenty-six of the 62 collection sites accept 15 and 30-gallon plastic crop protection chemical, crop oil and adjuvant drums in addition to the 1- and 2.5-gallon plastic pesticide containers.
Mini-bulk, saddle tanks and nurse tanks, which sometimes are made of fiberglass or different types of plastic not compatible with the recycling program, will not be accepted. The drums must be thoroughly rinsed before being delivered to collection sites and should not be cut or opened in any way.
Before delivering containers to a collection site:

Based on June 1 conditions, Nebraska's 2001 winter wheat crop is forecast at 61.2 million bushels, unchanged from last month but up 3% from last year's crop, according to the USDA's Nebraska Agricultural Statistics Service. Average yield is forecast at 36 bushels per acre, 1.4 bushels below the 10-year average.
Acreage to be harvested for grain is estimated at 1.7 million acres, up 3% from last year. This would be 94% of the planted acres. As of June 1, topsoil and subsoil moisture supplies were rated mostly adequate. The crop was about one week behind normal as fields began turning color. Disease and insect pressure to date was light.

Keith Jarvi, Extension Integrated Pest Management Program, Northeast REC: We are receiving many calls about alfalfa failing to green up after the first cutting. Tom Hunt, Extension entomologist, NEREC. and I looked at a field near Winside Tuesday morning and found it loaded with variegated cutworm. I believe these were already mentioned as a possible threat in previous newsletters.
The thresholds are similar to that of army cutworm: two or more per square foot on newly seeded alfalfa and four or more on established stands.
This field had a minimum of five per square foot and the cutworms were clearly holding back the regrowth. Much of the field was affected, but other fields could just have patches affected. Pounce, Warrior, Baythroid, and Lorsban at the lowest labeled rates should control these cutworms if moisture conditions are normal to moist. The cutworms will hide in the ground near the plants or under windrows during the day. The best time to scout and/or treat would be late day-evening or very early morning.
Jim Kalisch, Extension Entomology Technologist, reported Thursday that they were also receiving reports believed to be of variegated cutworms causing damage in south central Nebraska soybean seedlings.
Keith Glewen, Extension Educator in Saunders County: We have had above normal damage from early season insects in corn. Its not uncommon to see large areas on side slopes where insects have reduced the stands to less than 10% of the original population. The extended period of damage was probably brought on by the cool/wet growing conditions. The lack of uniformity in the corn crop is a problem that will haunt us the remainder of the growing season. In some cases insects, disease and weather conditions have also placed some soybean fields in the replanting category.
Tom Dorn, Extension Educator in Lancaster County: I have had a few reports of insect activity on corn, mostly cutworms of various types. I have seen yellow-striped armyworm and some common stalk borer in corn. I have found damage consistent with cutworms and flea beetles as well.
I was asked to look at a field of corn with an extremely poor stand, especially on the more highly eroded hilltop. The soil was quite wet, making it difficult to dig out the skips. Digging in the row, we found a few seeds that had sprouted but the shoot had either broken off or had been cut off about a half-inch below the soil surface. Brady Kappler, weed science educator, ruled out any direct herbicide injury. If this breakage were due to crusting problems, subsequent moisture had softened any crust that may have existed. If it were due to insect damage such as cutworms, they could no longer be found. This field will need to be rotated to grain sorghum and replanted using safened seed when soil moisture conditions permit field operations.
Terry Gompert, Extension Educator in Knox County: Pasture growth has slowed to 1/4 inch per day. The warm season grass is growing at 1/2 inch per day. Both rates are half of normal. The effects of last year's drought and cool weather and limited rain in May and June are beginning to show up. Range and pasture are projected to be short in 30 days.
Most of the hay is cut and ready to bale. Some cutworms and alfalfa weevils are slowing regrowth. First cutting yields have been heavy and above average, however quality is poorer than normal due to the delayed harvest. Some soybeans are in dry soil causing populations to be poor.

to provide resistance to new lines
The history of breeding for leaf rust resistance in winter wheats in the Great Plains has proven to be a never-ending battle. Whenever new resistant genes have been used alone over significant areas, the corresponding virulence to these genes has appeared and increased in the leaf rust pathogen (Puccinia triticina) population within a few years. For example, since 1995 the rust virulence to host gene Lr17 has increased nationwide from 2% in 1995 to 21% in 1998.
