Bt corn and ECB resistance management:

Planning refuge plantings for 2003

Mark your calendar!

This week and in the next CropWatch information on a variety of UNL educational and training opportunities for farmers and agribusiness will be featured.
Insect resistance management (IRM) has been an important topic since the advent of Bt transgenic corn. If you've grown Bt corn in the past, you're familiar with resistance management and the use of refuges. When buying Bt corn, seed farmers are required to sign contractual grower agreements that state they are aware of and will comply with resistance management requirements.

Requirements for 2003 are the same as last year, but since there were slight changes in 2002, it's a good idea to review the current requirements and plan accordingly when ordering seed. Resistance management for European corn borers and Bt corn revolves around the use of refuge plantings. In Nebraska, a refuge is non-Bt corn. The purpose of the refuge is to supply a source of Bt-susceptible corn borers that can mate with resistant corn borers potentially emerging from nearby Bt corn. Specific resistance management information will be a part of each corn seed bag label. Be sure and discuss resistance management with your seed dealer.

The 2003 EPA requirements for resistance management are:

Additional information concerning Bt corn, European corn borer, and resistance management is available in the Nebfact

Nov. 8 farm bill meeting

Using on-line software to compare your options

If you're like many producers, you may still be researching and examining your options under the new farm bill before making a six-year commitment.

A Nov. 8 NU Cooperative Extension satellite conference will provide training to help producers use one of several Web resources on the farmbill -- an on-line program developed by Texas A&M University. The satellite conference will be from 10 a.m. to noon next Friday. Check with your local Cooperative Extension office for potential downlink sites.

The meeting will cover how to use the on-line Base and Yield Update Option Analyzer, how to correctly input data, and how to interpret the results to make an informed decision. The program is available at http://www.afpc.tamu.edu/models/bya/

USDA farm bill resource

USDA's Farm Bill 2002 includes a variety of resources, links to resources and program updates which also may be helpful to decision-making. The site is at http://www.usda.gov/farmbill/
Presenters will include Dr. James Richardson, TAMU Public Policy Specialist and one of the software developers, Dr. Roy Frederick, NU Public Policy Specialist, Randy Pryor, NU extension educator in Saline County and program coordinator, and Doug Klein, programs specialist with Farm Services Agency. The meeting will include time for speakers to answer questions from participants at the downlink sites.

The 2002 Farm Bill provides farmers and landowners a one-time opportunity to update the contract base acres and farm program yields used to calculate program benefits. Deciding what to update is complex and may involve several commodities and uncertain market conditions, which drive future counter-cyclical payments. Selections made this year can have long-term implications -- the base and yield elections made before April 1, 2003, will apply for at least the next six years.

The primary benefit of the Texas A&M program is how it includes guaranteed direct payments and counter-cyclical payments that are not guaranteed. The computer analyzes each base option using 500 counter-cyclical prices. The results of simulating the six base and yield alternatives on a farm unit amounts to 21,000 estimates of government payments per crop. The price model helps a producer or landlord see which option ranks the highest out of 500 times.

Drought, heat, hail pummel yields in long-term tillage, rotation research plots

The hot, dry weather put many crops and cropping practices to the test this season. In many areas, differences in tillage systems, planting dates, or other management factors made large differences in productivity. Producers often wonder how different tillage systems will perform, both in a year like this one and over the long-term.

*Full plot harvest with a combine and weigh wagon; corrected for moisture.
** Severe hail one week before harvest threshed out about half the yield.

The 2002 yields for a long-term tillage system study on the University of Nebraska Rogers Memorial Farm (10 miles east of Lincoln) are given in the table. These research plots, established in 1981 in a dryland soybean/grain sorghum rotation, show that long-term no-till builds soil structure, usually has the highest yield, and is the most profitable.

There were adequate rains in May to fill the soil profile, replacing the soil moisture lost to preplant tillage. However, no rain fell from May 30 to July 6 and only 1.10 inches fell in July. About 6.75 inches fell from August 12 through August 23 and a thunderstorm with severe hail dumped about 3 inches of rain on August 28. Even with this much rain, there was virtually no runoff from the long-term no-till fields on the farm. The creek running through the farm was out of its banks, over the road next to the farm because of runoff from the surrounding areas.

The mid-August rains may not have added much to the yield of grain sorghum which was near maturity at the time. Unfortunately, the hail stripped the leaves and threshed out about one-half the yield, turning the ground red with grain. Even with the storm damage, the no-till without cultivation treatment had the highest yield and the fall plow treatment had the lowest, much like previous years. (See previous related stories in the CropWatch archive on the Web at http://cropwatch.unl.edu/archives.)

Similarly, the hail stripped most soybean leaves and damaged many pods, knocking some to the ground. The rainfall was welcomed for pod-fill but the damaged plants had little leaf area remaining for photosynthesis and growth. At harvest, many of the beans were discolored, diseased, or shriveled. While no-till did have the highest yield and plow the lowest, the hail made the comparison of tillage systems difficult. On other areas of the farm that didn't receive much hail, the same soybean variety planted no-till yielded 30 to 50 bushels per acre, depending on soil type.

Over the years, it has been observed that the long-term no-till treatments have better soil structure, more residue cover, and less surface crusting. These conditions are improving the water infiltration rate and decreasing runoff, making rainfall more effective with long-term no-till. With no tillage operations, better soil structure, and higher yields, no-till is the most profitable tillage system.

Management tips


Pesticide applicator regulations change for 2003 production season

Several changes were made in Nebraska's pesticide regulations in 2002 which will affect pesticide application and applicator licensing and certification for the 2003 crop production season. These changes are outlined below and will be addressed in initial certification and recertification training this winter.

Pesticide training opportunities

A number of meetings and exams have been scheduled for individuals interested in becoming certified or recertified as a pesticide applicator.

A person becomes certified by successfully completing the required exams or recertified by either completing a continuing education course or successfully completing the exam. Once certified, a person needs to become licensed. Persons completing certification will be sent a billing statement by the Nebraska Department of Agriculture for a license. A three-year commercial license costs $90. When the fee is paid, the State Department of Agriculture will issue the license. Persons completing certification as a noncommercial applicator will be sent a license without a fee.

To order materials, contact the:
Pesticide Education Office
University of Nebraska
101 Natural Resources Hall
Lincoln, NE 68583-0820
Phone: (800) 627-7216 or (402) 472-1632
Fax credit card orders to: (402) 472-3574

Initial commercial/noncommercial certification is based on satisfactory test scores on a general standards exam plus one or more category exams. Preregistration is required. However, registration will be at the door at Crop Protection Clinics for Ag Plant recertifications. Consult the program schedule to determine the appropriate location for the categories being sought. Study materials are optional for recertification but are required for all initial pesticide applicator programs. To order study materials, contact the UNL Pesticide Education Office at least 10 working days before the training date. A form and further information are available on the Web at http://pested.unl.edu/PAT2003ScheduleBrochure.pdf. Individuals also can use a credit card to order by phone or fax.

Field guide on Harlan County Dam and lake explores area's geology

A new University of Nebraska-Lincoln publication covers the geology and history of the flood-busting Harlan County Dam, which was completed 50 years ago. The "Field Guide to the Geology of the Harlan County Lake Area, Harlan County, Nebraska -- With a History of Events Leading to Construction of Harlan County Dam" is available from the university's Conservation and Survey Division.

Construction of the dam came after a massive wall of water from the Republican River, caused by torrential rains, devastated farms, buildings and homes and killed 94 people in southwestern Nebraska May 30-31, 1935. All or parts of many Nebraska towns near the river were flooded, and more than 57,000 acres of farmland damaged or destroyed. The value of property lost or damaged in Nebraska was estimated at up to $163 million in year 2000 dollars. After that catastrophic flood, the U.S. Army Corps of Engineers designed and built the Harlan County Dam and Lake on the Republican River.

The 61-page multi-author publication is of general and scientific interest. It includes sections on the area's geology, water resources and fossils, as well as structural features such as landslides, jointing, faulting and folding. The publication also details how the dam's construction changed the area's land and water resources.

The circular costs $16. Orders should be placed by order number (EC-16) with the Conservation and Survey Division, 113 Nebraska Hall, University of Nebraska-Lincoln, Lincoln, NE 68588-0517. Add $1.50 for mailing and handling. Nebraska residents should add city and state sales tax. Orders must be prepaid. Call (402) 472-7523 or e-mail csdsales@unl.edu for more information or details about credit card payments.
