Jennifer Rees, Extension Educator in Clay County:  Corn here is anywhere from V2-V7 and most beans are from cotyledon to V2 stage. Fertility strips are visible throughout fields; hopefully, they should come out of it with more sun and growth. A few herbicide issues have been observed that we normally wouldn’t see. There is some potential damping off of corn in areas and we're seeing some effects of cold temperatures on seed germination with a few hybrids. Leaf rust is starting in wheat. Alfalfa weevils were fairly thick in some first cutting alfalfa fields so producers need to be watching second cutting regrowth to determine if they need to spray. (See related CW article.) Corn is starting to be hilled and we could use a nice rain.

John Thomas, Extension Educator in Box Butte County:  Wheat varies from pre-flowering to almost flowering, and from good to pretty poor. SOme of the poor fields are poor stands and extremely weedy.  It has adequate moisture, but will need additional rain to mature the crop. Some good wheat around and some pretty poor wheat. Varying emergence. Dryland corn is in the 5-7 leaf stage with a lot of variability. Dry beans are 90% planted, and 15% emerged. About 50% have taken their first cutting of alfalfa. Potatoes are off to a good start, but were delayed due to cool conditions. Dry edible peas look excellent and benefitted from the cooler weather. The northern Panhandle has had a little better moisture than some areas in the southern Panhandle and crops have responded accordingly. Overall, moisture has still been patchy, but adequate for the time, but we'll need more for dryland crops to make it.

Jeff Bradshaw, Extension Entomologist at the Panhandle REC: During the past week we began detecting potato psyllids in the Nebraska Panhandle. Adult populations are low (from 0.2-0.4 psyllid per sticky trap). Many potato fields have not yet emerged; therefore, these adults are likely to begin establishing on solanaceous weeds (for example, ground cherry and nightshade). In recent years, psyllids have been more frequent and arriving earlier in Nebraska. Recent research in my lab has found evidence that these insects may survive the winter further north than previously thought. This more northerly survival may be contributing to these early populations. We'll keep CropWatch readers updated on this pest as the season develops. We're also seeing the first big emergence of miller moths this season. (For more information on miller moths see Bradshaw's May 3 CW article.)

Tyler Williams, Extension Educator in Holt County:  The pivots have started up again and the corn is really taking off. The wheat is polliinating and the few acres under a pivot look good. Dryland wheat will be very poor this year. Soybeans are almost all emerged and a lot of spraying is underway.

Gary Zoubek, Extension Educator in York County: We've been installing water sensors to aid in irrigation management. When the wind cooperates, producers have been applying herbicides. Much of the corn has been light yellow, but now is turning green and taking off as the roots reach nitrogen. The earliest planted corn is at the V5-V6 stage. At this time last year it was at the V10 stage.  Soybeans are at the V1-V2 stage, compared to V4 last year.
