After a warm start to planting in mid April and a big cool down for several weeks in late April, the crops are growing rapidly now. Stage of growth of corn and soybeans are about the same as 2009 in south central Nebraska. Some severe hail damage occurred 7 days ago in east central Nebraska.
Corn is mostly V5 to V7 stage, some of the first planted on soybean ground is V8. Post glyphosate treatments need to be finished soon on the bigger corn. The best weed management has still been an early preplant or pre emerge residual herbicide treatment, followed by a glyphosate treatment with a tank mix partner to control the few weed escapes and prevent glyphosate resistance development.
Recent rains will have farmers scrambling to get all the post products on properly. Hilling or ridging on the ridge-till fields will need to be done soon. Any extended period of rain allows the corn to rapidly outgrow the tillage operation.
Dingy cutworms have been unusually high this year. The eggs are fall laid by a moth. They emerge in the spring to slowly damage corn over a 3-4 week period. V7 corn can still have the large larvae kill the plant by eating out the growing point that is near the soil surface. The seed treatments and some root worm insecticides do not control them very well.
Early planted soybeans are in the 3-4 trifoliate stage. If a burndown residual herbicide was applied earlier, waterhemp and some nightshade escapes are becoming prevalent and will need to be control in the next 10 days before growing beyond the labeled height for glyphosate control alone. Again, using some tank mix partners may aid in control with glyphosate on the bigger weeds.
It is evident that many growers are still relying on glyphosate only for weed control. Very large 18-20 inch lambsquarter and horseweed/marestail are in some soybean fields that still haven't been controlled.
