Research over the last couple of years has shown that two shot burndown programs which include either 2 shots in the spring or fall plus spring burndown treatments are needed in areas with a history of poor marestail control due to glyphosate and ALS herbicide resistance.

Use your yield monitor to mark locations for more than just rocks and evaluate crop performance.

Field crop growers may already be aware that stink bugs could cause injury to soybeans, but it seems the smelly pests could also cause problems for both sweet and field corn, entomologists with Ohio State University's College of Food, Agricultural, and Environmental Sciences said.

Corn growers who find unexpected lodging during harvest could find that the problem is caused by Bt-resistant western corn rootworm, an entomologist with Ohio State University’s College of Food, Agricultural, and Environmental Sciences said.

We have published articles about fall herbicide treatments in C.O.R.N. over most of the last five years or more.

Every year Iowa State University (ISU) Extension and Outreach provides private pesticide applicator training covering a variety of pesticide safety and pest management issues. In response to reported incidences of Bt-resistant corn rootworm, a series of remote "clicker" questions were developed to survey current corn rootworm management practices and assess the degree to which farmers perceived resistance in 2012.

This year, due to poor spraying conditions, wet planting conditions and increased resistance, there are a lot of fields with weed escapes.

Several people have submitted images of escaped "pigweeds" wondering whether the plants were Palmer amaranth. In all cases, except the earlier reported situation in Harrison County, the plants in question have been waterhemp, although at casual glance they could easily be mistaken for Palmer amaranth.

Plants in many fields have heavy ears, along with shallow roots because of abundant rainfall, and many of these plants could topple easily as they mature, especially if a late-season storm with high winds blows across the field.

Palmer amaranth has been increasing around the Midwest and CREP seedings can apparently be one source of new infestations.
