Soybean cyst nematode resistant soybeans help with control–but only with rotation

In Delta Farm Press

New University of Missouri Extension plant pathologist Kaitlyn Bissonnette brings research on soybean cyst nematode (SCN) management to Missouri.

SCN numbers are growing in Missouri as farmers devote more acres to soybean production. SCN infests about 75 percent of Missouri fields, according to a recent survey by MU College of Agriculture, Food and Natural Resources researcher Melissa Mitchum. Many of these fields have high SCN egg counts. Continue reading

EPA Extends Comment Period for Neonicotinoid Risk Assessments

At the request of stakeholders, the U.S. Environmental Protection Agency (EPA) is extending the public comment period for recently released neonicotinoid insecticide risk assessments from February 20, 2018, to April 21, 2018. The Agency published preliminary ecological and human health risk assessments in December 2017 for the neonicotinoid insecticides, clothianidin, thiamethoxam, and dinotefuran, and a preliminary ecological risk assessment for imidacloprid (assessing risks to birds, mammals, non-target insects, and plants). In December 2017, the Agency also published new cotton and citrus benefits assessments for foliar applications of the neonicotinoids, as well as a response to public comments on the 2014 Benefits of Neonicotinoid Seed Treatment to Soybean Production Continue reading

Thrips resistance in cotton

In Southeast Farm Press

by Ron Smith, Alabama Cooperative Extension System

The first major insect we focus on during the cotton production season is thrips. Many have heard and read in recent years about the resistance of thrips to our available seed treatments.

We already recommend foliar sprays at the one to two true-leaf stage when cotton seedlings are not growing rapidly and/or thrips pressure is extremely heavy. As the resistance problem grows, we likely will see an increased need for foliar sprays on top of the seed treatments. Continue reading

EPA Finds Neonicotinoid Seed Treatments of Little or No Benefit to U.S. Soybean Production

On October 16, the U.S. Environmental Protection Agency (EPA) released an analysis of the benefits of neonicotinoid seed treatments for insect control in soybeans.  A Federal Register notice inviting the public to comment on the analysis will publish in the near future.

Loss of seed treatments could increase use of insecticides

From Delta Farm Press

Environmental groups appear to be setting their sights on the neonicotinoid class of insecticides and other pesticide compounds as the main culprits in honey bee population declines.

The evidence the insecticides are the main cause is sketchy, and the loss of those would put many farmers in an unprofitable situation, according to Jeff Gore, research entomologist at Mississippi State University’s Delta Research and Extension Center.

Controlling corn insects in 2013

Most corn insect control decisions are made before the planter hits the field. “Of course, decisions to control stalk borers in non-Bt corn, as well as cutworms and stink bugs in all corn, are made in-season,” says Auburn University entomologist Kathy Flanders.
