Mixed Bag of Early Season Caterpillar Defoliators in Soybean

🕔07:23, 23.May 2015

Over the last couple of weeks I have had numerous calls about caterpillar pest in young soybeans. Most of these have been concerning beans that are still in the vegetative stages (V2-V5). The species that are being found are bollworm, yellowstriped armyworm, green cloverworm, granulated cutworm, alfalfa caterpillar, cabbage looper, garden webworm, and yellowstriped armyworm.

Do Neonicotinoid Seed Treatments Have Value Regionally in Soybeans?

🕔14:34, 31.Oct 2014

There has been a tremendous amount of scrutiny put on the neonicotinoid class of chemistry in recent years because of the potential link to declines in bee numbers. Researchers are working feverishly across the nation and the globe to determine the exact causes of bee decline. No doubt pesticides can and likely play a role to some degree, but there are many factors that also influence bee health such as habitat loss, Varroa mites, and diseases.
