Are herbicides responsible for the decline in Monarch butterflies?

Monarch butterfly caterpillar feeds on a milkweed plant

The monarch butterfly is in bad shape. The number of monarchs returning to their overwintering sites in Mexico has been declining steadily for at least a decade. The consensus suggests there are several reasons for this decline, including loss of their overwintering habitat and unfavorable weather patterns. But the purported cause of monarch decline that […]

Using ethofumesate when irrigating for emergence

Bedding operation with "small" soil movement.

by Andrew Kniss & Abdel Mesbah At a recent meeting in Powell, I was asked how to best use ethofumesate (active ingredient in Nortron SC and other herbicides) in fields that must be furrow irrigated for sugarbeet emergence. This is a difficult question. Ethofumesate (and almost all soil applied herbicides) require soil moisture to be […]

If you’re a frog in a field, there are many ways to croak


Just saw a link to a story on the Guardian titled “Common pesticides ‘can kill frogs within an hour’“. Obviously, my interest was peaked. Global amphibian decline is a well-noted phenomenon, and it is possible that pesticides may play some role. But killing frogs “within an hour” is a pretty shocking result for a pesticide […]

Herbicides for sainfoin


We continue to get quite a few questions about weed control in sainfoin. Unfortunately, there are very few herbicide options currently registered for use in sainfoin (only 6 different active ingredients). We are investigating some additional herbicides in ongoing research trials. Although several herbicides look promising in our trials, these potential options will not be […]

Do genetically engineered crops really increase herbicide use?


Another interesting article about GMOs has been making the rounds today. This one was written by Dr.¬†Charles Benbrook, Chief Science Consultant for The Organic Center. This publication is an updated version of a report that The Organic Center published in 2009. The new version has been published in “Environmental Sciences Europe” and can be downloaded […]

Why I think the Seralini GM feeding trial is bogus

UPDATE: If you’re looking for information on the ‘republished’ version of this manuscript, a full statistical analysis of the released data can be found here. If you’re following the news about the French GM maize feeding trial, you’ve probably heard: (A) we need to pull GMO crops off the market immediately; or (B) that the […]
