Alfalfa weevil numbers continue to rise across NEK. See the progress in this week's blog post this week at: https://t.co/nvO2jhhSMW . It also includes posts on Roughleaf Dogwood and buckbrush.

Alfalfa weevil control is problematic in Kansas for several reasons, but probably first and foremost is the weather. Check out the article for an insect update on alfalfa weevils: https://t.co/DjoKX6Jy0q

Check out the article for an update on the EPA issuing a cancellation order allowing the sale and use of products already in the distribution system. https://t.co/7ZIsz7P0z4

In KS, the last date for sale is May 31 for soybean and June 30 for cotton.

Application cutoffs are still June 30 for soybean and July 30 for cotton.
