Catkin (male flower) production has been pretty heavy so far. A large catkin crop does not guarantee a large production of flowers, but most times we have heavy catkin production, we do have some flowers. I had the chance to look at many different cultivars this week. The first thing we noticed is that flowers…

From Dr. Lenny Wells You may notice some nut drop in your orchards at this time. This can occur for a number of reasons, including rainfall after a long hot, dry period and natural drop on certain varieties. One thing we are seeing at the moment is drop from nut curculio. The damage from nut…

Below is a reminder for UGA recommendations on treatment: Plant Bug Thresholds: Cotton plants retain less than 80% pinhead squares and there are a reasonable number of bugs present.

Thrips initially feed on the underside of cotyledons; damaged cotyledons will appear silvery on the lower surface of cotyledons.

I was in the hayfield today collecting samples of Bermudagrass Stem Magget for post doc Dr. Lisa Baxter. In doing my sweet net portion, it was obvious the number of armyworms present.

The worst thing we can do right now is add an insecticide just because we’re going over the field. I’ve looked a many cotton fields this week and am almost surprised to not see hits from stink bugs. I know there are some around, but pay attention to thresholds. Remember my post about peanut insects…

We’re seeing “bronzing” of bermudagrass stem maggot around Wilcox County. This is typical of bermudagrass stem maggot. We’ve had reports of damage for over 2 weeks. I’m seeing damage from Pineview to Pitts to south in the county. It’s definitely showed up a little earlier than normal. Colquitt County Agent Jeremy Kichler has also noted it earlier at their Expo plots. We…
