“It’s a hot mix, but we have not pulled any weeds. We followed that on June 13 with Basagran and Dual. We’re following a standard fungicide program on these peanuts. It’s critical that we continue to update our research on new varieties,” he says.

Also at Field Day, members of the UGA Cotton Team reported on their long-term fertility, insect and agronomy trials.

“Potassium on cotton continues to be a big issue,” says soil fertility specialist Glen Harris. “We’re looking at split applications of potassium and foliar applications, early and late, on six varieties.

“Last year, the varieties did seem to react differently between early and late foliar applications, so we’re trying to see if that’ll happen again. We’re also looking at a lot of different nitrogen materials,” he says.

Extension entomologist Phillip Roberts says most of his efforts at Expo are efficacy trials to compare different insecticides on whichever pest might be present at the time.

“We have thresholds for all our common pests, and we want to advise growers on what’ll do a good job for them. In addition to looking at the effect on target pests, we also look at the impact on beneficial insects or how a certain pesticide is likely to flare another pest.

“We know that insecticide selection can cause a certain pest to be more of a problem. We encourage our scouts to be aware of uncommon pests as well as the more common ones,” says Roberts.

Agronomist Guy Collins says he’s trying to identify the cotton varieties that perform consistently in the top. “We also want to learn how to better manage these new varieties. Some are earlier maturing than DPL 555. We’re also looking at irrigation and its effect on different varieties. We’re learning how to position these varieties.”
