Phylloxera Insecticide Timing Study

Last week, Ginger Grier and I started an insecticide drench timing for phylloxera. This is an insect pest that invades pecan trees at bud break. The insect is very small and must be treated before the distinguishing wart symptoms appear on the leaves. This site has stuggled with the control of phylloxera for a long time which makes it a valuable site to test.

PhylloxeraTrialOne way to treat phylloxera is to include an insecticide with your first spray. However, the timing is difficult. Another route is to drench insecticide in the ground to be taken up by the tree. This can be done through irrigation, a sprayer tank, or mixing in a bucket.

We know the insecticide will translocate through the trees and be present in the stems at bud break; however, we do not know optimal timing of drench applications. In this study, we are applying imidacloprid as a soil drench in December, January, February and March. Thanks so Jake Ford and Keith Rucker who were very helpful getting us product on short notice. We will also test another insecticide that is waiting on label also for phylloxera.

UGA Extension Entomologist Dr. Will Hudson is attempting this study in Athens, so we will have information for both areas of the state. Phylloxera do not cause as much economical damage on the leaves as they do on the stems. Stem phylloxera is more of an issue if it is present.

UGA Crop Budgets Link

Seminole Crop E News

UGA Crop budgets are useful and here’s an updated link to get to them and to get to the Crop Comparison table as well.

I also updated my blogroll link that you can always easily click on on the left side of my blog homepage.

It will look like this, and once you get there the links are live to go where you want to.

Grazing Conference & Dairy Tours A Success


UGA Extension Forage Specialist Dr. Dennis Hancock and UGA Dairy Specialist Dr. Jillian Fain did a great job with the Mid-Atlantic Dairy Grazing Conference. The conference featured dairy tours which brought around 80 participants through Brooks and Thomas County. The tours were followed by a program at the Expo. Participants from Idaho, New Mexico, New York, Wisconsin, Michigan, and all across the Southeast came through the county on November 12th. The tours began at Brook Co Dairy outside of Quitman, then proceeded to Jumping Gully in Pavo. They stopped for lunch in Thomasville then visited Sweet Grass Dairy on their way out. Here are some of the photos above and below:



Additionally, the Progressive Forage Grower Magazine did an article on the program called New Directions for Grazing Dairies: Using Silage as a Supplement, which features photos from Sweet Grass Dairy and Dr. Hancock’s “dirty underwear” demonstration which illustrates the effects of organic matter in the soil.
