Monitoring and Management of Thrips in Blueberries Posted by Ash Sial on Apr 17, 2018 Flower thrips are chronic pests of both southern highbush and rabbiteye blueberries in the southeastern United States. Thrips are minute (1 to 1.3 mm long) insects with slender body and usually yellowish to orange in color. Adults have long thin wings fringed with fine hairs (Figure 1). Females are generally larger than males. Both adults and nymphs have rasping and sucking mouthparts, which are used to extract cell sap from plant tissues.

On tissues already damaged by the freezes, two fungal pathogens of particular concern are Botrytis and Botryosphaeria.

Preliminary Estimation of Cotton Damages from Hurricane Michael Posted by Yangxuan Liu on Oct 22, 2018 By Yangxuan Liu and Amanda R. Smith Download the PDF version of this article.  Hurricane Michael unexpectedly gained power and quickly grew into a Category 4 storm overnight, which made it nearly impossible for Georgia cotton farmers to prepare and respond.

Peach Blog
Hurricane Michael, Peach Tree Damage, and Subsequent Phytophthora Root Rot Posted by Phil Brannen on Oct 9, 2018 This is largely a repeat blog post from last year.  I have changed the hurricane name, but otherwise, all remains the same. Hurricane Michael will probably move relatively quickly through Georgia, but I fear it will have substantial winds as it moves through.  It will likely cause damage to peach...
Court orders ban on chlorpyrifos Posted by Blaauw on Aug 15, 2018 Last week, a federal appeals court ordered the EPA to remove chlorpyrifos from sale in the United States within 60 days. While the threat of losing chlorpyrifos is not new and the ban is bound to happen eventually, I just wanted to give everyone a heads up that our management...
Plum Curculio and Scale Update Posted by Blaauw on Jun 27, 2018 I posted last week about scale management, but I wanted to send out a reminder about scale and an update for everyone that plum curculio (PC) adults are also active in the orchards (see image above taken last week). In blocks that still have fruit, if you are and have...

Peanut Blog
Insect Damage at Harvest Posted by on Oct 9, 2018 Very few things are as frustrating as delivering 5000+ pound per acre peanuts to the buying point and having them grade “Seg 2” because of insect injury, and when it happens there are usually a lot of questions. What caused it? Why did it happen? When did it happen? Could...
Conditions are Favorable for Southern Corn Rootworm Posted by on Aug 2, 2018 Conditions continue to be favorable for southern corn rootworm (SCR) development across much of Georgia’s 2018 peanut acreage. SCR is a pest that requires moist soil conditions, and we typically see rootworm infestations in fields with heavy soils and center pivot irrigation. The abundant rainfall in many areas this year...
27 July Peanut Insect Update: Potato leaf hoppers etc. Posted by on Jul 27, 2018 Insect activity is beginning to pick up in some of our Georgia peanut fields, and now is a really good time for growers who may not have a consultant or scout to get out and walk the crop. I have seen a mixed bag of caterpillars in my research plots...
It has been quiet; don’t fall asleep! Posted by on Jul 18, 2018 Insect pressure in Georgia’s 2018 peanut crop has been as low as I have seen since 2013. Several calls have come in over the last two weeks with folks asking what they are missing because it all just seems a little too quiet in the peanut patch. As we move...

Pecan Blog
Growers Must Adapt to An Evolving Pecan Industry Posted by Lenny Wells on Dec 11, 2018 This has been a year for a lot of sobering thought for Georgia pecan growers. We’ve had to deal with a lot. Trade wars, scab pressure, catastrophic storms, and perhaps most frustrating of all, depressed prices in the wake of losing half the state’s pecan crop. The storm is one...

Where Do We Go From Here? Posted by Lenny Wells on Nov 28, 2018 I’ve had a lot of questions recently about the long-term effects of the Hurricane on our pecan trees and the pecan crops we can expect in the next few years. Until recently our state has not had to endure the after-effects of a direct hit by a major hurricane. The...
A Dreary Harvest Continues For Some Posted by Lenny Wells on Nov 15, 2018 Now that it appears our two consecutive weeks of rain may have ended, growers who did not sustain devastating damage from Hurricane Michael will continue harvesting after the ground dries out a bit. This kind of rain has not likely been helpful to the quality of the nuts still on...

Spider Mite Damage on Strawberry Posted by on Mar 1, 2018 Shane Curry (Appling County Extension Agent) sent a photo of spider mites (see attached) on strawberry, and the numbers are tremendous.  Strawberry producers should be scouting for mites at this time, since the conditions have been warm enough for the mite population to explode in some areas, despite significant rainfall. ...
What to Look for Now Posted by on Mar 1, 2018 By now most of us should be well into our early fertility regime on plasticulture berries.  Beginning with about a 1/2 pound per acre per day (3.5 lbs. of N per week) to get the crop started.  As we move further into March we should gradually increase this rate to...

Hurricane Michael Update (Tim Coolong, Andre Da Silva, Bhabesh Dutta, and Greg Fonsah) Posted by Dutta on Oct 12, 2018 Damage to the fall vegetable industry caused by Hurricane Michael has thus far been significant for growers in Southwest Georgia.  Damage closely followed the path of the storm, with a line stretching from Seminole and Decatur counties up through Mitchell and Grady, Colquitt, Tift and even reaching fields in the Crisp county region.  Vegetable production regions near Lowndes and Echols Counties may have some loss but are expected to have escaped the worst of the damage.
