Research tells us that peanuts planted in Georgia from this point forward should be at reduced risk of thrips infestation and Tomato Spotted Wilt infection. Nevertheless, we continue to catch adult tobacco thrips which means they are still moving around and can infest peanut fields as the crop emerges. My April planted thrips trials currently…

Thrips numbers on our traps have remained relatively steady for the last three weeks, though we did see a spike last week in Colquitt County. My first thrips trials are just now emerging from the ground, and I have not heard any reports of thrips control problems on early planted peanut as of today. I…

Tobacco thrips numbers declined at five of our six trapping locations last week. This does not mean that thrips flights are over or that peanuts are safe from injury. Thrips dispersal is still occurring, and seedling peanuts emerging over the next couple of weeks will be exposed to adult thrips and the risk of feeding…

Peanut planting is about to get real serious in Georgia, and we are once again monitoring tobacco thrips flight activity for the spring planting season. Producers who have already planted or who are planting this week should be watching peanut fields closely for thrips and signs of thrips injury as seedlings emerge. We saw thrips…

Thrips numbers on our traps have mostly been trending downward since 18 May. This pattern is typical of what we have seen in Georgia over the last few years. Many if not most of our peanut acres are getting to the point at which thrips injury is no longer a concern. Though the larger “thrips…

The damage progression over the last seven days in our UGA thrips trials was not as severe as I expected. On a 0 to 10 damage scale (0= no damage, 10 = dead plant) untreated check plots that were planted on 29 April averaged a 4.8 on 17 May. Damage ratings for the same untreated…

It will come as no surprise to anyone who has been walking through peanut and cotton fields over the last seven days, but tobacco thrips are still on the move. While there is no definitive answer to the question of when should we pull the trigger on a foliar insecticide treatment for thrips in peanut,…

More peanuts are emerging this week, and as expected the phone calls and text messages about thrips have started coming more frequently. Fortunately not many problems have been reported in fields where recommended soil insecticides were used at planting. I have heard of some severe injury in volunteer peanuts and fields where there was a…

Adult tobacco thrips continued to move over the last week. The first of our thrips trials in peanut should be emerging this week, and we will provide updates on the actual pressure we are seeing. In the mean time, growers are encouraged to keep an eye on fields for thrips and thrips injury. These data…

Tobacco thrips were present on sticky traps at all locations last week. While the numbers do not seem dramatically high, they are similar to capture rates in previous years during periods of thrips dispersal. Most growers are using some form of at-plant insecticide for thrips control, but if no insecticide was used or if there…
