LCB

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…

There continue to be lesser cornstalk borers (LCB) in Georgia peanut fields, and I do not see any reason that should change over the next few weeks. Interestingly, most of the heavy pressure has not been in the Southwest but in the middle and eastern portions of South GA. I expect that some of the…

I mentioned last week that we were getting some reports of lesser cornstalk borer (LCB) in peanut, and that hot, dry conditions could result in more pressure. Over the last three days I have received a number of calls and emails from agents, growers, and consultants indicating that LCB is becoming more prevalent in peanut…

There has been no rain in Tift County this week, and as I walked my plots and a commercial field this morning I saw a few lesser cornstalk borer larvae in the sandy parts of non-irrigated fields. High temperatures combined with dry conditions favor three of the most troublesome arthropod pests of peanut: lesser cornstalk…

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…

“What are you seeing?” is a question I have been getting and giving quite a bit the last couple weeks. The answer is a mixed bag of insects and a lot of variation in the level of pressure from field to field. We have seen three cornered alfalfa hopper (TCAH) numbers increase over the last…

Lesser cornstalk borer (LCB) is one of the most damaging and difficult to control pests in peanut. This insect is very fresh on the minds of many growers after a season of widespread heavy infestations in 2014. LCB is a sporadic pest in much of GA, and while outbreak populations in back to back years…

We are approaching mid-August, and the insects and mites are staying with us. The two that concern me most continue to be lesser cornstalk borer (LCB) and two spotted spider mite. I have seen several spots in recent days where LCB populations are high enough to kill peanut plants. The pattern has been the same…

Over the last several weeks there have been a lot of discussions in Georgia about using foliar insecticide applications to target lesser cornstalk borer (LCB). The major constraint to this approach is less about the efficacy of the insecticides than it is about our inability to get products to the pest. LCB larvae spend most…

Lesser cornstalk borer (LCB) is probably the most serious pest of peanut in Georgia, and we are seeing quite a bit of LCB activity. This pest thrives in hot, dry conditions and light sandy soils…something we have plenty of in South GA right now. Fields need to be scouted to determine if LCB is present.
