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…

As I walked through my test plots and a few commercial peanut fields this week I noticed that we are starting to see some potato leafhoppers and very early hopper burn. UGA Extension agent Rome Ethredge in Decatur County also mentioned that there was some heavy leafhopper pressure in at…

Though thrips numbers on our traps were never high, there were two distinct peaks: one in early April and another in mid-May. Numbers remained above above 0 at all sample locations for a couple weeks after the May peak, but they fell off this week. We saw plenty of peanut…

Threecornered alfalfa hopper (TCAH) is commonly seen in Georgia peanut fields each year. This insect is highly mobile as an adult, and large numbers can very quickly move into and out of a field. The adults are easily identified by their triangular shape and bright green coloration, and they will…

We are still seeing plenty of thrips in our test plots on the UGA Tifton Campus. The progression of the infestation and feeding damage at the Bowen farm is following a predictable pattern. Damage ratings a week ago ranged from 2 to 4.8, and this week ratings ranged from 2.3…

We continue to check our thrips traps every Friday. After an early April bump in activity, captures of tobacco thrips dropped and stayed low until last week when numbers were up again. Thrips are definitely present in our peanut fields, and the trap data indicate that adults are moving. This…

We have a couple peanut thrips trials that were planted on 24 April on the UGA Bowen Farm in Tifton that are currently experiencing moderate thrips pressure. These trials have treatments that include phorate (Thimet) in-furrow, imidacloprid (Admire Pro or Velum Total) in-furrow, thiamethoxam seed treatment (CruiserMaxx Peanut) and an…

There were very few tobacco thrips on our traps last week. So what does that mean to growers? All it means to me is that there was no large migration/dispersal of thrips last week. It does not mean that peanuts that emerged two weeks ago will not have thrips on…

I expected to see a bump in tobacco thrips numbers last week after several days of drier weather, but it was not to be. Nevertheless, we are seeing thrips and thrips damage on volunteer and some early planted peanut. A model for forecasting thrips dispersal developed at North Carolina State…

Tobacco thrips numbers spiked on yellow sticky traps on 10 April, but numbers were down again on 17 April (last Friday). The drop in trap captures is likely related to the abundant rain that fell last week. What does this mean for growers?
