The 2015 Peanut IPM Insect Control Guide (IPM-0360) is up on the ACES website. The first two pages provide some highlights and hot topics.
Updates in this issue include a detailed discussion for THRIPS management since it was a major concern in 2014. Among the control options, the latest one is the use of SPINETORAM (RADIANT) SC that has excellent efficacy against thrips and caterpillar pests. Radiant acts as contact and stomach poison with translaminar action when applied on foliage.
Radiant belongs to IRAC Class 5 which has a different mode of action from neonicotinoids belonging to IRAC Class 4. Spinetoram or Radiant is more selective and lower-risk insecticide compared to synthetic pyrethroids. So, this insecticide can serve as a rotation partner with pyrethroids when producers want to target a broad range of caterpillar pests.
Depending on the season, stay alert for lesser cornstalk borers (LCB) and cowpea aphids that are opportunistic pests during hot and dry weather. Our insect monitoring program using sticky wing traps always gets plenty of LCB moths in southeast Alabama probably due to the presence of peanut and other host crops. So, stay alert and follow the Alabama Extension IPM recommendations and pest alerts that have been developed in collaboration with crop advisors to serve you better!
