Please be aware that there have been several reports of worms in peanuts. \u00a0The foliage feeders that I have observed were Fall Armyworm caterpillars. \u00a0The treatment threshold for foliage feeding caterpillars in peanuts is 4-8 larvae\/row ft. \u00a0The low level of four caterpillars\/row ft. should be used if the peanuts are small and\/or stressed. \u00a0The higher level of eight caterpillars\/row ft. may be used if the middles have lapped or close to lapping. \u00a0Also, the higher threshold level is acceptable if \u00a0the peanuts are healthy and vigorously growing. \u00a0Depending upon the type of \u00a0foliage feeder present, there are numerous insecticide treatment options. \u00a0However, consideration of effect on beneficial insect population should be used during insecticide selection.<\/p>\n

Dr. Mark Abney (UGA Peanut Entomologist) has reported Lesser Cornstalk Borer (LCB) activity in South Georgia. \u00a0Fields will need to be scouted to determine the presence of LCB. \u00a0Also, be observant of LCB moths from the peanut foliage as you walk fields. \u00a0Keep in mind, that LCB thrives in hot, dry conditions and light sandy soils. \u00a0When scouting for LCB, check several locations in each field by pulling and examining one to three plants at each location. \u00a0By pulling up the plant, you can more easily locate the caterpillars. \u00a0When examining the plants look for larvae, feeding damage, and silken tubes covered with soil. \u00a0It may be challenging to find the larvae because they are often inside the silk tubes or inside the stems of the peanut plant.<\/p>\n

Currently, the only recommended product for LCB control is granular Chlorpyrifos (Lorsban 15G). \u00a0The liquid formulations of Chlorpyrifos are not registered for foliar application in peanuts. \u00a0Please remember that granular chlorpyrifos cannot be applied by airplane to peanuts. To be effective granular chlorpyrifos must have rainfall or irrigation. \u00a0The application of Chlorpyrifos will kill beneficial insects and increase the risk of foliage feeding caterpillars and spider mites. \u00a0Research conducted at UGA has found that foliar insecticides do not provide control of LCB. \u00a0Dr. Mark Abney is currently testing a variety of foliar insecticides against LCB and we will provide the results when available. \u00a0LCB populations can be slowed by rainfall and cooler temperatures. \u00a0But, once an outbreak of LCB has occured, we cannot depend on rainfall alleviating the situation. \u00a0Lesser cornstalk borer is probably the most serious pest of peanuts in Georgia. \u00a0It is important to observe fields for moth activity and examine plants regularly.<\/p>\n
