Georgia produces about 40% of the U.S. supply of peanuts, with annual yields from 2000-2008 ranging from 1.3 billion – 3.4 billion pounds. Peanut pests are many and varied and often vary from year to year. Peanuts are an ideal crop for IPM. Host plant resistance has great potential to reduce pesticide inputs and increase peanut profitability.
Tomato Spotted Wilt Virus
The most important problems in recent years were diseases and thrips species that vector tomato spotted wilt virus (TSWV), and lepidopterous defoliators in early season. Recent released cultivars have moderate to high levels of resistance and/or tolerance to leaf spot pathogens. The use of partial resistance to the leaf spot pathogens represents a means for significantly reducing the amount of fungicides required for peanut production. Further, the use of a resistant cultivar is the single most important factor in control of TSWV.
A "risk assessment index," developed by the Peanut Team, has been a very valuable tool for helping growers and advisors make decisions that reduced risk for a given farm and situation. For more information on Peanut Team activities, please visit the UGA Extension Peanut website.
