Texas Agricultural Extension Service Peanut Production Texas ranks 2nd in U.S. peanut production. There are no commercial replacements for aldicarb, except organophosphates or other carbamates. Weeds Weeds are the most common pest encountered by peanut growers. Weeds reduce grower profits by competing for sunlight, water and nutrients.
Weeds also host pathogens, viruses, and insects plus disrupt harvesting operations.
One-third of the acreage is rotated to other crops for two or more years to reduce weed problems. The most troublesome weeds in peanuts are pigweed, yellow nutsedge, morningglory, johnsongrass, nightshade, Texas panicum, sunflower, Russian thistle, and eclipta. While these herbicides are not in the Phase I of FQPA-targeted products, they will be eventually reviewed. Outlook A major concern is the lack of effective soil-applied insecticides and nematicides. Diseases continue to be a problem, especially viruses transmitted by insects.
