If nematodes are also a problem, there are a couple of varieties that have resistance to both problems. Free barbecue lunch to all participants. Ask for Charlotte or Marlyn. Lima beans and Snap Beans. Potato leafhopper adults and nymphs continue to be very active in beans throughout the state.
Weather conditions continue to be favorable for damage, especially in drought stressed fields.
The treatment threshold is 5 per sweep during prebloom and 10 per sweep during bloom. In snap beans, this threshold should be reduced by one-half if thrips are also present, especially if the field is drought stressed. Asana, Lannate or Orthene will provide control of both pests. Mites have exploded due to the hot, dry weather. Dimethoate is still the first choice for mite control but needs to be applied before mites explode.
