RE: Insecticide spraying

HOPE THIS COMES THRU, it's a Drag n Drop. Bioassay studies were conducted to evaluate WARRIOR rainfastness. Cotton plants were greenhouse grown and treated with WARRIOR and WARRIOR EC. Treated plants were allowed to dry for three hours. Then half of these plants were subjected to one inch of simulated rainfall. Well exposed leaves were taken from treated plants with no simulated rainfall and compared to similar leaves from treated plants receiving simulated rainfall using a bioassay for tobacco budworm mortality.
	Additional bioassays were conducted to evaluate effects of dew and high humidity on efficacy of WARRIOR. All tests indicated that neither dew nor high humidity have any impact on efficacy.

How does one balance the need to overhead water every day or two with the need to spray for cuke beetles & SVB? How "waterproof", if waterproof at all, is Warrior T, Sevin?Is each washed off  by water quickly or slowly? In other words how much residual insecticide is left after say an hour of overhead watering? Thanks!
