Drying may increase the residue content because of the concentration, but in sun-drying reduction may occur because of photo-degradation. For example, one brand of concentrated Bacillus thuringiensis recommends a rate of 1 to 3 teaspoons of Bt mixed with 1 gallon of water and applied to the peppers as a foliar spray to control hornworms.
