The invention relates to a photolysis-resistant
pesticide and application thereof. The photolysis-resistant
pesticide comprises the following components in percentages in weight: 0.1-90 percent photosensitive
pesticide active ingredient, 0.2-30 percent water-soluble
ultraviolet absorbent, 0.2-20 percent oil-soluble
ultraviolet absorbent, 0.2-20 percent
antioxidant, 1-20 percent surfactant and 4-95 percent
solvent or carrier. According to the photolysis-resistant pesticide, the water-soluble
ultraviolet absorbent and the oil-soluble ultraviolet absorbent are adopted for synergistic effect, and simultaneously the
antioxidant is added; and therefore, at least 30 percent, even more than 50 percent,
ultraviolet light can be absorbed, the photolysis-resistance of the photosensitive pesticide
active ingredient can be improved, and the half-life of the pesticide can be prolonged; namely, the
exposure durations of pests (
bacteria, weeds or mites and the like) under the pesticide
atmosphere are increased, the using effect of the pesticide is enhanced, and the use amount of the pesticide is reduced; and the photolysis-resistant pesticide can be used for preventing and controlling various pests and diseases of plants, especially crops.
