After through different local throughout the country tests, draw, tetrachloro insect amide and dimehypo, thiocyclam, desinsection list composite rear to the preventive effect of the common insects such as the rice leaf roller in various crop, rice fulgorid, striped rice borer, paddy stem borer, leaf miner, cabbage caterpillar, diamond-back moth, thrips or aphid all more than 95%, be better than single dose preventive effect, synergistic effect is obvious.
