Polysulfide suspension is the new carbendazim and sulfur (1: 1) mixture of new formulations. It has the advantages of high efficiency, broad spectrum, longer duration. Now 1982 ~ 1984 prevention and control of rice blast and sheath blight test and demonstration results are reported below. First, the effect of prevention and control of rice blast Ye leaf blast, 40% polysulfide suspension (0.4 ~ 0.5 kg / mu) control effect of 71.3 ~ 99.6%, better than carbendazim WP (0.4 ~ 0.5 kg / mu ), Different blast net (0.2 kg / acre), gram blast (0.25 kg / acre) and Japan’s rice blast (0.2 kg / acre) effect. Prevention panicle blast, the effect is also more significant. Comprehensive test results around, respectively, in the breach of rice and heading date, each Kai
