Soil disinfectant for preventing and controlling root rot of radix pseudo-ginseng and using method

Abstract

The invention discloses a soil disinfectant for preventing and controlling root rot of radix pseudo-ginseng and a using method. The soil disinfectant consists of 50 percent of ziram double-wettable powder, 72 percent of agricultural streptomycin sulphate soluble powder and 3 percent of phoxim granules. The soil disinfectant has good preventing and controlling effects on most fungus diseases, bacterial diseases and underground pest-insects. When the soil disinfectant is used for treating soil before sowing or transplanting the radix pseudo-ginseng, the germination rate is averagely 82.35 percent, and is 14.21 percent higher compared with 68.14 percent of average germination rate in contrast treatment without applying the soil disinfectant. The annual accumulative preventing and controllingeffect on the root rot of the radix pseudo-ginseng is 28.37 to 41.14 percent, averagely 34.54 percent. The soil disinfectant has the characteristics of low toxicity to people and animal and little residual toxicity, and can prevent and control dead seedling, root rot, underground pest-insects and the like of multiple crops such as Chinese medicinal materials, vegetables and the like.
