The extremely serious soil-borne disease has finally become a nemesis. Yunnan Xingyao Biological Products Factory, Yunnan Agricultural University's Plant Pathology Laboratory and China Agricultural University's Plant Protection College's Department of Health and Prevention, jointly developed a few days ago a microbial pesticide product "hundred resistance", in the development and application of microbial pesticide bactericide in our country has taken important steps. The soil-borne diseases of crops are a kind of plant diseases that are widely distributed, severely endangered, and difficult to prevent. They are widespread in countries throughout the world and are particularly serious in China. The annual incidence area amounts to 100 million mu, and the annual occurrence of soil-borne diseases in Yunnan exceeds 4 million mu. The traditional methods of chemical control are not only costly, polluting, destroying the soil ecology, but also causing excessive residues of harmful substances in agricultural products. Since 1998, Yunnan Province has listed microbiological pesticides as a Provincial School Science and Technology Cooperation Project of the Provincial Institute of Science and Technology and has organized research efforts. According to experts, the newly developed “Hundred Resistance†is a broad-spectrum fungicide, which mainly protects plants from infection by pathogens through the nutrient competition of the active ingredient “Bacillus subtilis B908†and the occupation of sites. The pathogenic bacteria are treated with bacteria to achieve the purpose of preventing and controlling diseases and promoting yield increase. "Hundred resistance" as a kind of bacterial microbiological living pesticide, has the characteristics of low cost, good effect, safety and stability, does not harm the environment, does not produce phytotoxicity to crops, etc., and is susceptible to tobacco, Panax notoginseng, flowers, wheat, cabbage, etc. The soil-transmitted crops have a good control effect, and the control effect against rice sheath blight is over 70%, making it the first bacillus bactericide registered in rice. Since last year, this achievement has been tested and demonstrated in Yunnan, Shandong, and Hubei over 70,000 mu. It has achieved significant disease-control and yield-increasing effects. This year, it plans to promote 200,000 mu and will promote it in Thailand, Vietnam and other countries. Experts believe that the production and development technology of “Hundred Resistance†ranks the leading domestic level and has broad application prospects, which will certainly produce significant social and ecological effects.
