Background
The rice blast is commonly called as cancer of rice, and the yield of crops is reduced by 45-50% even the crops are completely harvested when the rice blast is serious. The yield reduction of rice of more than 500 million hectares still exists every year as far as China today, the direct loss of rice reaches 15 hundred million to 30 hundred million kilograms, and the direct loss of rice reaches 20 hundred million to 40 hundred million yuan in terms of RMB;
at present, the common method for farmers to control rice blast is as follows: the pesticide is compounded by tricyclazole, chlorobromocyanuric acid, amobam, isoprothiolane missible oil and isorice tricyclazole missible oil, has multiple varieties and large concentration difference, and is difficult for farmers to accurately master the concentration, so that the prevention and treatment effect is not ideal, the price is higher, the use is extremely inconvenient, especially, the pesticide is easy to cause the drug resistance of pathogenic bacteria, the prevention and treatment effect is continuously reduced, and the improper use can bring considerable serious harm to the ecological environment and the human health. In addition, although some biological agents, typically validamycin, bacillus subtilis, etc., have been developed, the stability of quality and the selectivity of propagation thereof make the use effect less than ideal;
it should be noted that although agricultural breeding experts have conducted a lot of research on enhancing disease resistance of crops, high nitrogen must be supplied when pursuing high yield, and in addition, the high temperature and high humidity environment in the vigorous growth period of rice, the factors of wide territory, variety adaptation, temperature difference, weather condition variability and the like in China exist, so that the problems of high quality, high yield and high resistance are solved in a package, and a lot of basic research work is needed.
