Abstract:

The control effects of seven different types of biological pesticide on soybean Phytophthora root rot were compared in this research. The incidence and prevention efficiency of phytophthora root rat, as well as soybean yield were determined. The results showed that 45 mg·L^-1Harpins protein from Nanjing Agricultural University had the best control effect，the average incidence of Phytophthora root rot of was 0.12%，the prevention effect reached 75% and average yield was 7% higher than CK.The second was “818” fermentation liquid provided by the Chinese Academy of Agricultural Sciences,the prevention effect reached 58.3%.The control effect of 45 mg·L^-1 Harpins protein and “818” fermentation liquid were extremely significant different with CK.
