Abstract:
Phytophthora root rot of soybean is one of soybean diseases that difficult to prevent.So it′s necessary to use integrated ways to protect soybean from Phytophthora root rot.The field trial of fixed point investigation combining with small section experiments was conducted to process a integrated control measures from resistant varieties,chemicals and biocontrol measures.The result indicated that using resistant variety was the most effective way with the lowest cost.The control effect of the variety Hefeng 34 was up to 98%.In the chemical control experiments soybean seed surface-coated 26 and metalaxy provided by Chinese Academy of Science and 58% Metalaxyl had remarkable prevention effects,which was 83.7% and 70.1%,respectively,the increased production percentage comparing to control was 12.7% and 10.1%,respectively.In the biological control experiments,seven kinds of biological medicament were chosen and ten treatments were set.The result indicated that 45 mg?L-1 harpins protein which was provided by Nanjing Agricultural University had the best control efficacy.The average disease incidence was 0.12%,and the effect of control was up to 75%.The average increasing production was 7%.
