【Abstract】 The control effects of 4 fungicides on the peanut leaf diseases were studied.The results showed that the control effect of 35% Aimiao(difenoconazole + propiconazole) reached 64.8%,while those of azoxystcrobin and thiophanate methyl were not ideal and that of triadimefon was the worst.The application of Aimiao made the numbers of pods,full-pods and double-kernel pods per plant increase by 7.5,5.0 and 2.6 and the weight of hundred-pods and hundred-kernels increase by 12.4 g and 3.9 g,respectively;the yield,which was 351.33 kg per 666.7m2,increased by 112.83 kg with the increasing rate of 47.3% and the economic benefit increased by 477.15 yuan(R.M.B) compared with the control.Aimiao had good effects on controlling diseases and increasing yield.更多还原
