摘　　要：20%苯醚甲环唑水乳剂是防治柑桔炭疽病的优良药剂,2007～2008两年的田间药效试验表明,在柑桔(糖桔、贡柑)炭疽病发病初期用20%苯醚甲环唑水乳剂6 000倍、5 000倍、4 000倍液各喷药3～4次,对柑桔叶部炭疽病的防效为52.28%～81.09%,对柑桔果实炭疽病的防效为60.54%～84.43%,其中4 000倍液的防效显著优于对照药剂10%世高水分散粒剂2 500倍液,值得在生产上推广应用。20% Difenoconazole EW is good fungicide which shows specifically high activity against citrus anthracnose, the result of tests in fields showed that 20% Difenoconazole EW using 1：6 000, 1：5 000, 1：4 000 for 3 or 4 times gave a control effect of 52.28% to 81.09% against citrus leaf anthracnose, and 60.54% to 84.43% against citrus fruit anthracnose. 20% Difenoconazole EW using 1：4 000 had a better control effect than 10% Score WG using 1：2500, and it was worthy to be popularized on the growing practice.
