| Abstract: | 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. |
