Citrus anthracnose is a latent enemy. As long as the tree is weak and the climate is suitable, it will erupt, and once it breaks out, even if rescue measures are taken immediately, the recovery of the tree will take one or two years.

In dozens of domestic and foreign pesticide fungicides, the efficacy comparison test was carried out.
After measurement, the best bactericidal effect is prochloraz, followed by triazole pesticides such as difenoconazole.
Recommended formula 25% prochloraz cream 1000 times +80% Dasheng wettable powder 500 times
Prochloraz can quickly kill anthrax, and Dasheng is wearing a protective clothing like a tribute tree, which can inhibit the infection of bacteria in the body and resist the invasion of external bacteria.
