How to control Eucalyptus grandis leaf blight
The control methods for Eucalyptus grandis leaf scorch disease are as follows:
1. Choose a good nursery site. Select a plot where this type of disease has not occurred as the nursery site, or if unavoidable, the soil must be disinfected before raising seedlings. Disinfectant drugs can be selected from fungicides such as junduqing, potassium permanganate, zineb, etc.
2. In diseased areas, diseased and dead branches on the trees in young forests should be removed in a timely manner, fallen diseased leaves on the ground should be swept up, and they should be gathered and burned.
3. In severely diseased areas, fungicides can be sprayed for control. The drugs with relatively good control effects are, in order, junduqing, sukelin, and metalaxyl mancozeb. The concentration used is generally a 600—800-fold solution.
