What are the control methods for leaf spot disease in geraniums?

Nursery Stock 0 views
Control of leaf spot disease in geraniums: 1. For small-scale plantings, remove diseased leaves by hand and burn them in a centralized manner. 2. Improve the growing environment. In areas with severe outbreaks, practice crop rotation, avoid planting too densely so as to allow good ventilation and light penetration, and drain standing water promptly. 3. During the disease period, spray with 100 to 150 times diluted Bordeaux mixture or 80% Captan wettable powder at 500 times dilution; you can also spray a mixture of 50% Thiophanate-methyl at 1000 times dilution and 80% Captan at 500 times dilution, or spray a 45% Chlorothalonil and carbendazim mixed suspension concentrate at 1000 times dilution, which gives better results than a single fungicide.
