Ginger spot disease is a fungal disease. In addition to agricultural measures, such as crop rotation and field removal of diseased bodies, it is necessary to adopt chemical control at the early stage of disease, which can be used as a 600 times solution of 20% Runicillus sp. Or 50% Tsui Bei dry suspension agent 2500 ~ 4000 times, or 70% thiophanate-methyl WP 1000 times spray, spray every 7 to 10 days, and even spray 3 to 5 times. The above medicines can be used interchangeably, and the foliar fertilizers can be properly added in the liquid medicine when spraying. For example, Tianda 2116 can make the leaves turn green and thicken, enhance photosynthesis, and increase plant disease resistance.
