In recent years, Ustilaginoidea virens (Cooke) Tak has become more and more dangerous. Not only affect the rice yield and quality, but also endanger the health of humans and animals. To this end, I stood in the exploration of comprehensive prevention and control at the same time, conducted a multi-bacteria copper and other pharmaceutical comparison test. First, the test method 1 multi-bacteria copper 3 kg / mu dusting; 2 multi-bacteria copper 5 kg / mu dusting; 3 multi-bacteria copper 7 kg / mu dusting; 4 Bordeaux powder 5 kg / mu dusting ; 5 Jinggangmycin 0.3 kg / mu, 100 kg water spray; 6. Thiophanate-methyl 0.3 kg / mu,
