1. Control of vegetable diseases
For seedling damping-off and seedling blight, mix 160 g of 2.5% powder with 20 times its amount of fine soil to prepare medicated soil and spread it evenly;
For potato ring rot, use 75% soluble powder at 0.3%-0.5% of the seed potato weight to dress the seed tubers; for cucumber and watermelon damping-off and Fusarium wilt, use 207-400 g of 75% soluble powder per mu, dilute with 75-100 kg of water and spray the stem base or drench the roots, spraying 2-3 times continuously at the early stage of disease onset; for downy mildew of Chinese cabbage and cucumber, and anthracnose of tomato and eggplant, spray with a 500-1000 times dilution of 75% soluble powder.

2. Control of cotton seedling diseases: dress seed with 500 g of 95% wettable powder per 100 kg.
3. Control of tobacco black shank: mix 350 g of 95% wettable powder per mu with 15-25 kg of fine soil, spread it at the base of the tobacco plants and cover with soil immediately.
4. Control of rice seedling damping-off, black root disease and seedling rot
Per mu of seedling field, dress seed with 921 g of 95% soluble powder; use 14 kg/ha of 95% soluble powder, diluted with water and poured or sprayed.
5. Control of damping-off and black root disease of pine and fir seedlings
Dress seed with 147.4-368.4 g of 95% soluble powder per 100 kg of seed.
6. For tobacco black shank, mix 5.25 kg/ha of 95% soluble powder with 225-300 kg of fine soil; at transplanting and before ridging, scatter the medicated soil around the base of the tobacco seedlings and cover with soil immediately. Alternatively, spray the stem base and surrounding soil surface of the tobacco seedlings with a 500 times dilution of 95% soluble powder, using 1500 kg/ha of the liquid, spraying once every 15 d for a total of 3 sprays.
7. Diseases of wheat, millet and potato: dress 100 kg of seed with 220 g of 95% soluble powder to control wheat bunt, millet kernel smut, potato ring rot, etc.
