Which diseases can carbendazim control
(Agricultural Wealth Network) Carbendazim is a broad-spectrum systemic fungicide with systemic therapeutic and protective effects. The pure product is a white crystalline solid, and the technical product is a brown powder. Carbendazim is widely used for the control of diseases of fruit trees, vegetables, flowers and field crops. The formulations are 25% and 50% wettable powders, 40% suspension concentrate, etc. The control targets and application techniques are as follows:
(1) Control of fruit tree diseases:
① At the bud break stage and after petal fall of pear trees, spray once with a 500-fold dilution of 50% wettable powder, then spray once every 7-10 days, for 2-3 consecutive times, to control pear scab.
② Use a 500-800 fold dilution of 50% wettable powder, starting spraying from the early stage of disease onset in apples, and spray once more after 7-10 days, to control apple brown spot.
③ From after grape leaf unfolding to before fruit coloring, spray every 10-15 days with a 500-1000 fold dilution of 50% wettable powder, giving good control of grape black pox, white rot and anthracnose.
(2) Control of vegetable diseases:
① Starting from the early stage of disease onset, use a 800-1000 fold dilution of 50% wettable powder, spraying once every 7-10 days, for 3-5 consecutive sprays, to control tomato early blight, cucurbit powdery mildew and beet brown spot.
② Before transplanting and planting cucurbits such as cucumber and watermelon, use 1-1.5 kg of 50% wettable powder per mu, mix well with 25-30 kg of fine soil, and spread evenly in the planting furrows or holes; at the fruiting stage, drench the roots again with a 1000-fold dilution of 50% wettable powder, to control cucurbit fusarium wilt.
(3) Control of cotton diseases: Use 1 kg of 50% wettable powder, add 10-20 kg of water, mix with 100 kg of cotton seed, pile and cover for 6 hours before sowing, or soak the seed for 24 hours in a 250-fold dilution of 50% wettable powder, dry and sow, to control cotton seedling damping-off and anthracnose.
(4) Control of peanut diseases: Use 0.5-1 kg of 50% wettable powder with 100 kg of peanut seed, mix well and sow, to control peanut leaf spot, stem rot, etc.
(5) Control of wheat fusarium head blight: At the peak heading stage of wheat, spray with a 500-1000 fold dilution of 50% wettable powder, and spray once more after 5-7 days. Spray 75-100 kg of spray solution per mu each time.
(6) Control of rice sheath blight: Use a 500-1000 fold dilution of 50% wettable powder, spraying once each at the late tillering stage and the booting stage of rice.
(7) Control of sweet potato black spot: Before transplanting, soak the base of sweet potato seedling stems for 5 minutes in a 3000-4000 fold dilution of 50% wettable powder.
(8) Control of flower diseases: According to the incidence of disease, spray with a 500-1000 fold dilution of 50% wettable powder, to control powdery mildew of various flowers as well as rose brown spot, clivia leaf spot, orchid anthracnose, leaf spot, etc.
