How to use carbendazim? What diseases can carbendazim control? How to use the effect is good? Please introduce carbendazim, which belongs to benzimidazole, is a kind of high-efficiency and low-toxic internal absorption fungicide, because it has obvious top transport performance, it is also used for seed dressing and soil watering in addition to leaf spray; it is a broad-spectrum internal absorption fungicide, absorbed by seeds, roots and leaves, can be transmitted in crops, has protective and therapeutic effects, and has a long residual period. It has activity against many pathogens of ascomycetes, basidiomycetes and semi-known bacteria, but has no activity against oomycetes, Alternaria, Alternaria and bacteria. Can be used in fruit trees, vegetables, flowers and field crop disease control, common carbendazim has 25%, 50% wettable powder, 40% suspension agent and so on. Carbendazim can control diseases such as pear scab, apple brown spot, grape black pox / white rot / anthracnose, tomato early blight, melon powdery mildew, sugar beet brown spot, melon Fusarium wilt, cotton seedling blight / anthracnose, peanut black spot, stem rot, wheat scab, rice sheath blight, sweet potato black spot, rose leaf spot, orchid anthracnose and leaf spot. Detailed usage can be referred to the following: carbendazim usage: 1, tomato early blight, melon powdery mildew, sugar beet brown spot: from the initial stage of the disease, with 50% wettable powder 800-1000 times liquid, spray control every 7-10 days, continuous spray 3-5 times, can be prevented. 2. Fusarium wilt control of cucumber, watermelon and other melons before transplanting: 1-1.5kg of 50% wettable powder per mu, 25-30kg of fine soil, evenly sprinkled in the planting ditch or hole, and then irrigated with 1000 times of 50% wettable powder during the melon setting period. 3. Cotton seedling blight and anthracnose: use 50% wettable powder 1 kg, 10-20 kg water, 100 kg cotton seeds, sow seeds after 6 hours, or soak seeds with 250 times 50% wettable powder solution for 24 hours, dry and sow seeds. 4. Peanut black spot and stem rot: use 50% wettable powder 0.5-1 kg, peanut seeds 100 kg, mix well and sow seeds. 5. Wheat scab: at the peak heading stage of wheat, 50% wettable powder is sprayed with 5-1000 times liquid and sprayed again every 5-7 days. Spray 75-100 kg per mu each time. 6. Rice sheath blight: the rice sheath blight was sprayed once at the end of tillering stage and booting stage with 50% wettable powder. 7. Sweet potato black spot: before transplanting, soak the stem base of sweet potato seedlings with 3000-4000 times liquid of 50% wettable powder for 5 minutes. 8, flower usage: according to the incidence, 50% wettable powder 500-1000 times liquid spray can prevent and cure powdery mildew of all kinds of flowers and rose brown spot, orchid leaf spot, orchid anthracnose, leaf spot and so on. 9. Pear scab: during the budding period and after flowering, 50% wettable powder 500 times was sprayed once, and then sprayed every 7-10 days for 2-3 times in a row. 10. Apple brown spot: spray control with 500-800 times of 50% wettable powder from the early stage of apple disease, and spray again 7-10 days later. 11. Grape black pox, white rot, anthracnose: spray 50% wettable powder 1000 times every 10-15 days from leaf spreading to fruit coloring. Matters needing attention: first, it is the choice of carbendazim. At present, most of the carbendazim sold in the market are wettable powder and gel suspension. No matter which one you choose, you can not choose compound carbendazim, because compound carbendazim can inhibit the growth of mycelium. In addition, we should pay attention to the expiration date of the product. It is better to use those with a delivery date of less than one year. For more than one year, the dosage should be increased appropriately, and the use of those with complete failure should be prohibited. Second, it is the method of mixing carbendazim. When carbendazim is mixed into the culture material, the medicine can be dissolved in enough water first, and then gradually mixed into the material, stirring evenly to avoid spot contamination. Control the dosage of carbendazim. If the dosage is blindly increased, not only the cost will be increased, but also the mycelium growth will be affected. At the same time, the accumulation of carbendazim in the fruiting body is large, which will cause food contamination. Third, it is the taboo of carbendazim: some edible fungi such as fungus, mushroom and hericium Erinaceus are extremely sensitive to carbendazim and should be avoided. In addition, it should be noted that the use of carbendazim must pay attention to control the dose to prevent residual overdose. The effect and usage of paclobutrazol of Ningnanmycin
