The function of carbendazim and matters needing attention in use

Carbendazim, also known as Mian Wei Ling, etc., its industrial products are light brown powder, which is stable to heat and stable under alkaline conditions. It has low toxicity to people and animals. The commonly used dosage forms in orchards are 25% and 50% carbendazim wettable powder, and 40% carbendazim suspension. The following editor will introduce the role of carbendazim and matters needing attention.

What are the functions of carbendazim?

Carbendazim is a broad-spectrum internal absorption fungicide, which can be absorbed by plant seeds, roots and leaves and can be transported in plant tissues. It has protective and therapeutic effects. With 50% carbendazim 800-1000 times liquid, it can control many kinds of fungal diseases on jujube, such as anthracnose, spot disease, pulp rotten fruit disease and so on. In order to improve the control effect of fruit diseases, 0.03%-0.05% adhesive can be added to the solution.

Carbendazim can be mixed with general fungicides, but it should be mixed with insecticides and acaricides, and it should not be mixed with strong alkaline drugs and copper-containing preparations. Continuous use of carbendazim is easy to cause drug resistance of pathogens, so it should be used alternately or mixed with other agents. Because of the cross-resistance between carbendazim and carbendazim, it is not suitable to be used alternately with carbendazim.

Points for attention in the use of carbendazim

1. Stop using vegetables 5 days before harvest. This agent should not be mixed with strong alkaline agents or copper-containing agents, but should be used in turn with other agents.

2. Do not use carbendazim alone for a long time, nor can it be used in rotation with carbendazim, carbendazim, methyl carbendazim and other similar agents. For areas where carbendazim has resistance, the method of increasing drug consumption per unit area should not be used and should be resolutely stopped.

3. It can be mixed with sulfur, mixed amino acid copper zinc manganese magnesium, mancozeb, ammonium mancozeb, thiram, thiophanate zinc, pentachloronitrobenzene, carbendazim, sclerotiorum, bromogeronil, ethyl carbendazim, Jinggangmycin, etc. It can be mixed with sodium sulfonate, mancozeb, chlorothalonil, Wuyistin and so on.

4. Store in a cool and dry place.

The target of carbendazim

1. Control melon powdery mildew, blight, tomato early blight, legume anthracnose, blight, rape sclerotiorum, with 50% wettable powder 100m ~ 200g per mu, spray with water, spray twice at an interval of 5-7 days.

2. Control Botrytis cinerea of onion and leek, spray with 50% wettable powder 300 times, control eggplant and cucumber Sclerotinia sclerotiorum, melon, bean anthracnose, pea powdery mildew, spray with 50% wettable powder 500 times, control cruciferous vegetables, tomato, lettuce, vegetable bean gray mold, tomato, cucumber, bean gray mold, spray with 50% wettable powder 600-800 times.

3. To control Fusarium wilt of tomato, mix seeds according to 0.3-0.5% of seed weight; control bean wilt by mixing seeds with 0.5% of seed weight, or soak seeds with 60-120 times solution for 12-24 hours.

4. To control vegetable seedling blight and quenching disease, 1 part of 50% wettable powder was used and evenly mixed with 1000 Mel 1500 parts of semi-dry fine soil. When sowing, sprinkle the medicinal soil into the sowing ditch and cover the soil, 10-15 kg per square meter.

5. To control Fusarium wilt of cucumber and tomato and Verticillium wilt of eggplant, irrigate the roots with 50% wettable powder 500 times, each plant is 0. 3Lv. 5 kg. The seriously affected plots are irrigated for the second time every 10 days.
