Product features
① Carbendazim is one of the most commonly used fungicide varieties. In addition to being used as a spray, carbendazim can also be used for seed dressing and root irrigation. It has a certain preventive and therapeutic effect on a variety of fungal diseases, especially soil-borne diseases such as wilt and Verticillium wilt, and has a stimulating effect on the growth of vegetables. If used improperly for a long time, it is easy to induce pathogens to develop drug resistance.
② Carbendazim penetrates into the plant body through plant leaves and seeds, is resistant to rain erosion, and has a long lasting effect. Its conduction and distribution in the plant body are related to the transpiration of the plant. Strong transpiration leads to fast conduction and distribution; weak transpiration leads to slow conduction and distribution; in parts with strong transpiration, such as leaves, the amount of the agent distributed is large; in organs with weak transpiration, such as flowers and fruits, the amount of the agent distributed is small. Under acidic conditions, the water solubility of carbendazim can be increased, and the penetration and conduction capacity of the agent can be improved. After acidification, the mobility of carbendazim through the cuticle on the surface of the plant increases by 4 times compared to when it is not acidified.
③ Carbendazim is often mixed with sulfur powder, triadimefon, tricyclazole, mancozeb, Jinggangmycin, pyrimethanil, flusilazole, procymidone, fosetyl-aluminum, ethotripsy, isoprodinil, bromothionil, tebuconazole, propineb, copper sulfate calcium, thiram, prochloraz, metalaxyl, diniconazole and other fungicide ingredients to produce compound fungicides.
④ Key points for identification: The pure product is white crystals. It is almost insoluble in water, has poor solubility in most organic solvents, is soluble in dilute inorganic and organic acids, and forms corresponding salts. The original drug is a light brown powder and can be stored for two years at room temperature. The wettable powder is a brown loose powder, and the 40% suspension is a light brown viscous and flowable suspension. Check the "three certificates" of pesticides when purchasing; the product should obtain a pesticide production approval certificate.
