As the most widely used multi-site bactericide , mancozeb, which belongs to the dithiocarbamate in sulfur preparations, under the action of water and air, the agent sprayed on the surface of the plant is converted into EBIS and EBI inhibit the spore germination of pathogens and exert a bactericidal effect.

Compared with the Copper fungicides developed and marketed earlier than Dyson Zinc and Daisen Manganese, the molecular structure of mancozeb is more stable. After spraying on plants, the conversion of EBIS and EBI is more stable and controllable. This has created the advantages of mancozeb on the disease and the safety of crops.

In addition to the characteristics of the mancozebs summarized above, in the production, mancozeb has the following characteristics, and if it is applied reasonably, it will have an unexpected effect.

1, resistant to rain, can be lazy: high quality mancozeb, sprayed on the surface of the plant, the mancozeb particles are small, strong adhesion, in a little dew or rain, twice Distribution, more evenly distributed on the foliage or fruit surface. Therefore, when it is used to control crop fungal diseases in rainy areas or seasons, it is possible to spray before the rain, and it is generally not necessary to make up the spray after the light rain;

2, can be mixed, strong, can save snacks: Mancozeb can be combined with most fungicides or ready-made or ready-to-use, today's production of mancozeb compound preparations or formulations are many Classical fungicide. For example, glacial urea cyanide zinc, oxazolone manganese zinc, enoylmorphomanganese zinc, refined metalaxyl manganese zinc, carbendazim manganese zinc and the like. Mancozeb, mixed with other bactericidal agents, not only expands the bactericidal spectrum, but also improves the bactericidal effect. For farmers with low technical level, there will be fewer choices in the mixing formula and timing of medication. a lot of entanglement;

3, super sterilization, after the disease control tool: the multi-site sterilization effect of mancozeb is unparalleled, sometimes due to the rainy weather or prevention of unfavorable disease caused by the stubborn epidemic, at this time, can increase the mancozeb moderately Dose, carefully sprayed, often has unexpected effects. But the premise is that the quality of the mancozeb you choose must be excellent, otherwise the risk of phytotoxicity will be high.

4, disease prevention nutrition double effect, one arrow double carving: Spraying mancozeb during crop growth can not only sterilize and prevent disease, zinc and manganese contained in the medicine can also be used as nutrients to promote crop growth. For example, cowpeas in the rainy season, because of the appropriate temperature and humidity, the growth of cowpeas is strong, and the spectacular scenery of the long beans like the curtains is the best reward for the hard work of the farmers, but the high temperature and high humidity are also prone to cowpea rust and brown spot. And other fungal diseases. It is not conducive to photosynthesis. Zinc is beneficial to the development of young shoots and young leaves. Manganese is an indispensable element for photosynthesis in leaves. Kidney beans that grow rapidly in the rainy season need to be supplemented with sufficient zinc and manganese. The use of mancozeb can be satisfied at the same time. These two different growth needs of cowpea. Therefore, in the rainy season, every day, 7 to 10 days, the mancozeb is played once, and even three times, the leaves of the cowpea are bright green, and the quality and yield of the beans are very good.
