Carbendazim has many advantages such as wide bactericidal spectrum, obvious efficacy and long drug efficacy period. It is an ideal bactericide. However, in the production practice, some farmers have had some problems due to lack of knowledge about the use of drugs. To this end, the author recently visited Xie Yuwei, a mushroom cultivation expert in Zhouying Township, Shenqiu County, and introduced to him the four issues that he mentioned when using carbendazim.
First, the market for carbendazim is mostly 50% wettable powder and 40% suspension. Regardless of the type of dosage, high-quality products should be used. The effective period of the product should also be taken into consideration. The production date should be within one year. If the dosage exceeds this limit, the dosage should be increased as appropriate.
Second, carbendazim on Mucor, Rhizopus control effect is poor, when using carbendazim should be properly raised the pH of the culture material to inhibit the growth of Mucor, Rhizopus. Due to the high temperature resistance of carbendazim, it is best to use culture materials for fermentation and high temperature sterilization to kill molds. Tremella, fungus, and Hericium are particularly sensitive to carbendazim and should be avoided.
Third, the use of carbendazim spices, should strictly control the concentration of liquid, generally with a content of 50% of the powder, to account for 0.1% of the dry weight of the material can kill and inhibit the growth of bacteria; if you increase the dosage, not only Increased costs will also affect mycelial growth, leading to contamination of fruiting bodies. When mixing materials, first dissolve the chemicals into a sufficient amount of water and mix them evenly, and mix them evenly after mixing in order to prevent spot contamination.
4. Carbendazim is easily decomposed and deactivated in an alkaline environment. Therefore, it is not possible to use lime at the same time in the seasoning, and it is impossible to use carbendazim and lime mixture for a long time. In addition, carbendazim is resistant to bacterial growth, so long-term use should be avoided, and other fungicides can be used interchangeably.
