Both wheatgrass and thrips are herbicides commonly used in agriculture. Here's how to mix them:
The main components of Mai Cao Ning are chlorsulfuron-methyl and metsulfuron-methyl. These two pesticides are all sulfonylurea herbicides. When used in combination with thrips, they produce sputum effect and reduce the control effect of thrips. Separate the thrips from them and use them at intervals of 7 to 10 days. In addition, the residual effect period of chlorsulfuron-methyl and metsulfuron-methyl is very long, and it is only relatively safe to use on the acidic soil of the wheat-rice rotation in the Yangtze River basin, otherwise it will easily cause residual phytotoxicity of the crop. The soil in the wheat field of Yizheng and other fields is generally acidic, and the application of these two drugs in the wheat field at normal doses will not cause much harm to the transplanted rice after the transplanting. The sorghum is the direct seed rice or the rice seedling, and the wheat field cannot be applied. A kind of medicine, otherwise it is easy to cause phytotoxicity to rice, which is generally characterized by yellowing of leaves at the seedling stage and growth inhibition. In the case where the application amount of the two drugs is too large, the phytotoxicity will be further aggravated, causing the dead seedlings to not be born or even dead. At present, chlorsulfuron and metsulfuron have been banned in our province, and it is recommended not to apply these drugs in wheat fields.
The above is the introduction of the mixed use of wheat grass and hummer. For more information on pesticide encyclopedia, please visit China Pesticide Network.
