Methyldisulfuron is a widely used herbicide that is mainly used to control weeds in wheat fields. The size of its dosage per mu is crucial for the weeding effect and crop safety. This article will introduce the dosage of methyldisulfuron-methyl per mu in detail to help readers better grasp its use methods and precautions.
First of all, let's understand the mechanism of action and scope of application of methyldisulfuron. Methyldisulfuron mainly achieves the purpose of weeding by inhibiting the photosynthesis of weeds, and has a good control effect on a variety of annual and perennial weeds. It is suitable for field weeding of gramineous crops such as wheat, barley, oats, etc.
So, what is the dosage per mu of methyldisulfuron-methyl? This needs to be determined according to the specific crop and weed species. Generally speaking, the dosage per mu of methyldisulfuron is 1between 5-3 grams. For different crops and weeds, the amount per mu may be adjusted. When using, it is recommended to use according to the recommended dosage on the pesticide instructions to ensure the weeding effect and crop safety.
In addition to the dosage per mu, the use of methyldisulfuron also needs to be noted. In general, methyldisulfuron-methyl can be sprayed at the 3-5 leaf stage of weeds. When spraying, it should be sprayed evenly to avoid missed spraying and respraying. At the same time, it is necessary to pay attention to the weather conditions and avoid spraying before and after strong winds or rainfall, so as not to affect the efficacy of the drug.
There are also a few caveats to note when using methyldisulfuron. First of all, methyldisulfuron-methyl is highly selective to crops and weeds, and it is necessary to carefully identify the types of crops and weeds when using them to avoid misuse. Secondly, methyldisulfuron has a certain risk of pollution to soil and water sources, and attention needs to be paid to prevent pollution after use. In addition, the use of methyldisulfuron also needs to comply with relevant laws and regulations and pesticide use regulations to ensure safe and compliant use.
In conclusion, methyldisulfuron-methyl is an important herbicide, and its dosage per mu needs to be determined according to specific crop and weed species. When using, you need to pay attention to the use method and precautions to ensure the weeding effect and crop safety. At the same time, it is also necessary to pay attention to the impact of methyldisulfuron on the environment and ecology, and take active measures to reduce pollution and risks. It is hoped that this article can help readers better understand the dosage and usage methods of methyldisulfuron-methyl per mu, and provide a useful reference for agricultural production.
