Different herbicides are used depending on the soil. Chlorsulfuron-containing herbicides are degraded in the soil mainly by hydrolysis. In the case of alkaline soil, low rainfall in the year of application, and soil drought, the residual period of the field in the soil is often prolonged, and the crops are vulnerable to damage. On the other hand, acidic soil, moist soil or irrigated farmland will have a shorter residue period, and the crop will be relatively safe.
If herbicides containing chlorsulfuron and metsulfuron-methyl have been applied in the previous stubble, such as dicaminin, dicamba, etc., the latter stubble cannot be planted with corn, soybean, cotton, peanut and other crops, nor can it be used as seedlings. In recent years, the use of besulfuron in some places has produced different degrees of pesticide damage to peanut stubble, resulting in difficulty in peanut emergence, slow growth and reduced yield.
Improve methods and reduce drug residues. First, the dosage should be accurate, the spraying should be uniform, and there should be no leakage or re-spraying. For example, the continuous application of herbicides containing chlorsulfuron-methyl will not only cause pesticide damage to the later crops, but also cause pesticide damage to the current crops. Second, the use period should be flexible. It can be used for pre-sowing and pre-emergence soil treatment, and can also be sprayed after seedling. At present, early post-seedling spray should be used for Pusted, Guangfen and atrazine to achieve the purpose of reducing the dosage and reducing the residue. The third is reasonable pesticide application. Strip spraying with Pust and Guangxing can reduce the dosage by more than 30%.
To avoid affecting the crops, herbicides should be used in this way to introduce here, I hope it will help you. If you want to buy high-quality and high-yield vegetable seeds, you can download the seed bank App, and the country's excellent vegetable varieties are available for everyone to choose.
