Inquiries: The herbicide used in this year's corn field is acetanilide. Can we plant other crops next year?
Answer: First, the characteristics of Atrazine. 1. Atrazine is a selective pre-emergence and post-emergence herbicide. In corn and other resistant crops, it is decomposed by zeaxanthene to form non-toxic substances, and therefore safe to corn and so on. 2. Atrazine is water-soluble, and the residual period is affected by the dose of the drug, soil texture, etc. It can be as long as about six months. 3. Atrazine is effective for a long period of time and it is easy to cause damage to sensitive crops such as soybeans, rice, beets, rapeseed, flax, watermelon, melon, wheat, barley, and vegetables.
Second, why the use of Acetonitrile, A, B herbicides will produce phytotoxicity on the next crop. 1. Acetoin is a combination of acetochlor and atrazine. Acetochlor is a combination of acetochlor, alachlor and atrazine. After compounding, the spectrum of herbicides is increased. Due to the presence of atrazine in the compounding agent, improper selection of the next crop can easily cause injury. 2. The dosage of the herbicide is arbitrarily increased, so that the atrazine content and the residual period in the soil are prolonged, causing damage to the crop. 3. Do not understand the herbicide properties mainly used in corn fields. The main crops that reflect more crops include beans, cotton, and sunflower.
Third, planting suggestions. 1. Crops and vegetables planting areas, food crops and cash crops planting areas. Corn fields are suitable for the treatment of soil with acetochlor prior to broadcast. Spraying with tribenuron, 2.4 D butyl ester and other herbicides with a short residual period of time. 2. Do not arbitrarily increase the amount of herbicide. 3. If herbicides are used in corn fields this year, the number of herbicides used must be ascertained. If B is used as a combination of B and A, it is necessary to rationally arrange the cultivation of the next crop.
