It is understood that the drug has good safety for rice, and it is safe to use rice at the low age of rice, and it is also safe for rice. Generally, it can use 20 grams per acre in the 2-leaf 1 heart stage of rice; it has 1 heart in 3 leaves of rice. During the period, 30 grams per mu can be used; 40-50 grams per mu can be used after the 4-leaf stage of rice until jointing.
Can A 2 Cl 4 be used in the 2-leaf stage of rice?
Rice and other grass crops are sensitive to 2A and 4 chlorine before the 3rd leaf stage. Improper use may cause phytotoxicity to crops, heart defects and other symptoms. After 4th leaf stage, the tolerance to 2A and 4C as leaf age increases. The drug properties also gradually increased, with the strongest drug resistance during the period of childbirth, and the sensitivity increased gradually after jointing. Therefore, it is generally required to apply 2A and 4Cl in the rice from the 4th leaf stage to the jointing stage, and the dosage should not be arbitrarily increased to ensure the safety of rice.
