Acetochlor, also known as ethyl acetochlor, vesace, and oxacillin, is a selective pre-emergence herbicide and is an amide herbicide. Acetochlor can be absorbed by plant sprouts, interfere with nucleic acid metabolism and protein synthesis in plants, and stop the growth of young shoots and young roots. After the herbaceous weeds were damaged, the new leaves curled and shrank, the other leaves shrunk, and the whole plant died. Gramineous plants mainly absorb the agent through the bud sheath. Therefore, the herb should be applied before the weeds are unearthed, and the soil is closed, otherwise the control effect is not good. Cucumber, rice, spinach, wheat, leeks, millet, sorghum and other crops are sensitive to acetochlor. It is not advisable to use this medicine.
Can rice be riddled with acetochlor after using acetochlor? It is understood that Nai'an has detoxification effects on various herbicides such as sulfonylureas and amides, but it is generally required to be mixed with related herbicides, or it may be used alone in advance in the presence of herbicide residues in the soil for prevention. After the rice blast was tainted by acetochlor, it was effective to use Nian's rescue. We did not get a clear reply from the relevant departments. Considering that even if the seedlings are gradually restored to growth, their growth potential is relatively weak, and the rice breeding season is very tight. It is recommended to replant the seedlings as early as possible to avoid mistakes in farming time.
The soil has strong adsorption to acetochlor, and acetochlor has less leakage after being applied to farmland. The half-life of acetochlor in the soil is 8-18 days. Misuse of acetochlor in the field, replanting and rearing after ploughing still has certain risks, it is best to change the field. These fields can be used to sow bean crops after ploughing. If the amount of acetochlor is not very large, it is also possible to transplant rice after ploughing (currently part of the acetochlor compound is registered for rice transplanting, and it is required to be applied after rice transplanting). Spraying Nian and other antidote to the seedlings before transplanting may be more beneficial to the phytotoxicity of the rice seedlings.
