Guo Shize from Guantan Town, Pixian County, said on June 18th that his 3 mou dry direct seeded rice was soaked with 100 ml of 960 g/l metolachlor EC per acre on the second day after sowing. There was no irrigation after spraying. He asked whether rice would be harmed by metolachlor and how to remedy it.

It is understood that metolachlor is a chloroacetamide herbicide and is an efficient, broad-spectrum, selective pre-emergence herbicide for soil treatment. It is mainly used in drylands such as soybeans, corn, cotton, peanuts, potatoes, and cabbage. Crop fields control annual grass weeds and some broadleaf weeds. The drug is mainly absorbed by young shoots of plants. The monocotyledonous weeds are mainly absorbed by the coleoptile, and the dicotyledons are absorbed by the young shoots and larva roots and are transmitted upward to inhibit the growth of young shoots and roots. The sensitive weeds are unearthed after germination or Poisoning died just after exhumation. The grass leaves of grasses are distorted and atrophied, and other leaves are shriveled and the entire plant is withered. As the ability of weed grass weeds to absorb drugs is stronger than that of broad-leaved weeds, the effect of controlling grass weeds is better than that of broadleaf weeds. The drug should not be used in paddy fields and direct seeding fields, and it should not be used to increase the dosage.

Metolachlor has a very high activity in paddy fields. At present, Metolachlor has been successfully used in rice transplanting and transplanting fields to control weeds. However, young rice is sensitive to the drug and it is easy to produce phytotoxicity after application. Jiangsu Changlong Chemical Co., Ltd. 70% metolachlor EC is registered for the control of annual weeds in rice transplanting fields. The recommended dosage per hectare is 105.5 to 210 grams, equivalent to 10 to 20 grams of mu preparation, and toxic soil. Application of pesticides.

The person in charge of Syngenta Crop Protection Co., Ltd. said in an interview with related reporters that in general, 960 g/l of metolachlor emulsion per acre in dry direct broadcast rice fields will cause phytotoxicity to rice; If the amount of pesticide used per acre exceeds 20 grams in the planted fields, rice seedlings will show phytotoxicity. According to Guo Shize, 100 grams of 960 g/l metolachlor is used per acre in paddy rice fields with dry direct seeding, and the amount of medicine used is very large, and rice will be seriously poisoned. Due to the large amount of pesticides used in the above fields, the maximum amount of rice that can be transplanted has been exceeded, and the residual period of metolachlor in the soil is more than 45 days. No good measures can be taken to remedy the situation. Replant corn, soybeans and other dry crops.
