Quick killing of bismuth (quinclorac): In the 300 days after the application of fast killing, no crops can be planted except for rice. Eggplant and tobacco cannot be planted within 12 months, and tomatoes and carrots cannot be planted within 2 years. In addition, umbelliferous crops such as carrots, celery, and cilantro are very sensitive to fast killing, and it is not possible to water the above crops with the water of the paddy fields that have been killed.
Chlorsulfuron-methyl: It has a long retention period in the soil, and it is not suitable to grow beets, rice, potatoes, melons, vegetables, sorghum and cotton.

Sike (Metazine, oxalofenone): According to the experiment, the active ingredient of 420-1120 g per hectare (15 mu) can be used to grow alfalfa, asparagus, wheat, barley, corn and potato after 4 months. Sweet potatoes, sugar cane, soybeans, grasses and pastures; rice and cotton can be planted after 8 months, and other crops other than roots can be planted for 12 months. At present, it is generally recommended that the dosage of Sike is 210-560 grams per hectare of active ingredient, which is generally safe for the crop after harvest.

Guanglingling: It is reported that per turf (15 mu) can be planted with rice, cotton, corn, pepper, tobacco and cucurbit crops for 9 months after application of 560-1400 g of active ingredient; 16 months later All crops can be grown. At present, it is generally recommended that the amount of chlorhexidine used in combination with other drugs has no effect on the sorghum crop, but heavy spray has a slight effect on wheat.
