How to treat rice damaged by metsulfuron-methyl herbicide injury?

Remedial measures: After transplanting (or throwing) seedlings in fields where herbicides have been applied, field inspections should be strengthened. When herbicide injury occurs, measures must be taken immediately to reduce losses. 1. Re-transplant (re-throw) seedlings: If diagnosis confirms severe seedling injury, with more than 80% of seedlings yellowed and some withered, seedlings must be gathered for immediate re-transplanting (re-throwing). Method: First drain the field water, lightly harrow once, then drain the muddy water, then level the field and transplant (throw) seedlings. In recent years, sowing and transplanting (throwing) seasons have been advanced by 7-15 days compared to traditional seasons. From discovery of injury to re-transplanting is generally 5-10 days, so the seasonal conflict is not prominent. 2. Strengthen fertilizer and water management and intertillage: For fields where injury is found, first drain the field water that has been treated with herbicide and irrigate with fresh flowing water. Next, perform intertillage to break up the original herbicide liquid layer and turn the herbicide adsorbed by the surface soil into deeper soil, reducing the effect of the herbicide on rice roots. 2-3 days after intertillage, apply 2-4 kg of imported compound fertilizer per mu to promote root growth and leaf development and accelerate growth. 3. Apply rooting agent: After draining, intertilling and fertilizing, it is best to apply 200 kg per mu of rooting agent ABT at a concentration of 200 mg/kg, which has a good effect on promoting roots. The number of roots can increase by 25%-40%, growth speed accelerates, and the sufficient seedling stage is delayed by only 5-7 days.
