| Abstract |
To control the residual damage of persistent Sulfonylureas to summer crops, this papermed at the speciality of persistent Sulfnnylureas, researched the control technology by reducing herbicide dosage, accelerating decomposition, debasing crop sensitivity. Adding adjuvants could reduce the dosage, SDP 15 g/hm2, metsulfuron-methyl 7.5 g/hm2, the weed control efect on fresh weight is 93.60%, increased 20% than none adjuvant; mixing with other herbicides, such as MCPA,tribenuron, thiameturon-methy, isoprovuron, etc. Proper agriculture measure, include proper planting density of wheat, using the variety with strong tilering ability, can control the weeds in the field and late spring emergence weeds efectively. The measure of accelerating decomposition of the herbicide, includes using the herbicides in early period, 1-3 leavers of winter wheat, could improve the control effect and reduce dosage, also lengthen the degradation time of the herbicide; increase times of irrigation or irrigating late, can accelerate the drenching and dissolving of the herbicides in the soil; using NA to dress seed and gibberelin or brassinolide after shooting could debase the damage. |
