精噁唑禾草灵6.9%水乳剂防治烟地杂草药效试验

Trial on the Efficacy of Fenoxaprop-P-ethyl 6.9% EW on Controlling Weeds in Tobacco Field

试验结果表明,精噁唑禾草灵6.9%EW1200,1500mL/hm2对禾本科杂草有明显的除草效果,其除草、保产效果明显优于精噁唑禾草灵6.9%EW600、900mL/hm2,稍高于乙草胺50%EC3000mL/hm2,是一种较理想的烟田除草剂。建议使用剂量为精噁唑禾草灵6.9%EW1200、1500mL/hm2和乙草胺50%EC3000mL/hm2,可推广应用。

The results showed that fenoxaprop-P-ethyl 6.9% EW 1200, 1 500 mL/hm^2 had very good effect on controlling the gramineae weeds in tobacco field, the weeds control efficacy and keep-stable-yield effect were better than that of the fenoxaprop-P-ethyl 6.9% EW at 600, 900 rnL/hm^2, and they were a little better than that of acetochlor 50% EC at 3 000 mL/hm^2. The fenoxaprop-P-ethyl 6.9% EW is a good herbicide for tobacco field. It can be extended in use for fenoxaprop-P-ethyl 6.9% EW at 1200, 1 500 mL/hm^2, and for acetochlor 50% EC at 3 000 mL/hm^2.
