| 摘 要： | 研究44%谷友(单嘧.扑灭)可湿性粉剂对谷田阔叶杂草的田间防治效果。结果表明:该药剂使用剂量1800 g/hm2时,施药后30 d防效为95.04%,施药后45 d防效为89.41%,防效高于对照药剂(50%扑灭津可湿性粉剂)。经过对谷子的安全性测定,该剂量对谷苗前期虽有抑制作用,但起到了蹲苗作用,中后期抑制作用趋于消失。该剂量下谷子产量与空白对照的差异较小。 |

| Abstract: | Field controlling effect of 44% Guyou （Danmi- Pumie ） WP on broad-leaf weeds was studied in the paper. The results showed that the control effect was 95.04% with 1 800 g/hm2 of the herbicide after 30 days treatment ,and that was 89.41% after 45 days treatment ,the control effect was higher than the control herbicide （50% Propazine WP ）. Security detection showed that the dosage of 44% Guyou （Danmi. Pumie ） WP slightly inhibited the growth of millet in the prophase, but played a role of hardening seedling, at later stages, the inhibition gradually reduced or completely disappeared, yield had no significantly difference with blank control at the dosage. |
