1999~2003年连续的试验、示范及大面积应用表明,锐劲特是防治稻纵卷叶螟的优秀杀虫剂之一。在稻纵卷叶螟低龄期使用450~600毫升/公顷,药后3天杀虫效果在77.52%~89.35%,药后7天杀虫效果在88.6%~100%;在水稻生育中后期使用,对稻纵卷叶螟的防效较生育前期效果稳定,防效略优且持效期更长;同时锐劲特对水稻其他主要害虫如二化螟等防效也十分突出,在水稻多靶标害虫的总体防治中,具有较高的推广价值。
From 1999 to 2003, the continuous experiments, demonstrations and large-area applications indicated that Regent was one of the best insecticides for controlling rice leaf roller. 450 to 600 ml / ha was used at the lower stage of the rice leaf roller, the insecticidal effect was 77.52% ~ 89.35% after 3 days and the insecticidal effect was 88.6% ~ 100% within 7 days after the medicine was applied; , The control effect of the rice leaf roller is stable than the pre-breeding period, slightly superior control effect and longer duration; the same time, sharp sharp special rice other pests such as Chilo suppressalis also very prominent control effect in the rice and more The target pest in the overall prevention and control, has a higher promotional value.
