本文报道了混配剂丰保磷(SIP-9001)对甘蔗黑色蔗龟的室内毒力测定和在大田对甘蔗主要害虫的药效试验结果。室内毒力测定,混配剂丰保磷的共毒系数(CTC)为297.5。将混配剂制成3%颗粒剂进行大田药效试验,对黑色蔗龟成虫引起的枯心苗、二点褐鳃金龟幼虫引起的死苗、齿缘鳃金龟幼虫、甘蔗螟虫枯心以及蓟马的防治效果平均分别达到83.6、98.6、80.6、59.6和92.7%。在大田表证示范中,水田蔗区和旱地蔗区分别用3%丰保磷颗粒剂5和6kg/亩,结果:示范区甘蔗枯心苗平均比同剂量对照药呋喃丹分别减少51.0和6.9%;示范区甘蔗产量比同剂量呋喃丹相对增产10.1-42.3%。
In this paper, we report the indoor toxicity test of the compound PEG-SIP-9001 against sugarcane black sugarcane and the results of the efficacy test on the main sugarcane in the field. Laboratory tests showed that the co-toxicity coefficient (CTC) of the compounded PFT was 297.5. The mixed agent made of 3% granules for field efficacy test, black cotyledon adult caused by the dead heart seedlings, two brown gill beetle larvae caused by dead seedlings, gill beetle larvae, cane stem borers and heart thistle The average control effect of horses reached 83.6, 98.6, 80.6, 59.6 and 92.7% respectively. In the field demonstration, paddy field and dry land were 3% FenPao Granules 5 and 6kg / mu, respectively. Results: Compared with the same dose of carbofuran, the average dry weight of sugarcane in the demonstration area decreased by 51.0% And 6.9% respectively. The yield of sugarcane in the demonstration area was 10.1-42.3% more than that of the same amount of carbofuran.
