目的:筛选出防治花生蛴螬高效、低残留药剂。方法:试验小区(面积:15×20㎡)随机区组排列,不设重复。浇灌40%辛硫磷缓释剂,均匀施于花生田地表,每小区50 kg药液;40%柴油.辛硫磷乳油灌墩处理。结果:浇施40%辛硫磷缓释剂20天后防效为40%,30天后为50%,防效高于40%柴油.辛硫磷乳油灌墩处理;且荚果被害率最低(4.36%)。结论:40%辛硫磷缓释剂在蛴螬轻发生年对花生田蛴螬具有较好的防治效果和保果效果,可在生产上大面积推广应用。
Objective: To screen out the effective and low residue pesticides for peanut 蛴 防. Methods: The test plot (area: 15 × 20㎡) is arranged in a random block, without duplication. Watering 40% phoxim sustained release agent, applied evenly to the surface of peanut fields, each district 50 kg liquid; 40% diesel. Phoxim EC filling. Results: The control effect of 40% phoxim was 40% after 20 days and 50% after 30 days. The control efficiency was higher than that of 40% diesel and phoxim irrigation. The pod damage rate was the lowest (4.36% ). CONCLUSION: 40% Phoxim sustained-release agent has good control effect and fruit-preserving effect on peanut shrews in the year of birth, which can be widely applied in production.
