云南省茉莉花主要虫害防治策略

针对元江县茉莉花虫害日益加重,尤其是茉莉蕾螟,发生规律不清、无防治经验借鉴、花农乱用滥用农药,不仅防治成本高、效果不理想,而且造成农药残留和环境污染的现实问题,针对以上情况,于2004年2月申请成立本课题,意在明确茉莉花害虫的种类,掌握主害虫在元江种植区的分布、危害及发生规律,提出经济、有效、安全的防治技术策略,较好地解决茉莉花生产的难题。防治试验结果表明,对付茉莉花主害虫——茉莉蕾螟,只宜选用高效、低毒、低残留的农药。经过试验筛选认为,天泰(2.100倍液)、爱福丁(24.500倍液)、阿巴丁(1.8000倍液)、阿维茵素(1.8 00倍液)、金福丁(100倍液)等生物农药,是目前防治茉莉蕾螟较为理想的药剂,已在大面积生产运用上发挥了较好的防治效益。防治虫害的施药时间在旁晚8、9点施药,可以显著提高防治效果。
