Plant Protection(2023)
Abstract
以常规化学农药防治为对照,研究了柑橘病虫害"八字诀(剪、肥、放、疏、草、诱、捕、治)"绿色防控模式的田间应用效果.结果表明,"八字诀"模式对柑橘叶螨的有效控制时间在180 d以上;对潜叶蛾、锈壁虱的防控效果持效性显著优于化学农药对照;对蚜虫、叶甲、柑橘粉虱的防控效果与常规化学农药防治无显著差异;频振式杀虫灯主要诱杀吸果夜蛾、斜纹夜蛾、凤蝶等鳞翅目害虫,其次是半翅目害虫.对疮痂病和黑点病两种重要病害的防效均极显著优于常规化学防治对照."八字诀"模式应用后柑橘的产值高、成本低,平均用药量从15 750 g/hm2减少到9 375 g/hm2,节本增效 11 700 元/hm2.
