果树注入法治虫技术注入法常用于防治果树害虫。选用内吸性杀虫剂，用针筒或滴管将药液注入树皮内的韧皮部，通过传导，将药液分布于树体，以控制一些刺吸式口器的害虫。这种方法防效高，施用简便，药效持久，不受地形、树体高度和气候条件的限制，对天敌影响小，不受水源影响。具体措施如下：1．选择农药选用内吸性强的农药。目前治虫效果好的内吸性农药有：40%氧化乐果、40%乐果、25%杀虫双水剂、25%杀虫脒水剂、75%可湿性呋喃丹等。2．注入时期从春季果树树液开始流动至秋季果树进入休眠期前的一段时间均可，4月-8月为最佳时期。3．注射药量按树体的大小而定。树高2.5米、冠径2.3米、干粗9厘米-13厘米的树，每株注射原液1.5毫升-2.5毫升；幼树注射1毫升-1.5毫升；成年大树可适量增加，以3毫升-5毫升为宜。4．注入方法用钻在树干离地面20厘米处，向下倾斜45度左右，四周打3个-5个孔，后用滴管或注射器将药液缓缓注入即可5．治虫效果注药后3-4天害虫即大量死亡，6-7天全部死亡。打孔伤口两个月左右可愈合。6．注意事项（1）注意人畜安全。（2）夏季高温季节应将原液稀释3-6倍，分次注射。（3）氧化乐果对蜜蜂毒性较强，花期不宜使用。（4）在采果前40天不用药，以防污染水果。(源自:中国林业网)
