Description
技术领域
本发明属于杀虫剂技术领域,涉及一种木醋液根结线虫杀虫剂。
背景技术
木醋液是农林废弃物采用干馏热解工艺后的气体经冷凝分离得到的红褐色液体组分,具有特殊的烟熏气味,呈酸性。含有200多种成分,包括酸类、酚类、醛类、酮类、醇类和酯类等有机化合物。有报道公开过木醋液在农业防虫抑菌方面的用途。
根结线虫是一种高度专化型的杂食性植物病原线虫,主要危害各种蔬菜的根部,表现为侧根和须根较正常增多,并在幼根的须根上形成球形或圆锥形大小不等的白色根瘤,有的呈念珠状。被害株地上部生长矮小、缓慢、叶色异常,结果少,产量低,甚至造成植株提早死亡。
发明内容
针对上述技术问题,本发明的发明人经过创造性的劳动,研发了一种木醋液根结线虫杀虫剂。
为实现上述目的,本发明所采用的技术方案是:
一种木醋液根结线虫杀虫剂,添加了木醋液,其他原料按重量份数比为:蛇床子30~40份,黄荆30~40份,大黄10~15份,艾蒿10~15份,石榴皮10~15份,黄柏10~15份。
其中,各原料组分优选为:蛇床子35份,黄荆35份,大黄12份,艾蒿12份,石榴皮12份,黄柏12份。
制备上述木醋液根结线虫杀虫剂,包括以下步骤:
(1)将蛇床、黄荆、大黄、艾蒿、石榴皮、黄柏粉碎至20目,加入重量5倍的水,煮沸3小时;滤去药渣,再在药渣中加入重量3倍的水,煮沸2小时,重复一次;合并药液,按药液重量的2%加入木醋液;
(2)将药液蒸发、浓缩,制得浸膏粉;
(3)将浸膏粉按2:1的重量比加入浓度70%的乙醇,搅拌均匀;
(4)将水、吐温80、松节油按重量比100:1.2:1.5在反应釜混合,再加入乙醇浸膏混合物,使浸膏粉的重量达到溶液总重量的4%,混合乳化2h,即得。
使用时,木醋液根结线虫杀虫剂稀释20~30倍,可用于根结线虫的杀灭。
通过以上技术方案,本发明的有益效果如下:
本发明使用的原料含有多种可杀灭根结线虫的生物活性成分,药材安全、稳定、有效、可控,不会产生抗药性,具有分解快、残留低、污染少等特点不会对生物链产生阻断影响,稀释液对作物、人畜无害。
