The invention relates to a green pollution-free pesticide and a preparation method thereof. The utility model is characterized in that the whole herb extract of bitter kudzu is 78 to 98%, and the sugar is mixed with sugar from 1 to 22%. After soaking the fresh or dry products of the whole plant of bitter Pueraria, beating, repeatedly squeezing the juice for 3 to 4 times, filtering, removing the starch from the filtrate, concentrating and extracting the extract of pueraria. The invention of green pollution-free pesticides can kill the underground black bug (during the day in the evening, in the stems and leaves of plants, commonly known as the tiger), grub, earthworm, leech, red water insects and invisible insects, plants, aphids and caterpillar on plant disease, white rust downy and mites (red spider, rust, wind wall scale) and has good control effect and killing effect, have certain killing effect for any ground seedbed seedlings devour pests. The wide spectrum of insect killing, and because the plant itself is alkaline, a solution is not in disguise, plant residues, soil structure destruction will not cause pollution to the environment and beneficial insects.
【技术实现步骤摘要】
本专利技术涉及农药
,具体地说是绿色无公害农药及其制备方法。
技术介绍
现有的农药种类比较多,但大多是化学合成的。虽然杀虫效果较好,但不尽人意的是农药残留,对人畜的健康有不良影响。
技术实现思路
本专利技术的目的是提供一种纯植物提取制备的,对人畜无害的,杀虫效果突出的绿色无公害农药及其制备方法。本专利技术的技术方案为用苦葛[pueraia.Peduncularis(Berth.)Grad.]全草提取液78~98%,白糖1~22%混合而得。上述的绿色无公害农药的制备方法按以下步聚进行1)将苦葛全草的鲜品或干品浸泡后,打浆,反复榨汁3~4次,过滤,滤液静置除去淀粉,浓缩后得苦葛提取液备用;2)将1)所得的苦葛提取液78~98%和白糖1~22%混合后,加入0.1~0.5%防腐剂得到绿色无公害农药。苦葛制备提取液后的滤渣用于防虫纸原料和作为农肥。本专利技术的绿色无公害农药还可以按以下方法制取将苦葛全草锤成绒状物晒干,打成粉末,过60目以上筛制成粉剂,用10~20%的苦葛粉剂与钙肥或镁肥或磷肥或钾肥或复合肥等肥料混合后,制得施入地下的肥药两用农药。本专利技术的绿色无公害农药可以杀死地下的黑虫(白天在地里,晚上在植物的茎叶上,俗称地老虎)、土蚕、蚯蚓,水里的蚂蝗、小红虫及肉眼看不见的虫,植株上的菜青虫、蚜虫以及对植物白粉病、锈病、霜霉病和螨类(红蜘蛛、锈壁风、蚧壳虫)等都均有较好的防治效果和杀灭效果,对于任何苗床地里吞食幼苗的害虫都有杀灭作用。其杀虫虫谱较宽,又由于植物本身有碱性,较易容解,故不会在植物上残留,不会破坏土壤结构,不会对益虫及环境造成污染。本专利技术的农药 ...
