Embodiment 1

[0028] First, nicotine is prepared. Take tobacco tendons, tobacco stems or tobacco leaves, crush them, immerse the crushed powder in water at 50°C, extract, filter and purify, and then concentrate the purified medicine to make nicotine. Next, prepare theaculin. Take the tea cake, crush it, immerse the powder in water at 30-50°C, boil the water, extract it, filter it and purify it, and then concentrate the purified medicine to make theakurin. After the preparation of nicotine and theaculin, take 3.125 kg of 2.5% tomatine, 12.5 kg of 10% nicotine, 25 kg of 20% theaculin, and 12.5 kg of 10% polyoxyethylene castor oil emulsifier , 46.875 kilograms of 37.5% turpentine solvent, with its mixing. Then blend the above mixed solution with water to treat powdery mildew, rust, gibberellic, smut and aphids, cotton bollworm, cabbage caterpillar, cabbage butterfly, pine caterpillar, American white moth, armyworm, leaf tortrix, leaf miner moth, apple borer and other pests and diseases.

Embodiment 2

[0030] First, nicotine is prepared. Take tobacco tendons, tobacco stems or tobacco leaves, crush them, immerse the crushed powder in water at 50°C, extract, filter and purify, and then concentrate the purified medicine to make nicotine. Next, prepare theaculin. Take the tea cake, crush it, immerse the powder in water at 30-50°C, boil the water, extract it, filter it and purify it, and then concentrate the purified medicine to make theakurin. After the preparation of nicotine and theaculin, take 7 kg of 10% tomatine, 10.5 kg of 15% nicotine, 24.5 kg of 35% theaculin, and 17.5 kg of 25% polyoxyethylene castor oil emulsifier , 40.5 kilograms of 57.5% turpentine solvent, with its mixing. Then blend the above mixed solution with water to treat powdery mildew, rust, gibberellic, smut and aphids, cotton bollworm, cabbage caterpillar, cabbage butterfly, pine caterpillar, American white moth, armyworm, leaf tortrix, leaf miner moth, apple borer and other pests and diseases.

Abstract

A biological insecticiding bactericide for cucumber, egg plant, hot pepper, etc contains tomatin (2.5-10 wt.%), nicotine (10-15), polyoxyvinyl castor oil emulsion (10-25), turpentine (37.5-57.5), etc. Its advantage is no environmental pollution.

Description

Technical field: [0001] The invention belongs to a pesticide, which is a pollution-free pesticide made from organic matter extracted from plants. Background technique: [0002] There are generally two major problems with the pesticides currently used. One is to kill diseases and insect pests while causing harm to humans, livestock, crops and other non-target organisms. According to the latest data, 20 million people in the world are poisoned by pesticides every year, of which 200,000 The second is that pests and germs develop resistance to pesticides, which speeds up the renewal cycle of pesticides or causes the abuse of pesticides. According to statistics, with the abuse of pesticides, so far more than 500 kinds of pests and hundreds of crop diseases have developed resistance to organic chemical insecticides and fungicides. Since the 1960s, nearly 100 kinds of chemical fungicides developed at home and abroad, 60% of them have been eliminated due to the greatly enhanced res...
