Configuration and use of soil pesticides

When artificially producing pollution-free soil pesticides to control vegetable pests and diseases, it is not only low in cost, pollution-free, easy to manufacture, but also harmless to humans and animals. The corpse preparations will be the cabbage caterpillars in the vegetable garden, the wheatworms in the wheat field, the armyworms in the jade field, the tigers in the cotton fields, and the bollworms in the cotton fields. After collecting, they will be smashed into pulp, and 50 ml of water will be added according to 100 grams of worm pulp. After soaking for 24 hours, filter out the insect liquid, then add 50 kg of water and add 50 g of washing powder. Stir well and then form a "medicine solution". If these liquids are sprayed on crops infested by similar pests, the killing rate can reach over 95%. Other different types of pests will also refuse to eat and starve to death. The leaf preparation is smashed with 15 kg of fresh bitter eucalyptus leaves and added with water 15 kg. After filtration, the residue is slag, and 40 kg of water is added per kilogram of juice to control the cabbage worm and the vegetable mites.

Add 1 part of water with 3 parts of skunk leaves, soak for 1-2 days, filter the water immersion liquid and spray it to control a variety of pests such as cabbage caterpillars and aphids. Pigeon manure preparation plus 1 kg of pigeon droppings per 10 kg of water, sealed in a barrel or in a cylinder for about 20 days, stirred evenly during use, and then poured into the roots of melons, which can effectively kill underground pests such as ground tigers. Can play a topdressing role. The grass ash preparation is used for 10 kg of grass ash, soaked in 50 kg of water for 24 hours, and then the filtrate is sprayed, which can effectively prevent the mites, yellow stalks and other hazards; if the onions, garlic and leeks are harmed by the fly, they can apply or spread the ash per mu. 25-30 kg, not only to prevent mites harm, but also to increase potassium production, the effect is very obvious. The wheat bran preparation first sautes 5 kg of wheat bran, cools it for later, and then mixes 90% crystal trichlorfon 130 g, white sugar 250 g, white wine 50 g and 5 kg warm water, and then pours the cooled wheat bran into a good one. The mixture is stirred. In the evening on a sunny day, it can be sprinkled between the rows of vegetables or near the roots of the seedlings (or a pile of a certain distance), which is effective for preventing and killing underground pests such as tigers and cockroaches. Baking soda preparation with 0.2% concentration of baking soda solution (500 grams of baking soda and 50 kg of water), spraying cucumber, cabbage and other vegetables, the control rate of powdery mildew, anthracnose, downy mildew and kidney bean gray mold Up to 95%. Potassium permanganate preparation uses 0.2% potassium permanganate dilution solution to control melons to prevent powdery mildew, spray once every 5-7 days, even spray 2-3 times, the control effect is no less than that of powder rust and other pesticides, and No pollution. Spraying 800 times of potassium permanganate in the eggplant seedling stage can effectively prevent root rot and rickets, and the control effect is as high as 95% or more.
