Seven plant species can be used to prepare soil pesticides
Garlic stems and leaves: Cut the stems of the garlic stems into small pieces of 6-7 cm and sprinkle them in the early rice fields to make them rot. Allicin contained in garlic can reduce the occurrence of pests and diseases and reduce the number of spraying drugs. If the chopped garlic leaves and stems can be put into the field before ploughing, the time for disease prevention and treatment will be longer and the effect will be better.
Castor leaves: The dried ramie leaves are ground into fine powder, mixed with a certain proportion of soil and mixed with fertilizer to spread to the ground, which can control underground pests such as cockroaches, crickets and tigers. Soaked in 1 kg of ramie leaf powder and water 16-20 kg, infused with a kettle, can cure onions, leeks, garlic, radish, Chinese cabbage, cabbage caterpillar, carnivorous mites and so on. It is also possible to make nettle leaf powder into a liquid, and sprinkle it into a toilet, a pig pen, a pit, etc., and has a significant effect on killing mosquito larvae and maggots.
Pinus massoniana: 5 kg of 5 kg of masson pine and boiled water, sealed and soaked for 2 hours to filter and spray, can control rice leafhopper and rice planthopper. 30 times water immersion solution of pine needle can inhibit the spore germination of potato immune disease.
Arborvitae leaves: crush it, add an equal amount of water, extract the stock solution, and add water twice to spray, which can control cotton aphid and aphids. The cypress leaf 10 times water immersion liquid has a significant effect on the control of wheat rust.
Weeping willow leaves: smash it, add water 3 times soaking for one day or boil for half an hour, filter and spray, can control cabbage caterpillars, mites, mites and so on. 5 times water infusion of willow leaves can inhibit wheat rust.
Mulberry leaves: add 5 times of water, boil the original liquid, add 2 kg of water per 0.5 kg of raw liquid, or spray 10 times of water immersion solution of mulberry leaves to control cotton aphid and red spider. The 15 times water immersion solution of mulberry leaves can inhibit the germination of wheat rust pathogens.
Artemisia argyi fresh grass: chop it, add 10 times of water, cook for half an hour, spray after cooling, can control cotton aphid, red spider, cabbage caterpillar.
The above soil pesticides can be made into a stock solution, diluted with time, and the effect is the same.
