Seven kinds of plants that can make soil pesticides

Mulberry leaves: add water 5 times, boil it into the original solution, add 2 kg water every 0.5 kg, or spray mulberry leaves 10 times water extract, which can control cotton aphids and red spiders. The 15-fold water extract of mulberry leaves could inhibit the germination of summer spores of wheat rust.

Garlic stems and leaves: cut the leaves and stems of garlic into 6ml / 7cm segments and sprinkle them on the early rice fields to let them rot. Garlic contains allicin, which can reduce the occurrence of diseases and insect pests and reduce the number of spraying. If the chopped garlic leaf stem can be put into the field before ploughing, the time for disease prevention and insect control is longer and the effect is better.

Castor leaves: grind the dry hemp leaves into fine powder, mix them into the soil and spread them into the ground according to a certain proportion, which can control underground pests such as grubs, mole crickets and ground tigers. Soak in 1kg castor leaf powder and 16Mel 20kg of water and pour it in a kettle to cure the ground maggots of onions, leeks, garlic, radish, cabbage, insectivorous pupae, etc. The castor leaf powder can also be made into Jin liquid and sprinkled to toilets, pigsty, dung pits and other places, which has an obvious effect on killing mosquito larvae and maggots.

Masson pine: 5 kg of Pinus massoniana plus 5 kg of boiled water, closed soaking for 2 hours, filtration and spraying can control rice leafhopper and rice planthopper. The 30-fold water extract of pine needle could inhibit the spore germination of potato immune disease.

Platycladus orientalis leaves: mashed, rubbed with the same amount of water, squeezed out the original liquid, and then sprayed twice as much water, can control cotton aphids and borer. The 10-fold water extract of Platycladus orientalis leaves has a significant effect on the control of wheat rust.

Weeping willow leaves: mash it, soak it for a day or boil for half an hour with 3 times of water, filter and spray it to control cabbage insects, aphids, borer and so on. The 5-fold water extract of willow leaves can inhibit wheat rust.

Artemisia fresh grass: cut it up, add 10 times the water, boil for half an hour, spray after cooling, it can control cotton aphid, red spider and cabbage insect.

All the above soil pesticides can be made into the original solution, which can be diluted with the same effect.
