Daejeon grows vegetables, and all kinds of insect pests make people miserable. Didn't try the simplest insecticide material "grasswood ash"? In addition to being a fertilizer, it also has insecticidal efficacy! There are two specific methods:
One is to soak juice to kill insects. First, prepare the wood ash and simply sieve to remove impurities. Then, the ash and water were weighed, and the ash and water were bottled and mixed according to the ratio of 1:1. After soaking for 10 hours, the bottom of the bottle is grass ash and the upper part is ash leaching liquid. Finally, take the upper juice and pour it into a watering can.
The other is dry ash killing bacteria. You can directly sprinkle wood ash on the surface of the soil where the pests and diseases are found, and then use the tools to turn over the soil, remembering that you cannot hurt the roots. Wait a few days to observe the insecticidal effect. It can also be directly applied to the crop leaves to kill pests and germs. The method is to wet the vegetable leaf first, then sprinkle the wood ash on the wet vegetable leaf. Two days later, the ash will be removed, or the ash attached to the leaves will be washed away with water spray.
