You don't need to spray pesticides to grow vegetables? Some people's homemade insecticides are more effective, so you can rest assured if you eat them yourself.

People who have grown vegetables know that as long as they grow vegetables, there will be all kinds of pests, of which green insects of leafy vegetables are the most harmful, whitefly of eggplant and fruit annoys many vegetable farmers, and root maggots of leeks and other underground pests are particularly difficult to control. Generally speaking, the insects on vegetables are very difficult to treat, and vegetable farmers will spray more and more medicine over and over again, which is more and more toxic, and the harm to the human body is also very serious.

In fact, the efficacy of some homemade pesticides is not poor at all. The reason why they are used less is that, on the one hand, people are relatively lazy, and self-made pesticides are not as direct and convenient as direct use of pesticides. Second, many people are still superstitious about pesticides. They always feel that spraying pesticides is effective. In fact, this is not the case. At least I have tried the following methods, and the results are still good.

1. Plant ash liquid to control insects. Plant ash is really a good thing, not only can be used as fertilizer to improve the soil, but also a very good agent, the filtrate can control aphids, the formula is: plant ash 10 kg to 50 kg of water soak for 24 hours. Root application has a good effect on maggots, which can be applied to the roots of scallions, leeks and garlic. the specific method is to apply or spread 20 kilograms of plant ash per mu to cure maggots and increase production.

When spraying urine washing mixture, you must pay attention to the full dissolution of urea before spraying, otherwise you may burn vegetable leaves.

In this way, there is no need to fill the root with liquid medicine, nor to take other preventive measures. The radish not only does not give birth to ground maggots, but also has a smooth skin and is resistant to storage.

The above methods are all good. If you are interested, you can try them, or if you have any good ways to kill insects, let's discuss them together.
