Grass ash is a very good thing, how to use it to make pesticides?

Vegetable friends who have a certain amount of experience in growing vegetables at home will basically understand that plant ash is a good farm fertilizer, and more precisely, it is a good potash fertilizer.

Of course, you may also know that it can also be used as an insecticide to control some pests, such as aphids, cabbage worms, root maggots, etc.

Most vegetable lovers know that the method may be to mix it directly into the soil to make organic fertilizer or sprinkle it into the soil to control pests and diseases.

In fact, it can also be made into foliar fertilizer or liquid green insecticide, sprayed directly on the foliage. Here's how:

Ingredients:Plant ash.

Because plant ash is the ash after plant burning, almost all the mineral elements contained in plants are contained in plant ash. The most abundant of them is potassiumMore than 90% of them are water-soluble, in the form of carbonates, nutrients are easily soluble in water.

Organic fertilizer production method:Take 2 kg of plant ash, pour 20 kg of water (1:10 ratio), stir for 5 minutes, soak and stand overnight, take the supernatant, and spray it on the foliar surface.

How to make green insecticides:Take 2 kg of plant ash, pour 10 kg of water (1:5 ratio), stir for 5 minutes, soak and let stand overnight, and take the supernatant.

Spraying fruits, vegetables and flowers can control pests such as aphids, cabbage worms and maggots from leeks and garlic on plants.

Remarks:

1.Protecting the leaves and fruits:Foliar spraying of plant ash leaching solution can promote the thickness of crop stems, increase the synthesis of chlorophyll, help prevent leaf yellowing and early fall, reduce the occurrence of leaf fall, flower drop and fruit drop, and help promote fruit expansion and coloring.

2.Pest control:It helps to control aphids, cabbage worms, and root maggot adults, and the plant ash is sprinkled directly on the roots or soil of vegetables, which helps to control root maggot larvae (larvae are generally mostly in the soil);

3.Administered alone:Because the plant ash is alkaline, when it is applied to the soil as fertilizer, it should not be mixed with acidic nitrogen fertilizer, so as not to cause nitrogen volatilization and loss of nutrients.

For example, ammonium sulfate, ammonium chloride, ammonium bicarbonate and other ammonium nitrogen fertilizers, as well as human manure, manure and other farm fertilizers.

First, the role of plant ash is a very high-quality alkaline potassium fertilizer and medium and micro fertilizer, which contains a variety of trace elements required for plant growth, has the effect of promoting crop growth, development and maturity, improving the quality of agricultural products, increasing yield, etc., note that plant ash is an alkaline fertilizer, usually can not be mixed with acid fertilizer, to avoid chemical reactions, reduce fertilizer efficiency, the main role is, can promote the formation of plant roots, enhance root ability, cultivate strong seedlings, promote reproductive growth, promote fruit ripeningIt has the effect of inhibiting and assisting some pests and diseases of crops, and regulates and improves the acidic environment for crop survival.

Mix the plant ash with a little pesticide, put it in a bottle, add 500ml of water, mix it thoroughly, and spray it on the plant seedlings.
