Pure plant pesticides hidden in the fields

Garlic stems and leaves

Cut the stems of the garlic stems into small pieces of one centimeter and sprinkle them in the early rice fields to let 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.

Nettle leaf

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. Soak 1 kg of ramie leaf powder and water 16-20 kg, and infuse it with a kettle to cure onions, leeks, garlic, radish, Chinese cabbage, cabbage caterpillars, and insectivores. The nettle leaves can also be made into leachate and sprinkled into toilets, pig pens, pits, etc., which have obvious effects on killing mosquito larvae and maggots.

Platycladus

Crush it, add an equal amount of water, squeeze out the original 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 leaf

Smash it, add water 3 times soak for 1 day or cook for 30 minutes, filter and spray, can control cabbage caterpillars, mites, mites and so on. 5 times water infusion of willow leaves can inhibit wheat rust.

Mulberry leaf

Add 5 times of water, boil it into a stock solution, add 2 kg of water per 0.5 kg of stock solution, or spray 10 times of water spray on 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

Chop it, add 10 times of water, cook for 30 minutes, spray after cooling, can control cotton aphid, red spider, cabbage caterpillar.

Black Coating

Black coating is a type of Surface Treatment used to provide a durable, aesthetic and protective finish to metal parts. It is applied to a range of substrates, including steel, aluminum, and titanium, through various processes such as painting, chemical baths or physical deposition.


Black coating provides an attractive, matte finish that reduces glare and reflections. It is commonly used in industries such as automotive, aerospace, and firearms, where aesthetics and durability are essential. The black coating can also be used for functional purposes, such as to reduce friction and wear.


One of the most common types of black coating is black oxide. Black oxide is created through a controlled chemical reaction that forms a layer of black iron oxide on the surface of the metal. This process enhances the corrosion resistance of the substrate and provides a uniform and attractive black finish. Black oxide is also used to provide a matte black finish to gun parts, as well as to increase the conductivity of electrical components.


Another type of black coating is powder coating, which involves applying a dry powder to the surface of the substrate and baking it in an oven. This process creates a durable, weather-resistant finish that is resistant to damage from UV rays and other environmental factors. Powder coating is widely used in the automotive and manufacturing industries, where it provides a long-lasting, high-gloss black finish.


Finally, black coating can also be achieved through physical vapor deposition (PVD). This involves depositing a thin layer of black material onto the substrate through a vacuum chamber. PVD black coatings are very durable, and are often used in high-precision applications such as medical instruments and aerospace components.


In conclusion, black coating is a versatile and effective way to provide a durable, aesthetic, and protective finish to metal parts. Its visual appeal, corrosion resistance, and wear resistance make it a popular choice in a variety of industries and applications. Whether applied through chemical baths or physical vapor deposition, black coating plays an important role in enhancing the performance and longevity of metal parts.
