3. Silicone penetrant

Silicone penetrant has a very low surface tension, after adding pesticides in a certain proportion, the pesticide can make the pesticide on the surface of the plant have super spreadability, permeability and dispersion, wettability, efficient systemic and conductivity, especially in the foliar wax layer and other difficult to wet the surface to achieve rapid wetting, dispersion, and penetrate into the pores of the plant, improve the efficacy, rain resistance, so that the effect is long-lasting.

Note: Phosphine, thiamethoxam and silicone penetrant complement each other, all of which are indispensable, and can be used together to kill scale insects. When applied, spray the leaves and spray the wet soil surface or irrigate the roots to kill the insect eggs in the soil, so that it can be killed, and the proportion of the drug is 1:

1500 times, take 1 gram of each agent, take a total of 3 grams, and then add 1500 grams of water.

Reasonable fertilization, not partial application of a certain fertilizer. Balanced nutrition helps the tree to become more resistant to a small number of pests and diseases. In autumn, the overwintering nymphs on the branches are manually brushed to prevent the adult from endangering the health of the tree in the coming year; Once a dead plant is found, it should be burned in time to prevent harm to adjacent fruit trees.

There are many kinds of scale insects, the harmful plants are also very wide, crops, fruit trees, green plants and flowers, succulents, etc. will suffer from its poisonous hands, and the scale insect reproduction ability is amazing, once the individual leaves occur, the treatment is not timely, the whole plant suffers together, and even infects the adjacent potted plants, because of its small individual, mostly occurs in the hidden parts, often not easy to detect, when the insect pest area is also relatively large, it is difficult to treat the root by physical methods alone, and auxiliary pesticides are needed to completely eliminate and kill.

The first is to spray the potion at the young stage of the scale insects, because the scale insects will form a hard shell on the surface of the adult stage, and the potion has no effect on it, and second, the potion is mixed with water for watering, so that the cotton can absorb the potion into the body.

1. Vegetable oil

Vegetable oil is a physical insecticidal method, the safest, non-toxic and harmless physical killing method, killing thrips, aphids, scale insects and other common insects, these diseases, have a very good effect, because mineral oil.

Its main function is to cover the scale insect, these slimy drugs, so that the scale insect, or other insects can not breathe alive, suffocation, let him breathe to death, this is a function of mineral oil, about 100-500 times of water spray, to the infected insect leaves, can be effectively killed, this is the simplest and harmless method, suitable for indoor insecticide.

2. Acetamiprid, aphid lice net, scale must be cured and so on

When killing it, you must pay attention to adding a few grams of white vinegar to the water, such as 500 ml of water, adding 1-2 grams of acetamiprid or cocoon, and then adding two or three grams of white vinegar, spraying it, because the acidic substances of white vinegar can melt the outside of the scale insect, so that the drug can completely penetrate into the inside of the insect, destroy it from the inside out, and kill the insect.
