Pyrethrin is a natural plant-derived insecticidal active substance derived from the pyrethrum of Compositae. It contains six insecticidal active ingredients and has the special effect of killing pests quickly. It can be widely used in agriculture, forestry and animal husbandry production and urban garden pest control. field.
Pyrethrin is derived from nature and has natural degradation channels. It is the biggest advantage when it is exposed to light and is easily degraded by heat. This advantage makes it safe and safe for humans and animals when controlling pests.
Today, the Chinese pesticide network Xiaobian will summarize the " introduction to the use of pyrethrins " as follows:
Pyrethrin application
The pyrethrum has a broad spectrum of insecticides, strong knockdown force, short residual effect period, strong contact killing effect, weak stomach toxicity, no fumigation and conduction. Mainly used to control sanitary pests, such as mosquitoes, flies, bedbugs, scorpions, fleas, crickets, and fish. In agriculture, it is mainly used to control aphids, thrips, planthoppers, leafhoppers and cabbage caterpillars, leaf bees, leafhoppers, golden flower insects, and elephants.
The toxicity of pyrethrin is a low-toxic insecticide . It is safe for humans and animals. It has fast decomposition, short residual period, no residue, no pollution to the environment, but it is poisonous to fish.
Precautions for the use of pyrethrin
1, see light easy to decompose, spraying time is best selected in the evening.
2, can not be mixed with stone sulphur mixture, Bordeaux mixture, rosin mixture and other alkaline pesticides.
3. The commercial preparation should be stored in a closed container to avoid high temperature, humidity and direct sunlight.
4, strong contact killing agent, the agent must be in contact with the insect body to be effective, otherwise the effect is not good.
5, pests knock down strong, but often there is recovery, especially when the concentration of the drug is low. Therefore, the concentration should be kept too low to reduce the efficacy.

Anticorrosive Steel Pipe
Anticorrosion pipe is widely used in pipeline engineering fields such as long-distance water transportation, petroleum, chemical industry, natural gas, heat, sewage treatment, water source, bridge, steel structure, offshore water transportation piling and so on.
advantage
1. Combine the mechanical strength of steel tube with the corrosion resistance of plastic;
2. The outer wall coating reaches more than 2.5mm, resistant to scratches and scratches;
3. The inner wall friction coefficient is small, 0.0081-0.091, reducing energy consumption;
4. The inner wall meets the national health standards;
5. The inner wall is smooth and not prone to scaling, with self-cleaning function.
