In the face of aphids on plants, the best way is to use acaricides , but do you know the use of acaricides ? The following is a brief introduction to the use of acaricides, I hope to help everyone.
In order to improve the control effect and delay the production of anti-drugs by aphids on acaricides, the following points should be done in order to regulate the use of acaricides:
First, choose the best prevention and treatment period: try to choose the spraying in the early stage of the disease, when the population density and quantity are small, to increase the duration of the acaricide and reduce the number of uses. The best control period on the fruit trees is half a month after the flowering of the flowers, that is, the early hatching of the eggs of the first generation of insects and before the wheat harvest.
Second, the rotation of the use of acaricide
1. When the cockroaches, cockroaches, and pups coexist, the acaricides that are effective in the cockroaches should be used. Optional 20% 哒螨çµ(苯åŒå¾—,螨代得) WP, 41% diesel 哒螨çµ(金霸螨,霸螨特) emulsifiable concentrate, 34% diesel 哒螨çµ(killing king, sneezing A) Acaricides such as emulsifiable concentrates and 73% of ketamine emulsifiable concentrates have the characteristics of good killing, high efficacy and full function. One of them can be used in rotation to achieve the purpose of controlling pests.
2. When the egg mites with more eggs are coexisting, a long-acting acaricide with good egg-killing effect and ovulation treatment should be used. 10% 哒四螨 (fruit full red) suspending agent, 12% 哒 螨 螨 wettable powder, 10% triazole tin tetramine (Red lion) suspension, 5% Nisolron emulsifiable concentrate. These agents can penetrate the eggs and prevent the eggs from developing and hatching, so as to control the rapid growth of the density of the mites.
3. When the damage of the two-spotted spider mites (white spider) rises, choose a special agent for killing white spiders, such as 15% simvavirus, for its small size, strong concealment, fast crawling and stronger breeding ability. Prime (Bai-Tian, ​​red and white) emulsifiable concentrate, 1% Avicochlor (white peony egg) emulsifiable concentrate, 24.5% Avi Violet (Virten) emulsifiable concentrate, 35% simvastatin (白螨霸) Emulsifiable oil.
Third, pay attention to spraying skills: Because most of the current acaricides are contact-type, some have osmotic effects, but there is no systemic acaricide. Therefore, it should be even and thoughtful when spraying, especially pay attention to the densely packed eggs on both sides of the main vein on the back of the blade. For specific operations, spray until the tree is wet to drip.

Under this category, the product of Wire Rope Clamp is mainly introduced. A wire rope clip, also called a clamp, cable clamp, wire rope clamp, U-Clip, U-Clamp, is used to fix the loose end of the loop back to the wire rope. It usually consists of a U-shaped bolt, a forged or cast saddle and two Nuts. The two layers of wire rope are placed in the U-bolt. The saddle is then fitted over the ropes on to the bolt (the saddle includes two holes to fit to the U-bolt). The nuts secure the arrangement in place.
