Scientific compounding of pesticides

This type of compound is most widely used in combination with herbicides and herbicides. Generally, a long-lasting herbicide is combined with a herbicide having a short duration, and a systemic herbicide is combined with a contact herbicide. In addition, insecticidal spectrum complementation is also carried out, such as a herbicide for killing monocotyledons and a herbicide for killing dicotyledons, and a herbicide for killing broadleaf weeds is mixed with a herbicide for killing grass weeds. Butachlor has a good effect in controlling most of the annual weeds, but it has no obvious effect on controlling broadleaf weeds such as ragweed and kohlrabi, while cisplatin has high control effect on broadleaf grass. The compounded butyl granules can complement each other. In addition, the formulas that have been applied well in practice include chlorpyrifos plus dimethyltetrachloride, herbicide ether plus dimethyltetrachloride, herbicide plus dimethyltetrachloride, chlorpyrifos plus diuron, and chloromeron. Add chlorpyrifos, trifluralin plus glutamate, paraquat plus simazine.

Insecticides and insecticides are compounded with a combination of organic phosphorus and organic phosphorus, such as methyl parathion or ethyl parathion mixed with trichlorfon or four enemy powders, methamidophos and methamidophos Dichlorvos mixed with dichlorvos, trichlorfon and malathion, etc.; organic phosphorus combined with pyrethroids, such as omethoate mixed with omethoate and fenvalerate Ethyl esters of ester, dimethoate and pyrethroid, chrysanthemum mixed with methamidophos and deltamethrin; compounding of carbamate and organophosphorus, such as leaf 蝉Yema emulsifiable concentrate mixed with marathon, granules mixed with carbofuran and monocrotophos; compounded with organic nitrogen and carbamic acid, such as two-speed wettable powder mixed with insecticidal double and acesulfame.

The combination of insecticide and synergist firstly found that sesamin of sesame oil has synergistic effect on natural pyrethrin, and later developed synergistic ether, synergistic ester, synergistic and synergistic phosphorus. These synergists do not have a direct poisoning effect on pests, but they are added to the insecticide to resist the action of oxidase, prevent the pesticide from being decomposed, and enhance the effect of the pesticide. However, synergists do not make all pesticides more effective, and the synergistic effect on different pesticides is not the same.

The combination of the bactericide and the bactericide is generally a combination of a systemic bactericidal agent having a therapeutic effect and a bactericide having a protective effect. After being absorbed by the plant body, the systemic fungicide can be transported to various parts of the plant body to kill the bacteria in the plant. The protective fungicide remains on the surface of the plant to prevent the invasion of pathogens. For example, dystrophic manganese ZnZ is a combination of systemic therapeutic ruthenium and protective mancozeb; compound carbendazim is compounded by carbendazim and Jinggangmycin; The agent is made up of carbendazim and thiram.

The combination of fungicides and insecticides is mainly for the purpose of sterilizing and killing insects. For example, Daofengsan, Xizhiyin and Chunleimycin can be combined to treat the stem borer, rice warm disease, and planthopper and leafhopper.

Stainless Steel Sliding Door

Characteristics and Advantages

(1) Intelligent control design: adjustable main parameter and secondary parameter automatically according to the weight of door leaves;

(2) Low noise: Special static sound track, integration of motor, worm-gear and retarder.

(3) Anti-clamping function: automatically reverse when meeting barriers;

(4) Unique electronic motor lock: the motor will lock up when the door is forced to open.(controlled by remote or switch)

(5) Tighten force: seal door when closed, power consumption approximately 10W under standby;

(6) Advanced brushless motor(36V,100W) can automatically adopt different heavy door leaves;

(7) Bi-doors inter-locking: one of the door leaves always remains closing;

(8)Safety sensor terminal: sensor stops working when door closed;

(9)Unique coating technology: never rusty;

(10)Easy and convenient to install;

(11)Working Process: when the door leaf closes to the right place, the door leaf will slightly shift to the door frame and the ground. The rubbers on the four sides of the door leaf will completely combine with door frame and ground, which ensures air tightness. When the door is open, the rubbers will separate from door frame and ground, which avoids contraction on the ground.

Technical Details:

(1) Rubber lining sealing technology combined with V groove on the guide rail enables the door completely sealed when the door closed;

(2)Special door body location technology. Semicircular surface beam on the ground matches with the V style groove at the bottom of door leaf, which stop the door from swing and make sure it moves stable and smooth;

(3) The door body decorated with matte stainless steel or spray surface, and on the middle and both sides with sealing stripes to ensure the hermetic effect.

(4)Feet sensor switch applied to avoid contagion;
