Agricultural drug type selection should pay attention

At present, there are many dosage forms of pesticides. Some of the dosage forms have the same name but different uses. Some of the dosage forms have the same purpose and different methods of use. Here is how to choose a pesticide dosage form.
The difference in the presence of pesticides. Therefore, in the selection, we must first consider the control object of the crop, the equipment to be applied and the conditions of use. At present, most of the pesticide formulations in China are suitable for spray, in which emulsifiable concentrates and wettable powders are mainly used, and one is a suspending agent. The main differences between the three dosage forms are as follows:
First, the efficacy of the pesticide's emulsifiable concentrate is significantly higher than that of the suspending agent and the wettable powder. The active ingredient of the same pesticide is preferably emulsifiable. The fungicide for foliar spray, generally in the form of oil as a medium, is not beneficial to the bactericidal action, so a suspending agent or a wettable powder should be selected. The herbicide for foliar spraying has a waxy layer on the surface of the weed leaves, and the emulsion containing the organic solvent, the concentrated emulsion, the suspending agent and the like can be selected. Herbicides, granules and other dosage forms that can be used in the preparation of toxic soils are used more frequently in paddy fields or soils.
Secondly, as an alternative formulation for emulsifiable concentrate, the efficacy of the suspending agent is second to that of the emulsifiable concentrate, but it is significantly higher than that of the WP, and the various auxiliaries thereof are beneficial for the adhesion of the granules to the surface of the living body, thereby improving the efficacy. . Compared with emulsifiable concentrates, thick emulsions and microemulsions do not use or use less organic solvents. They are safer to use and have better efficacy. However, the manufacturing cost is slightly higher and the price is slightly higher.
Third, from the safety considerations of the application personnel, spraying in hot weather, oil-based emulsion is easy to cause poisoning, it is best to use similar water-based dosage forms, such as wettable powder, suspoemulsion, soluble powder , water-dispersible granules, and the like.
Fourth, there is currently the same dosage form of the same active ingredient pesticide in China, but there are many different levels of preparations. When purchasing, you should choose a high-content preparation, which can be used to reduce the cost of use.

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;
