How to use pesticide additives correctly
The efficacy and function of pesticide additives are used correctly. Pesticide additives are additives added to the processing or use of pesticide preparations. They are also used as pesticide adjuvants to improve the physical and chemical properties of pharmaceuticals. The auxiliaries themselves are essentially free of biological activity, but can affect the control effect. There are many varieties of pesticides, different physical and chemical properties, and different processing requirements for the dosage forms, so the additives required are also different. Common pesticide additives mainly include:
1, emulsifier
For two-phase liquids (such as oil and water) that are incompatible with each other, one of the liquids can be stably dispersed in another phase liquid with a very small liquid droplet to form an opaque or translucent emulsion. The surfactant is called an emulsifier such as calcium dodecylbenzenesulfonate. Used for processing emulsifiable concentrates, water emulsions and microemulsions.
2, wetting agent
Also known as wet spread agents, are a class of surfactants that significantly reduce the tension of the liquid-solid interface, increase the contact of the liquid with the solid surface, or increase the wetting and spreading of the solid surface. Such as saponin, sodium lauryl sulfate, pull powder and so on. It is mainly used for the processing of wettable powders, water-dispersible granules, liquid preparations and aqueous suspensions and as a spray aid.
3, dispersant
In the processing of the pesticide preparation, the solid particles in the solid-liquid dispersion system can be prevented from aggregating, and the surfactant which is uniformly dispersed in the liquid phase for a long period of time can be prevented. Such as sodium lignin sulfonate, NNO and so on. Mainly used in the processing of wettable powders, water-dispersible granules, and water suspensions.
4, penetrant
A surfactant capable of promoting the active ingredient of a pesticide into a treated object such as a plant or a pest, and is generally used for formulating a hypertonic pesticide preparation product. Such as penetrant T, fatty alcohol polyoxyethylene ether and the like.
5, adhesive
An additive that increases the adhesion of pesticides to solid surfaces. It is resistant to rainwater rinsing due to improved adhesion of the drug and improves its effectiveness. For example, adding a proper amount of mineral oil with a large amount of viscosity to the powder, and adding an appropriate amount of starch paste, gelatin, etc. to the liquid pesticide.
6, synergists
A compound that is biologically inactive but inhibits detoxification enzymes in living organisms and can greatly improve the virulence and efficacy of pesticides when mixed with certain pesticides. Such as synergistic phosphorus, synergistic ether and so on. It is of great significance for controlling and controlling resistant pests, delaying drug resistance and improving control effects.
Pesticide additives have always been the hero behind the healthy development and efficient application of pesticides. The correct and rational use of pesticides and auxiliaries will have a multiplier effect on prevention and control, reduce the use of pesticides, save water and labor, increase the effectiveness of prevention and control, and achieve “one spray and three provincesâ€, which is an important measure to implement zero-growth actions.
