Scientific use of pesticide chemicals

Where a pesticide mixed with or through the mixing process with the original drug to improve the physical and chemical properties of formulations to improve efficacy, ease of use of substances, collectively known as the pesticide adjuvant, referred to as pesticide additives. 

    In general, the pesticide itself is not biologically active additives, but the additives used properly or not, the efficacy of pesticide formulations significantly affect performance. For example, with 10% and 30% diesel propanil mixture of EC, with and without diesel Propanil 20% EC herbicide similar effect, but the amount of propanil is a difference of 1 times; use of Bordeaux mixture, if added, in which 0.2% ~ 0.3% glue, rain erosion-resistant, and can improve the disease prevention effects. The rational use of pesticide chemicals, pharmaceutical plants are often also improve safety and reduce the toxicity to humans and animals. 

    Packing: Packing can be used to dilute the pesticide and reducing the amount of the original medicine, so that the original drug to facilitate mechanical grinding to increase the dispersion of the original drug is manufactured powder or wettable powder filling material, such as clay, clay, kaolin, diatomite , pyrophyllite, talc and so on. 

    Wet development agent: agent is the wet can reduce the development of the surface tension of water, so water easily wet the solid surface additives. The liquid spray to the surface by the drug, easy-to-surface moisture in the distribution by the drug and improve the control effect. Such as tea, dry, paper pulp waste liquid, washing powder, opened the powder. 

    Emulsifier: make the original immiscible two-phase liquid (such as oil and water) to form an opaque or translucent cream liquid additives, known as the emulsifier. Such as Turkey marked, double-glycerol sodium laurate, polyoxyethylene castor oil, ethyl ether, benzene-based Poly ether and so on. 

    Dispersant: divided into two types. A liquid dispersing agent for the pesticide is a substance with high viscosity, through the mechanical action, can be fused into a colloidal dispersion of pesticide granules, such as sticky honey concentrate waste, paper pulp waste liquid concentrates; other dispersants for pesticide formulations, to prevent powder Xu junction, so that when the powder spraying pesticides can well be dispersed. 

    Adhesives: adhesives, is to increase the performance of pesticides on the solid surface adhesive additives. After pharmaceutical improved adhesion may be resistant to rain erosion, improve the effectiveness of pesticide residues. Often adding an appropriate amount in the powder viscosity mineral oil, liquid pesticides in adding the right amount of starch paste, gelatin, etc.. 

    Stabilizer: stabilizer, also known as anticoagulants, to prevent pesticide formulations (WP) the physical properties of deterioration during storage (suspension rate decreased). 

    Anti-solution agent: that can prevent the active ingredients in pesticide formulations during the decomposition of the auxiliary storage. Some of the anti-stabilizing agent solution for a class of agents include, for example, to add some anti-solution emulsion agent can improve emulsion stability. 

    Synergist: does not have insecticidal, bactericidal effect, but can improve the original drug for insecticidal, fungicidal effect of additives. 

Solvents: solvent is to dissolve pesticide additives, pesticides used for processing of EC. Such as benzene and xylene.
