Correct selection of pesticide spray additives

Jul 5, 2021

In today's agricultural production, pesticide spray adjuvants are very popular. Pesticide spray auxiliaries are divided into two categories, namely active auxiliaries, including surfactants, wetting agents, oil-based, adhesives and penetrants; special-purpose spray auxiliaries, including buffers or acidifiers or pH changes Agents, water quality regulators, anti-drift agents, thickeners, blending agents. There are a few things to pay attention to when choosing pesticide spray additives:

Pesticide spraying aid is to add any substance in the chemical solution on the spot when pesticides are used to increase the activity of the active ingredients and improve the physical properties of the chemical solution. In order to distinguish it from the additives added in pesticide formulations, it is called pesticide spraying aid.

Correct selection and use of pesticide spray additives
1. Choose agricultural spray additives specially developed for agriculture and forestry, such as agricultural silicone additives. Do not use industrial products or household detergents and washing powders to avoid destroying the activity of pesticides.
2. Many pesticide formulations already contain additives necessary to improve the performance of pesticides, and spray additives are generally not required.
3. Make sure that the spray adjuvant used has been fully tested for effectiveness. For products with doubts or uncertainties, small-scale tests should be carried out before large-scale use.
4. Specific pesticides require specific additives, which must be selected correctly when using them.
5. The recommended pesticide adjuvants may change due to changes in formulations or due to changes in application technology procedures.
6. No pesticide spraying additives are required under any spraying conditions. A liquid immersion test can be performed to detect whether the spray liquid contains too much wetting agent.
7. Record the safety, compatibility and effectiveness of pesticide mixing, including pesticide formulations, adjuvants, dosages, etc. Improper use or excessive use of additives may reduce efficacy or cause harm. Read the labels of pesticides and adjuvants carefully to ensure that the selected adjuvant matches the application site, target pests, medical equipment, and even the pesticides used.

In today's agriculture, pesticide ground additives are very popular. Pesticide adjuvants are divided into different categories, including properties that have adjuvant effects, wetting agents, base oils, special adhesives and water droplets; use spray adjuvants, including buffer acidifiers or buffer acidifiers, water quality adjustment Agent, anti-absorbent, dense, blending agent. There are several things to pay attention to when choosing different diffusing agents or additives:

Spray adjuvant, also known as tank mixing adjuvant, is an auxiliary product that is added to the liquid tank with the pesticide when it is used. Spray additives can be packaged separately because they can not be added to the pesticide formulations. When pesticides are used, they can be added to the spray liquid, which can reduce the surface tension of the liquid, improve the wetting and permeability, increase the amount of droplets deposited on the leaf surface, and extend The moisturizing time of the mist drops, promotes the absorption of the liquid medicine in the plant body, etc. to achieve the purpose of increasing the efficacy of the medicine.
Pesticide adjuvant is the general name of various auxiliary materials used in the processing and application of pesticide formulations. Although it is a type of adjuvant, it generally has no biological activity, but it is an indispensable addition in the formulation of the formulation or during application. Things. Each pesticide adjuvant has a specific function: some can dilute the original drug; some can help the original drug to be evenly dispersed in the preparation; some can prevent the droplets from agglomerating and becoming larger; some can increase the wetting of the particles Sex, adhesion or permeability; some can prevent the decomposition of active ingredients; some can increase the safety of application, and so on. In short, the function of pesticide adjuvants is nothing more than improving the physical or chemical properties of pesticides, maximizing efficacy or contributing to safe application.
