Are pesticide synergists the same as adjuvants?

The mechanism of action of pesticide synergists is mainly to inhibit or weaken the detoxification and pesticide prevention effect of targets (pests, weeds, bacteria, etc.) on pesticide activity, delay the metabolism rate of pesticides in the control object, and increase the biological control effect. The synergist itself is inactive, but when mixed with the corresponding pesticides, it can significantly improve its wetting, spreading, dispersion, retention and permeation properties, reduce the drift of the spray liquid with the wind (air flow), prevent or reduce the damage to adjacent sensitive crops, etc., and is conducive to the spread and adhesion of the liquid medicine on the foliage, reduce the decomposition of the active ingredients in the pesticide preparation by ultraviolet rays, and achieve the purpose of prolonging the validity period of the drug, improving its biological activity, reducing the dosage, reducing costs, and protecting the ecological environment.

Pesticide additives can be roughly divided into: inorganic minerals; Natural substances of living beings; Organic synthetic compounds, which can be divided into two categories: surfactants and non-surfactants.

Commonly used additives are in the following categories:

Fillers and carriers.

Emulsifiers. Dispersants.

Humectant. Spreader.

Therefore, pesticide synergists and additives are not the same.

Synergists and additives are generally non-biologically inactive or have low bioactivity.

Synergists can significantly enhance the activity of active ingredients.

The role of the additive is only to improve the dispersion of the active ingredient and improve the utilization rate of the active ingredient during the application process.

Pesticide additives and synergists, as the name suggests, generally play a synergistic role after mixing.

The main purpose is to enhance the adhesion ability of the liquid medicine, as well as expand the performance or dispersion, so that the control effect can be fully exerted.

Therefore, in the process of use, the agent also needs to be mixed with some additives to improve the efficacy.

Synergist additives are simply a general term for a class of additives that can improve the effect of our usual pesticides, it itself is inactive, added to the liquid medicine can improve the ductility, penetration and adhesion of the liquid, a better synergist can eliminate the resistance of pests and diseases, better than the general synergist for practical application, so the pesticide synergist can be divided into ordinary synergist and anti-anti-synergist.

At present, synergist additives are divided into organofluorine synergists and silicone synergists, among which organofluorine synergists will be safer and more effective. When the pesticide synergist is not effective in the insecticide fungicide, the organofluorine synergist can be selected, which can eliminate the resistance problem caused by pests and diseases, and save the trouble of changing the dressing from time to time.

Pesticide synergist is simply a general term for a class of additives that can improve the effect of our usual spraying, it itself is inactive, added to the liquid medicine can improve the ductility, penetration and adhesion of the liquid, a better synergist can eliminate the resistance of pests and diseases, better than the general synergist for practical application, so the pesticide synergist can be divided into ordinary synergist and anti-synergist.

Substances that do not have drug activity in themselves, but can increase the activity of pesticides.

Specifically, check the books of pesticide processing.

Synergists generally refer to a class of substances that do not have a specific activity or have low activity, but can greatly improve the performance of the active substance when mixed with a substance with such activity. Common synergists include pesticide synergists, fertilizer synergists, concrete synergists, antibacterial synergists, desulfurization synergists, etc.

The original drug needs to add safety agents, spreaders, co-solvents, synergists, stabilizers, diffusion agents, emulsifiers, wetting agents and other additives and some other fillers to use, otherwise the efficacy is very poor and unsafe.

The efficacy of pesticides should not only depend on the content of active ingredients, but also on the type and amount of additives.

The main effects of synergists are as follows:

1. Supplement the medium and trace elements necessary for crops.

The synergistic use with fertilizers, such as various organic fertilizers, farmhouse fertilizers, ordinary fertilizers, etc., can significantly improve the utilization rate of fertilizers and meet the nutrient needs of crops at various growth stages.

2. Remove harmful substances and improve soil structure.

Purify and repair the soil, improve the soil structure, and adjust the soil fertilizer supply and fertilizer retention capacity.

3. Promote microbial activities, enhance crop stress resistance, and improve quality.

It can promote the reproduction of beneficial microorganisms, produce abundant metabolites and other active substances, and strongly promote rooting; Enhance the ability of crops to resist adverse environments, increase yields, and improve crop quality.

4. Improve fertilizer utilization rate and prolong fertilizer efficiency.

Through the synergistic effect of trace elements, urease inhibitors, biological agents, etc., the utilization efficiency of nitrogen, phosphorus and potassium fertilizer can be comprehensively improved20, and the fertilizer efficiency of nitrogen fertilizer can be extended for 90-120 days.

5. Green, environmentally friendly, broad-spectrum and efficient.

The vegetables grown are harmless, no residues, do not contain heavy metals, and have significant social, economic and ecological benefits, and are environmentally friendly green products.

Introduction to fertilizer synergist:

Fertilizer synergist is mainly composed of medium and trace elements necessary for crops, combined with urease inhibitors, ammonia stabilizers, and supplemented by biological agents, pesticides, and plant production promoters.

In addition, fertilizer synergists can also promote the reproduction of beneficial microorganisms, produce abundant metabolites and other active substances, and strongly promote rooting; Form a protective film, retain water and fertilizer, enhance the absorption capacity of plant roots, thick stems, strong seedlings, and fundamentally improve yield.

Through the synergistic effect of trace elements, urease inhibitors and biological agents, microbial organic fertilizer synergists can comprehensively improve the utilization efficiency of nitrogen, phosphorus and potassium fertilizer by about 20%, and prolong the fertilizer efficiency of nitrogen fertilizer in 90-120 days.

Fast absorption, good penetration, saving medicine, not afraid of rain 3-5 minutes after spraying.

Now because the resistance of pests and diseases is becoming more and more serious, it will directly lead to our poor effect of spraying, which should be the resistance of these drugs for pests and diseases, no matter how we spray the effect will not be obvious, when adding the synergist to eliminate resistance is a good solution, now there are many types of pesticide synergists, we choose the synergist with the elimination of resistance, that is, to solve the absorption and penetration of the liquid and play a role in eliminating resistance, it is very good to add it when playing pesticides.

There are still quite a lot of synergists, which can increase wetting and penetration, reduce surface tension, etc., so as to increase the degree of additives that increase the efficacy of the drug, which can be called synergists. Like the most is the silicone synergist, but this is not used much directly into the preparation, because the silicone additive is easy to decompose in the case of acid or alkali, and the natural synergistic effect will decrease over time, in addition, this may also affect the stability of the preparation. The best is barrel mixing, ready to use.

In addition, vegetable oils such as methyl oleate, soybean oil, nitrogen ketones, and doubling are commonly used as synergists in emulsifiable concentrates. Ammonium sulfate can also be used as a synergist for glyphosate. Mineral oil, engine oil, diesel oil, etc., have insecticidal activity or can play a synergistic role.

In fact, a good formula, choosing the right additives itself can also play a good role. Finally, the reasonable compound use of pesticides can also play a role in increasing efficiency.

Pesticide additives refer to the general term of various auxiliary substances used in pesticide preparations to improve the physical and chemical properties of pesticide preparations in addition to the active ingredients. Pesticide additives themselves have basically no biological activity, but they can significantly enhance the control effect, and facilitate the processing of pesticide raw materials and the storage of preparations. The appropriate selection of additives directly affects the efficacy of pesticide preparations.

It is a general term for a class of additives that have no biological activity in themselves, but can greatly improve the toxicity and efficacy of pesticides when mixed with a certain pesticide.
