Polyether modified trisiloxane is currently the most widely used synergistic agent in agricultural production. When mixed with corresponding pesticides, it can significantly improve the utilization rate of pesticides. What are the characteristics of adding polyether modified trisiloxane when administering medicine?


1. Super strong expansion ability, more conducive to wetting the target drug with liquid medicine


The expansibility of the medicinal liquid on the surface of plant leaves or insect bodies directly affects the level of efficacy.


Most plant leaf surfaces and insect body surfaces have epidermal cuticles, waxy layers, villi, or rough surfaces that are difficult to adhere to medication. Spraying medication diluted with water directly on these surfaces is very unstable.


Adding polyether modified trisiloxane can effectively solve these problems, thereby maximizing the effectiveness of the drug.


2. Smaller contact angle can significantly improve the spreading ability of the drug solution on the drug target


The smaller the contact angle between the liquid and the surface of leaves or pests when sprayed, the better the expansion and distribution of the liquid, and the better the medication effect.


Polyether modified trisiloxane has a very low surface tension, which can significantly reduce the contact angle of the liquid sprayed on the surface of plant leaves and pests, thus achieving better drug efficacy.


3. Strong scalability, which can significantly increase the coverage area of the drug on the target substance


The addition of polyether modified trisiloxane solution can double the coverage area on crop leaves, which is also an important reason why the use of polyether modified trisiloxane agents can significantly improve the effectiveness of disease and pest control.


4. Strong penetration absorption and resistance to rainwater erosion, greatly improving the stability of the medicine solution


Polyether modified trisiloxane can make the liquid sprayed on plant leaves and insect surfaces penetrate the target object faster, better, and more through the stomata.


It also has excellent resistance to rainwater erosion.


The effect of adding polyether modified trisiloxane to the liquid medicine is also so obvious, which cannot be compared to using drugs or foliar fertilizers alone.



Polyether modified trisiloxane is different from other ordinary drugs or active agents

Polyether modified trisiloxane has lower surface tension, stronger diffusion and spreading properties, adhesion and permeability, wettability, temperature resistance, and rain erosion resistance.


★ Can be used in combination with the vast majority of fungicides, insecticides, herbicides, plant growth regulators, and foliar fertilizers on the market, significantly improving the effectiveness of various medicinal liquids.


★ The surface of polyether modified trisiloxane has strong expansion function, making the coverage area of the medicine wider and more uniform, and increasing the amount of medicine absorbed or penetrated on the surface of leaves and insects, resulting in more significant prevention and control effects.


For example, when spraying a solution modified with polyether trisiloxane, as long as a few drops of the solution stick to the leaves, the solution can spread and cover the entire leaf; If a liquid medicine is sprayed directly with water, it will not have this effect.
