Agricultural Silicone Spreading Agent Sylic S7800 (CY-408)

Agricultural Silicone Spreading Agent S7800 is a polyether modified trisiloxane, which is a silicone surfactant with good spreadability and permeability. 

In the process of spraying pesticides, it has the characteristics of increasing efficiency, saving labor, saving water and saving medicine. 

It can make sprayed agricultural chemicals play a better role, spread more easily, absorb faster and not easily washed down, and have "rain-proof washout".

Funtions and Features 

1. Super spreading agent for solution and emulsion.

2. Reduce the amount of spraying and increase the spraying coverage.

3. Promotes rapid absorption of pesticides and resistance to rainfall washout.

4. Non-ionic surfactant.

Agricultural Silicone Spreading Agent Sylic S7800 can greatly reduce the surface tension of the pesticide spray solution, increase the coverage of the spray, reduce the contact angle between the drug solution and the leaf surface, and enhance the wetting, adhesion and adhesion of the drug solution on the surface of plants or diseases It exhibits performance and allows pesticides to be absorbed through the stomata of the leaves, which can improve the efficacy, reduce the dosage of pesticides, save costs, and reduce the pollution of pesticides to the environment.

Outstanding performance

Agricultural Silicone Spreading Agent Sylic S7800 has extremely strong spreading performance. First of all, we compared the spreading effect of the liquid without synergist, added Tween-20 and Agricultural Silicone Spreading Agent Sylic S7800 on the leaf surface. The results show that the expansion diameter of the liquid added with Agricultural Silicone Spreading Agent Sylic S7800 is up to 7 times that without the synergist. The medicine liquid can be spread on the blade surface more evenly, directly improving the effective utilization rate of the pesticide, and reducing the loss of the medicine liquid.

Agricultural Silicone Spreading Agent

Subsequently, the pesticide chlorothalonil was evenly sprayed on the cucumber leaves. After adding Agricultural Silicone Spreading Agent Sylic S7800, the pesticide chlorothalonil sprayed on the cucumber leaf surface was reduced by 52.9%, and the drug droplets were crushed evenly, so that the leaves showed moisture. While reducing the amount of use, the adhesion rate of pesticides on the surface of the leaves increased by 62.5%, which improved the efficacy.

Spraying pesticides may cause damage to the plants themselves while preventing pests and diseases. After spraying 2,000 times of chlorpyrifos, we caused serious damage to the cucumber leaves, which inhibited the photosynthesis of the plants. The uneven distribution of drug droplets caused local burns on the leaves. After adding S7800, the dosage of pesticide was reduced, the agent was spread evenly, the photosynthesis was not damaged, and the plants grew normally.

Why Silicone Spreading Agent are used in agriculture industry?

1. What are adjuvants used for in agriculture?

An adjuvant is a substance that is added to a pesticide product or pesticide spray mixture to enhance the pesticide's performance and/ or the physical properties of the spray mixture.

2. What are adjuvants in herbicides?

An adjuvant is any substance in a herbicide formulation or added to the spray tank to improve herbicidal activity or application characteristics. Spray adjuvants are generally grouped into two broad categories--activator adjuvants and special purpose adjuvants.

3. What are the merits of agriculture adjuvants?

① It helps to disperse the effective ingredients of pesticides. Including decentrals, emulsifiers, solvents, carriers, fillers, etc.

② Help to use efficacy or extend the effect. Including stabilizers, controlling agents, efficient agents, etc.

③ Helps to prevent or control the effective ingredients of pesticides. Including moisturizers, osmotic agents, adhesives, etc.

④ Increase safety and convenience. Including drifting agents, safety agents, detoxification agents, anti -foaming agents, alert color, etc.
