Agricultural Silicone Surfactant RH-209(organosilicone surfactant) CAS NO.27306-78-1

1.Super spreading,penetrating and wetting properties.

2.Improve the pesticide target area coating as RH-208 reduce the surface tension between and droplets and covered surface.

3.Promote pesticide rapid uptake through stoma of plant leaves.

4.Obtain great performance with very low use level always 0.025%- 0.1% of the pesticide(4000times ratio)

5.Be compatible with most agrochemicals such as fungicide,herbicide,insecticide,foliar fertilizer,plant growth regulator and RH-208 is non-toxic

6.Rainfastness, improve pesticide efficacy and increase crop conductivity.

Basic Character

Instruction

Agricultural Silicone Spreading and Penetrating Agent RH-208 is a modified Trisiloxane, and is an organic silicone surfactant with super ability of spreading. It makes the water surface tension lower down to the 20.5mN/m at the concentration of 0.1%(wt.). After the mixture with the pesticide solution at the certain proportion, it can lower the contact angel between the spray and foliage, which can enlarge the coverage of the spray. Furthermore, Runhe*208 Agricultural Silicone Spreading and Penetrating Agent can make the pesticide absorbed through the stomatal of leaves, which is extremely effective for improving efficacy, reducing amount of pesticide, saving cost, reducing environmental pollution caused by pesticides.

Use Method

Used of spray mixed in drum(Tank mix)

In general, add Agricultural Silicone Synergistic Agent RH-208(4000times) 5g in every 20kg spray. If it needs to promote the adsorption of systemic pesticide, increase the function of pesticide or reduce the amount of spray further, it should add the usage amount properly. In general, the amount is as follows:

Plant promote regulator: 0.025%-0.05%

Herbicide: 0.025%-0.15%

Pesticide: 0.025%-0.1%

Bactericide: 0.015%-0.05%

Fertilizer and trace element: 0.015%-0.1%

(2)Used of Original Pesticide

 When the product added to the original pesticide, we suggest the amount is 0.5%-8% of the original pesticide. Adjust the PH value of the pesticide prescription to 6-8.
