Product Description

Agricultural Silicone Spreading & Penetrating Agent RO-888

Agricultural Silicone Spreading and Penetrating Agent RO-888 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, RO-888 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

Feature

Super spreading and penetrating agent.

To reduce the dosage of agrochemical spraying agent.

To promote the rapid uptake of the agrochemical (tolerance to rainfall)

Non-ionic.

Application

(1) . Used as spray adjuvant: RO-888 can increase the coverage of the spraying agent, promote the uptake and decrease the dosage of the spraying agent. The RO-888 is the most effective when spray mixtures are

(i) within a PH range of 6-8

(ii) prepare the spray mixture for immediately use or within 24h preparation.

(2). Used in agrochemical formulations: RO-888 can be added in the original pesticide.

Use method

1) Used of spray mixed in drum

In general, add RO-888 (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:

Item	Standard
Plant promote regulator	0.025% to 0.05%
Herbicide	0.025% to 0.15%
Insecticide	0.025% to 0.1%
Fungicide	0.015% to 0.05%
Fertilizers and Micronutrients	0.015% to 0.1%

(a) Note: use rates are dependent on crop, agrochemical and spray volume requirements.

When using, first dissolve the pesticide, add RO-888 after the uniform mixture of 80% water, then add water to 100% and mix them uniformly. It is advised that when using Agricultural Silicone Spreading and Penetrating Agent, the water amount reduced to 1/2 of the normal (suggested) or 2/3, average pesticide usage reduced to 70-80% of the normal. Using the small aperture nozzle will quicken the spray speed.

1) 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. The user should adjust the amount of Agricultural Silicone Spreading and Penetrating Agent according to different kinds of pesticide and prescription to reach the most effective and most economical result. Do compatibility tests and stepwise tests before usage.
