Model:NV-SiF9508,NV-SiF9548，NV-SiF9577,NV-SiF9586

Key features and typical benefits:

1.Superspreader,which improves the spray coverage;

2.Promotes rapid uptake of agrochemicals (permeability and rainfastness)

3.Reduces environmental pollution caused by agrochemicals.

How to Use:

1. As a tank-side adjuvant

NV-SiF9508/NV-SiF9548/SiF9577/SiF9586 is used to improve spray coverage,improve uptake or to reduce spray volume.It is the most effective as a tank-side adjuvant when spray mixtures are (i) within a PH range of 6-8,and (ii) prepare the spray mixture for immediately use or within 24h preparation.

It achieves full performance at very low use-levels,often 0.1 to 0.5% will be sufficient.Once the full performance of it has been reached,a further increase in the NV-SiF9508/NV-SiF9548/SiF9577/SiF9586 concentration will show no effect.We recommend testing first at a concentration of 1% and afterwards lowering the concentration to the point at that still full performance is achieved.

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%

The use rate is depended on crop,agrochemical and spray volume requirements.

When using, first dissolve the agrochemicals, add NV-SiF9548/SiF9577/SiF9586 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.

2. In Agrochemical Formulations

NV-SiF9508/NV-SiF9548/SiF9577/SiF9586 can be used as a component in agrochemical formulations.

Silicon surfactant is stable and it can keep surface activities for long time in PH=6-8 liquid. But if the liquid mixtures is PH=5-6 or PH=8-9,the surface activity lows down obviously after being laid aside for 24h.

Although silicone surfactants are subject to hydrolysis under acidic or basic conditions,optimum performance is achieved by buffering the formulation to PH6.5-7.5.

Additional,it is recommended that NV-SiF9548/SiF9577/SiF9586 be used at concentration of at least 0.5%-8%,based on total formulations. The user should adjust the amount of NV-SiF9548/SiF9577/SiF9586 according to different kinds of formulations to reach the most effective and most economical result. Do compatibility tests and stepwise tests before usage.
