Silicone Agricultural Adjuvant RJ-7033

This super-spreader could decrease the surface tension of liquid fiercely, making them wet the foliar surface quickly and compeletely. RJ-7033 is also particularly effective in preventing ingredient from being washed by rain(rainfast).

Note of Use

RJ-7033 can be used as a component of 0.5~8% in agrochemical formulations. Proposing of formulations pH value is 6~8. Users should adjust the usage of nonionic silicone surfactant according to different varieties and condition, in order to achieve the most cost-effective results. Prior to the use, compatibility testing and pilot ladder testing should be done.

The tank-mix:

As a tank mix additives, wetting agent RJ-7033 can improve spray coverage, promote absorption, and reduce the amount of spray. If the spray mixture PH is 5-8, and used within 24 hours after preparation, this silicone surfactant would act well.

Usually we add 0.025% -0.1% silicone surfactant in the low spray volume to achieve sufficient coverage.

The typical usage is as follows:

Usage of silicone surfactant RJ-7033	Volume
Plant Growth Regulator	0.025-0.05%
Herbicide	0.025-0.15%
Pesticides	0.025-0.1%
Antiseptic	0.015-0.05%
Fertilizers and trace elements	0.015-0.1%
