Product Features

• Super Spreading and Wetting: As a non-ionic silicone surfactant, it reduces the contact angle between the spray liquid and leaf surfaces, increases spray coverage, and promotes pesticide absorption through leaf stomata.
• Rainfastness: Enhances the rainfastness of sprays, improves pesticide effectiveness, and thereby achieves synergistic effect and dosage reduction.
• Transparent Solution: Its aqueous solution is colorless and transparent.

Application Fields

• Mainly used in the agricultural field. It can be added to insecticides, fungicides, herbicides, foliar fertilizers, plant growth regulators, etc., and can also be used as a tank-mix adjuvant.

Usage Methods

• As a tank-mix adjuvant: The recommended dosage is 0.01%-0.1%, with pH 6-8. The best effect is achieved when used within 24 hours.
• Added to pesticide formulations: Since silicone surfactants hydrolyze under acidic and alkaline conditions, pH can be adjusted to 6.5-7.5 with retarders for optimal performance. The recommended dosage is 0.1%-10%.

Packaging, Storage and Transportation

• Packaging: The product is packed in 20L and 200L plastic buckets, as well as other packaging forms.
