Grostik

Grostik is a spray adjuvant containing Silicone-based spreader (organosilicone spray adjuvant, no active ingredient). A non-pesticidal spray adjuvant added to insecticide, fungicide or foliar-nutrient sprays. Its organosilicone chemistry lowers the surface tension of the spray so droplets spread over waxy or hairy leaves instead of beading up.

Technical Details

• Composition: Silicone-based spreader (organosilicone spray adjuvant, no active ingredient)
• Mode of action: Organosilicone surfactant - sharply lowers the surface tension of the spray solution, which is a physical surfactant effect rather than a pesticide mode of action

Features & Benefits

• Rapidly reduces surface tension for near-complete leaf coverage.
• Improves spreading on waxy, hairy or difficult-to-wet leaf surfaces.
• Can promote stomatal infiltration of the spray solution.
• Reduces spray run-off, helping active ingredients stay on the leaf.

Dosage & Application

• Application method: Tank-mix additive with foliar spray
• Always follow the crop, dose and timing given on the product label and leaflet.

Safety & Precautions

• Because it drives deeper leaf penetration, tank-mixing with some pesticides under high heat/humidity can raise the risk of leaf burn (phytotoxicity); follow label rate and avoid exceeding recommended concentration.
• Read the label before use and add only at the recommended rate to the spray solution.
• Wear gloves while handling. Avoid contact with eyes and wash hands after use.
• Keep out of reach of children. Store in a cool, dry place in the original, tightly closed container.
