Active Adjuvant Chemistry and Surface Tension Reduction
Water naturally possesses high surface tension, causing spray droplets to form spherical beads that readily bounce or roll off waxy leaf cuticles.
Bond utilizes non-ionic surfactant molecules that dramatically lower the dynamic surface tension of agricultural spray solutions.
This causes droplets to flatten and spread into an ultra-thin, continuous chemical film across leaf and stem surfaces.
- Surface tension reduction: Lowers water contact angles, eliminating droplet bounce and runoff
- Cuticular spreading: Facilitates droplet penetration into dense leaf pubescence and waxy cuticles
- Rainfast sticker: Synthetic latex polymer components resist wash-off during sudden monsoonal rain showers
Compatibility Across Agrochemical Classes
Bond is non-ionic in nature, ensuring broad physical and chemical compatibility across insecticides, fungicides, herbicides, and foliar micronutrients.
Adding the adjuvant to post-emergence weedkillers significantly accelerates systemic herbicide uptake through waxy weed foliage.
- Herbicides: Enhances systemic uptake of grass and broadleaf weedkillers across tough waxy weeds
- Fungicides: Ensures uniform surface coverage and underside retention on fruit bunches and foliage
- Insecticides: Penetrates insect webbing and waxy scale or mealybug coatings
Mixing Order, Dosage, and Operator Safety
Always add Bond to the sprayer tank as the final component after wettable powders, granules, or emulsifiable concentrates have fully dissolved.
Adhere strictly to label dilution instructions, as exceeding recommended adjuvant concentrations can cause localized leaf spotting.
Wear standard protective clothing during preparation.
- Tank mixing order: Add adjuvant last to prevent premature foaming in the sprayer tank
- Precise dilution: Measure recommended milliliters per spray tank following product instructions
- Personal protection: Wear protective rubber gloves, mask, and safety goggles during handling

Common questions
What is the primary function of Willowood Bond adjuvant?
Bond acts as a non-ionic spreader, sticker, and penetrant that reduces spray droplet surface tension and improves chemical retention on leaves.
When should Bond be added to the sprayer tank?
Always add Bond as the final ingredient into the spray tank after other pesticides and fertilizers have been completely dissolved.
Does Bond help prevent pesticide wash-off in rainy weather?
Yes, its specialized sticking agents bind spray droplets to the plant wax layer, providing rainfast protection.
