Vasili’s CGWS Citrus Gall Wasp Spray 200g - Natural Kaolin Barrier Protectant

Vasili’s CGWS Citrus Gall Wasp Spray 200g - Natural Kaolin Barrier Protectant

Protect your lemons, limes, oranges, and grapefruits from the devastating damage of Citrus Gall Wasp with Vasili’s CGWS. As our best-selling organic defence product, this highly effective wettable powder is formulated with 950g/kg of processed and refined kaolin clay. When sprayed onto foliage, it creates a fine, particle-based physical barrier film over young, tender stems and soft spring growth, completely deterring adult wasps from landing and depositing eggs inside the branches.

Optimised for total tree health, CGWS acts as a non-toxic physical deterrent rather than a harsh chemical pesticide. Originally developed as a solar radiation and heat-stress protectant, this dual-action kaolin film shields vulnerable citrus bark from intense summer sunburn while reducing gall formation by over 90% when applied during peak wasp emergence windows. Safe for non-target beneficial insects, it is an essential seasonal staple for organic gardeners and fruit enthusiasts.

Best For: Home gardeners, citrus enthusiasts, and organic growers seeking a proven, non-chemical physical barrier to prevent Citrus Gall Wasp damage, reduce heat stress, and protect young trees from sunburn.

Key Features:

• High-Purity Kaolin Barrier Film: Contains 950g/kg of refined kaolin clay that coats delicate stems in a physical particle film, preventing female wasps from piercing the wood to lay eggs.
• Proven Field Efficacy (Over 90% Reduction): Field trials demonstrate a significant decrease in gall formation. Achieve over 90% reduction when applied consistently during spring emergence.
• Dual Sunburn & Heat Stress Defence: Reflects excessive ultraviolet radiation and lowers canopy temperatures, protecting tender spring flushes from heat scorch during extreme hot spells.
• Non-Toxic & Beneficial-Friendly: Contains no synthetic neurotoxic insecticides, making it safe for birds, bees, and predatory insects while leaving no harmful residues on developing fruit.
• Easy-Mix Wettable Powder: Suspends smoothly in water for effortless application through standard pressure sprayers or garden atomisers.

Primary Garden & Orchard Uses

• Spring Gall Wasp Prevention: Spraying new green growth flushes from early spring to late autumn to prevent adult wasps from laying eggs.
• Summer Sunburn Protection: Coating young or heavily pruned citrus trees during hot months to prevent bark splitting and leaf scorch.
• Organic Pest Management (IPM): Integrating a non-chemical physical barrier into home orchard maintenance to reduce dependence on systemic sprays.

Pro Tip & Mixing Instructions: For the best results, start spraying in early spring as soon as new green shoots appear and adult wasps begin emerging from old galls.

Initial Mix: Pre-mix 50g (approx. 3 tablespoons) of powder in a small container with a little water, stirring constantly into a smooth paste to prevent clotting. Pour into your sprayer, top up to 1 Litre with water, seal, and shake vigorously.

Maintenance Mix: Re-apply every 14 to 28 days (or after heavy rainfall) using 25g (1.5 tablespoons) per Litre to coat fresh growth. Always flush your sprayer hose and nozzle with clean water immediately after use to prevent drying kaolin from clogging the line!
