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!

Oversized Item Delivery Options

Oversized, heavy, and structural goods ship via specialist freight. Freight is calculated at checkout from estimated packaged volumetric or physical weight. Carrier depot audits may adjust the rate — if the increase exceeds 10%, we will contact you before processing.

Available options include:

✔ Delivery to your closest depot for pickup — default method
✔ Direct delivery — requires an operational forklift on site unless Tailgate Delivery has been specifically requested and quoted (contact us — this cannot be selected at checkout)
✔ Tailgate hydraulic lift delivery — must be specifically requested; contact us for a quote (not available as a checkout option; extra fees apply; required if you do not have a forklift)
✔ Forklift loading at our warehouse (no extra charge if you arrange your own freight)

Important Notes:

• Shipping costs vary by location and method
• Any carton or consignment over 25–30kg (or over 200cm) must be palletised
• Without a specifically requested and paid Tailgate Delivery quote, palletised freight requires a forklift on site — otherwise the carrier will redirect to the nearest depot
• Bulky and oversized items cannot be delivered to a PO Box — provide a physical street address
• Failed deliveries, locked gates, unattended sites, or incorrect business/forklift declarations may incur carrier redelivery, demurrage, and restocking fees as set out in our Terms & Conditions

Business Delivery:

• Selecting a business/commercial delivery rate warrants that the address has an operational forklift and certified operator during business hours
• If the carrier cannot unload, the consignment may be redirected to a depot and secondary fees may apply
• Additional fees may apply for failed delivery attempts due to lack of appropriate unloading equipment

See our Terms & Conditions (Article 8) for full freight and delivery rules.

Important Note on Availability & Shipping

Our warehouse is a logistics hub, not a retail showroom. Listing a product online does not mean it is stored at our Thomastown warehouse — many lines ship from supplier hubs (split fulfilment may apply).

How lead times work:

• Product page ETA: The Estimated Time of Arrival (ETA) / lead-time badge shown on the product page at checkout is the agreed delivery timeframe for that order under Australian Consumer Law.
• Metro baselines: Advertised ETAs apply to standard metropolitan zones. Regional and remote addresses may take longer and may attract surcharges.
• Peak seasons: Orders in March–May, August–October, EOFY (June), Black Friday/Cyber Monday (November), and Christmas/New Year (December–January) may automatically add a 2–4 week buffer beyond the product page ETA.
• Supplier-dependent / backordered items: If stock is delayed, we will notify you with a revised ETA. You then have 7 days to accept the new timeframe or cancel for a full refund.
• Adloheat: Custom-made products from Adloheat (Pakenham, VIC) may take 4–12 weeks depending on the order.

Full fulfilment, cancellation, and freight rules are in our Terms & Conditions.
