Vasili’s Choice Citrus Guard White Spray – CGWS
- Stops Citrus Gall Wasp
- Reduce heat stress
- Increase in fruit productivity
- Increase in vitality
CGWS is a grade of refined kaolin mineral. When mixed with water and applied to citrus trees, it leaves a white barrier residue that stops Gall Wasps from penetrating and laying eggs in the tree. It also acts as a reflector and sun block reducing heat stress caused to citrus trees during extremely hot days.
Citrus Gall Wasp
These nasty pests can go unnoticed causing unrepairable damage to your citrus trees. Citrus Gall Wasps lay their eggs just beneath the surface of the citrus tree bark, acting as a host for the larvae to nest and grow inside the branch while feeding on the tree’s sap flow.
These nests cause stress to the tree, causing swelling of the branch and restricting the sap flow to the outer limbs. The most susceptible are the lemon trees, followed by orange, lime, and mandarin.
In Australia, citrus is grown in regions where high summer temperatures are common. Air temperatures exceeding 28°C can cause trees to shut down, thereby stopping photosynthesis and stunting growth. Canopy temperature can be reduced by up to 8°C using a CGWS program, which in turn reduces overall stress on the tree.
Ultimately a CGWS program provides the opportunity for earlier fruit production which can significantly improve the financial viability of new citrus plantings.
Fortnightly to monthly applications are required and applied to the point of runoff.
When to apply
Begin in late winter through until early Autumn or apply when the weather is consistently over 20 degrees.
Using a small container, slowly mix 50g (3 tbsp) of powder per 1 litre of water while constantly stirring to prevent clotting. Add mixed contents into the sprayer bottle, seal then shake vigorously to ensure contents are mixed thoroughly.
