1. How will the frost effect my spraying?
Frost leads to the de-waxing of leaves. This means products which penetrate growing leaves (Chlorotoluron, IPU and others) go directly into the leaf, killing the area. After frosts the plants natural reaction is to produce more wax. Therefore three/five days later the plant has another wax layer. This is true for temperatures in and around 0°C. Frosts of -5°c or below are likely to damage the plant after spraying regardless of wax protection.
