Crop Guard Dust Off PM – Powdery Mildew Foliar Spray

Deal with white powdery spots in one treatment

Dust Off PM is a 250ml concentrate for growers dealing with the white powdery spots and clumps that appear on leaves and stems and spread across a plant alarmingly fast. It is mixed at 20ml per litre and applied as a foliar spray, and it works on plants grown in any substrate and any grow system. Used as a preventative it goes on every 14 days from first planting until two weeks before harvest; used as a rescue treatment it is there for when your normal preventative routine has been missed or overwhelmed.

Key Benefits

• Highly concentrated - 250ml of concentrate makes a large volume of spray at 20ml per litre.
• Works in any system - suitable for plants in any substrate and any grow system.
• Preventative or curative - use on a 14 day cycle to stay ahead, or when a problem has already taken hold.
• Usable late in the cycle - can be applied up to two weeks before harvest.

How Powdery Mildew Gets a Foothold

Powdery mildew thrives in still, humid air and on a crowded canopy where leaves stay damp and airflow cannot reach the lower growth. A few spots on one leaf become a dusted plant within days, and by then you are treating rather than preventing. Fixing airflow and humidity is the long game, but a foliar treatment on a regular schedule is what keeps spores from establishing while you sort the environment out.

How to Use

• Shake the bottle well before use.
• Add to water at 20ml per litre and mix thoroughly.
• Apply with a spray gun set to fine, covering tops and undersides of leaves and stems evenly.
• Spray only in low light, ideally just after the grow lamp goes out, to avoid leaf burn.
• Repeat every 14 days from first planting until two weeks before harvest.
