As a commercial grower, it’s devastating – you walk into your flowering room in the late grow season, and as you’re inspecting your cannabis crop, you find that powdery mildew has taken hold of a group of plants. It’s a worst-case scenario come to life. And, unfortunately it means the affected plants likely need to be processed into extract or outright destroyed. Stopping a powdery mildew infection is hard – but preventing infection can be so much easier with one simple tool. Here’s what to do when you find powdery mildew, or PM, on your cannabis plants in the late flowering stage.
Neutralize the Infected Plant
Unfortunately, it’s time to quarantine. The infected plant and the plants surrounding it should be very carefully taken out of your grow space. Disturbing the plant in any way could cause PM spores to come off and float to adjacent plants, but there’s one trick to limiting this risk.
Carefully wrapping infected leaves or plants in plastic bags for transport should limit the ability of the sporing mildew to spread as the plant is picked up and moved to a safer area. Once the plants are separated it’s up to you whether to trim the infected leaves and send it for processing or to destroy it altogether. But, for many commercial growers, it may not be worth it to douse a PM-infected plant with chemicals at this stage and hope that it becomes usable as-is. After you’ve removed the plants from this separate area – clean thoroughly to be sure no spores remain behind.
One thing to note – powdery mildew spreads fast. If you smell decay throughout your flowering room, or if you see multiple plants with significant powdery mildew infections, it may well be that this crop is at risk of becoming unusable. This is the absolute worst case – but it can be prevented with a straightforward solution. Something that kills powdery mildew before it ever reaches your plants.
