WASHING AWAY POWDERY MILDEW - An instructional video by Jorge Cervantes
NOTE: Admin will move the video from Youtube to the forum for easy access. In the meantime, it has been age-restricted and requires a sign-in to watch it - well worth the effort, lemmetellya.
Recently, my BF and I gratefully watched a video Jorge made about getting rid of the farmer's bane, powdery mildew (PM).
We sent him this PM:
Jorge replied:As a left-over from the summer heat wave here in Cali, a smattering of powdery mildew spread over our Blue Dream OG's that were coming into harvest. Buds untouched, but it was close.
We saw your video just in time and have decided to make the peroxide dip and rinse a standard. Our home smells so fresh and clean, awash with the scent of fresh grapefruit after a spring rain.
We've had many a harvest, but none that smell like this - the fresh and clean part.
Got that? Anybody?The reason that H2O2 works so well is that it kills all the diseases and life on the surface of the plants. With little or no life left on the foliage, decomposition slows and terpenes appear to be preserved. I have not looked into the matter on the molecular level to give a complete scientific explanation. maybe one of the members has more time than I do.I have not looked into the matter on the molecular level to give a complete scientific explanation. maybe one of the members has more time than I do
Powdery mildew can ruin a crop in short order, and can infect your buds destroying their content and making them dangerous to smoke.
This is what it looks like:
On a tomato leaf
On a lilac leaf
On a marijuana leaf
Powdery mildew can be indemic to the plant and can develop as a result of exposure to too high or too low humidity levels coupled with a lack of good air circulation.
It looks like baby powder to the naked eye (hence the name) and under a loupe looks like a matting of extremely small fibers. You can rub it off with your fingers but that doesn't solve the problem. If you touch it with anything - fingers or scissors or a cloth - do NOT touch another plant or anything but the soap and water in your sink.
Sidebar: No, CO2 does not get rid of powdery mildew because of the high heat and humidity levels incurred during CO2 application, and can actually worsen the existing condition. Been there, done that. Yish!
There are a few remedies but the best remedy is to avoid the infection to begin with, and that means sitting up all night moving the fan around the plants if necessary, doing whatever you can to maintain the humidity levels around 40%-50%, spraying with Neem oil every day, washing the leaves with tap water, and the best, KNOW YOUR SOURCE. A good farmer will never sell clones that come from an infected mother plant.
