Thanks. How about Bronners instead of dish washing liquid? I have heard that Ivory dish washing liquid is a better choice than say Dawn.
Dish soap works much better than Dr. Bronner. I've tried to make Bronners work a bunch of times for foliage spraying purposes, but it's hard to beat Dawn. I also use a baking soda mixture when I encounter PM.

Edit: keep an eye out for th he fragrance/extra additive free versions, but in a pinch the regular blue dawn has worked fine for me. I don't doubt it makes some growers cringe..

eagle 20 on new clones, keeps me safe during veg and is metabolized out of the plant in 30 days. By the time the plant is finished, that dose is a distant memory

Wrong! bad advice. Sorry I don't call out people often but Eagle 20/myclobutanil has/have no place here. If people want to to risk it themselves then go for it, but don't tell others to follow.

Yes the best thing is fans blowing all the time but not blasting plants. Eagle 20 is the best but it pretty much toxic. Just curious what people here like. I know that Bonide Copper spray is pretty good.
I have used ho2o 3 percent right out of the brown bottle, right up to day of harvest no burning of hairs stops pm in its tracks:bigjoint: but best bet don't get it

Well put

I love how people proclaim these certain time frames, 30 days, 45 days, etc...

Bottom line is no one knows and recent articles out of colorado suggest that it stays around much longer than people think -- it turns to hydrogen cyanide when burned

My opinion is the same for products like avid, floramite, forbid, etc.

I have learned that a strict IPM, even with organic means is the only way to maintain a healthy and clean garden

I have had great success with products like nuke em, green cleaner, organocide, neem oil and others as well -- keep the environmental controls in check, come up with an IPM and never worry about mold, mildew and mites ever again

old news. the move is smart by Colorado state because people are idiots and the state is protecting themselves from liability, which is what that ban is really about. the idiots are the ones who use e20 inappropriately in commercial grows at growth stages they should not. it should only be used on young clones or seedlings.

your own article describes how in tests of chinese tobacco with e20, about 10% was found 21 days after application. the directions on e20 says it lasts for 30 days before needing reapplication, so it makes sense 10% remains at 21 days. using only on clones/seedling as i described, and as is recommended with cannabis, gives them at least 60 days if you flipped the day you dosed them. so, generally, they'll see 70, 80, or even more days because most people dont flip a fresh clone or seedling, which is plenty of time to metabolize the product.
