I apologize for mean words. I just hate it when I feel the ignorance in the air mainly because your too scared to change your ways. Your leaning towards your false opinion a lot more because you don't want to accept change that could be tedious.
I've only see one thing work. A user named mark6699331 in this thread, https://www.icmag.com/ic/showthread.php?t=43220&highlight=zone+penetrator&page=2, talks about his use of Dutch Master Zone and Penatrator to solve this problem.
I have to say it is the only thing that worked. Make a garbage can of this solution, put your entire plant upside down in it. It is the only thing I know of that goes into your leaves and kills this shit. It is the only thing that ever got rid of PM for me forever.
saw that you used the e20, how did your plants turn out? i used it before my switch to bloom and went 60 days no pm. the nugs are beautiful but how about the smoke safety? you still alive? if u be a caregiver how has everything turned out for you? have you ever gotten your stuff tested?Disinfecting a grow room once a week goes along way in an overall IPM strategy and reduces foreign spore load substantially.
PM spores are everywhere outside when they are in season. However in a totally sealed environmentally controlled indoor grow environment YOU are the only vector and source of infection entering your room from the outside world.
I will agree with you on the usage of E20. However looking at your math in the 1 mL per gallon of e20 only 20% of that mL is myclobutanil. The rest are the solvents used to help penetrate the cuticle. So the residual will be even less than you are calculating.
I'm about to hit my plants going into bloom and 1st time eagle20 user.
is eagle 20 a transfoliate?
or do you have to spray both sides of the leaves?
Not sure what a transfoliate is...
Dont have to spray under the leaves. Spray every leaf surface you can. I find that if I missed a spot, thats where the PM will be...
