It's exactly what it is lol that's the thing people need to understand about the ban list as of now. It's just thrown together I mean honestly they just said certain shit can't be used. Marked green cure banned for whatever reason. They don't know what they're doing yet

Horse tail is excellent. Works better if you start early though... The potassium bicarbonate (Green whatever) and the calcium carbonate (hi pH) kill. Horse tail is a natural form of silica.

I know OR just banned a whole shit load of common/popular MJ bug/fungus preventives & nutes with special sauce (Rock Resinator being one )
that could not be used at all on MJ 4 sale or med MJ
that means a state wide ban on the sales of these products too is coming down the pike

Oh ya I mean I get the paclo ban 100% shits horrible that being said them banning shit without doing any testing is retarded. If they could tell us about these chemicals we could know some real shit. What lab is good for something like this?

a University , anyone else has a vested interest if they do the funding
found this looking @ paclo search

I wonder what's in Rock Resinator ? I got 1/2 a jug left from over from last years gro
didn't know there was a issue

I agree, this was a situation however that unfortunately I was forced to use a chemical responsibly, the first time in all my years of growing. White I listed exactly what happened and the steps I have taken in this thread , but to refresh:
I tried every organic solution under the sun, I am and always have been an organic grower. Organic solutions include 9:1 skim milk, baking soda, neem oil, sm90, ect.. These plants are in beautiful shape, and it they weren't so healthy the entire greenhouse would be covered. We are talking 5-10 leaves with PM per plant on 10-12ft tall bushes. The problem is under control, just not eradicated. And since the plants are so healthy, they are doing an excellent job fighting it off.
The main problem is my property has a lot of wild plants with PM on them this year (I live in the mountains). Colorado received a lot of extra moisture this year, which I think contributed to this. My plants are also significantly larger, which led me to increase air flow and defoliate to reduce humidity (Colorado is a rather dry climate). Environment is as perfect as possible given the conditions.
Regarding your point about half life, that was my mistake, you are correct. However, I used a minimal dose and I am 65-75 days minimum away from harvest. Also the study of this pesticide used on tobacco stated 90% was gone within 21 days, so my initial report was incorrect.
Bottom line is this:
As I said, I am getting the plants tested at the conclusion of this harvest. I would rather attempt to save the plants then kill the whole crop. Please also see the studies I linked at the bottom of page 5, including an individual who used this product and got it tested. I also know people in my growing circle who have used this and tested with zero trace at harvest.
I used full strength (2tbsp a gallon) on Friday and I still found some spots in the greenhouse today. I will probably apply again tomorrow and update with results.
Did you notice any negative affects on the buds (brown pistils, lack of smell, ect.?). the plants will be flowering soon and I don't want to damage the buds if I can avoid it.
I might add this to my arsenal, thank you for the heads up.
I replied to your comment right after your post numb nuts and I also addressed your post again at the bottom of page 5.
I promise my ganja is way cleaner then yours, that's not even up for debate.

Which the lawsuit failed.. Please educate yourself before commenting. The scale and amount of toxins used by corporate dispensaries is sickening, comparing that to my organic garden where I used a fraction of the recommended amount and its the first chemical I have ever used is laughable.It is funny ppl use this and a dispensary was getting sued for the use of it

U are laughable, said they got sued, never said they won. U seem to be over defensive, I didn't refer to u personally.
Regardless, the closest thing to marijuana when it comes to crops is tobacco which eagle20 has not been approved for.... unless u live in China

Plenty of things are approved for by the corrupt EPA, FDA, all the other alphabet soups.. doesn't mean it is safe
ill trust my own lab tests aka research over your loud ass opinions. Don't post in the thread if you don't have anything to contribute, like I said in the original post

You got to do what you got to do just remember that eagle 20 last a lot longer than thirty days. It has a 30 day half life. The study I posted suggest it is longer than 30 days.
Lets say that your initial treatment puts it a 100,000 ppm. That figure is just an example. With a 30 day half life at 30 days there would be 50,000 ppm. After another 30 days it would be 25,000 ppm. Another 30 days it would be 12,500 ppm. another 30 days it would be 6,250 ppm. Another 30 days and it would be 3,125 ppm. That is how half life works. At 150 day it would be 3,125 ppm. That is a long time.
On top of that, one of the chemicals in eagle 20 creates hydrogen cyanide when burned. It is some nasty stuff.
Just don't listen to some stoners, read the msds and the study I provided. You smoke cannabis, which is different than eating something.
I have the same problem. It stays in the 90's during flower here with very humid conditions.
Grow sativa dominant strains. they handle it better. Stocky thick indicas tend to get pm and rot. Do some selective pruning to improve air flow.
Its nothing against you, I just want people to know what they are using.
I would be very pissed if I found out someone was using eagle 20 on bud they sold me. Its why I grow my own, that and I don't want to support cartels. Who knows what they use on them.
Good luck and I hope you beat the pm.

@High_Haze Can you get a copy of the test from the people in your circle? If not when you test yours I would like to see the results.

Eagle 20 and Myclobutanil in the Context of Cannabis Cultivation and Consumption
5/14/2015
4 Comments
Overview
On March 23rd, several Denver-based marijuana grow operations were ordered to quarantine plants after it was determined they were treated with Eagle 20, a fungicidal pesticide (1). Myclobutanil-based fungicides, including Eagle 20, are applied to a wide range of edible agricultural products (grapes, apples, spinach, etc). When applied correctly, myclobutanil is known to have low toxicity to humans. Myclobutanil-based fungicides, including Eagle 20EW, are not currently approved for use in the United States on tobacco, the only (other than marijuana) smokable agricultural commodity. The toxicity and health effects of myclobutanil in the context of combustion/inhalation (versus ingestion) have not been assessed.
The following analysis summarizes some of the known chemical and physical properties of myclobutanil, and highlights the potential health implications of using this chemical on marijuana.
Mode of Action
Myclobutanil is the active ingredient in several brands of pesticides, including Eagle 20EW. Myclobutanil works by blocking a key enzyme involved in fungal cell membrane synthesis, leading to abnormal cell growth and eventual death of the fungal pathogen (2) Myclobutanil is a systemic fungicide, meaning it is absorbed at the site of application (ex. leaf) and distributed throughout the rest of the plant, thereby providing more comprehensive protection from fungal infection (2). As a systemic chemical, myclobutanil cannot be removed by washing treated crops, although residue will decrease in plant tissues over time. The final remaining residue levels vary considerably and are highly dependent on the rate of application, the time of last application before harvest, and how well the specific plant clears the chemical from its system.
Myclobutanil Tolerance Levels
The Environmental Protection Agency is responsible for regulating the pesticides used by growers to protect crops and for setting limits on the amount of pesticides that may remain in or on foods marketed in the USA. These limits on pesticides left on foods are called "tolerances" in the U.S (3).
The EPA establishes tolerances or each pesticide based on the potential risks to human health posed by that pesticide, using actual or estimated residue data, as well non-human toxicity studies, to reflect real-world exposure as closely as possible (3).
Tolerance levels for myclobutanil were established for exposure via inhalation, absorption through the skin during pesticide application to crops, and ingestion of agricultural commodities treated with myclobutanil. Myclobutanil absorbed by the most common route, dietary exposure, is metabolized by gut enzymes and the liver prior to entering the bloodstream (4,5). Myclobutanil absorbed via inhalation enters the bloodstream directly via the lungs.
I. The human health effects from the combustion and inhalation of myclobutanil have not been evaluated
Tolerance levels and toxicity studies for myclobutanil on edible products should not be used for evaluating the safety of myclobutanil on marijuana. Passage of pesticides into the bloodstream varies considerably between inhalation and ingestion routes of exposure, and the application of high temperature is known to alter the chemical composition of myclobutanil. Unfortunately, very little information is available to evaluate myclobutanil in the context of tobacco use, as Eagle 20 and myclobutanil-based fungicides are not approved for use on tobacco plants in the United States (6,7). Myclobutanil is approved for use on tobacco cultivated in China, however, and a 2012 study has demonstrated that 10% or more of the active pesticide remains on tobacco leaves up to 21 days after treatment, with residue present from 0.85 parts per million (ppm) up to 3.27 ppm (
. Using tobacco as a model for pesticide retention, it is probable a considerable amount of myclobutanil may remain present in cannabis weeks after fungicide application. II. Inhalation of pyrolized myclobutanil residue could expose cannabis users to hydrogen cyanide
As noted on the Eagle 20 material safety data sheet(3), myclobutanil is stable at room temperature, but releases highly toxic gas if heated past its boiling point of 205°C (401°F) (3, 9). Disposable butane lighters, commonly used to ignite marijuana during consumption, produce temperatures in excess of 450°C.
Of course yours is cleaner,

Thanks man I appreciate it.
Yea unfortunately its not just the cartels, its every big time dispensary across the nation besides a select few.
I will post the results here so we can shine some light on the conflicting reports.

@dbkick same information I posted on page 5..

Like I said I still have 65-75 days minimum, I think I will make it, especially considering I am outdoors
