NOVA 40W fungicide-For safe elimination of Powdery Mildew

Has anyone used this product made by Dow Chemicals??

I have been told it is safe to use on consumable plants such as Marijuana. It is a systemic that last up to 3 weeks and can be applied 2-3 weeks before harvest. I'm just wondering what the community has to say about it.

-Has anyone used this product?
-What are your experiences and recommendations?
-Where can "Nova" be purchased?
-what is the price?

It would be great to find a safe product for removal of PM...Thx in advance.

Peace...B

In my experience, depending where you got the mildew from, the mildew becomes resistant to nova and is less effective each time. I don't think I would be smoking anything spray with nova to be honest, I don't even like eating food that has been sprayed with it. I have used it in the past for mildew on commercial vegetable crops but for me, the most effective is microscopic sulfur spray or lump sulfur in a burner, both of which I woudlnt recommend for cannabis in a flowering stage, but in a mother stage and possibly in vegetative stage. There are two products I enjoy to use when neccessary which are potassium bicarbonate (850 grammes an acre) which translate to .35 grammes per plant in relation to a mature cucumber plant in umbrella style, but I would tank mix with serenade at first signs of infection and every 7 -10 days following, it will suppress but not kill mildew and botrytis, fursarium and other water molds. I don't know if these are safe to use on flowering plants to smoke or not so I am not recommending them but I think they are much more effective than nova if used properly. Actinovate is registered for use of mildew and botrytis supression in cannabis in canada but I have not seen the label on how to apply it. If spraying in flowering for plants you are smoking be very careful with what and how you apply it, I do not know how these products affect things on cannabis specifically, nor how they would break down and what residual affect would be left for smoking. I would say to have clean stock go into your flowering room and resistant strains to mildew would help in the long run although it may not help you out today.

Personally only time I would use it is in veg and never in flower. Pesticides on food crops can be washed off or gone after peeling the skin. Can't do that with cannabis.

Have any of you guys tried UV lights for powdery mildew control? I think am going to buy the "Clean Light Pro" soon. They look pretty effective, there is a couple videos online.

I think UV light would be a great solution for flowering plants with powdery mildew, and it should help with any bud rot as well. However, I have never tried the UV route myself yet, so I can't say it really works 100%!

Let me know if anyone has had any experiences with them, especially these " Clean Light" units. Thanks and death to PM

Bud Rot ....I prefer to defend my crop with regular foilar sprays of neem oil, and assault the mold with a bucket of warm water with 10% bleach ....invert plant(put in trash bag first to contain soils) and dip in the warm water mix hold to 10 seconds then place in a warm windy spot for 30 minutes or so, ...it knocks the poop outta any mold


good luck

It's the same as Eagle 20, only 2x as strong. Same active ingredient. It is very commonly used by many. I do not use it. I find I never have problems with PM if I spray proactively with silicate, aloe and neem.

You can also use compost tea sprays to help prevent it as well. Keep the surface of the leaf covered in bacteria and no mold can get in - buds too.

Since this this one is systemic I doubt that washing it off will get rid of it. That said, it's tested for safety in eating. And it's probably not really that safe since it's likely most testing was done by Dow themselves.

It's never been tested for smoking.

the neem thing is an interesting point.

i know most people just use in veg, but have there been any studies? via foliar application, via soil drench, in flower, or veg?

ive heard all kinds of things, is there any documentation on this?

links please?

thx

Thanks everyone...

Nova is a systemic...which means it(kinda) becomes part of the plant and attacks from within the plant. But it only has a shelf life of 2-3 weeks max after its applied, the plant must be resprayed for it to be once again strong enough to work longer. If Nova breaks down enough in 3 weeks to become useless, it will continue to break down as long as the plant is alive and growing. Common sense would dictate that the residual effects would be very lite, if any, in new growth, the larger and more harmful residuals would be in the older growth of any treated plant.

IMO...The Veg time would be the deciding factor of whether it can be safely used or not.

If your doing table tops and your Veg time is 10-14 days, then it would be unwise to use it because it needs 3 weeks minimum to dissipate and would remain active into the flower/fruit stage contaminating the bud. But if your Veg time is 6-8 weeks or more, because your growing large plants, then I would think it would be reasonably safe to use in the early Veg stage, as long as it has 3 plus weeks to dissipate, it would have the needed time to degrade before the flower/fruit stage is started.

I will need to do more research on this product...But I will say I'm on the fence with Nova, leaning towards its use. From what I have read here and what I could find on the Net...IMO...it may or may not be harmful depending on the time needed to harvest a matured crop, but fungus, mildew and mold are harmful without a doubt. It has been around and used commercially on the general public's consumables since 2001, with a government approval.


Here is a couple links to pdf pages.

Nova Fungicide Canadian label:

http://www.agf.gov.bc.ca/pesticides/nova-label.pdf

http://msds.plantprod.com/document/20372/en/Label

I haven't read, but I've printed these pages and I will read them soon as I find the time.

Thanks again,
Peace...B

I don't have any links. I was in some cannabinoid syndrome thread and every one basically debunked it as contaminated products and poor diet routines. A lot of people in the thread said they were having these symptoms. Then they stopped using avid neem eagle shit like that and it went away. All I know is dispensary weed makes me sicker and my weed (pm,mite,spray free) makes me feel better. I only use things like wizards brew. Its a safe soap mixed with naturely repelant extracts. If it works for you then by all means. Especially in a large setting. But its not for me

Google "myclobutanil halflife", the numbers thrown about here are overly optimistic. Of particular note is the reference to the degradation of myclobutanil resembling a hockey stick when imposed on a graph. To put it simply, degradation after the halflife is met takes substantially longer, slowing to a crawl.

That's the thing just because the 1/2 life is 3 weeks doesn't mean its all gone after 3 weeks. Only 50% of it broke down the rest could be WAY longer.

h202 is the *safest way to eliminate PM... maybe not the strongest but, pretty damn good when mixed into ICE cold water. i often see PM getting "frozen" and then getting knocked off leaves when i spray, like a liquid nitrogen spray for warts on people LOL
