NinjaMaster Posted September 12, 2019 Share Posted September 12, 2019 Hi Guys, Does anyone know of a Systemic fungicide i can use in Veg to destroy Powder mildew. Im worried it makes my Fem Plants Hermie as ive seen it happen to a friend of mine. I have found a product called Tenazole: https://leroymerlin.co.za/tenazole-100ml-81426273?sfdr_ptcid=32806_617_517030259&sfdr_hash=d21cd6d8f2f1423d3ae32315d9bfa661&gclid=Cj0KCQjw2efrBRD3ARIsAEnt0eiiUSiVnKMtkc6e3HaD5yLdOvqldLp26pTfVGl_UjKnFqS9wbS6CtMaAg4NEALw_wcB Does anyone have Experience with this kind of thing. Ive controlled PM with Baking Soda High PH Water. But id like to kill it this time and not have to control it anymore. Quote Link to comment Share on other sites More sharing options...
PsyCLown Posted September 12, 2019 Share Posted September 12, 2019 What about AQ sf? http://www.agro-organics.co.za/aq-sf/ Never heard of Tenazole. 1 Quote Link to comment Share on other sites More sharing options...
Jimmy-z Posted September 14, 2019 Share Posted September 14, 2019 Try copper soap, it's worked with my last grow & its non-systemic. I've found that baking soda only helps for a short time & the PM eventually comes back if the humidity doesn't drop.Sent from my SM-N950F using Tapatalk 1 1 Quote Link to comment Share on other sites More sharing options...
Kgrows Posted September 14, 2019 Share Posted September 14, 2019 systemic is never a good idea. you need to look at the causes: high humudity - what can you do to drop this below 45%? are you spraying your plants at night? stop, try keep the leaves dry, watch for where they sweat & trim to avoid. Are you growing in a tent? if so & you have had pm continuously, then the spores are more likely all over the tent, so you'd need to sterilise everything, filters, fans, pots, watering systems, every surface, all tools etc & replace all ducting. same thing for an indoor room. outdoors, look at your other plants in the garden, treat them the same way as your cannabis plants. also look for PM resistant strains etc. Once you've done everything you can to kill existing spores then IPM, prevention is better than cure 2 Quote Link to comment Share on other sites More sharing options...

PsyCLown Posted August 17, 2021 Share Posted August 17, 2021 An old thread, I know... Just want to go back to it and provide a bit of extra info. I see this thread pops up high up on the list if you Google for "Tenazole cannabis" Tenazole should not be used on cannabis. Possible side effects if consumed aside, cannabis does not tolerate it well. Stunts the plants, turns the leaves dark green to almost black and leads to stems being discoloured. Alterntiave solutions for PM which I feel work well are as follows: AQ-SF (can be mixed with bio-tricho) Sulphur / Bio-sulphur Coppersoap (not to be used in flower) These solution may require one to do multiple sprays though but is a far better option. There are many other safer things to use to treat PM which are effective as well, instead of using Tenazole. Tenazole also leads to resistant strains of fungus which can become a big issue as time goes on. 3 Quote Link to comment Share on other sites More sharing options...
Marzcanna Posted August 17, 2021 Share Posted August 17, 2021 (edited) You can go out and spend some cash on some good products that do work. But you can also use the cheaper alternative such as Milk thats also works. Alot of us growers make a big issue of something that can easily be fixed with some home remedies. Anther good example is the PH down and ph up solution that i get into fights about with my friends all the time, i use lemon juice...gets my ph where it needs to be and my flowers still come out looking great and I save some cash for things that are a MUST get for my grows Edited August 17, 2021 by Marzcanna 1 Quote Link to comment Share on other sites More sharing options...

I do have a bottle of both ph-up and down but only because im using RES now and i have no choice but to use it to keep the ph longer in the RES. But for normal top feeding, I will still argue to use lemon juice 1 Quote Link to comment Share on other sites More sharing options...
Prom Posted August 17, 2021 Share Posted August 17, 2021 Veg I would always go copper soap, great results and very easy to use. I give them a spray with copper soap to clean up before I move em in the flower tent. At least I know they arrived clean 1 1 Quote Link to comment Share on other sites More sharing options...
TheLazyFisherman Posted August 17, 2021 Share Posted August 17, 2021 I always had issues with PM during winter until the past grow...the solution depends on ur grow area temp and humidity with lights on and lights off?Also something I learnt from this forumSent from my VOG-L09 using Tapatalk Quote Link to comment Share on other sites More sharing options...
