Broad Mites

Posted by No-Till Punk | Nov 27, 2018 | Grower Questions | 7 |

hey Dudeman Brothers!

help!!

I believe I Have broad mites and or russet mites. I plan on culling everything but don’t know what to do about the soil. Do I have to toss all my soil as well???

I’m up here in Vancouver and don’t have access to any good remedies like down in the US like green clean.

Thanks!!!!

Drive south and shop. Blaine is beautiful this time of year.

Wettable sulfur must be available up there though. Suncor and Agrium both produce agricultural sulfur which is effective against HRM.

This is going to be on Growtalk EP 748 this weekend FYI!

This is just an idea and may not be the most frugal, but I would release Lady Bugs until they(the lady bugs) thin out population wise, then add another mulch layer of straw and then release some hypoaspis miles. All the while spraying a good neem product. DGC!

Probably best to ditch the soil. You might be able to apply a bunch of soil predators and then reuse it, but unless you are talking about a huge facility full of soil its probably going to be a ton cheaper and easier to just ditch the soil and start fresh.

When I had similar issues, I shut down the grow, ditched everything and cleaned my rooms really good. Then when i started back up, I was doing preventive sprays with neem every 3 days for the first month and then I released a bunch of swirskii predator mites right before i went into flower. Might have been overkill, but I havent had issues since so it seems like it worked.

If it is possible to burn sulfur in your room, I would. It does a great job for killing mites, but it can be a nasty endeavor. If you pull down your crop, then clean the room best you can, then burn sulfur, then you can decide if it is worth tossing the soil (easiest way to be sure to get everything out). If you choose to try and keep the soil, I would plant a good cover crop like clover and then wait for it to sprout and grow. Once your cover crop is starting to fill in, then order those predator bugs (Soup recommended a good one, swirskii). The neem treatment mentioned by Soup is also a great organic treatment if you can get your hands on it. I know Canada treats neem weirdly. Keep a sharp eye on your cover crop, it often can act as a first alert to pest issues before they make it to your cannabis. Good luck!

Thanks for all the tips! I had released hypo miles and cucumeris a while ago but didn’t seem to help. Also I spray with method 1 and insecticide soap but not enough I guess. I am moving to a new location where I am building a room so no more tents and I would hate to bring these bugs with me. Am going to 4×8 beds so am afraid to bring the soil with me and infect hundreds of gallons of new soil. don’t even know if I can wash the fabric pots in a bleach solution and reuse them. I’ve never had a battle like this. I did grab some powdered sulphur and a high powered microscope but I do think I will have to clean house. The one time I get clones in over a decade and this is what happens. Lol. Wouldnt hurt so much if I wasn’t no till.

Thanks again guys!
I got a crap load of soil to build!
