The Borg Hemp Russet Mites

The Borg!
HRM
I had heard a few times of Russet and Broad mites during my growing career, what a nightmare I thought when I heard a grower mention them. and then I made a mistake and they ended up in my garden. The Hemp Russet Mite is a invasive species that eggs are smaller than glandular trichome heads. They are invisible to the naked eye. After death a female can lay 100 eggs. They look like Weed Maggots! I can think of nothing more disgusting and during the course of a month I learned more than I should have to know about this pest. However, I can now pass on what I learned without rumor or bullshit fact as we now show no signs of infestation after I took the steps outlined below. But first how the hell did I get them?
I have always advised never to take in a clone from a grower you don’t know very well and even then, assume it was infested with something. While controversial in the old days as a seed breeder I always dipped my intake clones in Avid, a pesticide that kills just about everything but is systemic meaning it can stay in the plant. Since I produced seeds only for so many years, plants grown from these seeds test negative and it was a good way of making sure rare cuttings could be transferred over. Even now some growers use Avid on clones for flower crops but you must grow the plant out 3 times to a healthy bush and take fresh clones to make sure it doses not test in solvents made from that cutting.
WE NO LONGER USE AVID! That’s right I grow flowers these days and we only use natural or organic products. After the fire I was collecting as many cuts as possible and treating with products like Dr, Zyme and Nukem which are mostly oils and Its unique formula is comprised of 100% food grade ingredients that are commonly found in every day food products like bread! Patrick King has Drank Dr. Zymes before he tells me. But one of the clones I took in was infested with invisible creatures and the person that passed me the clone said “It Should be clean” this was my first mistake trusting someone’s word. Don’t assume anything with a cutting or plant someone gives you assume the worst and save some headaches.
I treated the cuttings and kept them apart from the main garden but starting over I was rushing so I moved the plants into the main area next to my existing plants. Within a few weeks I noticed the plants showing signs of nutrient deficiency and an overall loss of vigor. Thinking we had made mistakes mixing Super Soil we started feeding the plants with Dragonfly Earth Nutrients even though the plants should not have needed anything. The garden just didn’t look right and we treated for fungus gnats with sand hoping this was the problem, the gnats went away and the plants still looked poorly. I was filming one day and a viewer named St. Bernards Observation Booth said looks like Russets to me Sub. The new growth was deformed and gnarled I assumed over watered. I though no way I have those things and decided to order a 1000x USB scope and see for sure. I was positive he was wrong and other friends said the same thing. I was shocked when under the microscope I saw hundreds of crawling maggot like creatures on all my budding plants. INFESTED!!

Some people think that the DEA created this super bud to eradicate Cannabis but it was placed along roadsides in thee major area’s in the US to control invasive weeds. Before everyone grew there was no way for them to get into gardens now with Medical and recreational growing so many people have gardens that these these bugs have a new habitat, your Plants!
What are Hemp Russet Mites? First off, they are Tiny about 0.2 mm much smaller than a spider mite. Its scientific name is Aculos Cannabicola and have a pale beige body. The adults lay 10 to 50 eggs Inside of the plant! Yes INSIDE this make them very hard to get rid of using normal methods. They feed on Resin during flowering and are extremely hard to kill even with direct contact with Nukem and Venerate. They inject your plant with a toxic to weaken its defenses this is what you start to see there literally making it sick. Being so small even a veteran grower can miss them, I had a helper here and he was clueless I was infested even thinking they came in after he stopped helping but they came in on that one clone. You could see the spread from that area once I knew aliens had invaded my garden.

So How the hell do you kill them without using pesticides?
This first part is the hardest and one you probably like me will hesitate to do at first. You have to kill off your flowering plants! The number one tool in the fight is Micronized Wettable Sulfer and you simply cant spray this on flowering plants and process the flowers in anyway. We tried treating the plants in Flower with the following before killing 40 full grown plants
Dr Zymes
Nukem Flying Skull
PFR_97
Venerate
10000 PPM Co2
122 Degree Leaf Temps for 2 hours
They were still alive and it was at that point we knew we had lost all the work to fill the flower room. All plants were bagged and pulled out of the room all pots and soil and everything was taken directly to the dump. The room and yard were treated with avid, then washed with simple green and then again washed with bleach and then once again simple green. All reflectors, walls, cords were wiped off, the floor was torn open and treated and washed 4x.
Even the ceilings were scrubbed down.
Make sure to wear a protective suit and respirator during all of this.
All plants in flowering were killed and all plants in veg were treated with Micronized wettable sulfur, 3 times over 2 days then all plants treated with Nukem and clones taken. The USB scope is used daily to inspect new growth and old insuring nothing is alive and no eggs are present. Plants are now treated with an IPM regiment of Sulfur on Monday and Nukem on Fridays insuring all plants are clean before entering the flower room.
Killing flowering plants that patients may be depending on is the tough part. You can’t use anything that will kill them once there in flower that doesn’t ruin the taste of the end product plus your buds are already infested with weed maggots. I would not share the flowers from my garden or even press them I donated them to someone who made creams and such.
Someone told me when I got russets that I would have to move and I thought I might for awhile but so far so good and you can follow our fight on Instagram @subcool420 I check for anything with the scope live so others can learn from what I learned and my mistake.
Know where your clones come from and assume the worst if you don’t you may be assimilated by “The Borg”

This is Part 1 After all of this I actually made a huge mistake and I did not toss my bamboo stakes and some of the soil I had on my property. After a successful harvest my russets started spreading again and I know believe even tougher methods are needed to clean a infested rom without chemicals or toxins.

Stay Tunned

Someone reported success with cold water to remove mites and sulfur dust to kill the larvae. I don’t think his was the mite you specify here. Sulfur dust might be fine for someone with an applicator and training but not in living spaces.

How did you apply this? Wet? did you also rinse?

Choose the type of sulfur you need for the pesticide. For example, lime sulfur is safe to use in conjunction with oil spray but elemental sulfur is not and you must wait at least a month after applying the oil before you can use the sulfur spray treatment. Lime sulfur is generally the better choice between the two.

You used which type sulfur?

I successfully eliminated HRM in my garden using nothing but horticultural oil in a fogger. I used JMS Stylet oil, but I’m sure any brand would work. Hort oil kills them on contact, the tricky bit is coverage (hence the fogger).

Fog every three days for a couple months including all surfaces and you’ll never see them again.

DO NOT use ANY oils (including horticultural oil) if you have used any sulfur containing products within the past couple weeks. Sulfur + oil will burn the shit out of your plants.

At what rate was this used? I’ve used that product outdoors the last couple of years myself.

WE used a wetting agent I made a crucial mistake by seasing sulfer and depending on predators in my damp clone bin.

Wow. I hope to never have those. Now I am really gonna be careful if I even take in clones after reading this.
How wide spread is this?

The moral of the story, don’t bring clones into your safe and clean grow unless you’re absolutely certain they are as well. Thanks for sharing SC.

I have never seen these little Bastards before…

I have seen some pretty evil looking red mites, though, that drank Avid for breakfast daily in a buddy’s closet haha.
These sound even worse…I will remember this info, hopefully I won’t need it ever…
Thank you for your time, there’s a lot of useful info here.

I use JMS @ 14ml per liter or 60ml per gallon.
