Like many others I first mistook the russet mite damage as a pH, nute, virus, or soil problem. I had it narrowed down to a boron deficiency. Nope. Hemp Russet Mites. For sure. No doubt. Saw them crawling and the smooth eggs, not the dotted ones like the Broad Mites lay.
I have spent the last couple days reading up on these evil little bastards and my brain is a bit tired but I have a couple questions I seem to have not found the answers to.
1. I reuse my soil. I had some issues and had to stash my grow in a travel trailer in a field for a few months and was not able to take care of them like usual. I reused some soil a few times without the proper treatment it usually gets. Now I can treat my soil well again. Question is: Can these little bastards survive in the soil, in any form, when the soil is being flushed heavily with 120+ F water?
2. I keep reading about people using Avid and Forbid to take them out but I don't want to use that strong of stuff. I am reading that Azamax and Neem Oil do not work on these mites. Question: Why not? There is the smothering them to death function of Neem and it's an ovicide so I wonder why that does not kill them? Shouldn't heavy foliar application every three days for 15 days do the trick and if not, why not?
3. I have learned that the Broad Mites inject a toxin that messes up the growth even after the mites are dead. The damage pics I've looked at seem similar for both Broads and Russets. Question: Is there long lasting damage from the Russets or will the plant return to normal after getting past all the stress?
4. Aspirin at 325mg a gallon in the soil feed and 150mg a gallon for foliar is being used to stimulate the plant's immune system to assist in getting through the terrible stress these infestations are putting on the plants. Question: How often can a plant be watered and sprayed with aspirin before it starts to cause a new problem?
Thanks in advance for taking the time to help me out. Peace and Good Health.
