Spidermites!

(1/5) > >>

toehead:
I've been battling spidermites for a month or so on my kumquat, and I think I need a change in strategy.


I've been using this product, which is labelled for controlling mites. It doesn't seem to kill them. i've been spraying weekly, with little reduction in number. Yesterday I bagged the tree, completely soaked it  sealed the bag for 24 hours, followed by a high pressure washing of all the leaves.





I still found some live mites under the microscope.






Do you all have any recommendations for products  or techniques that work?

Four years ago I found this: https://www.organicbti.com/product-page/forbid-avid-and-floramite-spider-mite-treatment-program-inc-top-3-miticides

It is a small amount of all the top rated miticides for spider mites, so you can rotate their use to avoid resistance buildup.  I have been using it regularly for years and I still have more than half of each of the original bottles left.  Works great.  I have yet to eradicate spider mites and maybe never will, but these sprays keep them down for a couple months

I paid $80 in 2021, not cheap, but at least the price hasn't gone up since then.

However, if you only have a few small trees I suggest trying dormant oil or soap spray first, as they are cheaper.  I am spraying a garage-sized greenhouse full of large trees.

Spider mites gave me hell in the greenhouse winter before last. This winter I sprayed water with Dawn soap in it on my Citrus and Plumerias and kept the spider mites under control pretty good. I am sure there are things that work much better, but this was no cost, and it helped in my opinion. I am going to try it on my Thomasville trees in the yard this summer. 

1rainman:
The main thing is letting them get rained on, spraying with a hose, or shower. You wont have a problem with regular showers but indoors it may be hard. Neem oil is good though you want to still give the plant an occassional hose down or the oil itself will stay on the leaves and be a problem.

Mabus:
I got something easy you could try. Coffeeine as well as nicotine is an insecticide.

Place a few cigarette stumps in a strong coffee and spray it a day later. Worst case, you wasted a coffee.
