I have just got spidermites.
I sprayed most of the plants this morning with a spray that contains Fau-Fluvaunate and Myclobutanil.
I have used it before, it works well on spidermites.
The miticide part is the Fau-Fluvaunate, and the Myclobutanil is a fungicide.
I want to get a miticide without the Myclobutanil as apparently it's ok for food crops but not approved for tobacco, as burning it gives off a poison gas.
Myclobutanil is also called Eagle20 in some brands.
Obviously I didn't get all the mites as I had a look tonight and on one plant they were all dead, at least they weren't moving so I assume they are dead, and on another plant they were still moving around.
Have to get another bottle tomorrow and spray the one's that are still alive.
Also saw lots of eggs as well, don't know if I will have to spray them when they hatch.
The plants have not suffered much damage from them so far, so I think the infestation has just started.
