there was a sytemic put out by bayer that worked well for me to keep the mites off that had disulfoton and imidacloprid but is now unavailable. they have another similar granular product with imidacloprid but the label does not list mites, while the one with the disulfoton did. i am interested in these because i do not wish to spray and only want to use it as a preventative on potted bamboos. :?:

Alan - Have you tried Avid - a systemic miticide?

Our tech guy says Disulfuton is gone in Canada but worked well when it was available but was never available as a combo with Imidichloprid.. He says with mites preventive spraying is not a good idea because the mites can quickly develop resistance. He instead says use Avid as soon as you see a problem and alternate sprays with Flora-mite or Dyno-mite. Realize we're only talking red and spider mites not bamboo mites but surely the same logic would apply.

yes I have used avid in the past but i live in the city and do not wish to spray. i would rather just do without anything than spray. what i was using before was a granular type systemic that you can just put on the soil for a more times release. i also understand this is not considered as effective by some since the mites do not reside near the vacular part of the leaf; however i have had good success with it (better success in fact than spray).
in the near future i would like to have a garden with mainly p. dulcis, b. fargesii, s. okuboi and p. edulis in order to propagate and disseminate more mite resistant varieties, and eliminate the use of pesticides altogether.

Alan - I wonder if you could use Avid as a soil drench instead of spraying despite the labelling. Don't know if you'd have to alter the dilution rate up or down though. Maybe a call to the producer would make sense.
