Bamboo Mites

Posted by island_murr (My Page) on

I can't find a way to rid my bamboo of the bamboo spider mite. I have a number of plants so spraying them with oil and soap is daunting. I was told that a chemical called imidacloprid was a good systemic control and although I've applied this chemical a number of times, I still have mites. Other posters on this forum indicate that this chemical is not effective against mites. Who to believe???

I found an Oregon University site which outlines some chemical options and spoke of the chemical AVID. Does anyone know anything about AVID or it's effectiveness? Or any other control?

Any help would be appreciated....

Avid is very effective for controlling bamboo mites. The active chemical is abamectin and the main caution to observe is not to spray it around bees because it can also kill them. I have used it on my large collection of bamboo over the last five years and it takes care of the problem. It's an expensive chemical (I paid $125 for an 8 ounce bottle), but that quantity makes up about 400 gallons of spray mixture, and will last me a number of years. As with any chemical, it's good to only spray when absolutely necessary so you don't end up helping some "super mite" evolve. I spray about once a year, and I mix in some horticultural oil, like Stylet, which helps smother the mites. When you spray, try to hit the underside of the leaves as that is where the webs are. However, abamectin has trans-laminar properties, so it will enter the leaf structure and compensate for not hitting every single surface.
