It has been about three months since I walked around and shot every Agave I could find with signs of the mite. A particularly bad A. macroacantha has been my most observed specimen. After only a few weeks, the classic grease marks had dried up and started looking 'dusty' for lack of a better word. The new flush of leaf's on the plant now look pretty good. A little damage, but it isn't greasy. I alternated with sevin at about six weeks, and just hit the plants again with Forbid a week ago. I also noticed for the first time, some mite damage on some one gallon Furcraea roezleii.
I think the waiting period to see if it is really working can be significant if the mite has been down in the crown of the plant. it can take quite a long time for the plant to flush through all the growth. I think another two or three months will tell the whole tale, but general observation is that the specimens are showing really good signs of improvement.
I was putting a drop per gallon of my palmolive surfactant in the solution, as well as using distilled water... would a little DMSO be a consideration?
