Yes, I use a surfactant spreader/sticker in all my sprays, as it makes any spray far more effective as a wetting agent. I use ag oil with a s/s when it is cool enough (below 60 degrees) to avoid leaf damage, and I rotate that with Avid and s/s on my new quarantined plants. Ag oil (and Neem oil) and s/s are both effective against all stages of mites, including mite eggs, which most sprays are not effective against. But they are limited alone because they must come in contact with the mites and eggs to be effective, but they get through or coat the webbing. Also in areas where it freezes, the temps help to kill them off, or at least slow them down between spraying.
Happy trails...

This should have read: Talstar is not a systemic when used against black vine weevil as a soil spray/drench it gave close to 80% control 3 years later, pretty impressive for a pyrethroid. ASomewhere I have the documentation from Rhode Island.


and is now corrected. It has impressive repllent qualities.

Schmu: Which surfactants do you use? Silwet and Sylgard gave very good control but these tests were done with long drenches in petri dishes so take that with a grain of salt, one could never expect suck results spraying.
