Did I get your attention because I don't know of a silver bullet. If so,educate me.
Insecticide applications are my most dreaded treatment and I do even apply them. My worker does. I would like to reduce chemical use or better yet eliminate it. I can compromise with a few bugs and if my customers complain I can hit them with safari or even crosscheck. My main buggers in 2012 were aphids,lace bugs,white flies,mites,leaf miners and lots of scale.
So are there natural alternatives that are practical. I am not going to buy and release a thousand lady bugs. Or do I have to return to reality and soak em with chemicals.
Maybe if we just change the word "chemical" to a better sounding name it won't seem as bad. This approach is working a lot lately.
