Just a note of caution on using AVID. It works wonderfully, but Spider Mites are adaptive little devils and the over use of AVID has caused them to build up a resistance to it. In the rose world the exhibitors over sprayed with it so much that they have almost ceased using it. You should spray a rotation of 3 times when you have a serious infestation: one time a week, one time a week, wait 2 weeks and spray one time more. And then you should not spray again unless you see another serious infestation later in the year. You should never spray AVID as a preventative or for something as easily killed by other products as aphids. There are now other miticides on the market, but they are way more expensive then AVID. Considering the cost alone, it's best to save AVID for only serious infestations of spider mites. As a matter of interest AVID was originally developed as a spray for greenhouse growers of Columbines troubled by leaf miners. A side benefit has been it's destructive power on Spider Mites and Adult Thrips. But again, over use has rendered it ineffective for many growers.........Maryl
