I do believe it's abamectin. Which I've used on figs and stone fruit. But this year I'm just using water. A high pressure stream spraying the trees down twice a week. Spider mites like warm, dry, dusty conditions. Millet in the citrus section says the water spray has always taken care of his spider mites on citrus in a greenhouse.
Interestingly I've never had a spider mite problem outdoors in dry dusty west Texas. But in the greenhouse, it's always an issue from about April through October.
