Koppert Biological Systems offers Spical-Plus, which contains amblyseius californicus, a predatory mite, in slow release bags. Amblyseius californicus is very effective against species of spider mites and several tarsonemid mites. Using the bags results in lower labor costs (compared to manual release) as well as improved preventive capabilities and trouble-free application.
Spical-Plus can be used on a variety of crops including vegetables, ornamentals, fruit, date palms and hops.
