Caterpillars already in my pepper crops! What should I do?

Fighting spider mites can be challenging, however we have plenty of solutions.

For a curative control, the logical choice is Phytoseiulus-System, using a rate of at least 10 ind./m² and 50 ind./m² in hotspots.

Predatory mites for controlling thrips also feed on spider mites, slowing down population development. Well-established populations are therefore a bonus; particularly Degenerans-System, which is highly heat resistant.

Used preventatively, Amblyseius californicus can deliver good results. In greenhouses with low pest pressure at the end of the previous season, we recommend hanging Californicus-Breeding-System sachets on posts and walls, from where overwintered spider mites emerge.

Conversely, if the pest pressure was high at the end of last season, we advise using A. californicus full field plus Feltiella-SystemFeltiella feeds on spider mites, including red overwintering forms, and is very good at locating outbreaks. We recommend 3-4 weekly applications at a rate of 2-4 pots/ha, equivalent to 0.05-0.01 Feltiella/m², starting 2-3 weeks after planting.

Macrolophus-System can play a key role in summer - for best results, start introductions in spring.
