Spider mites

The two-spotted spider mite (Tetranychus urticae) multiplies particularly fast in warm and dry surroundings.

Drip-feed fertiliser/irrigation systems and computer climate control produce a dry environment ideal for its development.

They make a network of webs beneath which they prick the plant and lay their eggs.

Chemical control for thrips is suitable for spider mites also, but if it is used intensively then resistance may appear.

Nowadays biological methods of control appear to be an alternative to chemicals that is well worth considering.

This advice sheet is based on the methods used at the SCEA at Montourey (Fréjus, France). These procedures may need some modification to adapt them to other climatic situations. Before starting to grow cyclamen there needs to be a review of precautions against pests and diseases.   We must point out that our advice and suggestions are offered for information purposes and therefore cannot include any guarantee of specific results; it is a good idea to carry out trials beforehand.
