Practical tips for controlling spider mites
Spider mites are tiny, but a heavy infestation can weaken plants quickly, especially in hot, dry conditions and in greenhouses.
Spot them early
- Look for fine yellow speckles on the upper side of leaves.
- Turn leaves over: mites and fine webbing sit on the underside.
- Check the edges of the field and the plants near paths first.
Control them well
An acaricide such as Biestictine 1.8% EC (abamectin) controls spider mites and broad mites. For the best result, cover the underside of the leaves well and use the rate on the label.
Keep it working
Rotate between products with different modes of action, and respect the pre-harvest interval on the label.
