  1. Nematodes for Box Tree Caterpillars

    Spray with Nemasys Fruit and Vegetable Protection Nematodes to control Box Tree Caterpillars. Box Tree Caterpillars over-winter as caterpillars rather than as moths, so it is essential to kill as many of the caterpillars as possible before the temperatures drop. The caterpillars over-winter, hidden between leaves that have been spun together with silk and will then emerge next spring as moths to reproduce and produce the next generation of caterpillars. To make sure your box plants / trees are free from Box Tree Caterpillars before the winter, spray NOW with Nemasys® Fruit and Vegetable Protection Nematodes. We supply 3 packs, which are applied 3 times at 7 day intervals. Nemasys® F&V works at temperatures above 12°C/40°F, so apply during the growing season i.e. between March and October. Nemasys® F&V TRIPLE Pack - 3 Packs sent together for controlling caterpillars each pack treats 60 sqm.

    N.B. Nemasys F&V needs a temperature of 12°C/40°F and is a perishable product (it will keep for approx 2 weeks in the fridge)so please order when you are ready to apply. Nemasys F&V is available now or to pre-order for delivery later in the year, simply select a future date. As the biggest supplier of nematodes in the UK and because we have fresh deliveries of nematodes each week, you are guaranteed the freshest stock with the longest expiry date available.
