Steinernema carpocapsae

Effective against caterpillars and beetle larvae

The product


What does CAPSANEM look like?

The product CAPSANEM contains insect parasitic nematodes in the third larval stage. The nematodes are 0.5-0.6 mm long and not visible with the naked eye. Other stages beside the third larval stage develop in the host. The nematodes are packed in a gel that is easily soluble in water.

How does CAPSANEM work?

The third larval stage of the nematodes actively searches for and penetrates the prey. The nematodes feed on the contents of the prey, releasing specific bacteria from the intestinal tract of the nematodes. These bacteria convert host tissue into products that are easily absorbed by the nematodes. The affected larvae die within days. The population development of the nematodes in the soil mainly depends on the soil conditions, temperature and humidity. The amount of nematodes in the soil can only increase if sufficient hosts are present.

When can CAPSANEM be applied?

CAPSANEM is active against larvae of various pests from the order of Coleoptera (beetles) and Orthoptera (e.g. European mole cricket). The product is used in greenhouses and indoor plantings against caterpillars of the families Noctuidae (night owls) and Pyralidae (including Duponchelia fovealis), larvae of Tipulidae (crane flies) and larvae of the great pine beetle (Hylobius abietis). CAPSANEM is best applied at the end of the day because the nematodes are sensitive to high temperature, UV and drought. Keep the soil moist for up to two weeks after initial application. Be aware of repeated introductions. The product is sensitive to various chemical crop protection agents. Ask advice for deployment strategy.
