Natural pest control for specialized, open- field crops

The entomopathogenic nematode Steinernema feltiae (contained in the product Capirel) is the natural enemies of many pests including Lepidoptera-, Coleoptera- and Diptera larvae.

Having penetrated their prey, the nematodes release symbiotic bacteria that kill the larva within 48 hours. The nematodes then feed and develop in the same host, but can also parasitize several larvae.

Preparing the mixture:

Empty the contents of the sachets into a bucket containing at least 12 liters of water (temperature: 15-20 °C) Stir and leave the contents to dilute for five minutes. Mix again and pour the contents into the spray tank, filling it halfway. Make up the spray tank with the required amount of water. Continually stir the mixture in the tank (recirculation pump). Spray the mixture immediately after preparation.

Precautions for use:

The soil’s moisture conditions, as well as the conditions of the trees’ scaffold branches and trunks, play an essential role in guaranteeing the product’s effectiveness. Ensure that the orchard remains humid and at a temperature between 10 and 30 °C during the first 24 hours after application. To minimize the negative effects of UV radiation, the product should be applied in the evening, except if night-time temperatures are below 10 °C. The nozzle holes must be at least 0.5 mm wide. To avoid blockages, remove all filters with a mesh size of less than 0.3 mm (50 mesh). Maximum spray pressure: up to 20 bar depending on nozzle type.

Compatible with many crop protection products used separately or together.

Storage:

The nematodes are in a special gel formulation and can be stored up to four months cool (2-6 °C) and dark.

Effective against:

• Codling moth in apples and plums
• Oriental fruit moth
• Summer fruit tortix (Capua)
• Red-belted clearwing
