Capirel

Preparation

• Remove the sachets from the box and keep them at room temperature for 30 minutes
• Empty the contents of the sachets into a bucket containing at least 2 litres of water per sachet (water temperature: 15-20°C/59-68°F)
• Stir well and leave the contents to soak for five minutes
• Stir again and pour the contents of the bucket into the half-filled spray tank (except when tank mixing with a compatible product)
• Maintain agitation of mixture in the tank (e.g. with a recirculation pump)
• Fill the spray tank with the required amount of water
• If tank mixing with a compatible product, add Capirel at the end to a fully filled tank
• Apply directly after preparation of spray solution

Dosage

Capirel is typically applied at a rate of 1.5 billion nematodes per hectare (0.6 billion/acre). For orchard pests use 1,000 to 1,500 litres of water per hectare (100 to 160 gallons/acre). For common asparagus beetle use 500 litres of mixture per hectare (54 gallons/acre).

Timing

Timing and frequency depend on the pest species and the crop environment (relative humidity, soil moisture and temperature). Consult a Koppert advisor or a recognised distributor of Koppert products for advice on the best strategy for your situation.

Environmental conditions

• Steinernema feltiae is active between 10-31°C/50-88°F but performs best at temperatures between 14-26°C/57-79°F
• Soil or air temperature below 5°C/41°F and above 35°C/95°F can be lethal
• Nematodes are susceptible to ultraviolet light (UV): do not use them in direct sunlight
• The moisture content of the soil must be kept high for several days after application. When possible, irrigate the crop before and right after application
• For foliar application, spray Capirel when relative humidity will exceed 75% for several hours after the treatment
• Adding an adjuvant and/or an anti-desiccant/humectant can be beneficial. Ask your Koppert representative/distributor for more information
• Spray in the evening (or morning in some cases) allowing nematodes to work for several hours within the optimal range of temperature and humidity, as described above

Side Effects & Compatibility

• Pesticides can have (in)direct effects on biological solutions
• As a general rule for tank mixing, always add the nematodes to a fully filled tank containing the compatible product
• The product is safe for most beneficial insects and mites, but can have some effect on a few when in direct contact with foliar applied nematodes

Check the Koppert side effects database or contact your local representative for advice.
