Pests

Beetles (Coleoptera):

  • Weevils (Curculionidae): Citrus root weevil (Diaprepes abbreviatus); Blue green weevil (Pachnaeus spp.); Black vine weevil (Otiorhynchus sulcatus) and other Otiorhynchus spp.; South American fruit tree weevil (Naupactus xanthographus)
  • White grubs (Scarabaeidae) mainly from the following species (not exhaustive): European chafer (Amphimallon majale); Summer chafer/June beetle (Amphimallon solstitialis); Amphimallon aestivus; Dune chafer (Anomala dubia); Oriental beetle (Anomala orientalis) Anoxia villosa; Dung beetles (Aphodius spp.); Asiatic garden beetle (Autoserica castanea); Hoplia spp.; Common cockchafer (Melolontha melolontha); Common garden chafer (Phyllopertha horticola); Phyllophaga spp.; Japanese beetle (Popillia japonica); Brown chafer (Serica brunnea)
  • Wireworms/click beetles (Agriotes spp.)
  • Flea beetles (Phyllotreta spp.)

Caterpillars (Lepidoptera):

How it works

How it works

Mode of action

The nematodes enter the pest and release symbiotic bacteria into the pest's body cavity. These bacteria convert the host tissue into a food source, on which nematodes feed, develop, and reproduce inside the host. This kills the pest within a few hours to days after infection.

Visual effect

Infected pest insects in the root zone turn red to brown but may be difficult to find, due to rapid degradation.

Directions for use

Directions for use

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 six litres (1.5 gallons) 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 compatible products)
  • 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 Capyphor at the end to a fully-filled tank
  • Apply directly after preparation of the spray solution

Application

  • Nematodes can be applied using a watering can, an airblast sprayer, through a sprinkler system, with a backpack sprayer, or a vehicle-mounted spray unit
  • To avoid blockage, all filters should be removed, especially if finer than 0.3 mm (50 mesh)
  • Use a maximum pressure of 20 bar/290 psi (on nozzle)
  • The spray nozzle opening should be at least 0.5 mm (500 microns – 35 mesh) - preferably high flow rate cone nozzle types
  • Continuous mixing should take place to prevent nematodes sinking to the bottom of the spray tank
  • Avoid sprayers equipped with centrifugal or piston pumps
  • Water tank temperature must not exceed 25°C/77°F and pH must be between 4 and 8
  • Distribute the spraying solution evenly over the soil/medium surface

Dosage

Capyphor is typically applied against soil pests at a rate ranging from 500 million to 5 billion nematodes per ha (200 million to 2 billion per acre).

Timing

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

Environmental conditions

  • Heterorhabditis bacteriophora is active between 16-35°C/61-95°F but performs best at temperatures between 19-33°C/66-91°F
  • Soil 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
  • 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
