Heterorhabditis bacteriophora

Heterorhabditis bacteriophora is a species of beneficial nematode commonly used in biological pest control. These microscopic roundworms are parasitic and are known for their effectiveness in controlling a variety of insect pests. Heterorhabditis bacteriophora nematodes infect their hosts by entering through natural openings or the cuticle. Once inside the host, they release symbiotic bacteria, typically of the genus Photorhabdus, which quickly multiply and cause septicemia, ultimately killing the host within a few days. This species is particularly effective against insect pests such as larvae of beetles (including grubs). Heterorhabditis bacteriophora nematodes are usually applied to the soil. This biological control method, offers a natural and environmentally friendly approach to pest management in agriculture and horticulture.

• 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/media surface

Application through irrigation systems:

• Pressure-compensated irrigation systems are recommended. If not available, spray or drench applications are recommended. For injection through Dosatron/Venturi systems, please contact your local representative for specific advice
• Spray the solution as soon as it is prepared and within a short timeframe. Do not store mixed suspensions
