Exhibiline Hb - Parasitic Nematodes

Heterorhabditis bacteriophora

Exhibitline Hb biological control agent contains the insect pathogenic nematode, Heterorhabditis bacteriophora, as infective juveniles. It is used to control black vine weevil larvae in ornamentals and berries. It is also used for curative chafer grub control in turf.

Target Pests

• Black vine weevil
• Strawberry root weevil
• Chafer grub

Key Features

• Provides at least 4 weeks of protection from black vine weevil and strawberry root weevil
• Provides effective curative control of Chafer grub in turf
• Heterorhabditis bacteriophora  will actively seek out vine weevil and chafer grub larvae in the coil.
• Simple and safe to use, bacteriophora occurs naturally in soils.
• Apply through ground sprayers or irrigation
• Apply anytime whenever ground temperatures are above 12°C

How It Works

• Harmless to the ornamental crops, humans, the environment and other beneficial insects, these nematodes actively seek out vine weevil larvae by swimming in the thin film of water on soil particles. They locate hosts by detecting carbon dioxide and other waste products. After locating pest larvae, nematodes invade through natural body openings and inject bacteria into the insect. Bacteria develop within the insect and it dies of septicemia.
• Under optimum conditions, the insect can die within 12-24 hours. Insect mortality will depend on the environmental temperature. The minimum soil temperature should be 12°C for nematodes to work most efficiently and the maximum soil temperature should be no more than 26°C.

Delivery System

• 250 million entomopathogenic Heterorhabditis bacteriophora nematodes in an inert carrier in sealed trays
