Parasitoids

Parasitoid Biocontrol

The immature biocontrol agent grows and develops in or on the pest, killing it in the process. Both insects and nematodes fall into this category. Learn more about how parasitoid biocontrol works.

Biopesticides

Biopesticide Biocontrol 

Microorganisms or microbes (fungi, bacteria and viruses) and plant extracts can reduce pest populations by killing, repelling, excluding them, or by hampering their growth or reproduction. They can also boost the defenses of a plant, making it more resilient against pest attack. Learn more about how biopesticide biocontrol works

Insect-killing nematodes

Insect-killing nematode Biocontrol

Nematodes are tiny worms. Some of them reproduce inside insects, killing in the process. They are called entomopathogenic nematodes, or EPNs. Learn more about how insect-killing nematode biocontrol works.

Weed-Feeders

Weed-Feeder Biocontrol

Biocontrol agents that control weed pests can either be insects (which feed on weeds) or microbes (which infect/cause disease on weeds). Learn more about how weed-feeder biocontrol works.
