Stage 4: Transition to Scale
Purpureocillium lilacinus is slowly enhancing nematode control in potato as we increase soil health through compost amendment. Biological control of soil-borne pests not fast requiring years to provide sufficient evidence for widespread adoption.

Funds Raised to Date
Most farmers use chemical control agents against potato cyst nematode in Guatemala.
Purpureocillium lilacinus as a biological control agent offers an alternative
Use of biological control to reduce damaging nematodes could translate to more sustainable production potatoes
Mission and Vision
Management of plant-parasitic nematodes in potato can dramatically improve potato yield and thus improve smallholder farmer livelihoods. Most growers need to recognize the damage inflicted by nematodes and undertake management options. One option is the used of biological control agents.
The addition of fungi such as biological control agents can help to reduce the population densities of damageing nematodes. We have applied Purpureocillium lilacinus as a biological control agent against potato cyst nematode.
Alternative to chemical controls
Planned Goals and Milestones
Expand to the use of biological control for potato cyst nematode control to new communities in Guatemala, Honduras, and Costa Rica.
|New Implemented Countries||Costa Rica, Honduras|
|Recruit||25 smallholder farmers|
|New Feature||Expand demonstration to new communities.|
