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.

Problem

Most farmers use chemical control agents against potato cyst nematode in Guatemala.

}

Solution

Purpureocillium lilacinus as a biological control agent offers an alternative

Target Beneficiaries

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.

Innovation Description

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.

Competitive Advantage

Alternative to chemical controls
