Harmful insect pests reduce crop yield and quality, and the use of traditional pesticides to control these pest is expensive and can be dangerous to the growers and the consumers if proper handling is not followed. Additionally, watering crops under pest-exclusion nets can sometimes require raising the net, allowing pest insects to gain access to the crop.



Netting (as row covers or framed net-houses) excludes many insect pests. Allowing nursery seedlings to grow virus free (no insects to introduce or transmit the pathogens) and crops to mature without (or with delayed) predation by insect pests. Predatory/beneficial insects can be introduced into, and be confined by, the netting structures to prey on harmful pests. In addition, the driplines irrigation provide consistent water without disturbing the netting.

Target Beneficiaries

Smallholder Farmers

Mission and Vision

Provide growers with simple, cost-effective and environmental benign methods to grow high-quality vegetable crops for local consumption and export.

Innovation Description

In addition to the pest-exclusion netting, the use of supplemental (drip-line) irrigation inside the Net-houses can have real advantages for improved crop production/yields. This is especially true for crops produced during the dry-season. Additionally, the use of beneficial/predatory insects to control pest insects within the net-houses has proved successful.

Planned Goals and Milestones

Establish business (net-house kits and trainers) and financial (loans) models to allow farmers access to this technology on a broader scale in Kenya and neighboring countries.
