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.
