Organic crop protection
Disease and pest control in the crop is done using organic crop protection.
Organic crop protection is the control of insect pests by introducing a natural enemy of the insect pest.
Insect pests such as whiteflies can damage the crop in our greenhouses. By introducing ichneumon wasps in the greenhouse, whiteflies are controlled naturally. This is because the ichneumon wasp eats the larvae of the whitefly and also lays its eggs in the pupa of the whitefly. So the pupa of the whitefly does not yield a whitefly, but a new ichneumon wasp. We introduce the ichneumon wasp by hanging cards containing eggs of the ichneumon wasp in the greenhouse.
Aphids may also be a problem in the greenhouses. The can do severe damage to various crops, because the aphids feed on plant saps and release a sticky substance (honeydew). This makes the leaves of the plant sticky and can cause fungus. For organic control of aphids we use a different species of ichneumon wasp, called the Aphidius matricariae. Particularly the larvae of this ichneumon wasp feed on aphids. This creates a biological balance.
And there are plenty more natural enemies we can use for natural control of diseases and pests. The species of insect we use differs from crop to crop. The use of organic crop protection is better for the environment and for people. And of course for a pure crop!
