In an environment friendly cultivation project biological crop protection is preferred to obsolete pesticides.
Nowadays organic combatants, such as ichneumon wasps, gallflies or ladybirds are used most of the time.
When using organic combatants, it is obviously important that the applied combatants remain within the cultivation space. For this purpose the air windows are fitted with insect gauze in harmonica form, which also keeps out undesired insects from the greenhouse.
In addition, organic pesticides are used on a non-chemical synthetic basis. It are natural agents that hardly cause any damage to the environment.
Chemical pesticides are still only allowed to a limited degree and can therefore still be applied, although moderately.
However, modern consumers greatly prefer products without chemical agents. Moreover, the requirements with regard to the environment and food safety are becoming increasingly stricter, so that it is advised to solely work with organic agents.
