The importance of companion plants in greenhouse vegetable production
Currently, in greenhouse vegetable production, the use of companion plants has established itself as an effective and sustainable solution for crop protection. Among the most commonly used species is Lobularia maritima, recognized for its high ability to attract beneficial insects.
Companion plants are introduced into the greenhouse environment with the aim of promoting biological balance, reducing the need for chemical plant protection treatments. They serve as a habitat for beneficial organisms—such as predators and parasitoids—that help control common pests in vegetable crops.
In the case of Lobularia maritima, its small flowers, rich in nectar and pollen, are especially attractive to beneficial insects, such as syrphids (whose larvae feed on aphids), parasitoids, and other pollinators. By providing food and shelter, this plant contributes to the establishment and retention of these beneficial insects within the greenhouse, increasing the effectiveness of biological control.
The use of auxiliary plants allows:
- Reduce pesticide use, promoting more sustainable production
- Improving functional biodiversity within the greenhouse
- Creating more balanced and resilient production systems
Another key aspect is their preventive role: by maintaining active populations of beneficial insects, it becomes possible to control potential infestation outbreaks early on, preventing them from developing.
At Plantalgarve, we offer trays of companion plants, such as Lobularia maritima, ready to be integrated into your greenhouse and to support vegetable production. This practical solution allows growers to implement biological control strategies in a simple, effective manner, tailored to the demands of modern agriculture.
