Negative effects

Work organization

- Fewer passages of phytosanitary treatments.

- Absence of entry period and pre-harvest period allowing not to interrupt the maintenance of the culture and its marketing.


- Short storage time (generally 48 hours maximum for live insects and mites).

- Need to keep auxiliaries cool.

- Limited choice of phytosanitary products compatible with biological control.




- Less negative impact on soil fauna, therefore improving fertility and the soil in general. 

Product qualities

- Fewer residues of phytosanitary products.


- Lower impact on biodiversity.

- Reduction in the transfer of pollutants to water and air thanks to the reduction in insecticides.

Energy consumption

- A priori less if reduction of chemical treatments.


- If necessary to increase the temperature of the greenhouse (in the Hauts de la Réunion) for the good development of auxiliaries (eg the bug Macrolophus) .
