Factors studied

Positive effects

Negative effects

- For certain alternative products, the absence or the very short duration of entry and pre-harvest periods mean that maintenance of the crop and its marketing are not interrupted.

- More or less long-term effect of certain microorganisms depending on climatic conditions (eg entomopathogenic fungi).

- Ensure that the products are available on the French overseas departments market (shipping and storage at distributors is sometimes difficult for bacteria-based products).

- Preservation of products based on living organisms under very specific conditions.

- Quick use of the products after opening the bag.

- Reasoning for applications in order to prevent resistance phenomena.

- Limited choice of conventional phytosanitary products compatible with these alternative products.

- Best possible valuation at the sale of the products.

- Increase in the cost of labor for treatments.

- Necessary expenses for the purchase of the products.

- Variable treatment efficiency.

- Ecosystem balances respected.

- Sustainable phytosanitary management.

- Fewer toxic residues.

- Better visual aspect if reduced damage. 

- Less risk to the environment.

- If non-specific alternative products, possibility of negative impact on useful biodiversity.

- Increase because in general it takes many successive applications.
