Residual effect on natural enemies (persistence)

Many agents remain harmful for a certain period after application. In natural enemies, this persistence is expressed in the number of weeks during which the agent remains harmful for the natural enemies. Only after the indicated period can the parasite or predator concerned be introduced or reintroduced successfully.

Side effects on bumblebees

All results for side effects on bumblebees were obtained using Bombus terrestris. Side effects in other bumblebee species may vary. For bumblebees, four categories have been defined for the purposes of indicating the working method to be followed when using the pesticides concerned. Before covering and removing, make use of the Beehome function of the bumblebee hive.

Residual effect on bumblebees (persistence)

The residual effect of an agent on bumblebees is indicated in the number of days during which the bumblebees cannot be kept in the greenhouse. Only once the indicated period has passed will the residue have broken down sufficiently, and will bumblebees suffer no adverse effects from it. If no data are presented, the persistence is unknown.
