Definition and role in the reduction of phytosanitary products : monitor, using appropriate methods and tools, the presence and damage of bioaggressors but also the presence of auxiliaries. These methods include field observations as well as consultation of Plant Health Bulletins (BSV) regional Among the tools, there are traps: Barber pot, Berlèse apparatus, olfactory and chromatic traps, etc. This diagnosis, based on the vigilance of the producer and his adviser, leads to treatment only when necessary by referring to notions of infestation thresholds (stage of plant sensitivity, number of pests trapped in the plot or in its close environment, weather conditions favorable to parasitic attacks, etc.) in order to avoid costly and sometimes useless or counterproductive systematic phytosanitary treatments.
Against which pests? Potentially against all pests.
On which crops? All tropical crops are concerned even if they are not all mentioned in the regional BSVs.
When ? Before and during periods of crop sensitivity (Plant Health Bulletins) and also when necessary (at plot level).
In what conditions ? Monitoring is carried out at two scales: at the plot level, using field observations by the farmer and agricultural technicians (with or without trapping) and at the territory level with alerts and BSV.
Regulations : in the case of surveillance (or “monitoring”), the regulations relating to phytosanitary products do not apply to the traps and pheromones/attractants used. Beware, however, of the limit between surveillance and control (mass trapping).
Working time : increase for regular observation of plots, monitoring, cleaning and renewal of traps, research of information, etc.
Compatibility of alternative techniques with each other : compatible and recommended with all other techniques.
