Efficacy trials are performed according to EPPO standards on efficacy evaluation of PPPs (PP1 series) in their last version.
The efficacy evaluation of a PPP represents a pre-requisite for its authorization. Efficacy trials  provide information for the assessment of the product performance against pest as well as on the nature and the extent of any adverse effect on the crop, on the yield of the treated crop and on the succeeding crops:  direct efficacy and crop safety.
The nature and the extent of the benefits resulting from the use of a PPP, are compared with the existing reference products and with damage thresholds, and they allow to set its conditions of use.
These trials allow the assessment of the level, the duration and the uniformity of the control/contrast/protection or other effects undertaken by the product.
The personnel runs tests tailored for client’s needs.
