Project code: 2814707211
Contract period: 15.02.2013 - 14.02.2016
Budget: 167,428 Euro
Purpose of research: Applied research

"The reliability of the method was confirmed by preliminary tests. These tests included methods for propagating plants, selection of pest species, rearing of pests susceptible to plant protection substances, the verification of known and development of new test methods. For this the analyses of residues done by a partner were essential (sub-project 2). For the bioassays pest species of thrips, white flies, aphids and spider mites were collected by partners in greenhouses where pest control had failed. The bioassays using 27 plant protection substances revealed that for pests from many origins at least one MoA was ineffective, but for pests from most origins there was at least one product that was effective. Furthermore, why some bioassays indicated a plant protection substance was effective but in practice proved ineffective was analyzed and the stability of the resistance after application was determined. The implementation of our findings in plant protection was done by presenting the results, carrying out joint experiments and developing methods for detecting reduced effectiveness.
During this project issues arose, which need to be resolved by the partners, for which further funding is required. By combining bioassays with biochemical and molecular detection, and analyses of residues of plant protection substances would reduce the time taken and cost of examining single individuals in order to determine the distribution of resistance within a population. In addition, this would result in a reduction in the scale of the rearing activities needed."
