This study, conducted in the framework of the DEPHY EXPE Ecophyto dispositive, over a six-year period, aims at using agronomic and technical levers in order to reduce by 50 % the use of conventional phytopharmaceutical products in two cropping systems (arable and vegetable crops). After five years of experimentation, the majority of the expected technics were used and the application of some levers was analyzed. Some problems without solutions were identified, such as the control of bio-aggressors in canned peas, weeding in onion and modulation of thresholds regarding populations of auxiliaries. Results showed in average a lower performance of IFT50 conditions (reduced by 50% for treatments at the cropping system scale) that varies depending on the considered crop and year. However, the performances obtained are encouraging and can be further improved in order to optimize the benefits of certain levers.
