Because of the different environmental conditions presented over time, it is required to test the efficacy of a specific active substance over several years to develop a true idea of the value of the management. Therefore, the on-farm study started in 2012 is being continued in 2013 at four different locations.
Similar to last year’s methodology, swarming of the cherry fruit fly (Rhagoletis cerasi) will be observed through use of yellow sticky card traps supplied with a pheromone lure placed within the cherry orchards. At the beginning of swarming (detected by observation of the sticky traps) we start spraying Beauveria bassiana at the recommended weekly intervals. The substance is tested in two different concentrations. Vektafid-A is our control treatment insecticide. According to foreign studies, efficiency of the substance is influenced by both air humidity and solar radiation. For 2013 meteorological stations were set out in the test orchards. Evaluation of the study on each farm and plot will be made by investigation of the crop’s infection rate (percentage of infested cherry fruits).
