Abstract
(not available in English)
The project proposal envisages a four-year study (2 years' apple orchard and 2 years' vineyard) to investigate the influence of technical and technological factors of pesticide application on the main characteristics of the study: Residues of active pesticide substances in the fruit, occurrence and spread of pests, fruit quality, and deposition and drift of the spray. The technical and technological factors of the application are the spraying rate, the spray concentration and the nozzle type with its sub-factors. The spraying rate is determined according to the TRV method (tree row volume) and a 50% reduction, while the concentration is determined according to the recommended (FIS registration) and its 20 and 40% reduction. According to the technological map for the protection of permanent plantations, two types of nozzles are used for spraying: Standard TR and Air-Injector ITR. The residues of the active substances are determined using the liquid chromatography with mass spectrometer (LC-MS/MS) method in an accredited laboratory, while the quality of the fruit and the occurrence and development of the pests are determined in the Faculty of agrobiotechnical sciences central laboratory. The deposit and spray drift are determined using the spectrophotometric method defined by the ISO 22866:2005 standard. The field trial should provide information on whether it is possible to reduce the application rate and concentration of sprays (low-volume pesticide management) and at the same time improve the quality of the fruit with the same or better biological effect on the pests. In addition, the improved quality of spraying will reduce drift, which will have an impact on better pest control and the possibility of reducing the number of applications.
