Abstract
The study has been made at Research Station for Fruit Growing Voinesti between 2020-2021, regarding apple susceptible to disease ('Jonathan' and 'Golden delicious'), 3 biological products being tested in the combat of the apple codling moth (Cydia pomonella L.), including the use of pheromone traps in order to track the pest. We mention that the codling moth is one of the most harmful species with a high incidence against the quality of fruits and their commercial value, regarding all the apple tree cultures of the Voinesti tree growing zone. As a means of tracking and warning, ATRAPOM pheromone has been used, as well as some biological products treatments: Bactospeine DF conc. 0.1 %, Laser 240 SC conc. 0.06%, MadexTop conc. 0.001%. Some high biological efficiency products have been noticed: Laser 240 SC conc.0.06% with a high 4.0% frequency attack, Bactospeine DF conc. 0.1% with 6%, while the MadexTop conc. 0.001% product had only registered a 2% damage, comparing to the chemical product Karate zeon conc. 0.015% that had an attack frequency of only 11%, while the untreated control group has been registered a 19% attack. Focusing towards using biological products in the combat of some apple tree pests, it will be gradually imposed, constituting the main factor in order to get some productions containing a small amount of phytosanitary products.
