The research was realized during the growing season in 2013 in an apple orchard of the cultivar Golden Delicious near the village Nosislav (district Břeclav, elevation 170m). The efficiency of four products against San José Scale (Quadraspidiotus perniciosus) was investigated. The first adult San José Scale males were found in pheromone traps on the 28th of May. Occurrences of the first and second generation of the first instar nymphs (crawlers) were calculated according to effective temperatures sum to be on the 20th of June and 6th of August. The highest efficiency against San José Scale (59.6 to 60.9%) was found in a product based on Beauveria bassiana. The efficiency of a product based on the oil of Pongamia pinnata was between 41.8 and 56.9%. The efficiency of a product based on orange oil was lower, between 32.8 and 39.6%. The lowest efficiency, only 17%, was detected in a product with the active substance spinosad.
