Mogućnost primene bifenazata i piridabena u suzbijanju šljivine rđaste grinje (Aculus fockeui) na višnji

Abstract

U poljskom ogledu izvedenom tokom 2020. godine na lokalitetu Mačvanski Metković (Opština Bogatić) ispitana je efi kasnost preparata na bazi bifenazata i piridabena u suzbijanju šljivine rđaste grinje (Aculus fockeui) na višnji. Preparat Acramite 480 SC (bifenazat) ispitan je u dve količine primene, 0,375 l/ha i 0,75 l/ha, dok je preparat Sanmite 20 WP (piridaben) primenjen u količini od 500 g/ ha. Ogled je izveden prema standardnoj, delimično prilagođenoj EPPO metodi za ispitivanje efi kasnosti akaricida u suzbijanju grinja paučinara u zasadima voćaka. Na osnovu rezultata ogleda može se zaključiti da je efi kasnost preparata na bazi bifenazata bila različita u zavisnosti od količine primene preparata. Efi kasnost ovog preparata primenjenog u količini od 0,75 l/ha bila je visoka i kretala se između 94,85% i 98,96%. Isti preparat u količini primene od 0,375 l/ha pokazao je slabu efi kasnost koja se kretala od 55,27% do 88,22%. Efi kasnost piridabena bila je visoka u svim ocenama (90,43% - 95,25%).

In the fi eld trial conducted in 2020 at the locality of Mačvanski Metković (municipality of Bogatić, Serbia), the effi cacy of products based on bifenazate and pyridaben in the control of the plum rust mite (Aculus fockeui) on sour cherry was examined. Product Acramite 480 SC (bifenazate) was tested in two application rates, 0.375 l/ha and 0.75 l/ha, while Sanmite 20 WP (pyridaben) was applied in an amount of 500 g/ha. The experiment was performed according to the standard, partially adapted EPPO method for testing the effi cacy of acaricides in the control of spider mites in fruit orchards. Based on trial results, it can be concluded that the effi cacy of bifenazate was different depending on the application rate of the product. The effi cacy of this compound applied in the amount of 0.75 l/ha of the product Acramite 480 SC was very high and ranged between 94.85% and 98.96%, respectively. The same product in the amount of 0.375 l/ha showed low effi cacy, which ranged from 55.27% to 88.22%, respectively. The effi cacy of pyridaben was high in all evaluations (90.43% - 95.25%).
