Abstract
- Cacopsylla pyri L. (Hemiptera: Psyllidae) je jedan od najvažnijih gospodarskih štetnika kruške. S obzirom na nove smjernice o održivoj uporabi pesticida i smanjenja rizika od negativnih učinaka pesticida stalno se iznalaze nova, ekološki prihvatljiva rješenja u zaštiti bilja. Cilj ovog istraživanja je bio utvrditi utjecaj biostimulatora na povećanje otpornosti kruške na intenzitet napada kruškine buhe. Istraživanje je obavljeno 2021. godine u pokusnom nasadu kruške, sorte Williams/BA 29, Poljoprivrednog instituta Osijek. U svrhu istraživanja obavljena su dva tretmana (T1 - Katon XT + Bombardier, T2 - kontrolni tretman - voda). Redovito praćenje brojnosti svih razvojnih stadija kruškine buhe provedeno je na prethodno obilježenim jednogodišnjim izbojcima pokusnog stabla u tri ponavljanja. Potvrđen je očekivani rezultat jednogodišnjeg istraživanja da je uporaba kombinacije biostimulatora dala statistički značajnu manju brojnost svih razvojnih stadija u odnosu na kontrolni tretman.<br />Cacopsylla pyri L. (Hemiptera: Psyllidae) is one of the most important economic pests of pear. With regard to new guidelines on the sustainable use of pesticides and reducing the risk of negative effects of pesticides, new, environmentally friendly solutions are constantly being found in plant protection. The aim of this research was to determine the impact of biostimulators in pear production on increasing resistance to the harmful pear psylla population. The research was set up in 2021 in an experimental pear plantation of the Williams/ BA 29 variety of the Agricultural Institute Osijek in two treatments (T1- Katon XT + Bombardier, T2- control treatment - water). Regular monitoring of the abundance of all developmental stages of the pear psylla was done on marked one-year-old shoots of the experimental tree in three repetitions. The expected result of the one-year study was confirmed, that the use of a combination of biostimulators gave a statistically significant lower number of all developmental stages compared to the control treatment.
