Abstract

V letu 2021 smo izvedli poljska poskusa, v katerih smo preučevali učinkovitost ekološkega in integriranega škropilnega programa na zatiranje stenice marmorirane smrdljivke (Halyomorpha halys Stål) v dveh ločenih nasadih jablan na Primorskem. Ocenjevali smo velikost populacije odrasle stenice, njenih ličink in delež plodov s poškodbami v 9- do 12-dnevnih presledkih. Škropilni program v ekološkem nasadu, temelječ na rastlinskih izvlečkih, naravnih piretrinih, spinosadu, kaolinu, naravnih milih in azadirahtinu, je bil v povprečju med 45- in 66-odstotno učinkovit za zatiranje stenic in je za 65 do 78 odstotkov zmanjšal delež plodov s poškodbami ob obiranju. Pri dveh integriranih škropilnih programih, temelječih na uporabi snovi acetamiprid, deltametrin, fosmet, spinosad in rastlinskih izvlečkov, smo dosegli od 69- do 93-odstotno učinkovitost pri zatiranju odraslih stenic. Uporaba pripravkov v integriranem programu je za 70 do 80 odstotkov zmanjšala delež plodov, poškodovanih od stenic, ob obiranju. Iz podatkov, ki smo jih dobili v poskusu, lahko sklepamo, da so lahko škropilni programi, ki temeljijo na podlagi testiranih razpoložljivih aktivnih snovi, do 80-odstotno učinkoviti. To kaže, da zgolj z uporabo testiranih pripravkov ni možno zagotoviti dovolj temeljitega zatiranja stenice. Hkrati je z uporabo insekticidov treba izvajati še druge biotične in biotehniške metode zatiranja

Secondary title: Chemical control options against brown marmorated sting bugs (Halyomorpha halys Stål) in apple orchards with organic and integrated production
Secondary abstract: In 2021, we conducted field experiments to study the effectiveness of organic and integrated spraying programs to control brown marmorated stink bug (Halyomorpha halys Stål) in two separate apple orchards in the Primorska region. We evaluated the size of the population of adult bugs, larvae, and the proportion of fruit damaged by bugs in 9 to 12-day intervals. The spray program in the organic orchard based on plant extracts, natural pyrethrins, spinosad, kaolin, natural soaps, and azadirachtin was, on average, 45 to 66 % effective in controlling marmorated bugs and reduced the proportion of damaged fruits at harvest by 65 to 78 %. In two integrated spraying programs based on the insecticides acetamiprid, deltamethrin, phosmet, spinosad, and plant extracts, a 69 to 93 % effectiveness in controlling adult bugs was achieved. Using preparations in an integrated program reduced the proportion of damaged fruits by bugs at harvest by 70 to 80 %. From the data obtained in the experiment, we can conclude, that spraying programs based on tested available active substances can be up to 80 percent effective. This shows that it is impossible to ensure sufficient thorough control of marmorated bugs just by using the tested preparations. Simultaneously, beside the insecticides, other biotic and biotechnical management methods must therefore be implemented
