Abstract

Leta 2020 smo v vinogradu pri Mirni Peči postavili poskus, v katerega so bile vključene tri nahrbtne naprave za škropljenje manjših vinogradov. Prva naprava je bila ročna škropilnica Solo 425, druga je bila baterijska škropilnica Solo Accu in tretji motorni pršilnik Solo 444. Ker se na tem območju v zadnjih letih močno pojavlja ameriški škržatek (Scaphoideus titanus), smo primerjali kakovost nanosa dveh kontaktnih insekticidov proti temu škodljivcu z omenjenimi napravami. Ugotovili smo, da je bil odstotek pokritosti pri vseh treh napravah za škropljenje podoben in je znašal več kot 35 %. Pri motornem nahrbtnem pršilniku je bilo ugotovljeno večje število odtisov kapljic na cm2. Na zunanjem delu vinske vrte, tako zgoraj kot tudi spodaj, je bil večji odstotek pokritosti z insekticidom kot zgoraj in spodaj v notranjem delu vinske trte. Tudi število odtisov kapljic na cm2 je bilo na zunanjem delu vinske trte večje kot v notranjosti. Po prvem škropljenju z insekticidom Exirel se število ličink ni bistveno zmanjšalo, medtem ko se je po drugem škropljenju z insekticidom Decis 2,5 EC zmanjšalo na minimum. Rezultati kažejo, da lahko tudi s kakovostnimi ročnimi in baterijskimi škropilnicami dosežemo primerljiv nanos in delovanje insekticidov za zatiranje ameriškega škržatka kot z motornimi nahrbtnimi pršilniki, ki jih trenutno največ uporabljamo za škropljenje manjših vinogradov.

Secondary title: Suitability of knapsack sprayers for the application of phytopharmaceutical products for the effective control of leafhopper Scaphoideus titanus Ball (Hemiptera, Cicadellidae) on grapevine (Vitis vinifera L.)
Secondary abstract: In 2020 the trial was performed in the vineyard near Mirna Peč, containing three backpack sprayers for spraying small vineyards. The first was hand knapsack sprayer Solo 425, the second was battery knapsack sprayer Solo Accu and the last motorized knapsack mistblower Solo 444. While in the last period on this area leafhopper (Scaphoideus titanus) is present, the quality of spray deposit after spraying with three backpack spraying devices and two contact insecticides to control this pest was compared. It was found out that the spray coverage of all three knapsack spraying devices was similar and amounted over 35 %. When using motorized mistblower the larger number of spray impacts per cm2 was determined. On the outer part of the grapevine, both on the top and at the bottom, the higher insecticide coverage was established compared to inner part of the grapevine, both at the top and at the bottom. Also the number of spray impacts per cm2 was larger on the outer part of the vine compared to inner part. After first insecticide spraying using Exirel the number of nymphal instars did not decrease greatly, while after second insecticide spraying with Decis 2,5 EC their number decreased to a minimum. Results show that comparable spray deposit and insecticide effect on leafhopper can be achieved also with hand knapsack sprayers and battery knapsack sprayers compared to motorized mistblowers, which are most in use for spraying small vineyards.
