Abstract:V letu 2017 je bil izveden poljski poskus v posevku oljne ogrščice, v katerem smo ocenjevali stopnjo učinkovitosti insekticidov za zatiranje repičarja (Meligethes aeneus F.) in ogrščičnega kljunotaja (Ceutorrhynchus napi G.). Testirani so bili štirje insekticidi: Biscaya® (tiakloprid), Decis 2,5 EC® (deltametrin), Mavrik 240 EW®(tau-fluvalinat) in Karate Zeon 5 CS® (lambda-cihalotrin). Ocenjevanje učinkovitosti 100 in 200 % odmerkov je potekalo 2., 4., 6., 8. in 10. dan po nanosu sredstev. Odmerek insekticida (100 proti 200 %) v večini ocenjevalnih obdobij ni imel vpliva na stopnjo učinkovitosti insekticida. Pri vseh testiranih insekticidih je učinkovitost po šestih dneh padla pod 45 %, kljub temu pa ne moremo trditi, da je testirana populacija repičarja in kljunotaja razvila odpornost na testirane insekticide.

Title:Assesment of insecticide efficacy in controlling canola beetles (meligethes aeneus) and rape stream (ceutorrhychus napi)
Abstract:In 2017, a field experiment was carried out in a rape seed crop, in which we evaluated the degree of insecticide efficacy for controlling the canola pollen beetle (Meligethes aeneus F.) and the rape stem weevil (Ceutorrhynchus napi G.). The fallowing four insecticides were tested: Biscaya® (thiacloprid), Decis 2,5 EC® (deltametrin), Mavrik 240 EW® (tau-fluvalinate) in Karate Zeon 5 CS® (lambda-cihalotrin). Evaluation of the efficacy of 100 and 200% of doses took place on the 2nd, 4th, 6th, 8th and 10th day after the application of the insecticides. The dose of insecticide (100% vs. 200%) in most assessment periods did not have an effect on the degree of insecticide efficacy. For all tested insecticides, the efficacy after six days has fallen below 45%, however, we can not claim that the population pollen beetle and rape weevil has developed resistance to tested insecticides.
