- Alternate Title:
REDUCTION OF POPULATION OF THE HOP SNOUT WEEVIL (Neoplintus tigratus porcatus [Panzer]) ON HOP (Humulus lupulus L.).
- نبذة مختصرة :
The hop snout weevil (Neoplintus tigratus porcatus [Panzer]) is a monophagous pest that feeds on hop plants (Humulus lupulus L.). Larvae cause damage with boreholes inside the underground parts of plants, resulting in impaired water and nutrients uptake and consequently financial loss. Hop plants grow slowly, reach lower yields and hop quality. In 2019 and 2020, we studied the effectiveness of the three products on the control of the population of hop snout weevils. In 2019, the Nemakil 330 statistically significantly reduced the number of holes in the underground parts of hop stems, which resulted in a smaller number of larvae. In 2020, we additionally included the Maska and Maska Universal. The best result of reducing the population of hop weevils (number of larvae and holes) was achieved with a combination of the Maska and Maska Universal. [ABSTRACT FROM AUTHOR]
- نبذة مختصرة :
Hmeljev rilčkar (Neoplintus tigratus porcatus [Panzer]) je monofagni škodljivec, ki se prehranjuje izključno na rastlinah hmelja (Humulus lupulus L.). Ličinke vrtajo v podzemne dele rastlin ter ovirajo sprejem vode in hranil, s čimer povzročajo gospodarsko škodo. Rastline hmelja slabše rastejo, dosegajo nižje pridelke in slabšo kakovost pridelka. V letih 2019 in 2020 smo proučevali učinkovitost treh pripravkov na zmanjševanje populacije hmeljevega rilčkarja. Pripravek Nemakil 330 je v letu 2019 statistično značilno zmanjšal število izvrtin na podzemnih delih stebla hmelja, posledično je bilo tudi manjše število ličink. V letu 2020 smo vključili še pripravka Maska in Maska Universal. Najboljši rezultat zmanjšanja populacije hmeljevega rilčkarja (število ličink in izvrtin) smo dosegli s kombinacijo pripravka Maska in Maska Universal. [ABSTRACT FROM AUTHOR]
