Abstract

Duhanov resičar (Thrips tabaci Lind.) najvažniji je štetnik duhana. Izraziti je polifag i jedan je od najvažnijih štetnika u proizvodnji luka (Allium cepa L.) na otvorenom. Cilj je rada utvrditi učinkovitost insekticida Movento SC 100 na osnovi aktivne tvari spirotetramat u programu suzbijanja duhanova resičara na luku te usporediti njegovu učinkovitost s registriranim pripravcima za tu namjenu. Na lokalitetu Lipovac, na proizvodnom polju PIK Vinkovci, postavljen je poljski pokus prema EPPO protokolu PP 1/85. Kako bi se utvrdio optimalan rok tretiranja, na svakoj osnovnoj parceli obavljan je i vizualni pregled biljaka. Obradom prikupljenih podataka utvrđena je visoka učinkovitost pripravka Movento 100 SC, u suzbijanju duhanova resičara (Thrips tabaci) na luku. Učinkovitost registriranih pripravaka u odnosu na Movento SC 100 tijekom prvog i drugog tretiranja je podjednaka, dok se jasne razlike u učinkovitosti Moventa SC 100 i registriranih pripravaka vide nakon trećeg i četvrtog tretiranja. Movento SC 100 značajno je učinkovitiji i nakon 17 dana od primjene.

Abstract (english)

Tabacco thrips (Thrips tabaci Lind.) is the most important tobacco pest. It is a polyphag and one of the most important pests in the open air (Allium cepa L.). The aim of the work is to determine the effectiveness of Movento SC 100 insecticide based on the active substance spirotetramate in the program to control the tobacco thrips and to compare its efficacy with the registered formulations for this purpose. At the Lipovac site, on the production field of PIK Vinkovci, a fild trial was conducted according to EPPO protocol PP 1/85. In order to establish an optimal treatment period, a visual inspection of plants was performed on each basic plot. Statistical analysis of the data collected showed the high efficiency of the Movento 100 SC formulation, in the control of the Thrips tabaci on the onion. The efficacy of the registered formulations compared to Movento SC 100 during the first and second treatments is alike, while clear differences in the efficacy of Movent SC 100 and the registered preparations are seen after the third and fourth treatments. Movento SC 100 is significantly more effective after 17 days of application.
