Abstract

Kupus (Brassica oleracea L. var. capitata Alef.) je jedna od glavnih povrtnih kultura. Po površinama i proizvodnji u svijetu je na četvrtom mjestu, iza rajčice, luka i lubenice. U svijetu se uzgaja na 210 000 ha s prosječnim prinosom od 22 t/ha, a u Republici Hrvatskoj se uzgaja na oko 8000 ha s prosječnim prinosom od 24 t/ha. Kupusni štitasti moljac (Aleyrodes proletella L.) je štetnik koji zadnjih šest do sedam godina postaje sve veći problem u proizvodnji kupusa i ako se na vrijeme ne suzbije može napraviti velike štete. U svrhu istraživanja insekticidnog učinka aktivne tvari spirotetramat na OPG-u Cafuk na lokalitetu Varaždin postavljen je poljski pokus. Pokus je postavljen po shemi slučajnog bloknog rasporeda u četiri ponavljanja sa šest varijanti uključujući kontrolu. Veličina osnovne parcelice iznosila je 21 m2. Očitavanje i uzimanje uzoraka obavljalo se na 20 biljaka u dva središnja reda sa svake osnovne parcelice. Očitavanja su obavljena prije tretiranja, 24 sata i sedam dana nakon svake aplikacije. Nakon provedenog pokusa rezultati su pokazali da aktivna tvar spirotetramat (Movento 100 SC) ima najbolju učinkovitost u suzbijanju ličinki kupusnog štitastog moljca kada se primjeni u početku zaraze, ali i u kombinaciji s aktivnom tvari deltametrin (Decis) koji doprinosi boljoj zaštiti.

Abstract (english)

Cabbage (Brassica oleracea L. Var. capitata Alef.) is one of the main vegetable cultures. By area and production it's on the fourth place in the world, behind tomatoes, onion and watermelon. It has been grown in the world at 210.000 ha with the average harvest of 22 t/ha. In the Republic of Croatia it has been grown at the area of about 8.000 ha with the average harvest of 24 t/ha. Cabbage Whitefly (Aleyrodes proletella L.) is a pest which presents a big problem in the last six to seven years and if it is not repressed it can cause a big damage. Aiming to research insecticide efficiency of the active substance spirotetramata field trial at OPG Cafuk near Varaždin was conducted. Trial was set up according to randomized block design with four replication swith six varieties, including the control. The size of the basic trial plot was 21 m². Scanning and taking the samples was done at 20 plants in two middle rows from each trial plot. The scanning was done before treatment, 24 hours and seven days after each application. After the trial, the results showed that the active substance spirotetramat (Movento 100 SC) is the most efficient in repressing the Cabbage Whitefly when applied at the beginning of contamination, but also in the combination with active substance deltametrin (Decis) which contributes to better protection.
