Abstract
In our investigation we used different weed control technologies in the different phenology states of the maize. The experiment have beencarried out in Hódmezővásárhely, in the Experiment garden of the Pilot farm of University of Szeged Faculty of Agriculture, on meadowchernozem soil, on 24 m2 plots, in 3 replications, randomized blotch design. The experiment can be regarded as 15 weed-control strategieswhere, in addition to the untreated control, six chemicals or chemical-combinations are applied (Spectrum 720 EC, Motivell Turbo D,Stellar + Dash HC, Clio + Akris SE + Dash HC, Clio + Dash HC) in five different times (pre, early post, post and two late post) and eightmechanical weed-control technologies were used. Hoeing took place connected to the herbicide treatments in different times: until 2-3-leaveage weedless, in 3-4-leave age hoed once, from 3-4-leave age weedless, in 6-7-leave age hoed once, from 6-7-leave age weedless, in 8-leaveage hoed once, from 8-leave age weedless.Our results were assessed by chemical efficiency examination, maize length measurement, corncob-length and fertility examination,Sorghum plant-number determination and yield weighing carried out in four periods. The data were evaluated by a one-factor analysis ofvariance and a two-factor linear regression analysis.

Summary
Clio + Dash HC) juttattunk ki öt időpontban (pre, korai poszt, poszt és két késői poszt) és nyolc mechanikai gyomirtási technológiát alkalmaztunk. Gazdagné Torma (1990) tapasztalata, hogy a nehezen írtható, illetve veszélyes gyomnövények előretörésével a kukorica posztemergens gyomirtása nélkülözhetetlen. Kezelés) végzett gyomirtó szer hatékonyság és fitotoxicitás vizsgálattal, kukorica magasságméréssel, csőhosszúság és termékenyültség vizsgálattal, fenyércirok tőszám és bokrosodás meghatározással, valamint termésméréssel értékeltük. Spektrum kezeléseket a kukorica [4,5,6] leveles korában Motivell Turbo D-vel (2.), illetve Stellar és Dash (3.)
