Efikasnost nekih hebicida u suzbijanju korova u pšenici

Abstract

Field trials were carried out in 2001, 2002 and 2003 to evaluate the efficacy of several herbicides applied individually or in combination in winter wheat in the region of Southern Banat. The examined herbicides were: 2,4-D, Fluroxypyr, Tribrnuron - methyl, 2,4 - D + Florasulam, Bentazon + Dicamba, Triasulfuron + Dicamba, Iodosulphuron - methyl - sodium + Amidosulphuron. The herbicides were applied after wheat tillering. Chenopodium album, Chenopodium hybridum, Cirsium arvense, Convolvulus arvensis, Consolida orientalis, Delphinium consolida, Fumaria officinalis, Galium aparine, Lathyrus tuberosus, Polygonum convolvulus, Sinapis arvensis, Stellaria media, Veronica hederifolia and Viola tricolor were found to be the most frequent weeds on location. Sinapis arvensis and Chenopodium album were the most susceptible weeds to all herbicides tested in this investigation. The other species were somewhat less susceptible, but herbicide efficacy was good or satisfactory for all. The most tolerant were Galium aparine and Convolvulus arvensis. The data suggest that all applied herbicides could be successfully used for controlling broad-leaved weeds in winter wheat crops in the region of Southern Banat.
