Title : CONTROL OF A PROBLEMATIC WEED Sorghum halepense FROM MAIZE CROPS IN ROMANIA
Abstract : Romania has one of the highest degrees of infestation with Sorghum halepense because this weed is a thermophilic and heliophilous species. It found satisfactory growth and development conditions due to the high fertility of soils, especially under the conditions of substantial underground water intake. Maize is one of the very sensitive crop plants to infestation with Sorgum halepense especially in the early stages of development. The only effective way to control this weed is to use selective herbicides for maize crops having aggressive action on this weed. The aim of this study was the control of Sorghum halepense from seeds and rhizomes by post-emergence application of nicosulphuron-based herbicides in various doses and different development stages of weeds in maize crop. The experiments were carried out in Afumati farm, Ilfov County, in two years 2015 and 2016, and they were placed in randomized blocks and the observations targeted the degree of effectiveness in controlling weeds and crop selectivity. The herbicides based on nicosulphuron had a good efficacy in controlling Sorghum halepense in maize crops. At the dose of 1.0 Lha-1 this weed was not fully controlled, in conditions of strong infestation. The best results were obtained at the dose of 1.5 Lha-1 applied in sequential treatments. Also, no phytotoxic symptoms were shown in experimental fields
