Sanimir Enchev tand Rumen Bazitov

Abstract: During 2014 and 2015, a field experiment was carried out on the experimental fields of Agricultural Institute – Shumen with the new grain sorghum variety Maxibel. The biological influence of the herbicides Gezaprim 90 WG, Dual Gold 960 EK and Stomp 330 EK was studied. Dual Gold and Stomp showed low efficiency in relation to Amaranthus retroflexus, as well as Gezaprim towards Solanum nigrum. High efficiency towards Solanum nigrum was shown by Dual Gold, and the same herbicide together with Stomp gave excellent control of Datura stramonium.
During both years of testing, most unsatisfactory performance was manifested by Stomp towards Amaranthus retroflexus. The effect of the studied herbicides on the development and yield of the grain sorghum variety Maxibel was positive. The studied herbicides do not exhibit phytotoxicity to the grain sorghum.
