| Abstract/Contents: | "In small plot field trials conducted for three years the selectivity of some herbicides in selected grass species was studied. In the trials basic and double doses of herbicides were tested. Evaluations were made of potential phytotoxicity of herbicides in the grass species and their influence on number of fertile tillers, total seed yield, thousand seed weight, germination, germination energy and number of seed per fertile tiller. Based on trials Arrat (tritosulfuron 250 g kg-1 + dicamba 500 g ha-1) applied at 0.2 kg ha-1 and Aurora super SG (carfentrazone-ethyl 1.5 % + MCPP-P 60 %) at 1 kg ha-1 have been allowed for minor use in seed crops of perennial ryegrass, red fescue, cocksfoot, timothy, Kentucky bluegrass (KBG) and loloid as well as festucoid type of the festulolium. Arrat has been allowed for minor use also in meadow fescue. Husar (iodosulfuron 50 g kg-1 + mefenpyr-diethyl 150 g kg-1) applied at 200 g ha-1 shown good selectivity in KGB and cocksfoot but when it was applied in double dose the seed yield declined. In both types of the festulolium and timothy it is possible use the Callisto 480 SC (mesotrione 480 g ha-1). However, Callisto caused small chlorosis after application, mainly in loloid type of festulolium. Arkem (metsulfuron 200 g ha-1) at 30 g ha-1 applied in TM with CZ-600 (MCPP-P 600 g ha-1, 1.5 l ha-1) shown good selectivity in KBG, cocksfoot and timothy. Nevertheless, Arkem applied in double dose evoked the symptoms of phytotoxicity and decreased the seed yield of cocksfoot." |
