Vanaga, I. (Latvia Univ. of Agriculture, Jelgava (Latvia))
Weed surveys showed that annual broad-leaved weeds were dominant in spring barley sowings in central Latvia. Field trials on broad-leaved weed control in spring barley showed that herbicides Granstar and Duplosan Super at 0,5 and 0,25 doses gave good weed control. There were statistically significant relationships between the abundance of broad-leaved weed and the yield of spring barley when barley yield and broad-leaved weed population were both high.
