Chemical control of weeds in soyabeans


, : Chemical control of weeds in soyabeans. Zashchita Rastenii (2): 32

Treflan at 4 l/ha applied before sowing soyabeans was not effective against weeds; at 6 l/ha it decreased populations of monocot weeds by 65-80% and germination by 19%. Linuron at 3 kg/ha gave effective control of dicot weeds and increased the seed yields.
