Abstract
Multiple-Location on-farm demonstrations were conducted over 1993-2002 ýto evaluate the effect of crop rotation on productivity of barley and control of ýmealy bug (Ground pearl) in the dry regions of Syria. The results indicated that ýbarley yield was increased by 21-24% after fallow compared with yield after ýbarley, and control of mealy bug dropped from an infestation level of 7-10 ýinsect/plant to 1-2 insect/plant. These results indicated effectiveness of crop ýrotation as an option to control this serious insect which causes significant yield ýloss.ý
