Abstract
Crop loss studies were conducted in wheat and lentil near Delisle, Laird, and Vonda, Saskatchewan in 1991 and 1992. Wheat yield and biomass were reduced at one of four sites . Lentil yield was reduced at three of six sites; while lentil biomass was reduced at four of six sites. Wild tomato was most competitive when it
emerged early and at high density, and when the crop vigour was low. In the fall of 1992, data were collected on the effect of wild tomato on harvestability. Wheat harvestability is not affected by wild tomato. Wild tomato caused soil to adhere to the lentil seed (earth-tag), and increased the moisture content of the lentil sample. Wild tomato berry juice mixed with harvest debris and this mixture plugged the concaves and the augers of the combine. Wild tomato seed is being spread by harvest equipment.
