Abstract
Lentil production in the black soil zone is limited by the susceptibility of the crop to diseases such as sclerotinia stem rot. The objective of this project was to determine stem rot control strategies in small-seeded lentil by examining the impact of plant density, cultivar, fungicide treatment and timing of application on stem rot severity and yield. The relationship between flower petal infection and stem rot severity was also examined. Randomized complete block field experiments of three replicates were established at Rosthern and Melfort, SK and assessed for flower petal infection, disease severity and yield in 2000. Results of this single year of data indicated that fungicides reduced stem rot severity at both locations but increased yield only at Melfort, where later timing of application resulted in greater yield than early. Stem rot severity varied with cultivar however the cultivar with the greatest severity also had the greatest yield. Plant density had no effect on stem rot severity, but the lower plant density resulted in lower yield than the higher plant density. Flower petal infection was positively correlated with final disease rating only at Rosthern.
