Implication

Laboratory and field experiments evaluate seed treatments' impact on carrot disease control and yield.

Key Points

Evaluate the effectiveness of various seed treatments on controlling Alternaria dauci and improving carrot yield.
Conducted laboratory, pot, and field experiments at Haramaya University.
Treated naturally-infected seeds with fungicides, hot water, bleach, and salt.
Used a completely randomized design with appropriate replications for experiments.
Carbendazim treatment reduced infection to 1.5%, vs. 77% in untreated seeds.
Mancozeb-treated plots showed 28.8% mean severity at 95 days after sowing.
Root yield increased significantly, with carbendazim yielding 12.23 tons/hectare compared to control.
