Author(s): Geray Hagos*, Kiros Meles and Hadush Tsehaye
Diseases like late blight are among the major constraints that limit tomato production in most tomato growing
regions. Field experiment was conducted in North Western Tigray in 2018 main season with objectives: to investigate
the effect of varieties and fungicide application frequencies on late blight disease development and tomato fruit
yield. The treatments consisted of four tomato varieties (Melkashola, Melkasalsa, Sirinka-1 and Gelilema) and five
application frequencies of the fungicide Matco 72% WP including the control. The experiment was laid out in a split
plot design with three replications. Results indicated that integration of varieties and fungicide spray frequencies
significantly reduced late blight disease development and maximizes tomato fruit yield. Melkasalsa variety is found
better with lowest disease incidence (36.87%), disease severity (.. View more»
