						 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»
