ascochyta rabiei is one of the devastaining fungi pathogens of chick-pea (cicer arietinum l.) crops. in the present investigation, forty-two iranian isolates of ascochyta rabiei fungi (including highly, weakly and moderate virulent isolates), whose pathogenisities were determined previously, were studied. polygalacturonase is a main factor in the initiation of ascochyta blight disease. therefor...

The antimycotic potential of Datura metel (syn. Datura alba Nees.) was investigated in vitro against Ascochyta rabiei, the cause of chickpea blight disease. The pathogen was exposed to various n-hexane concentrations (1, 2, 3 and 4% w/v) of shoot and root extracts of D. metel using poisoning food technique. All the employed concentrations of both root and shoot extracts significantly suppressed...

The faba bean (Vicia faba) is a temperate grain legume, that regaining interest due to the high demand for food and feed uses environmental services provided. parasitic weed broomrape (Orobanche crenata) appears as major constraint agricultural production in Mediterranean Basin. yield stability can be managed by adjusting agronomic practices breeding adaptation. In this study, we compared perfo...

Ascochyta blight is one of the most common diseases that threaten pea and cause severe crop losses. The research concerned with integrated control this disease by studying effect biological agents inorganic salts, planting dates distances, especially in light climate change impact these factors on spread disease. In study, two bacterial strains Bacillus megaterium Pseudomonas fluorescens as bio...
