Abstract | ||||
Legume crops (faba bean, lentil, chickpea and lupin) are important human food and animal feed in Egypt. Several soil-borne fungi at- tack the roots of these crops and cause root-rot and wilt diseases. Fusarium oxysporum. and Rhizoctonia solani are the most destructive fungi attacking such plants. Under greenhouse conditions, four biocontrol agent namely Trichoderma harzianum, Gliocladium vireos, Paecilomyces farinasus and Bacillus subtilis and the fungicide Rizolex T, were tested for controlling root-rot/wilt diseases of the formentioned crops at Giza Res. Station in 1999/2000. T.harzianum and Gliocladium virgins were the most effective bioagents in reducing the root-rot/wilt diseases caused by Fusarium oxysporUrn and Rhizoctonia solaniin faba bean, chickpeaand lupin whereas T.harzianum and Bacillus subtilis were effective in lentil. The percentage of survival plants were 86.7%; 80.0%; 80.0%; 83.3%; 80.0% and 73.3%. respectively. The respective values were 68.3% 56.7% in lentil as compared with the controls 26.7%, 30.0%. 30.0% and 20.0%. respectively. | ||||
