![]() Its world average grain yield productivity is around 1.81 t ha −1. Worldwide faba bean production occupied 2.43 million hectares and 4.40 million tons. revealed that faba bean can be used as a common breakfast food and major source of plant-based protein in the Middle East, Mediterranean region, China, and Ethiopia. Introductionįaba bean ( Vicia faba L) plays a key role in biological nitrogen fixation process by adding up to 40% soil organic nitrogen available for the next crop. Therefore, the use of EH0 variety, with two times Mancolaxyl spray frequency application, at early growth stage and the onset of the disease is suggested as an agronomic management option, in Northwestern Ethiopia. The linear regression analysis result ( R 2) indicated that the variation in average grain yield of EH0 and local susceptible varieties, due to the mean area under the disease progress curve, was 64.50% and 68.64%, respectively. Greater total return (195,938 Ethiopian birr ha −1), net return (101,761.3 Ethiopian birr ha −1), and net benefit (34,768.17 Ethiopian birr ha −1) were obtained by EH0 variety, in two times Mancolaxyl treatment. Application of fungicide significantly increased plant height, stem girth, pod per plant, grain yield, and harvesting index ( ) over untreated plots. The results showed that area under disease progress curve, percent severity index, disease progress rate, and percent disease incidence had strong mean significant differences ( ) between treated and untreated plots. ![]() The economic data obtained from the field experiment was analyzed using the partial budget analysis method. An analysis of variance was performed for disease, yield, and yield related and plant growth parameter data, using the Statistical Analysis System (SAS, 2003) version 9.1.3 software. ![]() The field experiment was arranged in a randomized complete block design with factorial combinations of variety, fungicide, and spray frequency levels in three replications. For the assessment of disease management, a total of 21 treatments were used, which comprised three fungicides, three spray frequencies, two varieties, and control. A field experiment was conducted to evaluate the efficacy of three fungicides with three spray frequency levels against Ascochyta blight disease of faba bean varieties. Kentucky bluegrass, tall fescue, and perennial ryegrass.Ascochyta blight disease is a major problem in faba bean ( Vicia faba L ) production that causes 90% to 100% yield loss. Grasses susceptible to ascochyta leaf blight: Over-cutting of lawns can exacerbate ascochyta leaf blight by giving it more open cuts to infects. Stretches of hot, dry weather right after a period of unusually wet soil conditions (usually a result of overwatering or large amounts of rainfall over an extended period of time. Can also be white banding,or could be entirely collapsed and shriveled Healthy leaves are interspersed with infected leaves.īlades will appear bleached from the tip to about 1/3 of the way down the leaf.īetween the bleached are and the green of the rest of the blade can be a dark brown-purple banding. Large areas of grass will turn straw-colored and appear dead. Symptoms of ascochyta will often occur quite rapidly. Symptoms of ascochyta leaf blight include: Skilled technicians can easily identify ascochyta apart from other issues NOTE: Ascochyta leaf blight can often be confused with heat stress, dollar spot, white grub damage, and the burning of the lawn by chemicals.
