![]() 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. ![]() In some cases, a fungicide applied by a licensed professional will help reduce Ascochyta and speed up recovery.Ascochyta blight disease is a major problem in faba bean ( Vicia faba L ) production that causes 90% to 100% yield loss. The lawn can come out it without treatment but will take 2-3 weeks or longer. The areas around can be all bleached and yellow in appearance. It dies back from the tips first and spreads downward. The start of Ascochyta looks like the top 1/3 of the blade of grass has been bleached and appears pinched. It resembles drought stress but the damage is usually restricted to the leaves and the crowns and roots are not killed off. This is especially noticeable after mowing, sometimes leaving stripes in the turf. Ascochyta erupts very fast and it looks like the lawn is bleached or turning to straw. Because of all of mother nature’s moisture people have turned their sprinklers off and leave them off too long, coupled with a few days of hot and dry weather conditions contributes to an Ascochyta outbreak. Here in Northern Colorado we have been receiving a lot of rain, this should be good for your lawn, right? A significant increase in temperature, following a lot of rain in a short amount of time, is one of the factors that can trigger an outbreak of Ascochyta in Kentucky Bluegrass.
