Garlic rust which is caused by Puccinia allii is the most common and economically important foliar disease. Assessing the relationship between rust and yield loss of a given disease on a specific crop serves to know the effect of a given disease on specific crop directly on it yield. The objective of this study was to manage garlic rust through fungicide, and determine the extent of yield losses. Field experiments were conducted to evaluate theeffects of systemic fungicide (Natura) spray at rates (0.25, 0.5, and 0.75 L/ha) and frequencies of application (7, 14, 21, 28 days) with unsprayed control. The treatments were tested for their effects on severity and yield and yield components of garlic. The field experiment fungicide treatments were depicted different severity levels that resulted in different garlic yield losses. The final levels of severity were about 89.9% at MWRRS an.. View More»
