In present study, we followed the two strategies for efficient disease management practice to control rust of field peas in the Tarai region of Indo-Gangetic plains of India. This primarily included the assessment of the meteorological factors affecting the disease severity (DS) to assist in designing the superior disease models and simultaneously evaluated the relative impact of effective botanicals with comparison to frequently used extremely harmful fungicides on pea rust severity. The study revealed the high positive correlation between rust DS and average maximum temperature. Conversely, minimum relative humidity (RH) has shown a highest negative correlation with DS, followed by maximum RH, whereas rainfall exerted no effect. Likewise, regression analysis also confirmed the maximum temperature as a most important disease promoting factor followed by minimum temperature and minimum RH. To assess the effective and efficient disease control measures, we evaluated the actual impact of fungicides and botanicals. Among fungicides, propiconazole (tilt) treatment was found most effective among others in reducing the DS (62.27%) and improving the grain yield, whereas in botanicals, neem extract was observed best in minimizing DS (64.26.%) and achieving higher grain yield. In addition, treatment of 10% of botanicals spray was optimized as best optimum concentration for disease control. Thus, the disease model based on studied meteorological factors and use of botanical of environmental friendly and economic properties, could serve as efficient alternatives in pea rust disease management in future.
