Study on the control of peanut root rot by seed coating agent
In this study,two peanut varieties with high susceptibility to root rot were used as test materials to evaluate the effects of eight seed coating treatments on peanut emergence and seedling growth and the control effect on root rot.The objective was to identify seed coating agents that exhibited high seedling emergence rates and effec-tive disease prevention.Field efficacy trials for controlling root rot were conducted using seed coating methods,with untreated seeds serving as the control(CK).The results indicated that all seed coating treatments promoted seedling emergence and plant growth,leading to reduced yield losses.The disease control efficacy ranged from 11.42%to 36.94%and 17.53%to 34.01%for the two peanut varieties,respectively.The main stem height,seedling emer-gence rate,and yield showed a significantly negative correlation with disease severity index,while exhibiting a sig-nificantly positive correlation with disease control efficacy.The seed coating agent ZYJ1 was found to effectively control peanut root rot,contributing to seedling vigor,reducing disease severity,and promoting increased yield.It demonstrated good efficacy in the prevention and control of root rot in peanuts.
