Effect of Different Seed Coating Agents on the Control of Anthracnose in Cowpea Seedlings
摘要
Abstract
To screen the optimal seed coating formulation for controlling anthracnose in cowpea seedlings,this experiment investigated the natural incidence rate of anthracnose in cowpea seedling in three locations including Xinmin Liaoning.Ten seed coating agents were applied to cowpea seeds at a coating agent-seed ratio of 1∶200.The effects of different seed coating agents on seedling emer-gence rate,seedling growth,and control efficacy against cowpea seedling anthracnose were determined.The results showed that the natural incidence rate of anthracnose in cowpea seedlings was the highest in Xinmin Liaoning,reaching 68.74%.Most seed coating a-gents were unfavorable for the accumulation of aboveground biomass in cowpea seedlings but promoted the accumulation of under-ground biomass.Except for the 10%metalaxyl-M seed coating agent and the 9%pyraclostrobin·fludioxonil·thiamethoxam seed coat-ing agent,which significantly reduced the seedling emergence rate to 73.33%and 91.67%after one year of storage,respectively,the other dressings maintained rates above 95%.The 25 g·L-1 fludioxonil seed coating agent had no adverse effects on cowpea seedling growth or the emergence rate after one-year storage,with an anthracnose incidence rate of 0%,making it the optimal seed dressing formulation for controlling anthracnose in cowpea seedlings.In summary,anthracnose pathogens are commonly carried by cowpea seeds,and seed coating treatment of cowpea seeds with seed coating agents can effectively prevent and control anthracnose during the seedling stage.关键词
