植物免疫调节剂对玉米大斑病病害控制及田间产量的影响
Effects of Plant Immunomodulators on Control of Maize Large Spot Disease and Field Yield
摘要
Abstract
To evaluate the disease resistance and yield-enhancing effects of plant immune regulators on maize,three plant immune regulators were investigated for their impacts on maize growth,disease control,and yield in field trials.The results showed that the disease severity index of maize under all three treatments was significantly lower than the blank control group.Among them,the Puliwei AS treatment demonstrated the lowest leaf disease incidence rate with a severity index of 10.49,achieving the best prevention efficacy at 73.27％.Yield measurements indicated no significant difference between treatments,all exceeding those of the blank control and chemical agent control.Tianzhijiao AS treatment yielded the highest comprehensive indicators,followed by Puliwei AS treatment,with yields reaching 997.16 and 863.36 kg·(667 m2)-1.The combined prevention efficacy results revealed that Puliwei AS provided superior disease control and yield enhancement.关键词
