Control Efficacy and Economic Benefit Analysis of Different Fungicides on Potato Late Blight
摘要
Abstract
Late blight caused by Phytophthora infestans is a devastating disease in potato production,occurring globally and causing severe damage.To scientifically evaluate and select the best fungicides for controlling late blight in the current market,a two-factor split-plot design was adopted to investigate the field control effects of 10 fungicides on the late blight of'Dingshu 7'(moderately resistant)and'Xindaping'(susceptible),and to conduct economic benefit evalua-tions.Treatment with eugenol 20%,mandipropamid 23.4%,and oxathiapiprolin 10%all exhibited significant control effects and excelled in total income,economic benefit,and output-input ratio,outperforming the other treatments.Among them,the three control effects of eugenol 20%on'Xindaping'were all above 73.00%,and it also increased the yield of'Dingshu 7'and'Xindaping'by 26.94%and 31.07%,respectively,with a significant yield-increasing effect.Under the eugenol 20%treatment,the total income of'Dingshu 7'and'Xindaping'was 122 525 Yuan/ha and 73 721 Yuan/ha respectively,with economic benefits of 101 240 Yuan/ha and 50 757 Yuan/ha,and output-input ratio of 5.76 and 3.21.In conclusion,eugenol 20%exhibits superior efficacy in disease control,substantial yield improvement,and considerable economic returns,thereby emerging as the most suitable field application for the management of potato late blight.As alternative options,mandipropamid 23.4%and oxathiapiprolin 10%demonstrate effective control of potato late blight and may be considered for use under specific conditions.关键词
