Abstract

In the study of the effect of solar radiation on the incidence of anthracnose (Colletotrichum acutatum) in the flowering stage and sheath radiation in the local San Gabriel genotype (Lupinus mutabilis), its seeds were irradiated at times of 45, 60 and 90 minutes, using a homemade radiation stove Solar radiation in the 60 and 90 minute times decreased the percentage of anthracnose infection compared to the absolute zero-minute control and the Vitavax chemical treatment; The 60 minute solar radiation treatment showed a higher germination percentage compared to the other treatments. Seeds irradiated at 90 minutes of sun exposure decreased the incidence of C. acutatum, radiation that resulted in a smaller area under the disease progress curve throughout the crop cycle. Plants that came from irradiated seeds with respect to lower severities compared to seeds without treatment and with chemical treatment. The seeds applied to a radiation of 90 minutes of sun exposure obtained an average of 5.27 infected pods, while a time of 60 minutes of solar radiation 65.27 per plant. A yield of 1110.25 kg / ha was obtained in seeds irradiated at 60 minutes of sun exposure in the local San Gabriel genotype with a cost-benefit ratio of 1.98
