Objective]Early leaf spot disease and web blotch disease are the most serious disease in peanuts. The symptoms of these two diseases always occur on the same plant in the late growth stage of the peanut, and cause serious yield losses in peanut production. The objectives of this study are to evaluate the factors that influence the infection probability and latent period of Cercospora arachidicolaandPhoma arachidicola after mixed infection on peanuts, investigate the interactions between disease and host plants, and provide a basis for formulating comprehensive control of more diseases and pests on the same host.[Method]C. arachidicolaandP. arachidicolawere inoculated on susceptible cultivar, Baisha1016. In the field, different plant growth stages, inoculum concentration and leaf wetness period were constructed. The influences of the mixed infection ofC. arachidicola andP. arachidicola on the infection probability and latent period were analyzed.[Result]When C. arachidicola andP. arachidicola were inoculated alone, the infection probability of both pathogens were increased with the extension of the growth stage. Specifically, the infection probability for the different growth stage of peanut was: early flowering stage展开▼
