Incidence of white rot in apple fruits with and without wounds

The relationship between damages of wounds, fruit fly and the incidence of white rot (Botryosphaeria dothidea), inoculated artificially in two apple genotypes was studied. The experiment was carried out at the laboratory of Entomology at Epagri/Caçador Experimental Station, during the 2005/2006 season. 'Catarina' (group 'Fuji') and the selection M-13/00 (group 'Gala') were tested with the following treatments: (1) fruit submitted to fruit fly; (2) fruit submitted to wounds by needle; (3) fruit without wounds; (4) fruit without wounds sprayed with distilled water (control). The treatments 1, 2 and 3 were inoculated with B. dothidea. The experiment was conducted under completely randomized design with four replications of four apple fruits each. The frequency of lesions of white rot was larger on cv. Catarina compared to M-13/00. Fruit wounds stimulate the establishment and the development of white rot lesions.
