Effect of treatment of melon fruits (Cucumis melo L.) with different calcium sources on rot caused by Myrothecium roridum.

Solutions of CaCl2, CaSO4, CaCO3 and Ca(NO3)2, with 11% Ca+2 were used to evaluate the effect of different sources of calcium on melon fruit rot caused by Myrothecium roridum. Fruits of cultivar Valenciano, previously wounded, were immersed in each solution for 10 minutes. After air drying the fruits were inoculated with 2 isolates of the pathogen. Eight days after inoculation the areas with fruit rot symptoms were determined. An in vitro assay was conducted to determine if the substances used in fruit treatments have a direct effect on pathogen growth and sporulation. Among all sources of Ca+2 tested, only CaCl2 reduced the disease (66% compared with the control). Since growth and sporulation of the pathogen were not affected by the substances in vitro, this control was considered as an indirect effect of the calcium source on the development of this fungus on melon fruits.
