Abstract
The collapse of melon caused by a complex of fungal pathogens, including Monosporascus cannonballus, is one of
the most destructive diseases worldwide. The goal of this research was to investigate integrated and sustainable
control strategies against M. cannonballus in Central Italy. More specifically, we aimed to investigate occurrence
of melon collapse in greenhouse grown and to assess control strategies against M. cannonballus. Moreover we
aimed to observe the effects of compost amendment on sudden wilt and the influence of the endomycorrhizal
fungus Glomus intraradices (AFM) on the development of M. cannonballus. The results confirm that the M.
cannonballus occurrence ranged from 24% to 30% of all the farms surveyed and that the measures built up in
melon producing area in Province of Viterbo are un-sustainable and effective only by few tools such as
fumigation and grafting on squash. Experiments under greenhouse conditions have shown that compost
amendment is capable to reduce the severity of collapse caused by M. cannonballus on melon. Moreover,
inoculation with AMF alone is not sufficient for the complete prevention melon collapse. Control of melon
collapse can be obtained with a sustainable and integrated strategy promoting fertility maintenance and
restoration of soil health.
