The disease causes a significant yield loss and imposes health threats to humans and animals by producing mycotoxins. In this review, we update our understanding of the pathogen, including the disease cycle and infection strategies, the decoding of the U. virens genome, comparative/functional genomics, and effector biology. Whereas the decoding of the U. virens genome unveils specific adaptations of the pathogen in successfully occupying rice flowers, progresses in comparative/functional genomics and effector biology have begun to uncover the molecular mechanisms underlying U. virens virulence and pathogenicity. We highlight the identification and characterization of the produced mycotoxins and their biosynthetic pathways in U. virens.The management strategies for this disease are also discussed. The flower-specific infection strategy makes the pathog...

Four densities (10 4 , 10 6 , 10 8 and 10 10 spores/g of soil) of each fungus were used. The results indicate that all four inoculum densities of the two Trichoderma species suppressed the nematode reproduction and root galling; and increased the growth of tomato plants, compared to controls. Efficacy of both fungi increased as their inoculum densities increased. Generally, efficacy of T. harzianum was better than that of T. viride, especially at the highest used density (10 10 spore/g soil) which resulted in the best control.
