One ISR-promoting PGPR product temporarily approved for use by the USEPA was Bacillus mycoides isolate J [61], a strain of a ubiquitous soil microorganism. This PGPR was once approved for experimental use in 2006 for controlling Cercospora leaf spot (Cercospora beticola) on sugar beets, but the approvals have since expired. To date,...

The beticolins (ascertained structures shown, bO, 2,4,6,8,13,1, 3, and 1063-1 70, respectively. Fig. 13.29) are a fascinating fantily of closely related non-host-specific mycotoxins produced by several strains of Cercospora beticola, a fungus responsible for cercosporiosis, a leaf spot disease of sugar beet Beta vulgaris) (680-683).

A Phytoalexin Betavulgarin (2 -Hydroxy-6,7-Methylenedioxy-5-Methoxyisojlavone, 14) from Beta vulgaris by Cercospora Beticola... 

In 1973, a group of Department of Chemistry, Colorado State University, USA examined phytoalexins induced in Beta vulgaris leaves with Cercospora leaf spot of beet caused by Cercospora beticola infection. Generally, phytoalexins are produced by de novo synthesis in higher plants after the infection of fungal organism [38]. 

Betavulgarin (2 -hydroxy-6,7-methylenedioxy-5-methoxyisoflavone, 14) (Figure 5) was identified together with a flavanone 2 ,5-dimethoxy-6,7-methylenedioxyflavanone (15) (Figure 5) from the infected sugarbeet leaves by Cercospora beticola [39]. 

Candida albicans, Phytophthora infestans, Cercospora beticola (I856), use as algicide and molluscicide with low toxicity (1856).
