GENERAL INFORMATION

Description

A naturally occurring plant pathogenic fungi used to control Dodders (Cuscuta spp.)

Example pests controlled

Dodder (Cuscuta spp.)

Example applications

Soybean

Efficacy & activity

Appearance and life cycle

The spores colonise dead and injured plant tissues which subsequently disperse over short distances through rain splashing and irrigation. Lesions are produced on plant parts which darken with age and form a characteristic concentric ring pattern
