14
Bio-control Agent Being Considered for Introduction to Australia A rust fungus Host-range testing may take two or three more years to complete
15
Boneseed Leafroller in NZ Releases: 2007-2008 12,500 Larvae 3080 Adults 36 Sites Establishment North Island: looking fairly promising South Island: not recovered after winter
21
Boneseed rust: Highly promising biocontrol agent Witches’ broom symptom Spore containing pustules on leaf
23
Host-range Testing of the Boneseed Rust Began in 2007 in South Africa. Intracellular vesicle Penetration point Basidiospore Detached leaf assay
24
Whole plant inoculation trial, to run for 3 years - needed for witches’ broom symptom development
25
Stemphyllium/leaf roller synergy? -tip dieback
