Pecan diseases
Pecan diseases and health risks in South Africa
A collaborative project, launched in 2017 between SAPPA and the University of the Free State (UFS) is focussing on the study and distribution of pecan diseases in South Africa:Part 1:- Pecan Scab
- Black blotch and die-back
- Alternaria black spot
- White and brown rot
- Black lesions on nuts (Chaetomium species)
- Overall decline of pecan trees
- Fungi associated with the shot hole borer
Polyphagous Shothole borer and fungus infesting Pecan trees
A collaborative research project between SAPPA and FABI started in 2018 investigating the PSHB on pecan nut orchards.
The project is on understanding the seasonal patterns as well as the rate of spread of the beetles, and also studying the long-term effects of the fungal infections caused by the PSHB
