Abstract

Mungbeans (Vigna radiata and Vigna mungo) and peanuts
(Arachis hypogaea) are important summer pulse crops in
northern New South Wales and Queensland. Mungbeans are grown as a short season, often opportunistic, crop from
northern New South Wales to central Queensland. The
bacterial diseases tan spot (caused by Curtobacterium
flaccumfaciens pv. flaccumfaciens) and halo blight
(Pseudomonas savastanoi pv. phaseolicola) and the fungal
disease powdery mildew (caused by Podosphaera fusca)
commonly occur at damaging levels on mungbean crops in
all regions. Peanuts, traditionally grown as a non‐irrigated
crop, are being increasingly grown under irrigation and in
the sugarcane farming systems of coastal Queensland. Rust
(caused by Puccinia arachidis) and late leaf spot (caused by
Mycosphaerella berkeleyi) cause significant yield losses in
these areas. Management of the important foliar diseases
of mungbeans and peanuts is being achieved through the
integration of different strategies, with resistance playing a pivotal role for all of them. Targeted fungicide applications also play a key management role for both peanut diseases and for powdery mildew on mungbeans, while the use of seed with minimal contamination levels is important for the mungbean bacterial diseases. For both pulse crops, new varieties with improved resistance to these important foliar pathogens combined with other practices will improve their management in the future.
