Lasiodiplodia iraniensis: new host and distribution

Scientific Name: Lasiodiplodia iraniensis

Describer: Abdollahzadeh, Zare & A.J.L. Phillips

Common Name: nan

Title: Lasiodiplodia iraniensis: new host and distribution


Significance: Lasiodiplodia iraniensis causes disease, including cankers, dieback, and gummosis, in economically important plants, such as Citrus spp., Mangifera indica (mango) (Al-Sadi et al., 2013), Juglans sp., Eucalyptus sp. (Abdollahzadeh et al., 2010), as well as Salvadora persica (Marques et al., 2013), and Bougainvillea spectabilis (Li et al., 2015). It has been reported from Brazil (Marques et al., 2013), Iran (Abdollahzadeh et al., 2010), Oman (Al-Sadi et al., 2013), China (Li et al., 2015), and Australia (Sakalidis et al., 2011).

Issues of Concern: In a recent publication, Lasiodiplodia iraniensis was shown to be highly pathogenic on Anacardium occidentale (cashew) trees in Brazil (Netto et al., 2016). This is the first report of Aoccidentale as a host of Liraniensis. Two other recent publications report Liraniensis from Peru, where it was isolated from mango (Rodríguez-Gálvez et al., 2016) and from South Africa, where it was isolated from Sclerocarya birrea (marula) trees (Mehl et al., 2016). These are the first reports of Liraniensis in Peru and South Africa.
