“…Chen and Fernando (2006a) reported five pathogenicity groups (PG1, PG2, PG3, PG4, and PGT) of L. maculans on the basis of a series of inoculations on canola cultivars (Westar, Glacier, and Quinta) in western Canada and the United States. The PG3 and PG2 of L. maculans have also been reported on winter rape in Hungary (Szlavik et al 2006) and Iran (Mirabadi et al 2009), respectively. Nine races of L. maculans have been described and designated as AvrLm 1-9 (Mitrovic and Trkulja 2010).…”

AgriculturalSciences. He has more than 22 years of research experience in oilseed crop disease management and has significantly contributed in the areas of understanding the host-pathogen interactions, epi demiology, and integrated disease management in sunflower, safflower, sesame, peanut, and rape seed-mustard crops. He has published more than 70 peer-reviewed research papers and 4 books. Dr. Chattopadhyay has to his credit several academic awards and one patent. His significant research achievements include the development of Fusarium wilt-resistant genotypes in safflower, the iden tification of genotypes of Brassica juncea resistant to a mixture of isolates of Albugo candida, the development of a biocontrol agent formulation to reduce the use of fungicides in the management of major diseases of oilseeds (Brassica), and seed treatment (and foliar application) of aqueous bulb extract of Allium sativum for the management of major foliar diseases (Alternaria blight, white rust, powdery mildew, and Sclerotinia stem rot) of mustard.

“…As has previously been demonstrated by Huang et al (2001), using a combination of pathogenicity (Zamanmirabadi, Rahnama, & Esmaeilifar, 2009; Zamanmirabadi, Rahnama, et al, 2010) and morphological analyses (Zamanmirabadi et al, 2016), it has been shown that it is possible to distinguish Iranian populations of L . maculans and L .…”

“…The first PGs of L . maculans (PG2 and PGT), identified using cotyledon inoculation assays on the differential set of Westar (no R genes, susceptible control), Quinta ( Rlm1 , Rlm3 ), and Glacier ( Rlm2 , Rlm3 ), were recorded in the Mazandaran province in the north of Iran, in 2009 (Zamanmirabadi, Rahnama, Esmaeilifar, 2009; Zamanmirabadi, Rahnama, Mehdi Alamdarlou, et al, 2009). Eight years after the first report of PG2 and PGT, PG3 and PGT groups were detected in Golestan province (Vakili‐Zarj et al, 2017a).…”

In order to make informed decisions on disease management, it is important to know what races are present and in which areas they are most likely to be encountered.…”

Current progress in studying blackleg disease (Leptosphaeria maculans and L. biglobosa) of canola in Iran: Where do we stand now?

et al. 2021

Blackleg, caused by a complex of Leptosphaeria species (L. maculans and L. biglobosa), is a fungal disease on Brassica species, especially important in canola (Brassica napus). Since the first report of L. biglobosa in Iran in 2007 and L. maculans in 2008, both species are now of major importance in Iran affecting 10 provinces and 30 regions, with a higher prevalence in the northern provinces of Mazandaran and Golestan. Despite the rapid progression of the disease and the emergence of new Leptosphaeria races in Iran, the research into this pathogen has not progressed at the same rate and is limited to phenotypic characterization studies, pathogenicity research, and to a lesser extent, disease management research. Given the rapid increase in canola cultivation in Iran and changes in the genetic diversity of the pathogen populations, it is likely that blackleg disease will increasingly become a severe threat to Iran’s canola production. Therefore, systematic and prospective studies, along with fundamental research on the pathogen's biology, epidemiology, and genetic diversity, would provide critical information for the development of disease management strategies. Here, we review the research that has been carried out to date on blackleg disease in Iran and describe the extent of progress towards disease control, especially in disease‐prone regions.
