Diseases of Edible Oilseed Crops

Abstract

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.

A Susceptible Scion Reduces Rootstock Tolerance to Ralstonia solanacearum in Grafted Eggplant

“…There may be a specific interaction between the scion and rootstock, and a grafted plant always maintains the exchange of substances through the xylem and phloem [45], in which disease-related substances (some toxic proteins) in the rootstock are transmitted upwards. If some substances (defense factors) from the scion are conducted downwards over time, the rootstock suffers weakened disease tolerance [46,47].…”

Molecular characterization of disease resistance in Brassica juncea – The current status and the way forward

“…For example, sclerotinia stem rot and alternaria leaf blight are particularly severe on B . juncea in India (Chattopadhyay et al, 2015; Saharan et al, 2016), while white rust is particularly important in Canada (Saharan and Verma, 1992; Katiyar and Chamola, 2003; Pradhan and Pental, 2011), and India (Saharan and Verma, 1992; Singh et al, 2015, Saharan et al, 2016). In Australia, blackleg and sclerotinia have been identified as the most destructive diseases for oilseed‐ and vegetable‐type mustards (Murray and Brennan, 2012; Uloth et al, 2013, 2014, 2015a, 2015b; Van de Wouw et al, 2016).…”

“…We outline a guide for further discovery and identification of resistance genes that can be used for substantial improvement in disease management for B. juncea worldwide.
