“…Genetic and pathogenic variability among the isolates of X. campestris pv. campestris has been identified by several workers (Gaetan and Lopez 2005, Miguel-Wruck et al 2010, Raghavendra et al 2013. A DNA probe has been developed for rapid identification of strain of this pathogen in plant tissues (Shih et al 2000).…”

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.

“…Among the seedlings that are produced on a large scale, the families Brassicaceae (broccoli and mustard) and Asteraceae (lettuce) stand out. The first two species have the highest economic relevance (Miguel-Wruck et al 2010) and the third is the most consumed leafy vegetable crop in the country (Freitas et al 2013a).…”

The carbonized rice husk (CRH) is an agro-industrial residue with great potential for use in mixtures with other substrates for the production of vegetable seedlings. Thus, the purpose of this study was to evaluate the effect of the addition of CRH to the commercial substrate for the production of greenhouse seedlings. The evaluated vegetables were lettuce, broccoli and mustard, cultivated in polystyrene foam (Styrofoam®) trays. Five treatments were evaluated: 100% of the commercial substrate (CS); 25% of CRH + 75% of CS; 50% of CRH + 50% of CS; 75% CRH + 25% CS; and 100% CRH, in a completely randomized design with twelve replicates. The substrates were evaluated for their physical and chemical characteristics. The morphometric evaluations were: number of leaves per plant, plant height, shoot fresh matter yield, root length, and shoot and root dry matter yield. The data were submitted to regression analysis, and the homogeneity of the variance between the experiments was confirmed by the Cochran test. With the addition of CRH to the substrate, there was an increase in total porosity and P content and a reduction in density, water holding capacity, cation exchange capacity, electrical conductivity, and N, K, S, Ca and Mg contents. The carbonized rice husk added to the commercial substrate is a viable alternative for the production of lettuce, broccoli and mustard seedlings. The quality of the vegetable seedlings was higher when there was a 25% CRH + 75% CS mixture.

“…Miguel-Wruck et al (2010) observaram relativo grau de especificidade entre 33 isolados obtidos de várias regiões do Brasil e do exterior, inoculados em oito espécies de brássicas e alguns isolados não causaram doença em uma ou mais das brássicas inoculadas.Assim, é importante identificar o patógeno por meio de primers específicos e estudar sua variabilidade genética por meio de primers universais utilizando a ferramenta de PCR.Entre os 34 isolados bacterianos, 33 foram amplificados com o par de primers XCF/XCR específico para Xcc, gerando um único fragmento de aproximadamente 535 pb, confirmando a identidade da bactéria como Xanthomonas campestris pv. campestris.…”
