Notas Científicas Resistance to Fusarium dry root rot disease in cassava accessions
The objective of this work was to identify sources of resistance to dry root rot induced by Fusarium sp. in cassava accessions. A macroconidial suspension (20 μL) of 11 Fusarium sp. isolates was inoculated in cassava roots, from 353 acessions plus seven commercial varieties. Ten days after inoculation, the total area colonized by the pathogen on the root pulp was evaluated by digital image anal...
متن کاملresponse of iranian local and improved genotypes of melon and musk melon to charcoal rot disease caused by macrophomina phaseolina
melon and musk melon are grown widely in warm and moderate climate regions of the world as well as iran. these crops are attacked by several fungal pathogens including macrophomina phaseolina which causes charcoal rot disease at different growth stages and reduces the yield remarkably. fungicide application and other control methods have not been successful in control of charcoal rot and utiliz...
متن کاملField screening of safflower genotypes for resistance to charcoal rot disease
Nineteen safflower genotypes (Carthamus tinctorius L.) that originated from different geographical regions were screening for their response to infection with Macrophomina phaseolina, the charcoal rot pathogen at the research farm of Gorgan University of Agricultural Sciences and Natural Resources, Gorgan, Iran, in 2005. The plants were evaluated for length and width of necrotic lesion at the e...
متن کاملStudy of interaction between salinity and charcoal rot diseases of melon (Macrophomina phaseolina) in Semnan and Garmsar
Charcoal rot diseases of melon caused by Macrophomina phaseolina is one of the most important diseases of melon occurring in regions with variable climate. Reduction of yield of melon by this disease has been reported up to 100% in some of Garmsar field. Salinity which can cause the important trouble in plant metabolism and nutrition is present in Semnan and Garmsar areas. Melon is susceptible ...
متن کاملReaction of Cauliflower Genotypes to Black Rot of Crucifers
This study aimed to evaluate six cauliflower genotypes regarding their resistance to black rot and their production performance. To do so, it was conducted two field experiments in Ipameri, Goiás, Brazil, in 2012 and 2013. It was used a randomized block design, with four replications (total of 24 plots). Each plot consisted of three planting lines 2.5 m long (six plants/line), spaced 1.0 m apar...
