Efi cácia versus viabilidade econômica do controle químico e genético da ferrugem da folha em trigo.Ciência Rural, v.43, n.7, jul, 2013.
ABSTRACTThe objective was to evaluate the effi ciency and the economic viability of the fungicides application, under a randomized block design in three factorial arrangement with three replicates, were utilized two cultivars ('BRS 220' and 'Vanguarda')
Reação de genótipos de nectarina (Prunus persicavaABSTRACT -Genetic resistance to disease can be seen as progress in the production of all crops, and sources of resistance have to be reported, thus helping improvement programs. This study aimed to evaluate the resistance of nectarine genotypes to leaf rust and shot hole, as well as to correlate the severity of the diseases with premature defoliation. Three genotypes of the nectarine were evaluated in a randomized block design with ten replications. Based on the results, the genotype Bruna proved resistant to shot hole and susceptible to leaf rust, while the genotype Sunripe was resistant to leaf rust. FLA 9-15N was moderately susceptible to leaf rust. There was correlation between leaf-rust severity and defoliation only.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
