Resposta de cultivares de trigo (Triticum aestivum L.) ao controle químico das principais doenças fúngicas da cultura

Abstract: Leaf rust, leaf spot or brown spot and powdery mildew, caused by Puccinia recondita tritici, Bipolaris sorokiniana and Blumeria graminis tritici, respectively, are wheat diseases that may severely decrease crop yield. Several practices are recommended for the control of these diseases such as cultivar resistance, planting at a suitable time, and chemical control, without which the crop frequently becomes uneconomical. The objective of the present work was to evaluate, under field conditions, the response of si… Show more

“…This shows us that in years where the occurrence of diseases is high, even with the existence of gains with the application of fungicide, the grain yield is expressively reduced. The effect of years of cultivation on the occurrence of diseases in wheat, because of environmental variations, is also reported by other authors (Felicio et al 2004;Barros et al 2006;Ransom & McMullen 2008;Wegulo et al 2011). In this sense, Thompson et al (2014) suggest that the phytosanitary management is year/site specific, considering the expected yield potential, prices and predominant climatic conditions.…”

“…The variation in efficacy and responsiveness to fungicide application is mainly influenced by the relative air humidity, temperature, pathogen aggressiveness, resistance of the cultivar and the level of technological management adopted (Barros et al, 2006;Jørgensen & Olsen 2007;Loyce et al 2008;Wegulo et al, 2011;Thompson et al, 2014). Depending on the conditions of the environment, management and cultivars, losses ranging from 5.5 to 79% due to the occurrence of leaf fungal diseases were recorded (Ransom & Mcmullen 2008;Wegulo et al 2009;MacLeod et al, 2010;Tonin et al, 2013).…”

“…ex Desm. f. sp.trititici, é uma das principais doenças que afetam a cultura do trigo, podendo ocorrer em diversas regiões tritícolas de diversos países, causando reduções significativas na produção de grãos, principalmente em anos favoráveis à sua ocorrência (Chaves e Barcellos, 2006;Barros et al, 2005). Diversos métodos de melhoramento, tais como hibridações com e sem irradiação e hibridações interespecíficas (Lobato et al, 2007) têm sido utilizados com sucesso na obtenção de genótipos resistentes a esse patógeno.…”
