Haste verde e retenção foliar na cultura da soja

Abstract: RESUMOPalavras-chave adicionais: fungicidas, nutricão, soja louca, pragas, cultivares.Green stem in soybean is a syndrome that makes the primary and the seconda ry stems of soybean rema in green even a fter the seed physiological ma turity. Lea f retention is the maintena nc e of g reen leaves for a longer period a fter seed matu ra tion. Its occu rrence in soybea n crops has been attributed to the use of some fungicides to control the lea f disea ses complex in soybea n, especially soybea n r u st a n d l a t… Show more

“…Green stem corresponds to the maintenance of green primary and secondary stems, and leaf retention is the absence of leaf loss, even after physiological seed maturity (Silva et al. ). Stink bug attacked soybean plants at the reproductive phase may lose grains and pods and the stress causes the retention of green leaves and stems.…”

“…Moreover, the attack also allows the transmission of pathogens, such as the yeast Eremothecium coryli , delay in the physiological maturity or leaf retention, impairing mechanical harvesting of the crop (Gazzoni and Moscardi ; Silva et al. ). The losses caused by the stink bug complex may reach up to 125 kg ha −1 , considering the presence of a single stink bug per square meter (Guedes et al.…”

“…Em genótipos de feijão-fava cultivados em vaso e em condições de folhas destacadas no estado do Piauí, Cavalcante (2012) ao avaliar trinta subamostras de feijão-fava em condições de folhas destacadas constatou resistência moderada em seis genótipos enquanto dois genótipos foram considerados altamente resistentes (AR) UFPI -251 e UFPI -673 no sétimo dia após a inoculação do fungo. Esses resultados demonstram a importância de se continuar avaliando subamostras de feijão-fava de forma a contribuir em programas de melhoramento em busca de material resistente a C. truncatum.…”

“…No gênero Phaseolus destacam-se o mofo branco (BOECHAT et al, 2014), podridão de raiz e do colo (SILVA et al, 2010), manchaangular (GARCIA & ROMEIRO, 2011) e antracnose (CAVALCANTE et al, 2012). A antracnose é uma doença causada por fungos do gênero Colletotrichum que, em condições de elevada umidade e temperatura, predominante na região Nordeste do Brasil, e favoráveis ao patógeno, pode provocar perdas de até 100% da produção (SILVA et al, 2013). Em feijão-fava, é causada pela espécie Colletotrichum truncatum e os sintomas se caracterizam como manchas avermelhadas inicialmente observadas ao longo das nervuras, na face inferior das folhas e sobre hastes e pecíolos jovens.…”

“…It should also be emphasized that the causes associated with the presence of green pods in soybean grains are diverse (Silva et al, 2013;Harbach et al, 2016), for instance, the type of plant growth (Boudreaux & Griffin, 2011). Moreover, green pods during harvest can be threshed by the threshing mechanisms of the harvester, culminating in the release of immature grains in the harvested mass (Sinnecker, 2005).…”
