“…In contrast to that verified for common bean in the present study, for soybean, a higher chlorophyll content was found in comparison to the control, with application in seed treatment with pyraclostrobin + + methyl thiophanate + fipronil (Balardin et al, 2011), and application after V8 with picoxystrobin + cyproconazole (Roese & Lima Filho, 2010). In coffee plants, Paulo Junior et al (2013) also verified an increase in chlorophyll content with the use of pyraclostrobin, probably caused by the increase in cytokinin production, as these delay leaf senescence by preserving foliar proteins and chlorophyll, which consequently increases the green effect (Sampaio, 1998).…”

“…In soybean, 42 days after the emergence, plant height increased due to the application of pyraclostrobin + methyl thiophanate + fipronil in the treatment of seeds (Balardin et al, 2011). Notwithstanding, this product did not interfere with the height of bean plants in the present work.…”

“…Under water stress conditions, the application in common bean helps plants to overcome photosynthetic stress and oxidative stress, acting to maintain plant grain yield (Jadoski, 2012). In such conditions, soybean seeds treated with pyraclostrobin + + methyl thiophanate + fipronil have increases in grain yield of 57.8% in relation to the control, however under normal conditions of cultivation there are no additive effects (Balardin et al, 2011).…”

“…9, No. 9;2017 128 Absence of phytotoxic effect was also observed by Cunha et al (2015) and Balardin et al (2011), who evaluated the effect of seed treatment on the development of soybean plants, for the same variables studied. According to Conceição et al (2014), these results point out the efficiency of seed treatment, though in order to be considered effective; it must not have phytotoxic effect on the physiological quality of the seeds, as well as the development of the plants.…”

The purpose of this study was to evaluate the effect of different combinations of products applied through seed treatment, associated with the inoculation, in the development of soybean plants. The experiment was conducted in a greenhouse at Federal University of Lavras (UFLA). The experimental design was a randomized complete block, with four repetitions in a factorial 4 × 11, being four soybean cultivars and 11 combinations of products associated with the inoculation in the treatment of seeds. At the stage (R 1 ) it was evaluated: plant height, leaf area, foliar chlorophyll content, number of trifoliate leaves, dry shoot mass, dry root mass, root length, root volume, nodules total number, viable nodules total number, nodules dry mass and foliar nitrogen content. The combination of products in the treatment of seeds, do not present phytotoxic effects in the characters related to the development, except for dry matter of aerial part and root volume. The combination of products in treatment of seeds influences negatively the nodulation, especially in the treatments with presence of nematicide. The inoculation performed in isolation or combined with fungicide and insecticide (I+FI) maintains nodule levels.

“…Assim, a redução na síntese de etileno pode não ser o principal mecanismo pelo qual estrobilurinas interferirem no processo de senescência. Em outras espécies vegetais, como soja (AUGUSTI et al, 2010;FAGAN et al, 2010;TSUMANUMA et al, 2010;BALARDIN et al, 2011), batata (LOPES, 2011, pepino (AMARO, 2011) também foram observados efeitos fisiológicos benéficos após o tratamento com estrobilurinas.…”

ResumoHá relatos de que estrobilurinas, além de atuarem como fungicida, promovem benefícios fisiológicos às plantas. Assim sendo, o presente trabalho teve como objetivo avaliar o efeito de estrobirulinas na fisiologia de mudas de bananeira. Para tal, mudas micropropagadas da cultivar Grand Naine foram repicadas para vasos contendo substrato e mantidas em viveiro a 50% de sombreamento. O delineamento experimental foi inteiramente casualizado, com três tratamentos (água, azoxistrobina e piraclostrobina) e cinco repetições. As estrobirulinas foram aplicadas com pulverizador manual aos 15, 30, 45, 60 e 75 dias após a repicagem, na dose de 100 g i. a. ha -1 . A altura da planta, diâmetro do pseudocaule e a massa da matéria seca da parte aérea de plantas tratadas com estrobilurinas foram superiores às de plantas não tratadas. O efeito do tratamento com fungicidas foi diferenciado, sendo mais pronunciado nas plantas tratadas com piraclostrobina do que nas plantas tratadas com azoxistrobina. Plantas tratadas com piraclostrobina apresentaram área foliar, atividade da redutase do nitrato e teor de clorofila a e de nitrogênio total foliar superiores às plantas tratadas com azoxistrobina e água, que não diferiram entre si. As estrobilurinas afetaram a fisiologia das mudas de bananeira, com destaque para a piraclostrobina. Palavras-chave: Musa sp., efeito fisiológico, azoxistrobina, piraclostrobina AbstractThere are reports that strobilurin besides having a fungicide effect can promote physiologic benefits to the plants. However, this effect on banana plants was not studied yet. The objective of the present study was to evaluate the effect of strobirulins on the physiology of banana plantlets. For this purpose, cultivar Grand Naine banana plantlets were transferred to pots containing substrate and kept in a nursery with 50% shading. The experimental design was a completely randomized design with three treatments (water, azoxystrobin and pyraclostrobin) and five replications. The treatments were applied at 15, 30, 45, 60 and 75 days after transplanting at a dose 100 g a. i. ha -1 with manual spray. Plant height, pseudostem diameter, shoot dry matter in strobilurin treated plants were higher than the untreated plants, however, the effect of fungicide treatment was different, being the most pronounced effect of pyraclostrobin compared to azoxystrobin. Plants treated with pyraclostrobin had higher leaf area, nitrate reductase activity and chlorophyll content of leaf total nitrogen than the plants treated with azoxystrobin and water, which did not differ. Strobilurins affect the physiology of the banana plantlets differently, the effect being more pronounced by pyraclostrobin.
