Qualidade fisiológica de sementes de algodoeiro submetidas a tratamentos químico e biológico

Abstract: Uma alternativa aos tratamentos químicos de sementes é o uso de bioprotetores, por meio da microbiolização e, dentre esses, Trichoderma spp. têm sido considerados eficientes no controle de fungos e bactérias. Este trabalho foi conduzido com o objetivo de avaliar a eficiência dos tratamentos de sementes de algodoeiro com os fungicidas carboxin+thiram, carbendazin+thiram e flutolanil, comparando-os com Trichoderma harzianum, na germinação, no vigor das sementes e na promoção de crescimento das plântulas. Foram u… Show more

“…Positive results of isolates of Trichoderma species were reported by Dubey et al (2011) and Dubey and Singh (2013) in other crops. These results match those obtained by Faria et al (2003), who carried out a study on cotton, whose seeds were treated with biological agent Trichoderma harzianum and showed performance similar to that of the seeds treated with chemical fungicides carboxin + thiram and carbendazim + thiram. Grain yield in 2012 was higher (40%) (1,604 kg•ha -1 ) than in 2013 (1,142 kg•ha -1 ), due to climatic conditions as mentioned above.…”

“…Migliorini et al (2012) verified that canola seeds treated with Trichoderma harzianum and fungicides were more vigorous than the control (untreated), having a higher germination speed. Cotton seeds treated with T. harzianum, Carboxin + Thiram and Carbendazin + Thiram had a statistically higher germination percentage when compared with the control (Faria et al, 2003), unlike the results obtained in the present study, which probably occurred because seeds used in that study had high physiological potential.…”

“…Um eficiente sistema de controle de patógenos em sementes, causadores de tombamento e morte de plântulas e das podridões radiculares é a introdução de bioprotetores por meio da microbiolização, definida como a aplicação de micro-organismos vivos ou de seus metabólitos na proteção de sementes, sendo este método já utilizado na promoção de germinação e crescimento e, no controle de diferentes patógenos (Faria et al, 2003). Muitos micro-organismos têm sido estudados, bem como a técnica utilizada para incorporação dos esporos dos fungos junto às sementes (Harman, 2000).…”
