“…In spite of the lower mean values observed for the Trichoderma-based product, there are very interesting descriptions on the action of this mutant fungus, where the mortality of tomato plants in contact with Rhizoctonia solani fell 100% if Trichoderma antagonized the pathogen (Montealegre et al, 2010). Another idea defended by Figueirêdo et al (2010) is that the period when the antagonist is applied to control soil pathogens significantly affects the result and that the application of Trichoderma at sowing may make a difference.…”

RESUMO -Avaliou-se o efeito dos tratamentos químicos e biológicos sobre a emergência, vigor de plântulas de mamona, produção de matéria seca, além do controle de microrganismos associados às sementes das cultivares AL Guarany 2002 e Lyra. Os produtos testados foram carbendazim+thiram, carboxin+thiram e um à base de Trichoderma. A emergência total e de plântulas foram avaliadas aos 27 dias após a semeadura e a produção de matéria seca, com plantas retiradas 45 dias após a semeadura. A cv. AL Guarany 2002 apresentou maior incidência de microrganismos em relação à cv. Lyra. O tratamento químico foi 100% eficiente no controle de fungos e o tratamento biológico não reduziu a incidência de microrganismos nas sementes. O tratamento químico resultou em plantas com maior matéria seca e os melhores resultados foram para carbendazim + thiram e carboxin+ thiram, nas doses de 60 g + 140 g e 50 g + 50 g/100 kg de sementes, respectivamente. O carbendazim + thiram foi o único tratamento que se mostrou estatisticamente superior, quanto ao índice de emergência total, enquanto que o tratamento biológico aumentou os valores de emergência somente na cv. Lyra, evidenciando sua inferioridade. Destacou-se a importância dos fungicidas para o controle de patógenos associados às sementes.Termos para indexação: Ricinus communis, fungicidas, teste de papel filtro, Trichoderma.ABSTRACT -The effect of chemical and biological treatments on castor bean emergence, seedling vigor, dry matter production, and also the control of microorganisms associated with seeds of the AL Guarany 2002 and Lyra cultivars, was evaluated. The products tested were carbendazim + thiram, carboxin + thiram and a product based on Trichoderma. Total seed and seedling emergence were evaluated at 27 days after sowing whereas dry matter production was verified for plants removed 45 days after sowing. The Guarany 2002 AL cultivar had a higher incidence of microorganisms than the Lyra cultivar. The chemical treatment was 100% effective in controlling fungi but the biological treatment did not reduce microorganism incidence on the seeds. Chemical treatment resulted in plants with more dry matter and the best results were for carbendazim + thiram and carboxin + thiram at doses of 60 g + 140 g and 50 g + 50 g/100 kg of seeds, respectively. The carbendazim + thiram mixture was the only treatment which was statistically higher for total emergence whereas the biological treatment increased emergence only for the Lyra cultivar, thus demonstrating its lower efficiency. The importance of fungicides to control pathogens associated with seeds was discussed.

“…After 21 st day of incubation, Radial Growth Inhibition (RGI) was calculated according to Rodriguez et al (2000). Additionally, evaluation according to Bell was included (de Figueirêdo et al, 2010): 1 -Trichoderma sp. grows and covers completely all colonies of phytopathogen surface; 2 -Trichoderma sp.…”

“…Trichoderma spp. works as biocontrol agent in several pathologic systems (Carvalho et al, 2011;Figueirêdo et al, 2010;Vinale et al, 2008). Microbiolization enhances plant growth and development, nutrient availability, agricultural production, and induces disease resistance (Jegathambigai et al, 2010).…”

The objective of this study was the effect of leverage microbiolization forage radish seed with Trichoderma spp. and Bacillus subtilis by physiological conditioning techniques, suspension of biological structures and film coating. The microbiolization suspension of biological structures was carried out with commercial products Rhizoliptus ® and Agrotrich plus ® . Fluid restriction was held in PDA medium + mannitol (-0.7 MPa), when was the first seed radicle protrusion in the other were removed and dried in a laboratory environment for 48 h. The film coating was performed with the addition of the polymer Color Seed ® (300 mL kg -1 ) treatment of the syrup containing Trichoderma spp. or product Rhizoliptus ® . We used a treatment covering the seeds primed with organisms, or their association. The microbiolization with Trichoderma spp. by physiological conditioning controls pathogens infecting the seeds. Trichoderma spp. and Bacillus subtilis promote the growth and development of seedlings of forage radish, and the coating of the seeds primed in the presence of organisms which provides greater shoot growth of seedlings in the field. Técnicas de microbiolização de sementes de nabo forrageiro com Trichoderma spp. e Bacillus subtilis RESUMO O objetivo deste trabalho foi potencializar o efeito da microbiolização de sementes de nabo forrageiro com Trichoderma spp. e Bacillus subtilis pelas técnicas de condicionamento fisiológico, suspensão de estruturas biológicas e peliculização. A microbiolização com suspensão de estruturas biológicas foi realizada com os produtos comerciais Agrotrich plus ® e Rhizoliptus ® . A restrição hídrica foi realizada em meio BDA + Manitol (-0,7 MPa), ao ocorrer protrusão radicular na primeira semente, as demais foram retiradas e secas em ambiente de laboratório por 48 h. A peliculização foi realizada com a adição do polímero Color Seed ® (300 mL kg -1 ) à calda de tratamento contendo Trichoderma spp. ou ao produto Rhizoliptus. Foi utilizado um tratamento recobrindo as sementes condicionadas com os organismos isolados ou em associação. A microbiolização com Trichoderma spp. pelo condicionamento fisiológico controla os patógenos infectantes das sementes. Trichoderma spp. e Bacillus subtilis promovem o crescimento e desenvolvimento de plântulas de nabo forrageiro, sendo o recobrimento das sementes condicionadas na presença dos organismos o que proporciona maior crescimento de parte aérea de plântulas no campo.
