Summary: | Some fungicides were tested in control of Rhizoctonia solani in bean ( Phaseolus vulgaris ) planted in soil inoculated with this fungus. The evaluations were made at 10, 20 and 30 days after sowing, observing germination and damping-off. The results showed that the fungicides thiram (280g. a.i./ 100kg seeds) have no increased plant stand in Phaseolus vulgaris , in relation to the non treated control. Seed treatments with PCNB (450g a.i./ 100kg seeds), iprodione + thiram (200g a.i/l00kg seeds) and iprodione + thirarn (240g a.i./100kg seeds), increased plant stand in percentages varying from 65 to 73%, respectively in relation to non treated control, but the best treatment was with iprodione + thiram (320g a.i./l00kg seeds), presenting an increase around 83%.
Foram testados alguns fungicidas no controle de Rhizoctonia solani em feijoeiro ( Phaseolus vulgaris L.), semeado em vasos com solo previamente inoculado por este fungo. As avaliações foram feitas aos 10, 20 e 30 dias após o plantio, levando-se em consideração ausência de germinação e plântulas tombadas. Os resultados mostraram que o fungicida thiram (280g i.a./100kg de sementes), não aumentou o stand de plantas em relação à testemunha. Sementes tratadas com PCNB (450g i.a./l00kg de sementes), com iprodione + thiram (200g i.a./l00kg de sementes) e com iprodione + thiram (240g i.a./l00kg de sementes) aumentaram o stand em percentagens que variaram de 65 a 73%, em relação à testemunha, mas o melhor resultado foi obtido com iprodione + thiram na concentração de 320g i.a./ 100kg de sementes, que promoveu aumento do stand em cerca de 83%. |
