Efeito do tratamento de sementes com fungicidas no controle do tombamento em feijoeiro (phaseolus vulgaris l) causado por rhizoctonia solani kohn

Abstract

Some fungicides were tested in control of Rluzoctonia solam in bean (Pha­seolus vu/garis) planted in soil inoculated wilh this fungos. The evaluations were made at 10, 20 and 30 days after sowing, observing germination and damping-off. The results showed lhat lhe fungicides thiram (280g. a.i/!OOkg seeds) have no increased plant stand in Phaseolus vulgaris, in relatioo to lhe non treated cootrol. Seed treatments with PCNB (450g a.i./lOOkg seeds), iprodione+thiram (200g aJ.IIOOkg seed) and iprodione+thiram (240g a.i.llfXlg seeds), inc,ease<J plant stand in percentages varying from 65 to 73%, res­pectively in relation to non treated control, but lhe hest treatment was with iprodione + thiram (320g a.i/JOOkg seeds), presenting an increase around 83%.
