dc.description.abstractAims Compatibility of seed-applied pesticides and rhizobial inoculants is an important consideration for farmers when sowing legumes. Some of the seed-applied pesticides may influence rhizobial growth and nodulation, but there is currently little available information on the potential inhibitory effects. Therefore, common seed fungicidal and insecticidal treatments were assessed to determine adverse impacts on rhizobial inoculants both in vitro, on treated seed, and in the field. Methods and Results Initially, the in vitro toxicity of the seed-applied fungicides Thiram 600, P-Pickel T (PPT), their active ingredients (thiram and thiabendazole) and the insecticide Gaucho to rhizobia was measured with filter discs containing varying concentrations of the pesticides. Pea and chickpea seed was then coated with the same pesticides and inoculated with rhizobia in different inoculant substrates to determine bacterial survival and nodulation. Finally, a field trial using the fungicide PPT and commercial inoculants was conducted. Some seed fungicide treatments were found to be inhibitory to rhizobia and reduce nodulation under monoxenic conditions and in the field. Significance and Impact of the Study These data provide more detailed information on the compatibility of specific rhizobial inoculants with common seed-applied pesticides. This research will provide information on the compatibility of rhizobia and seed-applied pesticides, and assist farmers to select sowing practices which reduce the risk of crop nodulation failures.
