Resumo
Sodium azide (134.5 kg/ha) was compared to methyl bromide (650 kg/ha) for nematicidal activity in field plots over a 2-year period. Plots treated with methyl bromide generally were free of nematodes throughout the study period. Initially, some decrease in nematode numbers was evident in plots treated with NaN3 but none was evident after 24 weeks. Generally, plant parasitic species of nematodes were more affected by NaN3 than were species of predatory or saprophogous nematodes. Data indicate that NaN3 is not an effective nematicide under field conditions.
