摘要: Field experiments were conducted with maize as a test crop during 2006-2009 to study the effect of atrazine on its persistence and residue in soil produce influenced by quantity application seasons. The treatments imposed control, 0.5 1.0 kg ai ha -1 replicated thrice randomized block design. For analysis, samples collected at periodical intervals from 0 day harvest also sampled post harvest. was determined using GC equipped FID detector. Persistence showed gradual degradation advancement growth. recommended dose left no whereas double recorded 0.056 ppm soil. Pooled data that dissipation biphasic nature faster higher than lower dose. Degradation followed first order kinetics mean half life 21.54 days. season years application.
