An investigation was conducted at the Indian Agricultural Research Institute, New Delhi, during the rainy (kharif) season of 1995 and 1996 to determine the persistence of pendimethalin in soil in soybean [Glycine maw (L.) Merr.1 wheat (Tritcum aestivum L. emend. Fiori Paol.) sequence following its application to. soybean. In sandy loam soil, the half life of pendimethalin at 1.0 and 1.50 kg a.i.1 ha was 24 and 26 days respectively. The inital dissipation of pendimethalin was rapid and nearly 35 36% of the original value was lost in 15 days and thereafter it was gradual. Nearly 27 28% residues remained in the soil afterf 45 days of its application and ascertained safety to succeeding wheat crop, as the pendimethalin residues reached non detectable level after the harvest of soybean.References
