Effects of some organic phosphorus and endosulfan seed dressings on wheat

Abstract

The effects on wheat of three organic phosphorus insecticides and endosulfan applied as seed dressings were tested in a field trial at rates that had shown promise for the control of larvae of Desiantha caudata, Pasc. (family Curculionidae). Endosulfan and phosalone seed dressings did not reduce grain yield. Diazinon decreased plant emergence and grain yield. Plant emergence and yield decreased with increased rates of application of methomyl and with addition of the fungicide, Demosan (R) to the methomyl seed dressings.
