Evaluation of autumn or spring applications of ethoprop for the management of Meloidogyne chitwoodi on potato
AbstractA field experiment was conducted to evaluate whether autumn or spring application of ethoprop is effective for the control of Meloidogyne chitwoodi on potato. Application of ethoprop (19 or 14 l/ha) together with metam sodium (37 l/ha) during autumn or spring significantly reduced nematode infestation of potatoes compared with the untreated control. Per cent nematode infestation was reduced to 0.2 % and 2.7% by autumn or spring application, respectively. Application of ethoprop and metam sodium together in autumn or spring reduced the nematode infestation and increased the clean yield and marketable yield.
