Evaluation of autumn or spring applications of ethoprop for the management of Meloidogyne chitwoodi on potato

Resumo

A 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.
