ABSTRACT

The study aimed at investigating the combined application of prometryn (herbicide) plus benzoic acid at different concentrations for controlling weeds and on seed yield in lentil (Lens culinaris L. cv. Giza 370). The experiment was carried out in the new reclaimed land of Egypt (Experimental Station of NRC, El-Nobaria District, El Behera Governorate) during two successive seasons (2007/08 and 2008/09). The application of prometryn at 600 g a.i.·ha^-1 in tank mixture with benzoic acid at the concentration of 720 g·ha^-1 resulted in as effective-weed control and yield as applying the herbicide alone at the recommended dose (1200 g a.i.·ha^-1), without apparent toxicity on lentil plants. Using the herbicide at 900 g a.i.·ha^-1 in combination with benzoic acid at either concentrations (240, 480 and 720 g) was also good, however it was toxic to lentil especially at the higher concentration of benzoic acid. None of the herbicide treatments resulted in yields higher than the hand-weeded treatment performed twice. The primary benefit from the application of benzoic acid in this study was to reduce the herbicidal doses and then environmental pollution.

Key words: benzoic acid, combined effect, lentil, natural products, prometryn herbicide, weed control.
