| Abstract | ||||
| In pot trails, during two successive seasons (2001/2002) and (200212003) foliar application of glyphosate (10 - 25 ppm), fosamine ammonium (50 - 200 ppm) and their mixture (5 ppm glyphosate + 25 ppm fosamine ammonium - 12.5 ppm glyphosate + 100 ppm fosamine ammonium) was evaluated for controlling Orobanche crenata in peas (Pisum sativum L.). Both phosphorus herbicides and their mixture substantially controlled O. crenata parasitism in peas, by reducing the number, fresh and dry weights of O. crenata tubercles as compared with infected control. Applying glyphosate at (25 ppm) and its mixture with fusainine (12.5 ppm glyphosate + 100 ppm fosamine ammonium) showed potential effect for eliminating O .. crenata infestation in peas as compared with other their concentrations. Fosamine ammonium showed some phytotoxicity on the host particularly at higher concentrations either as compared with glyphosate or mixture. Both herbicides and their mixture significantly increased the root and shoot biomass of pea plant as well as pea yield, as compared with infected control. It has been suggested that glyph os ate has potential effect for controlling Orobanche crenata parasitism in pea plant, rather than fosamine ammonium or their mixture. | ||||
