Chemical Control of Broomrape Infesting Faba bean Feilds in Northern State, Sudan

Abstract

 Northern State Located within latitude 16° and 22° N ., and longitude 20° and 32° E . , to de

The experiment was conducted during two consecutive winter seasons of the years2021 /22 and 2022 /23 at nursery of General Administration of Plant Protection, Dongola and nursery of Faculty of Agricultural Sciences at Selaim , University of Dongola,  Northern State, Sudan   respectively termine  the effect of glyphosate and Pursuit herbicides on emergence and growth of broomrape, estimation of faba bean seed yield loss percentage due to broomrape Parasite infection and evaluate and compare the effect of the two mentioned herbicides on the broomrape, besides determination the best treatment of the two herbicides which achieve highest faba bean yield (ton/ha). Broomrape Parasite full season competition to faba bean crop significantly reduced seed yield by 77.04 and 78.33%  in both winter seasons, the first and the second, respectively. Glyphosate (52.5 kg a .i/ha) applied at 4, 6 and 8 weeks after sowing, respectively and broomrape seeds free full season treatment significantly increased faba bean seed yield (ton /ha) by 177.91% and 140.77% in both winter seasons, the first and the second, respectively. All treatments of the two herbicides applied pre and post – emergence and broomrape seeds free  full season treatment significantly reduced number of broomrape plants/m² in the first winter season. All treatments of the two herbicides applied pre and post – emergence and broomrape Seeds free full season treatment significantly reduced shoot dry weight (g) of broomrape plant in the both winter seasons. Faba bean yield (ton /ha) in the first winter season is more than which obtained in the second winter season.
