Abstract
Due to deleterious impacts of broomrapes against the host plants, its combating is essential for sustaining crop productivity. Thus, two–year field trail was conducted at El Nubaria experimental farm, National Research Centre, Egypt, on two faba bean genotypes (Misr–3 and Sakha–1) to investigate the importance of butyl–iso–butyl phthalate as an activator for broomrape germination in comparison to glyphosate and unweeded. Findings revealed that glyphosate in 2015/16 and 2016/17 seasons in addition to butyl–iso–butyl phthalate in 2016/17 season caused significant reductions in broomrape biomass and numbers of broomrape–infected faba bean plants plot−1 compared to the unweeded. Plots of Misr–3 genotype treated with butyl–iso–butyl phthalate in both season as well as plots of Misr–3 or Sakha–1 sprayed by glyphosate in the first season achieved the maximum seed yield of faba bean. Since butyl–iso–butyl phthalate exhibits suicidal germination of broomrape seeds, it can be exploited as an effective and helpful tool in integrated management programs of broomrape in faba bean fields. Due to deleterious impacts of broomrapes against the host plants, its combating is essential for sustaining crop productivity. Thus, two–year field trail was conducted on two faba bean genotypes (Misr–3 and Sakha–1) to investigate the importance of butyl–iso–butyl phthalate as an activator for broomrape germination in comparison to glyphosate and unweeded. The trail design was a strip–plot in completely randomized block design in six replications. Genotypes occupied the vertical main plots as well as broomrape control treatments distributed in horizontal ones. Results showed that broomrape biomass and numbers of broomrape–infected faba bean plants plot−1 markedly responded to weed control and genotype and their interaction in both seasons, except numbers of broomrape–infected plants of faba bean genotypes plot−1 in 2016/17 season. Also, findings revealed that glyphosate in 2015/16 and 2016/17 seasons in addition to butyl–iso–butyl phthalate in 2016/17 season caused significant reductions in broomrape biomass and numbers of broomrape–infected faba bean plants plot−1 compared to the unweeded. In plots of Misr–3 or Sakha–1, glyphosate was the potent practice for reducing broomrape biomass and numbers of broomrape–infected faba bean plants plot−1 in 2015/16 and 2016/17 seasons, with no significant differences with butyl–iso–butyl phthalate application in 2016/17 season. There were no noticeable variations between weeded practices and genotypes and their interaction on total dry weight of faba bean plants estimated at 105 DAS, in both seasons, except glyphosate x Misr–3 interaction in the first season only. Plots of Misr–3 genotype treated by butyl–iso–butyl phthalate in both season as well as plots of Misr–3 or Sakha–1 sprayed by glyphosate in the first season achieved the maximum seed yield of faba bean. Since butyl–iso–butyl phthalate causing suicidal germination of broomrapes seeds, it can be exploited as an effective and helpful tool in broomrape management programs in faba bean fields.
