Abstract

To search the natural and eco-friendly herbicides, different mixtures of sorghum (Sorghum bicolor), sunflower (Helianthus annuus), brassica (Brassica napus) and mulberry (Morus alba) aqueous extracts were investigated against germination and growth of horse purslane (Trianthema portulacastrum). In laboratory bioassays, the mixture (100%) of sorghum + sunflower + brassica + mulberry aqueous extracts completely inhibited the germination and seedling growth of T. portulacastrum. In pot culture, two foliar sprays of sorghum + sunflower + brassica + mulberry water extracts inhibited its growth (leaf area, root and shoot length) and drastically reduced the dry matter production (96%). Thus mixture of foliar spray of sorghum + sunflower + brassica + mulberry aqueous extracts may be used as natural herbicide for T. portulacastrum control.
