Phytotoxicity of Natural Molecules Derived from Cereal Crops as a Means to Increase Yield Productivity

Phytotoxicity including autotoxicity and allelopathy is the immediate or indirect biochemical impact of one organism on germination, growth, survival, reproduction other organisms improvement neighbouring plant species through arrival substances into environment. This biological phenomenon effect might be either growth-enhancing (synergistic) inhibiting (hostile), contingent upon chemical delivered from donor plants target species. Allelopathy has been viewed not just as a nature-accommodating way to control unwanted spices biocidal products, but, additionally, potential explanation for causing in yield. The application agents reduce weed infestation may have negative consequences human health well Plants with activities derived secondary metabolites could an alternative strategy expected function sustainable biocontrol boost global agricultural production food security. Thus, protecting biodiversity, ensuring safety, improving food, nutrient quality, crop production, are urgently needed population consumption increasing. So, objective this study present recent advancements phytotoxicity allelopathic extracts (sorghum, sunflower, rice, corn), agroecosystems.
