Natural products as herbicides for tree establishment [PDF]

Forestry, 2005
Summary The selectivity and effi cacy of the foliar-acting natural-product herbicides bilanaphos and citronella oil were tested in comparison with glufosinate-ammonium. When applied to tree-base foliage of 10 species of broadleaved and coniferous trees in May or June they caused contact damage to the sprayed area only. Overall application of bilanaphos

Manuka Oil, A Natural Herbicide with Preemergence Activity [PDF]

Weed Science, 2011
Natural herbicides approved in organic agriculture are primarily nonselective burn-down essential oils applied POST. Multiple applications are often required due to their low efficacy. To address this problem, the in vivo herbicidal activity of manuka oil, the essential oil distilled from manuka tree (Leptospermum scopariumJ.R. and G.

The natural herbicide rhein targets photosystem I

Scientific Reports
The natural anthraquinone rhein has been identified as a novel herbicide with a potentially new mode of action using a generative AI system for functional molecules discovery. Its herbicidal activity was light-dependent and resulted in rapid burndown symptoms on leaves of treated plants.

Tricolorin A as a Natural Herbicide [PDF]

Molecules, 2013
Tricolorin A acts as pre- and post-emergence plant growth inhibitor. In pre-emergence it displays broad-spectrum weed control, inhibiting germination of both monocotyledonous (Lolium mutliflorum and Triticum vulgare) and dicotyledonous (Physalis ixocarpa and Trifolium alexandrinum) seeds, being the dicotyledonous seeds the most inhibited. Tricolorin A

Synthesis of Cyclotetrapeptides Analogues to Natural Products as Herbicides

Molecules, 2022
The synthesis of cyclotetrapeptides analogues of the natural products tentoxin and versicotide D was achieved in good yield by solid phase peptide synthesis (SPPS) of their linear precursors and solution phase cyclization. All the cyclopeptides and several open precursors were evaluated as herbicides.

Natural Compounds as Next-Generation Herbicides [PDF]

PLANT PHYSIOLOGY, 2014
Herbicides with new modes of action (MOAs) are badly needed due to the rapidly evolving resistance to commercial herbicides, but a new MOA has not been introduced in over 20 years. The greatest pest management challenge for organic agriculture is the lack of effective natural product herbicides.

Assessing Herbicide Efficacy of Pelargonic Acid on Several Weed Species

Agronomy, 2023
Pelargonic acid is the most successful natural herbicide and can contribute to reducing synthetic herbicides, but information on its efficacy is contrasting.

Effect of Different Parameters (Treatment Administration Mode, Concentration and Phenological Weed Stage) on Thymbra capitata L. Essential Oil Herbicidal Activity

Agronomy, 2023
The essential oil (EO) of Thymbra capitata has been demonstrated to possess herbicidal activity and could be used as an alternative to synthetic herbicides with reduced persistence in soil and new mode of action.

Synthesis of Aminophenoxazinones and Evaluation of Their Phytotoxicity in the Search for New Natural Herbicides [PDF]

Agronomy, 2023
Natural products have been postulated as an alternative to the use of synthetic herbicides in pest control. The latter compounds have caused numerous problems and these include the appearance of resistance to such herbicides. Aminophenoxazinones are natural products that have shown multiple biological activities, such as pharmacological or phytotoxic ...
