Abbau von Herbiziden und Fungiziden durch Mikroorganismen des Bodens

open access: yesCHIMIA, 1973
Herbicides and fungicides are chemicals which increase and ameliorate production in agriculture and save manpower. Herbicides are used to control weeds without destruction of useful plants. Fungicides protect plants against the attack of phytopathogenic

Uncovering renewable energy policy impact channels on land values, the local farm structure, and farmland heterogeneity

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Germany's Renewable Energy Sources Act (REA), enacted in 2000 and subsequently amended, subsidized national renewable energy production with fixed feed‐in tariffs for renewable energy sources (RE) from wind, solar, and biogas. Empirical studies suggest that the policy was creating windfall effects for landowners and attribute farmland use ...

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

open access: yesWeed 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.

Per‐ and Polyfluoroalkyl Substances (PFAS) Exposure Profiles and Their Predictors in a Study of US Volunteer Firefighters

open access: yesAmerican Journal of Industrial Medicine, EarlyView.
ABSTRACT Introduction Firefighters may experience occupational exposure to per‐ and polyfluoroalkyl substances (PFAS). Volunteer firefighters make up 65% of the US fire service, but their serum PFAS profiles have not been well characterized. This study aims to (1) describe PFAS serum profiles among US volunteer firefighters from 9 states enrolled in ...

Natural compounds with herbicidal activity

open access: yesItalian Journal of Agronomy, 2007
Research about phytotoxic activity of natural compounds could lead both to find new herbicidal active ingredients and to plan environmental friendly weed control strategies. Particularly, living organisms could be a source of compounds that are impossible, for their complexity, to synthesize artificially. More over, they could have alternative sites of

The natural herbicide rhein targets photosystem I

open access: yesScientific 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.

Herbicides with natural and synthetic biostimulants in spring wheat [PDF]

open access: yesCiência Rural, 2018
ABSTRACT: Although the knowledge on agricultural using of biostimulants increases, there is still little information on their interactions with other chemicals i.e. herbicides. The aim of the study was to assess the influence of popular herbicides (MCPA + dicamba, dicamba + triasulfuron, florasulam+2,4-D) used with and without biostimulants based on ...

Efficacy of natural fatty acid based herbicides on mixed weed stands

open access: yesJulius-Kühn-Archiv, 2018
In the search for alternatives to synthetic herbicides we assessed the efficacy of 2 non-selective, natural products. The active substances were fatty acids: one herbicide containing pelargonic acid (C9) and the other containing caprylic (C8) and capric ...
