The future of microbial bioherbicides
Pest Management Science, 2023The use of microbial bioherbicides in cultivated crops reached an impasse several decades ago. The three of us thought that the time had come to convene a conference to consider the reasons why so little progress has been made in development and commercialization of microbial bioherbicides and to discuss solutions to the impediments. This issue of Pest

Outlooks on Pest Management, 2021
New solutions to weed management are needed now more than ever. Ag retailers, university extension specialists and farmers consider the evolution of herbicide-resistant weeds "one of the most significant developments in agriculture today." Indeed, weed resistance is not just a US problem, but a global one.

Use of plant viruses as bioherbicides: the first virus‐based bioherbicide and future opportunities
Pest Management Science, 2023AbstractUntil recently, only a few plant viruses had been studied for use as biological control agents for weeds, but none had been developed into a registered bioherbicide. This position changed in 2014, when the US Environmental Protection Agency granted an unrestricted Section 3 registration for tobacco mild green mosaic virus (TMGMV) strain U2 as a

BIOHERBICIDES: RESEARCH AND RISKS
Toxin Reviews, 2007Many microbes have bioherbicidal activity, and several phytopathogenic fungi and bacteria have been patented as weed-control agents. The phytotoxic components of most agents have not been elucidated, but some phytotoxins and other secondary compounds produced by such microbes may be toxic to mammalian systems. Furthermore, few rigorous assessments have

ACS Sustainable Chemistry & Engineering, 2017
This study presents the properties of a new group of ionic liquids (ILs) based on various cations and pelargonic acid, a natural nonselective herbicide. The obtained bio-ILs were obtained with high yield (>92%) using a metathesis reaction or neutralization of quaternary ammonium hydroxides and characterized in terms of physicochemical properties. Tests

Weed control is one of the greatest concerns in agriculture and land management. Chemical control methods are widespread, but there are many invasive species for which these are not economically feasible. In addition, there are social, economic and political drivers that work towards reducing the overall use of pesticides.

Advances in bioherbicide formulation
Weed Biology and Management, 2003Formulation of a bioherbicide ideally should result in a product that has low cost, long shelf‐life, ease of application and efficacy. Formulation persists as a constraint to commercial development of many potential bioherbicides often because dew dependence in fungi limits their efficacy under dry‐land conditions.

Constraints in the Development of Bioherbicides
Weed Technology, 1995Bioherbicides are biological control agents applied in similar ways to chemical herbicides to control weeds. The active ingredient in a bioherbicide is a living microorganism and it is applied in inundative doses of propagules. Most commonly the microorganism used is a fungus and its propagules are spores or fragments of mycelium; in this case the ...

Synthesis of the Bioherbicidal Fungus Metabolite Macrocidin A
Organic Letters, 2016The second total synthesis of macrocidin A afforded the bioherbicidal fungal metabolite in 16 steps starting from doubly protected l-tyrosine. The 3-octanoyl side chain with the α-methyl group and an ω-bromo epoxide already in place was attached to the tetramic acid via a Yoshii-Yoda acylation, and the macrocycle was eventually closed in 55% yield by a

Genetic Improvement of Bioherbicides
2002Plant pathogenic fungi and bacteria potentially provide an ecologically sound means of suppressing weeds in agricultural and natural environments. Traditionally, the challenge of biological control has been to find naturally occurring plant pathogens capable of controlling a weed population (Charudattan 1991; Auld and Morin 1995).
