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

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).

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 ...

Glucosinolate-containing plant tissues as bioherbicides
Journal of Agricultural and Food Chemistry, 1995Enzymatic hydrolysis of glucosinolates, a class of compounds found in Brassica species, results in a number of products with potential to inhibit seed germination. To investigate the impact of both volatile and water soluble allelochemicals, germination bioassays were conducted with Lactuca sativa seeds in the presence of defatted seed meal of Brassica

ALELOKEMIKALIJE POKROVNIH KULTURA – POTENCIJALNI BIOHERBICID
2022Sjetva pokrovnih kultura kao jedna od mjera unutar integriranog sustava proizvodnje dobiva sve veći značaj zbog brojnih pozitivnih učinka na očuvanje okoliša, bioraznolikosti i povećanje plodnosti tla. Sjetva pokrovnih usjeva jedan je od načina potiskivanja korova bilo kompeticijom i, ovisno o vrsti, alelopatskim djelovanjem.

Enhancing the Efficacy of Bioherbicides
2003Plant pathogenic pseudomonads are inhibited by certain amino acids due to feedback inhibition or repression of key biosynthetic enzymes in amino acid biosynthesis pathways. As it turns out, plants are similarly inhibited by certain amino acids. These inhibitions can play a large role in plant pathology.

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

Bioherbicidal activity from washed spores of Myrothecium verrucaria
World Journal of Microbiology and Biotechnology, 2012The fungal plant pathogen, Myrothecium verrucaria, is highly virulent to several important weed species and has potential utility as a bioherbicide. However the production of macrocyclic trichothecene mycotoxins by this fungus presents significant safety concerns. It was discovered that trichothecenes are removed from M.

Use of Essential Oils as Bioherbicides
Journal of Essential Oil Bearing Plants, 2008A study was conducted to assess the allelopathic effects of essential oils from Eucalypt, Lawson Cypress, Rosemary and White cedar with the objective of exploring the possibility of their utilization for future weed management. The effects of these four essential oils on the germination of three weed species were examined.
