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).

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

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.

Bioherbicides: Their Role in Tomorrow’s Agriculture
1992The current status of bioherbicide development is briefly reviewed and factors constraining development are considered. The problems of strain selection, inoculum production, bioherbicide formulation, pesticide interactions and genetic manipulation and variability are addressed and indications given of the progress towards resolving some of the ...

Formulation of Colletotrichum coccodes as a bioherbicide
1993Colletotrichum coccodes (Wallr.) Hughes, a foliar pathogen of velvetleaf, is being developed as a bioherbicide. Formulation of living organisms for use as pest control products presents unique problems. This research has achieved the development of an adequate formulation of the pathogen by using kaolin clay or talcum powder (1:2.79 wt/wt) as the ...
