Synergized Mycoherbicides for Resistance Management

1997
Despite the large number of excellent herbicides available, there are many cases where there are needs to control single weed species. These needs include: a) Weeds that have evolved resistance to a still favored herbicide. Typically, only a single weed (initially) evolves resistance under monoherbicide monoculture, and the herbicide still ...

Mycoherbicide formulation and the potential for bracken control

Pesticide Science, 1993
AbstractThe imperfect fungusAscochtya pteridis, causal agent of curl‐tip disease, is considered as the potential active ingredient of a mycoherbicide for the control of bracken (Pteridium aquilinum(L.) Kühn) Results of experimental attempts to improve pathogenicity by the addition to the spore inoculum of one or more adjuvants are reviewed.

Sodium Alginate for Production and Formulation of Mycoherbicides

Weed Science, 1983
Sodium alginate was used to prepare pelletized formulations for each of five fungi.

Formulation of mycoherbicides using a pasta-like process

Biological Control, 1991
Abstract A new pasta-like (“Pesta”) process has been developed whereby fungal propagules are encapsulated (entrapped) in a wheat gluten matrix. A dough prepared from wheat flour, filler, fungus, and water was rolled into a thin sheet, air-dried, and ground into granules. The mycoherbicide agents Alternaria cassiae, A. crassa, Colletotrichum truncatum,

Engineering hypervirulence in a mycoherbicidal fungus for efficient weed control

Nature Biotechnology, 2002
Agents proposed for biocontrol of major weeds in arable row-crop agriculture have not met expectations because an evolutionary balance has developed between microorganism and weed, even when the mycoherbicide is used inundatively at very high levels (>10(4)spores ...

Formulation of mycoherbicidal strains ofFusarium oxysporum

Weed Science, 1998
Biomass abundant in chlamydospores obtained by liquid fermentation of mycoherbicidal strains ofFusarium oxysporumwas incorporated into alginate prills with various food substrates and granular formulations such as corn flour : starch, wheat flour : kaolin, rice : wheat flour, and rice : wheat gluten formulations.

Adjuvants, Formulations, and Spraying Systems for Improvement of Mycoherbicides

Weed Technology, 1996
Herbicides are used in the production of almost 100% of agronomic crops in the United States and in most horticultural row crops. By volume, herbicides represent nearly two-thirds of all pesticides used in crop production. However, public pressure is mounting to force industry to develop safer, more environmentally responsible approaches for ...

Herbicides as Synergists for Mycoherbicides, and Vice Versa

Weed Science, 2010
Except for a small number of cases in which biocontrol agents were introduced from the site of origin of a weed (classical biocontrol), there have been few cases where a pathogen was virulent enough to perform cost effectively in the field as a mycoherbicide.

A Vegetable Oil-Based Invert Emulsion for Mycoherbicide Delivery

Biological Control, 1996
Abstract A vegetable oil was used as the major constituent to develop an invert emulsion for use with mycoherbicidal agents. The oil phase (CPWA) contained soybean oil, a paraffinic spray oil, paraffin wax, and the emulsifying agents Arlacel 780 and Arlacel 989.

The Mycoherbicide Approach with Plant Pathogens

1991
It is nearly a decade since the first of fungal herbicides, DeVine and COLLEGO, were introduced for commercial use, establishing mycoherbicides as a practical means of weed management. In 1982 Templeton (156) reviewed the status of weed control with plant pathogens, providing a comprehensive list of mycoherbicide candidates (Figure 2.1).
