The bindweeds Calystegia sepium and Convolvulus arvensis are difficult to control chemically. Calystegia sepium is often a problem in maize or in vineyards, while C. arvensis is an important weed of cereals. The biological control of these weeds with insects or fungal pathogens has been investigated since 1970. More than 600 fungi collected in countries throughout Europe have been isolated in our laboratories. The isolates with the highest and most stable pathogenicity against bindweed belong…

The Potential of Stagonospora sp. as a Mycoherbicide for Field Bindweed

Severe disease developed on plants inoculated with 1 107 spores/ml in oil emulsion, even in the absence of exposure to 100% RH, even if the plant had not been exposed to the fungus before.

Stagonospora convolvuli LA39 for Biocontrol of Field Bindweed Infesting Cotoneaster in a Cemetery

S. con volvuli may be useful as a mycoberbicide for the control of field bindweed in amenity areas but it would need to be applied every year.

Release and Establishment of Aceria malherbae (Acari: Eriophyidae) for Control of Field Bindweed in Texas

The gall mite is now being released on field bindweed in South Dakota, New Jersey, and Oklahoma, which represents the first successful establishment of an introduced arthropod for biological control of a crop weed in the United States.

Development of Colletotrichum gloeosporioides f.sp. clidemiae and Septoria passiflorae into two mycoherbicides with extended viability.

Viability was optimally maintained in both fungi when they were stored at -18°C and when the spore-kaolin mixtures were rehydrated in sterile distilled water (SDW), and no significant differences in pathogenicity were found in spores as a kaolin formulation after 4 months of storage.

Botrytis cinerea kills groundsel (Senecio vulgaris) infected by rust (Puccinia lagenophorae).

Mortality was most rapid it plants were inoculated with B. cinerea as rust colonies first erupted through the host's epidermis, and a reduction in the concentration of conidial inoculum increased time to death, and concentrations below 015 × 103 conidia ml-1 failed to cause 100 % mortality within the 32 d of the experiment.

Glyphosate Suppression of an Elicited Defense Response : Increased Susceptibility of Cassia obtusifolia to a Mycoherbicide.

The results suggest that a specific inhibition of a weed's elicited defense response can be a safe way to enhance virulence and improve the efficacy of the mycoherbicide.

The Mycoherbicide Approach with Plant Pathogens

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, and the field has indeed grown significantly.

Field Trials of Sclerotinia sclerotiorum to Control Canada Thistle (Cirsium arvense)

An isolate of Sclerotinia sclerotiorum (Lib.) de Bary collected from a Canada thistle [Cirsium arvense (L.) Scop. # CIRAR] plant in Montana proved pathogenic on Canada thistle in field trials. In

Epidemic Spread of a Rust imported for Biological Control

This work believes that this is the first example in the recent history of quarantine controls, of the deliberate introduction and successful release in a new country of a plant pathogen for weed control.

Field Bindweed (Convolvulus arvensis) Control with Various Herbicide Combinations

Under drought conditions in Kansas in 1988, picloram did not control field bindweed as well as in Colorado, Wyoming, or Montana where rainfall was normal, and Glyphosate plus 2,4-D or glyphosate plus dicamba premixes, or 2, 4-D added todicamba were less effective for long-term control of field Bindweed.
