Aspergillus leaf spot of field bindweed (Convolvulus arvensis L.) caused by Aspergillus niger in China

Leaf spot was found on field bindweed (Convolvulus arvensis L.) in Shihezi City, Xinjiang Province, China, during the summer of 2015. Pathogens were isolated from the infected leaves of field bindweed and identified as Aspergillus niger based on morphological and molecular analyses (internal transcribed spacer rDNA and β-tubulin gene). A pathogenicity test confirmed that Aspergillus niger cause...

Towards the management of field bindweed (Convolvulus arvensis) and hedge bindweed (Calystegia sepium) with fungal pathogens and cover crops

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 o...

Effect of combined and split applications of phomopsis convolvulus and dicamba on control of field bindweed (convolvulus arvensis L.)

EVALUATION OF BIODIVERSITY OF FIELD BINDWEED POPULATION IN VARAMIN

Many polymorphisms exist in field bindweed (Convolvulus arvensis L.) populations. These differences that appear especially in their flower and leaf cause to different biotypes of this weed that are different in view of dry weight, rate- and flowering period. This research was accomplished during 2005 to 2006 at Weed Research Department, Iranian Plant Protection Research Institute for identifica...

Tropane alkaloids and toxicity of Convolvulus arvensis.

Horses in a few, localized northern Colorado pastures exhibited weight loss and colic. At post mortem, intestinal fibrosis and vascular sclerosis of the small intestine was identified. The pastures where the affected horses grazed were overrun by field bindweed (Convolvulus arvensis). Bindweed from the pasture was found to contain the tropane alkaloids tropine, pseudotropine, and tropinone and ...

Eect of the pre-emergence bioherbicide Phomopsis convolvulus on seedling and established plant growth of Convolvulus arvensis

The e€ects of the fungal pathogen Phomopsis convolvulus Ormeno on seedling and established plant performance of Convolvulus arvensis L. were compared under both controlled and ®eld conditions. Under a controlled environment, a granular barley formulation of the fungal inoculum that had been applied on to the soil surface of pots containing pre-germinated C. arvensis seeds resulted in above-grou...
