Sesquiterpene and diterpene glycosides from Xanthium spinosum

Phytochemistry, 1996
Abstract Two new sesquiterpene lactone glycosides and three new kaurene glycosides closely related to carboxyatractyloside and atractyloside, together with the 3′, 4′-didesulphated-carboxyatractyloside and 3′, 4′-didesulphated-atractyloside, were isolated from the aerial parts of Xanthium spinosum . Their structures were established by spectroscopic

Possible control of Xanthium spinosum by a fungus

Agriculture, Ecosystems & Environment, 1988
Abstract Xanthium spinosum L. is among the world's worst weeds and is particularly important in Australia. Although susceptible to 2,4-D it often occurs near crops where the herbicide cannot be used. The fungus, Colletotrichum orbiculare (Berk. et Mont.) v.

Anthracnose of Xanthium Spinosum - Quantitative Disease Assessment and Analysis.

Australasian Plant Pathology, 1988
A sensitive disease assessment and analysis technique was developed for anthracnose of the weed Xanthium spinosum caused by Colletotrichum orbiculare. Time to plant death was used to discriminate between treatments. The disease rating scale reflected disease progression patterns rather than static symptoms. The mean daily rating in all treatments up to

Field applications of Colletotrichum orbiculare to control Xanthium spinosum

Agriculture, Ecosystems & Environment, 1990
The fungal pathogens Colletotrichum orbiculare is being assessed as the basis for a mycoherbicide for biological control of Xanthium spinosum, Bathurst burr or spiny cockleburr. Following preliminary small plot field applications in summer 1987/88, applications of aqueous spore suspensions of 106 or 107 spores ml−1 were made at four sites in summer ...

Sclerotinia Minor - a Pathogen of Bathurst Burr (Xanthium Spinosum).

Australasian Plant Pathology, 1993
A stem rot, similar to that caused by Sclerotinia minor on sunflower (Helianthus annuus), was observed on the weed, Bathurst Burr (Xanthium spinosum), in a sunflower field trial at Numurkah, in north-central Victoria. It was confirmed that the fungus causing the stem rot on the Bathurst Burr was S. minor.

Emergence and flowering in Xanthium spinosum

Agriculture, Ecosystems & Environment, 1993
Abstract Xanthium spinosum , Bathurst burr or spiny clotburr is an introduced widespread annual weed in eastern Australia and several other countries. Experiments and field observations were made to contribute to understanding the species' success. Seed dormancy varied between sites and was not affected by partial fruit coat removal. Seeds in fruits

Phytophagous Insect Faunas of Spiny Clotbur, Xanthium spinosum, and Cocklebur, Xanthium strumarium, in Southern California

Environmental Entomology, 1983
Phytophagous insects representing six orders, 14 families, and 18 identified and 3 unidentified species are reported as comprising the insect fauna of spiny c1otbur, Xanthium spinosum L. (Compositae), in southern California. Similarly, insects representing six orders, 29 families, and 60 species are reported as associates of cocklebur, X. strumarium L.

The properties of the oil of Xanthium spinosum*

Journal of the American Pharmaceutical Association (Scientific ed.), 1949
Some chemical and physical properties of the oil obtained from Xanthium spinosum are reported. Preliminary studies on toxicity and on blood pressure response indicate that the oil is pharmacodynamically inert.

CONTACT ALLERGY TO COCKLEBUR (XANTHIUM SPINOSUM)

Archives of Dermatology and Syphilology, 1939
During the last three years I have observed a man aged 68 years who had typical dermatitis venenata in April, two years before I saw him. It started on the face, hands, arms and legs, spreading to a lesser degree over the entire body, gradually diminishing in the fall and winter.
