Abstract A simplified mathematical model of nodding thistle (Carduus nutans) reproduction, growth and competition with grass has been constructed. Using the model, an attempt has been made to study the long-term economic implications of controlling nodding thistle infestations on grazed pasture in New Zealand using the herbicide MCPB. The indications from the model are that, in general, the highest long-term benefits are to be attained if herbicide is applied in October, whenever the thistle… Expand
Seasonal life‐history models for the integrated management of the invasive weed nodding thistle Carduus nutans in Australia
A seasonally structured, individual-based model, specifically designed to compare and rank detailed management strategies for a noxious pasture weed, predicts that the root-crown weevil Trichosirocalus mortadelo will more effectively suppress weed populations than either of the two flowerhead-feeding insect agents Urophora solstitialis and Rhinocyllus conicus.

Strategies for the control of Avena sterilis in winter wheat production systems in central Spain
The strategy that combines the use of a fallow year with herbicide application in the wheat year resulted in optimum wild oat control and moderate profitability under all conditions, however, the net returns obtained were substantially lower than in the continuous wheat plus herbicide strategy.

A review of the ecology and control of thistles in Australia.
Summary: Studies on the ecology and control of thistles in Australia, particularly those related to pasture improvement, are reviewed, and the results used to interpret increases and changes inExpand
Pastoral weeds in New Zealand: Status and potential solutions
Prioritisation of these weed species will be necessary if New Zealand's pastoral agricultural industries are to make long‐term, economically optimal decisions about their management, and will require robust models of their current and potential distributions, their rates of population increase and spread, a full understanding of the merits and pitfalls of alternative control options, and robust model of their impacts on pastoral productivity.

Factors Affecting Spotted Knapweed (Centaurea stoebe) Seedling Survival Rates
Spotted knapweed seedling survival was lower when plant competition was present but varied substantially among the sites, and can vary among habitats on the basis of plant competition and precipitation. Expand
Biological Control of Musk Thistle: A Reassessment
Musk thistle and nodding thistle are names commonly used to describe Old World thistles in the Carduus nutans species group (family Asteraceae). These include Carduus macrocephalus DesfontainesExpand
Improving the efficiency of herbicide application to pasture weeds by weed-wiping and spot-spraying : a thesis presented in partial fulfillment of the requirements for the degree of Doctor of Philososphy in Plant Science at Massey University, Palmerston North, New Zealand
Methods to reduce herbicide application through improved targeting of weeds, thereby also reducing damage to pastures are investigated, finding that over-application of clopyralid and triclopyr/picloram provided residual activity up to 18 and 30 weeks, thereby potentially preventing re-establishment of white clover.

It is found that Kentucky is facing a large threat from exotic invasive plants as they are reported throughout most counties and Cumulative curves of occupied counties over time fit a “J” shape expansion curve, which indicates the potential for further future invasion. Expand
Germination of seed from five broadleaf weeds after burial for up to 28 years in two soils
Very few of the seeds were viable after being buried for 28 years in a clay soil, while in a sandy soil seeds of the three thistle species remained viable when buried at 200 mm depth. Expand
Mathematical models in weed management
The future of weed modelling would seem to lie in trying to marry various aspects to create models more firmly anchored on physiological principles and biological variation. Expand


A mathematical modelling approach to the study of the economics of controlling Rumex obtusifolius in grassland
While the model cannot be used to derive practical recommendations it can and does provide some useful insights into herbicide control of docks, and confident economic predictions of the value of controlling docks in grassland await further experimental work on the population dynamics of docks.

Demography of Two Natural Populations of Musk Thistle (Carduus Nutans)
Variation in the demography of musk thistle can best be explained by phenotypic plasticity rather than genetic causes. Expand
