All this creates a despondency that affects our lives in the work place and at home. It is in times like these that the scientific community and weeds fraternity in particular, should stand together and come up with innovative ideas to rise above the circumstances and contribute to the creation of a better world for all. What better platform can one wish for than the 4th IWSC in Durban in June 2004? The Local Organizing Committee is busy setting the stage. The pre- and post-Congress tours are in an advanced stage of planning. The Program Committee has set up a wide selection of topics to which you can contribute. An entertaining spouse program is in the offing and we have also catered for those who want to use the opportunity to learn and enjoy more of Southern Africa.

Current Situation Frequently Asked Questions Publications Other Information ... Home Page Weeds Current Situation According to the Rand McNally Atlas of the United States, Mississippi has 47,234 square miles of land and water surface area within its boundaries. Since a square mile is 640 acres, there are 30,229,760 acres in our state that will grow weeds if unattended. Approximately 12.6 million acres, or 40 percent of the state, are used for crop production and 60 percent, or 18.5 million acres, are used for timber production. Weeds grow on every acre used for crop and timber production. Weeds also grow in those areas not used for crop and timber production. Weeds can be found just about everywhere and all times of the year. Weeds in lawns: Weeds occur in home lawns during winter, spring, summer, and fall. There are many different types of weeds that invade lawns. A thick, dense turfgrass canopy is the best defense one can have against weed invasions. Diseases, insects, cold damage, inadequate sunlight, acid soils, poor drainage, fertilizer burn, poor fertility, poorly adapted turf type, poor mowing practices, or other factors can cause the turfgrass canopy to thin, creating areas for weeds to emerge. Follow recommended turf maintenance practices to provide the first level of defense against weed invasions. Herbicides can then be used to control those weeds that emerge in those areas.

Glyphosate Resistance Dominates Weed Science Meetings MIKE HOLMBERG / Successful Farming 6dec02 Based on the number of papers dealing with glyphosate-resistant weeds at this week's North Central Weed Science Society meeting in St. Louis, you could draw one of two conclusions. Either the weed scientists have all the major weed control issues sorted out already, or else glyphosate-resistant weeds are a genuine threat. Depending on who you talk with, you could make an argument either way. A symposium on glyphosate-resistant weeds attracted an overflow crowd on Thursday morning to hear updates on glyphosate-resistant marestail in the DelMarVa area, west Tennessee, Kentucky, southern Indiana and southern Ohio. Marestail (horseweed) is a big concern because it is a prolific seed producer and the seeds are easily blown around by the wind. Although marestail is the first row-crop weed to develop glyphosate-resistance in the US, there are several other species being watched. Weed scientists in Iowa and Missouri have been testing waterhemp from a handful of fields that seems to have more tolerance to glyphosate. In addition, there have been more complaints about marginal control of velvetleaf, ivyleaf morningglory and lambsquarters control with glyphosate. The big question is whether it makes more sense to try to avoid resistance problems or simply to deal with them if they show up. Although both claim to be proactive, as you might expect, Monsanto and Syngenta are taking slightly different approaches to that question.

Fundamentals of Weed Science (Second edition) Robert Zimdahl Academic Press 1999 Hardback 555 pages ISBN 0127810625 The book is a fully updated introduction to the field of weed science, written at a level appropriate to introduce the subject matter and stimulate interest in learning more. It presents an in-depth coverage of weed ecology, weed-crop rotation and allelopathy, as well as presenting new developments in weed management systems, written with a focus on ecological aspects rather than from the point of view of chemical herbicides. It will be of value to both researchers who require a survey of the basics of weed science and to those professionals who require a primer in weed science in order to evaluate impact assessments for particular weed management strategies.

Basic and applied studies in weed ecology, weed-crop competition, herbicide efficacy, environmental fate, crop tolerance, and cultural agronomics are conducted to assess the impact of weed interference, determine critical weed density thresholds, discover ways to optimize herbicide performance and crop safety, and integrate cultural and chemical control methods. Experimental and non-labeled herbicides are evaluated to assess their fit and potential usefulness in semi-arid dry land cropping systems.

Valentine The World of Weeds and Environmental News Updates ...Now Offering Science Project Books Find Osama In our home gardens , weeds demand a great portion of our time and effort to cultivate a beautiful garden. In the economy of agriculture, controlling weeds is a serious, mission-critical, operation. We are surrounded by weeds. Ever since humans began planting and cultivating plants, weeds have been a problem. A weed is any plant in the wrong place. Weeds take valuable space, water, sunlight and nutrients that may otherwise be accessible to important crops. This degrades the quality of agricultural products, increases costs, and may result in poor nutrition for the intended consumer. Consequently, many agricultural solutions include efficient, but potentially toxic chemicals. Here you may discover that some of the weeds you find in your garden may be harmful to the environment or noxious to your regional ecology.

They contribute to substantial levels of crop loss in smallholder systems, particularly in the tropics and sub-tropics, where a combination of resource constraints at household level, difficult-to-control species, and often a poor understanding of crop/weed interactions complicate the development of sustainable control systems. In many farming systems of the developing world weed control is the most labour demanding pre-harvest operation, for example accounting for up to 60% of labour used for maize production in sub-Saharan Africa. Very often women and children shoulder much of this burden. Removing wild rice (

C.H.I.P.S. HOME PAGE SUBJECT LIST TITLE LIST MANUAL ORDER FORM ... QUESTIONS COMMENTS Basic Weed Science Reference from C.H.I.P.S. Applied Weed Science Second edition by Merrill A. Ross and Carole A. Lembi This introduction to the principles of weed science shows how to analyze real-life weed control problems and to develop integrated, practical approaches to solving them. Comprehensive in coverage and unique in presentation, Applied Weed Science blends basic information on plant systems, soil systems, control methods, and management systems, and discusses various plants and herbicides by groups to provide an integrated framework from which to extend information to many different situations. Stresses the grouping of information (rather than the listing of information) to provide a strong framework from which to extend information to many different situations, e.g.: Groups plants according to characteristics and life cycles. Groups weed control strategies for individual crops by crop life cycles and management systems (e.g., annual crops, herbaceous perennial crops, woody plants, etc.). Groups herbicides by mode of action and chemistry and presents the groups against a framework of how they are used and how plants respond to them.
