Weed Management Systems§
Edited by Brian M. Sindel
This book presents weed management systems from an Australian
perspective. It discusses the
threat that weeds pose and their impact on the Australian economy.
It examines the tactics and capabilities that allow weeds to be as
successful as they are. All available methods for their control and management are
examined in detail including physical, chemical and biological systems.
Weed management strategies are devised for cropping systems, pastures,
vegetables, orchards, and vineyards, lawns and turf, plantation forests,
rangelands and aquatic systems. It
concludes with a discussion of the challenges being faced and future directions
for weed management.

Japan Herbicide Resistance Working Group and The Asia-Pacific Herbicide
Resistance Working Group
The Japan Herbicide Resistance Working Group (JHRWG)
has been organized and initial discussions about the herbicide resistant weed
problems have taken place. The
group is composed of individual members, universities, research institutes,
agricultural research stations and the private sector.
At present, a mailing list (in Japanese) of 73 individual members has
One of the objectives of the JHRWG mailing list is to gather information
about herbicide-resistant weeds in Japan and Korea. For example, a survey of
areas infested with sulfonylurea herbicide-resistant weeds, in Japan and Korea
was made (Table 1).

Panel Discussion on Wet-Sown Rice in Thailand
A panel discussion on Nawannumtom (Wet-seeded) rice in Thailand was held
on the occasion of celebrations for the 72nd anniversary of Mr.
Prachorn Kanchanomai, which was organized by the Weed Science Society of
Thailand. Mr. Prachorn was one of
the founders of the Weed Science Society of Thailand and had introduced
Nawannumtom to the Thai farmers. The
main objective of this meeting was to discuss the developments in these techniques in the past and the adoption of this rice
growing technology. The speakers
included the representative of Thai farmers, Mr. Pracha Lapanun, the former head
of districts, where the cooperation of nawannumtom development was practiced and
Dr. Prasan Vongsaroj as a weed scientist and Dr. Prakorn Soojare as a moderator.
Thai farmers have gained benefits through introducing this method, since
the rice growing period could be shortened, resulting less production costs and

Weed management and crop establishment in various systems.
Rice cultivar suppression of weeds in different culture systems.
Weed Science Society of Thailand Activity
Professor Adisak Buankiyapan of Kasetsart University gave a lecture on the topic
of Weeds and Human＊s Life at the Kasetsart University Alumi Building on 14
December 2001. There were 150
participants attending this special lecture. On this occasion, the members of
the Weed Science Society of Thailand celebrated the 72nd anniversary
of Mrs. Saowanee Thammasara, a former weed scientist of the Royal Department of
Irrigation and the early retirement of Mr. Charuck Boomsrirat, a former weed
scientist at the Rubber Research Institute, Department of Agriculture. Mrs.
Saowanee Thammasara sacrificed herself for research on aquatic weeds and she has
published many papers concerning aquatic weeds, especially Mimosa
pigra. Mr. Charuck Boonsrirat used to work in weed research in
rubber and oil palm and has attended many of the former Asian-Pacific Weed
Science conferences, including Bangalore,
India, Jarkata, Indonesia, Kuala Lumpur, Malaysia and Manila, Philippines.
He has published many papers on weed management in rubber plantations.
same day, the representative President of the Weed Foundation, Dr. Hiran
Hiranpradit chaired the ceremony of the donation of funds to support printing of
theses for Masters degree level concerned with weed science from three
universities, namely Chiang Mai, Prince of Songkla and Kasetsart University.

Invasion of Mimosa pigra L. in Vietnam
The giant mimosa (Mimosa pigra L.) has
posed a new threat to the wetland environment from the North to the South of
Vietnam. It is a perennial woody
shrub native to tropical America and widely naturalized in tropical regions of
Africa, Southeast Asia and Australia. Five-ridged
stems are branched, 2 to 4 m long with dense growth.
Spines and bristles arise from the stems.
Leaves are about 20 cm long and pinnate compounds.
Petioles and leaves are spiny and hispid.
Dormant reaction of leaves by physical stimulation is not strongly
sensitive. Many globose
inflorescences arise from the end of the stem and from the axil of leaf.
Pale reddish purple stamens are conspicuous in the florets.
Pods are compressed, 5 to 10 cm long, about 2 cm wide and densely hispid.
Seeds display a strong dormancy and their viability is long.
Seeds continue to germinate after 23 years.
However, a small proportion of bare seeds without hispid cover can
germinate soon after being removed from the plants.
Young seedlings are weak and less competitive with other weeds and they
are susceptible to shading. Plants
prefer wet and sunny areas and form large communities along the banks of rivers,
canals and wasteland. This
dangerous weed has invaded many wetland areas.
The typical infestation in the Mekong river delta of Vietnam is at the
National Wetland Park of Tram Chim in Dong Thap province.
This park is located in the latitude 10 0 36 / - 10 0 46 / North and in
the longitude 105 0 28 / - 105 0 36 / East with the total area of 7,616 ha.
Now Mimosa pigra has occupied 490 ha and continues to expand.
In a primary survey, results showed that there are about 130 plant
species, 198 bird species and 55 fish species currently in the park.
Especially, some endangered birds such as Grus antigone sharpii are
still living in the area. The fast infestation of giant mimosa can affect the
weed community there particularly those which are used as natural feed for
birds. Birds also hate the dense
community of Mimosa pigra with spiny branches and they migrate to new
areas. The long-term strategic
research and development program for checking the invasion of Mimosa pigra
in the country is urgently needed.

Biology of Weed Control
critically assesses the impact of the new tools of molecular biology on the
science of weed control as well as the ways in which the science of weed control
has helped and influenced molecular biology. This book describes how weed biologists and ecologists are
beginning to use these tools and discusses past successes and failures as well
as taking a look at the future prospects for weed control.
an extensive review of the molecular aspects of the evolution of herbicide
resistance in weeds and genetically engineered herbicide resistant crops, Molecular Biology of Weed Control discusses their shortcomings as
well as suggesting improvements to future generations of such crops.
Accenuating the utility of molecular biology to contribute to the control
of intransigent weed species both in the developing and developed world, the
book also looks to the future and describes how molecular biology can be used to
diminish the use of chemical herbicides, and enhance crop competitiveness for
light, nutrients and water.
a multi-disciplinary, open-minded approach to the problems, pitfalls and
potential benefits of these new technologies and their applications, Molecular
Biology of Weed Control is essential reading for all environmental students,
researchers and regulators, as well as anyone else with an interest in the
future of weed scientists, agricultural production etc.
