Description Reducing poverty and ensuring future food and nutritional security are major concerns of the
Asian-Pacific region (the region) which is characterized by rapid population growth, food
crises and climate change. Efforts to increase crop productivity and reduce existing crop
yield gaps, by identifying constraints such as weeds and alleviating them, are essential to
meet the targeted food and nutritional security goals in the region. The Asian-Pacific Weed
Science Society (APWSS)‘s prime objective of promoting weed science in the region, by
pooling and exchanging information has been done primarily through its biennial
conferences and publications. In this review, an effort is made to assess the extent of
achievement of APWSS prime objective by analyzing the APWSS publications. The
research work reported and published on weeds and their weed management, methods
adoption by farmers, shifts in weeds and farmer’s needs, is synthesized and the future weed
management research needs of the region are suggested. The discovery of 2, 4-D has led to
intensified herbicides based weed management research and publications in both developed
and developing countries of the region. Herbicide use became major weed management
tool in developed countries and is increasing gradually in developing nations. Currently,
herbicides became an indispensable input of agriculture in most countries in the region.
However, herbicide resistant weeds, the shifts in weed population and emergence of
invasive weeds like weedy rice and climate change became major weed management
challenges. Around $250 million investment with ten years or more time for new herbicide
molecule development has slowed down new herbicides introduction. Genetically modified
Herbicide Tolerant Crops (HTC) was introduced in certain countries as a component of
Integrated Weed Management (IWM). Herbicide tolerant weeds emergence due to gene flow
and non-adoption of stewardship guidelines, health and environmental concerns and lack of
trained personnel are limiting HTC introduction and adoption. Thus, IWM, better
understanding weed ecology, biology and best weed management practices became major
areas recent research and publications of weed management in the region. Genetic
engineering, automation and artificial intelligence, better understanding of weed biology and
ecology as influenced by climate change may provide innovative options to generate
creative sustainable weed management approaches to efficiently, economically and
ecologically manage weeds in the region. The decision making tools and location specific
efficient weed management technologies popularizing extension methodologies are
essential. APWSS will continue to play key role in strengthening Weed Science and
sustainable weed management in the Asian-Pacific region.
