Weeds are the main biological
constraint to crop production throughout the year. Uncontrolled weeds could
cause 100% yield loss. In Australia, the overall cost of weeds to Australian
grain growers was estimated at AU$ 3.3 billion annually. In terms of yield
losses, weeds amounted to 2.7 million tonnes of grains at a national level. In
the USA, weeds cost US$ 33 billion in lost crop production annually. In India,
these costs were estimated to be much higher (US$ 11 billion). These studies
from different economies suggest that weeds cause substantial yield and
economic loss. Biology and Management of Problematic Weed Species details the
biology of key weed species, providing vital information on seed germination
and production, as well as factors affecting weed growth. These species include
Chenopodium album, Chloris truncata and C. virgate, Conyza bonariensis and C.
canadensis, Cyperus rotundus, and many more. This information is crucial for
researchers and growers to develop integrated weed management (IWM) strategies.
Written by leading experts across the globe, this book is an essential read to
plant biologists and ecologists, crop scientists, and students and researchers
interested in weed science.
