Southern Africa has possibly the most beautiful and diverse floral kingdom in the world, but it is also the most polluted and threatened. Agricultural production is under threat from both indigenous and alien weeds and our entire ecosystem is now being seriously threatened by these alien, invasive species. Awareness of these weeds, the regulations involved and possible control measures have become critical factors. Things change in time, more weeds appear and the scope of this edition is extended up into more Central Africa. This then initiated the fourth revised and updated edition, titled Problem Plants and Alien Weeds of Southern Africa.

AMAZING FEATURES
The contents cover more than 800 problem plants of which 433 species are illustrated and their origin, environmental impact and control measures are described. Similar species are mentioned.
More than 900 colour photographs assist with identification, create more awareness and illustrate the problematic nature of plants.
Up-to-date distribution maps show the range in Southern Africa.
The existence of a herbicide registration (in South Africa) is indicated with “H” where applicable, and the latest government regulations (NEMBA categories: 1a, 1b, 2 and 3), as well as biological control, where applicable, are mentioned next to the distribution map.
Introductory chapters cover biodiversity and the threat of alien species; problematic indigenous vegetation including bush encroachment; veld degradation; control and management techniques; biological control; chemical weed control; herbicide resistance, and the threat posed by ornamental garden plants.
ABOUT THE AUTHOR
Clive Bromilow holds a degree in Applied Biology with a major in Ecology. He has been involved in the agricultural chemical industry all over the world for over 40 years and this has led to a lifelong interest in plants and weeds. His first book Problem Plants of South Africa was published in 1995 and was a huge success. This edition and the subsequent three revised editions were very successful and became reference books on the subject throughout Southern Africa and indeed the world.

Plants and alien weeds of South Africa, this title became a guide for anyone interested in knowing how to recognise, understand and control troublesome plants. The title covers more than 500 species of problem plants in detail, with descriptive and interesting text, highlighting the origin and environmental impact of each species as well as methods of control. There are over 700 colour photographs to assist with identification and to illustrate the problematic nature of the plants. Up-to-date distribution maps show the range of each plant, while a series of icons offers an easy overview of the pest status of a plant and how it is covered by government regulations, herbicide registration and biological control. Introductory chapters explain aspects of undesirable vegetation such as bush encroachment and veld degradation, as well as chemical and biological control techniques and the threat posed by ornamental garden plants. An innovative 'identification key' helps even the non-botanist to find and identify a particular species.
