| Resumo: | The ever increasing global population needs substantial resources for food
production. However, food production as well as its protection is imperative.
The situation gets particularly critical in developing countries where the net
food production rate is slowing down relative to the population rise. The
world food situation is aggravated by the fact that, in spite of all the available
means of plant protection, a major fraction of the yearly output of food com-
modities gets destroyed by various pests including bacteria, fungi, viruses,
insects, rodents and nematodes. The production of mycotoxins by fungi has
added new dimensions to the gravity of the problem. Losses at times are
severe enough to lead to famine in large areas of the world that are densely
populated and dependent on agriculture.
The use of synthetic pesticides has undoubtedly contributed to a green
revolution in different countries through increased crop protection. How-
ever, recent years witnessed considerable pressure on consumers and farm-
ers to reduce or even eliminate the deployment of synthetic pesticides in
agriculture owing to environmental risks emerging from their indiscriminate
use. Thus, there has been renewed interest in botanical pesticides as the alter-
native and eco-chemical option in pest management. It is also imperative for
sustainable agriculture to reduce the incidence of pests and crop diseases to
a degree that does not seriously damage the farmer’s products and also to
develop cost-effective strategies with minimal ecological side effects.
The use of locally available plants in the control of pests is an age-old
technology in many parts of the world. Some plants, namely Derris, Nicotiana
and Ryania, were used to combat agricultural pests during the prehistoric
era. Used widely until the 1940s, such botanical pesticides have been par-
tially replaced by synthetic pesticides that are easier to procure and longer
lasting. |
