The Neem Tree
The most comprehensive and best illustrated treatment of the fascinating tropical neem tree (Azadirachta indica) and its unique substances. The extracts from the neem tree have an enormously broad range of applications. The main substance azadirachtin, a tetranortriterpenoid, influences the hormone system of insects, exerting thereby a pesticidal effect. Feeding activity, reproduction and flying ability of insects are also affected. It is biologically degradable and can be easily extracted from the seeds of the tree. Other important uses of neem tree products are: - antifertility and population control - cure of human diseases - manure and nitrification inhibitors - feeds for domestic animals - soap production With its exhaustive treatment of the neem tree and closely related plants, this book provides us with an impressive example of the varied uses of renewable resources.
Phytochemical Biopesticides
In recent years, the development of biological pest control strategies has focused on the chemical profiles of insect-plant interactions. Plants exhibit an extensive range of defensive strategies, which include insect avoidance, deterrence and antibiosis. The need to overcome these vegetative defence responses has driven the evolution of an array o
Neem: Today and in the New Millennium
The chemicals from plant sources, generally termed as phytochemicals, play an important role in acceptance or rejection of the plant by the pests as they could be distasteful or toxic on one hand or on the other hand specialist herbivores have the capability to feed on many such chemicals, as they are able to process these natural products in a manner that is beneficial to them. In the wake of increasing environmental degradation due to burgeoning synthetic chemicals, there has been a process going on to rediscover the usefulness of plants and herbs and a continued effort for more than 2 decades has been to study the green products for cures for several ailments and pest management. In fact,...
Neem
This comprehensive review on neem is an excellent collation of observations and research efforts by botanists, taxonomists and medical practitioners and will be of interest to everyone with an interest involved in medicinal and aromatic plant research.
Neem
Neem is a fascinating tree. On the one hand, it seems to be one of the most promising of all plants and may eventually benefit every person on the planet. Probably no other yields as many strange and varied products or has as many exploitable by-products. Indeed, as foreseen by some scientists, this plant may usher in a new era in pest control, provide millions with inexpensive medicines, cut down the rate of human population growth, and perhaps even reduce erosion, deforestation, and the excessive temperature of an overheated globe.On the other hand, that all remains only a vague promise. Although the enthusiasm may be justified, it is largely founded on empirical or anecdotal evidence. Our purpose here is to marshal the various facts about this little-known species, to help illuminate its future promise, and to speed realization of its potential.This report has been produced by the National Research Council particularly for nonspecialists such as government ministers, research directors, university students, private voluntary organizations, and entrepreneurs. It is intended as an economic development document, not a scientific monograph.
Neem in Sustainable Agriculture
Neem is a versatile tree of Indian origin. Since ancient times, its various plant parts have been used to control domestic insects, stored grain pests, crop pests and for human and livestock medicine. Recently, these properties have been attributed to hundreds of chemicals present in this Golden tree. Being a storehouse of chemicals, with multiple uses and adaptability to diverse habitats and climatic conditions, the developed countries have been shown keen interest in this tree. Besides, the present day pesticides and nitrogen fertilizers pose several problems viz., environmental pollution and related health hazards in human and livestock insects. While neem chemicals have shown potential as pesticides and as nitrification inhibitors and do not pose these problems, moreover, neemcake is used as manure. This book will be most useful to neem scientists working in agriculture and forestry and to environmental conscious farmers of developed countries and to the educated farmers of Third World countries intending to practice Sustainable Agriculture.
