Book Description Daya Publishing House, New Delhi, India, 2001. Hardcover. Condition: New. Dust Jacket Condition: New. First Edition. Pyrethrum is regarded as a section of the genus Chrysanthemum, family Compositae. Besides their ornamental importance, pyrethrum flowers have been widely used as a source material for preparation of insecticides. Being non-poisonous to man pyrethrum is particularly adapted for controlling household insects, however its use for preparing horticultural dusts and sprays, and livestock sprays is no less popular. With a brief introduction to the cultivation and harvesting of different varieties of pyrethrum, this book is a valuable source of all the necessary scientific information related to evaluation of pyrethrum (by chemical as well as biological methods) and manufacturing of various pyrethrum products- powder, extracts and sprays, etc. Also discussed are the effects of storage, light and heat on pyrethrum products, and the methods of detecting adulteration of pyrethrum. There are 100 tables of scientific data, numerous illustration, an exhaustive index and an extensive list of about 1000 reference for further information. Printed Pages: 396 with plates, figures, tables, bibliographies and indexes. Size: 15 x 23 Cm. Seller Inventory # 037302
