Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Injurious Insects and the Use of Insecticides: A New Descriptive Manual on Noxious Insects, With Methods for Their Repression Scarcely twenty years ago the best farmers paid little attention to insect depredations. Such losses were regarded as of no significance, or as a part of the ordinary risks of farming. They were looked upon as occasional but inevitable evils which it was nobody's business to try to prevent. In the early Seventies when Dr. Riley and a few other scientists were laboring to overcome popular prejudice against the use of Paris green, in fighting the Colorado Potato-beetle, agriculturists, as a class, were indifferent and inactive until brought to their senses by serious losses or by the complete destruction of crops. But we have learned better since those times. To-day it is only the thriftless farmer who insists on growing crops to be eaten up by insects.

This book was released on 2013-03-14 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: Professor Albert S. Perry passed away suddenly on February 18, 1992, leaving behind his grieving family, friends and colleagues. It was his aspiration to produce a comprehensive work on insecticides to summarize his lifelong dedication to the field of entomology and public health. On the day before his operation, he expressed his desire with the following words: . "1 am coming out of this surgery and will recuperate from it as soon as possible for the sake of my boy (then aged three) and the book". He also told me that he would like to add a chapter on IPM (Integrated Pest Management) and suggested that we write it together. The sad reality is that none of this took place the way he had planned and these became his last words. On my own, I found it difficult to proceed with the writing of the IPM chapter, since several chapters are required to cover· this subject and, in fact, several books. are already devoted to IPM. There was even an IPM article written in a journal (Awake 1983) for a general audience to which he commented that he would like to use it someday because it was well written for laymen, thus providing the readers a wide selection of journals and books to choose from.

Book Synopsis Insecticide Microbiology by : R. Lal
Download or read book Insecticide Microbiology written by R. Lal and published by Springer. This book was released on 2011-12-08 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of all the food produced in the world one third is lost to insect pests, weeds and diseases, and the total world population is estimated as growing from 4000 million in 1975 to about 6000 million by the year 2000. To satisfy these needs, the world's farmers must meet the extra requirement every year. The easiest way in which farmers can increase the amount of food they produce is to prevent the loss due to pests. The biological control measures which were once thought to be the safest methods of pest control have, as we now know, not proved successful on a commercial scale. In such a dismal situation the only solution is to use pesticides to save the losses from pests and to increase the crop yield. Apart from agriculture, pesticides have also contributed much to human com fort by controlling the vectors of typhoid, malaria, sleeping sickness, filariasis, dengue hemorrhage fever, plague etc. On the other hand, the indiscriminate use of insecticides and their harmful effects on nontarget organisms has attracted much attention from people in all walks of life, for example, scientists, administrators, the press and the public. The harmful effects of insecticides on higher organisms such as birds, fish and mammals are easy to observe and have received much attention. However, the interactions of insecticides with microorganisms such as bacteria, fungi, algae and protozoa have gone unnoticed until recently.
