Book excerpt: Excerpt from Experiments With Fungicides Upon Potatoes in 1900: How to Fight Potato Enemies The copper salt is dissolved in a wooden tub or earthen jar and the lime slaked in a separate vessel. Dissolve the copper sulphate in about two gallons of hot water in a wooden or earthen vessel by stirring, or by suspending it from the top of the vessel in a cloth bag, immersed in the water; pour the solu tion into the tank or barrel used for spraying and fill one-third to one-half full of water. Slake the lime in a separate vessel by the addition of a small quantity of water, and when slaked add two or three gallons of water and stir freely. Pour the milk of lime thus made into the copper sulphate solution, pass ing it through a brass wire strainer Of about 30 meshes to the inch (no. Or through a cheese-cloth backed by common window screen. Stir constantly while adding the lime. Add water to make the amount up to 50 gallons.

This book was released on 2017-10-27 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Reports of Experiments With Various Insecticide Substances, Chiefly Upon Insects Affecting Garden Crops, Made Under the Direction of the Entomologist Possibly those who have experimented have, through fear of injuring the plants, hesitated to use water cold enough or have used it too sparingly and in the cooler part of the day. In making the discovery I was too late to avail myself of caution about the safety of the plant, and was compelled to solace myself with the idea that if the cold had injured and killed them I was not in a worse predicament than before using the cold water, for if I had killed the plants I had only anticipated a few days the certain result of the pests. Perhaps the vermin are of a tougher habit in a warmer climate, and I would not hesitate to reduce the temperature of the water another degree or two and be sure of the top degree of the day to apply it. Several persons have told me that they used it last season with success, and one person that he had not been troubled this season, not yet having discovered any worms; but until recently but few persons in our vicinity grew more than a hundred plants. This season I have noticed not a few acres planted with cabbages. Please have your tests made properly and in the right time, and I think you will succeed. It may seem too simple to be of much benefit, and scarcely worth the trial, and single efforts may fail for want of a little care. Let them act as if there should be no such thing as failure, and they will succeed. Drench more frequently.

Download or read book Resistance 91 Achievements and Developments in Combating Pesticide Resistance written by I. Denholm and published by Springer Science & Business Media. This book was released on 1992-07-31 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of pesticide resistance in arthropod pests, plant pathogens and weeds can be viewed and studied from two contrasting perspectives. At a fundamental level, resistance provides an almost ideal example of adaptation to withstand severe environmental stress. Population geneticists, biochemists and, most recently, molecular biologists have cast considerable light on the nature of this adaptation in diverse taxonomic groups, and on factors determining its selection and spread within and between populations. Unlike most evolutionary phenomena, however, resistance is also of immediate practical and economic significance. Not only has the number of resistant species continued to increase inexorably, but there has been an alarming increase in the severity and extent of some resistance problems. Cases of organisms resisting virtually all available pesticides are by no means uncommon, and pose a formidable challenge in view of present difficulties in discovering and developing novel chemicals. Although most occurrences of resistance were initially monofactorial, resistance now frequently involves a suite of coexisting mechanisms that protect organisms against the same or different pesticide groups, and may even predispose them to resist new, as yet unused chemicals.

Download or read book Pesticide Resistance written by National Research Council and published by National Academies Press. This book was released on 1986-02-01 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a symposium sponsored by the Board on Agriculture, this comprehensive book explores the problem of pesticide resistance; suggests new approaches to monitor, control, or prevent resistance; and identifies the changes in public policy necessary to protect crops and human health from the ravages of pests. The volume synthesizes the most recent information from a wide range of disciplines, including entomology, genetics, plant pathology, biochemistry, economics, and public policy. It also suggests research avenues that would indicate how to counter future problems. A glossary provides the reader with additional guidance.
