Description:Excerpt from Bordeaux Mixture Methods of warfare against fruit pests - fungi, bacterial diseases and insects - have developed in a wonderful manner during the last few years. The devastations of parasites have forced upon fruit growers the conviction that strong effort in the direction of efficient control is the only salvation for the fruit business. The idea of making applications to fruit trees to check or prevent the ravages of insects and diseases is by no means new. Remedies for fruit tree troubles were recommended by early writers and it seems probable that their use may be as old as fruit culture. Early remedies were mainly of the nature of repellents, substances which, on account of bad odors, caustic, or other disagreeable properties, were thought capable of driving away insects or warding off disease. In a few cases, perhaps, applications were made before invasion and with the definite purpose of preventing attack, but more frequently applications followed the discovery that serious injury had been inflicted, and were made in an endeavor to check further injury by driving away the invaders. These applications were made, generally, with very imperfect knowledge of the organisms responsible for the injury and without tangible basis for the belief that the nostrums used were in any degree effective against the particular organisms causing the injury. It follows, that, while there were frequent reports of benefit, the major portion of efforts expended in the application of supposed curative substances failed to give relief, or in any way diminish the losses. The treatments here referred to were those of the early days before orcharding had developed as a distinct business. Fruit plantations were, in the main, small, mostly home farm orchards. Applications were intermittent, desultory, without much system and never on an extended scale.We have made it easy for you to find a PDF Ebooks without any digging.
