Manual 5:PESTICIDES AND HEALTH,SAFETY & THE ENVIRONMENT Alternatives to pesticidesAbout thissectionIntroductionThis section will help us to: find out about alternatives to pesticides prepare us to argue for alternatives in our workplaces especially as partof collective bargaining agreementsIn agriculture, especially where the same crop is grown repeatedly on thesame l<strong>and</strong> (monocultures), the indiscriminate use of pesticides has led toproblems of pesticide dependence, pesticide resistance, <strong>and</strong> pestresurgence. The overuse of chemicals has meant that pests have evolvedresistance to certain pesticides, i.e. they are no longer killed or controlledby certain pesticides. Calendar application of pesticides has also harmednon-target, beneficial predators, parasites <strong>and</strong> pathogens which helpnaturally control pests. As a result there has often been a resurgence of thesurviving pest which the pesticide was unable to control, leading to newcrop losses. Indeed, there is growing evidence to show that far from solvingpest problems, pesticides may aggravate existing ones <strong>and</strong> even createnew pests.Regular pesticide use can lead to dependence where more <strong>and</strong> morepesticide or newer <strong>and</strong> newer active ingredients have to be used tomaintain pest control levels. Farmers, who were dependent upon yieldsmade possible by pesticides, need to apply more <strong>and</strong> more powerfulpesticides to sustain yields. These problems have prompted the search foralternatives to chemical pesticides, which can be broadly categorised as: Integrated Production <strong>and</strong> Pest Management Organic AgricultureNote: The pesticide/biotechnology industry claims that use ofbiotechnology, based on genetically modified organisms (GMOs), couldprovide alternatives to chemical pesticides. This claim however needscareful discussion <strong>and</strong> examination as there are many areas of uncertainty<strong>and</strong> many powerful counter-arguments to this industry claim. For thisreason, the subject of genetically modified organism biotechnology <strong>and</strong>pesticides is not dealt with here as an alternative.263 <strong>Health</strong>, <strong>Safety</strong> <strong>and</strong> <strong>Environment</strong>A Series of Trade Union EducationManuals for Agricultural Workers
