Q&A on Pests and Pesticide Management

FAO - News Article: Q&A on Pests and Pesticide Management

Last updated: 12 May 2021 What are pesticides?  Pesticides are any substance or mixture of substances of chemical or biological ingredients intended for repelling, destroying or controlling any pest, or for regulating plant growth. The term pesticide applies to insecticides, herbicides, fungicides, rodenticides, molluscicides, wood preservatives and various other substances used to control pests. Pesticides also include plant growth regulators, defoliants and desiccants. The use of pesticides in agriculture goes back thousands of years, however, pesticides began to be applied more broadly from the 1940s due to the growth of synthetic chemical pesticides and rapid development of biopesticides in the past decade. Today, there are more than one thousand pesticides available on the market (including chemical, microbial, semi-chemical and botanical pesticides).

Study: Pesticide bans can be a cost-effective intervention for reducing suicide deaths

Study: Pesticide bans can be a cost-effective intervention for reducing suicide deaths National bans on highly hazardous pesticides can be a cost-effective and affordable intervention for reducing suicide deaths in countries with a high burden of suicides attributable to pesticides, according to a new study published in The Lancet Global Health today. The exploratory economic analysis, one of the first to examine the cost-effectiveness of implementing a population-based, suicide prevention intervention in low- and middle-income countries, involved 14 countries spanning low-income to high-income settings. The authors concluded that banning highly hazardous pesticides across those 14 countries could result in a total of approximately 28 000 fewer suicide deaths each year at an annual cost of I$ 0·007(or less than a cent) per capita.
