  • Hazardous Materials List
    Hazardous Materials List Version: 1.12.2016 v 1.4 All agrochemicals, especially pesticides, can be potentially hazardous in some form or other to human and animal health as well as to the environment and therefore should be used only under caution. Fairtrade International recommends the use of other methods like proper choice of crops and varieties, suitable cultivation practices and biological material for pest, before a chemical pesticide is used for pest control. The Hazardous Materials List (HML) is divided in three lists: the Red List, the Orange List and the Yellow List. Red List: The Red List is a ‘prohibited’ list and includes materials that must not be used on Fairtrade products. Orange List: The Orange List is a ‘restricted’ List and includes materials that may be used under conditions specified in this document thus restricting their use. The use of materials in this list will be monitored by Fairtrade International. Operators should be aware that some of these materials are to be phased out by 30 June 2020 or by 30 June 2022 as indicated in the list. The other materials in the list may eventually be prohibited and are encouraged to abandon their use. Yellow List: The Yellow List is a ‘flagged’ list and includes materials which are flagged for being hazardous and should be used under extreme caution. Fairtrade International will be monitoring the classification of these materials by international bodies like PAN, WHO and FAO, and materials may be prohibited in the future. Operators are encouraged to abandon their use. Classification of materials in the HML The Hazardous Materials List includes materials that are identified as Highly Hazardous as defined in the Code of Conduct on Pesticide Management adopted by FAO and WHO in 2013.

The overall objectives of the IPCS are to establish the scientific basis for assessment of the risk to human health and the environment from exposure to chemicals, through international peer review processes, as a prerequisite for the promotion of chemical safety, and to provide technical assistance in strengthening national capacities for the sound management of chemicals. This publication was developed in the IOMC context. The contents do not necessarily reflect the views or stated policies of individual IOMC Participating Organizations. The Inter-Organization Programme for the Sound Management of Chemicals (IOMC) was established in 1995 following recommendations made by the 1992 UN Conference on Environment and Development to strengthen cooperation and increase international coordination in the field of chemical safety. The Participating Organizations are: FAO, ILO, UNDP, UNEP, UNIDO, UNITAR, WHO, World Bank and OECD. The purpose of the IOMC is to promote coordination of the policies and activities pursued by the Participating Organizations, jointly or separately, to achieve the sound management of chemicals in relation to human health and the environment.

  • Managing Pesticide Poisoning Risk and Understanding the Signs and Symptoms Clyde L
    EC2505 Revised June 2018 Managing Pesticide Poisoning Risk and Understanding the Signs and Symptoms Clyde L. Ogg, Extension Educator Jan R. Hygnstrom, Project Manager Cheryl A. Alberts, Project Coordinator Erin C. Bauer, Entomology Lecturer The potential for accidents with pesticides is real. Ac- cidental exposure or overexposure to pesticides can have seri- ous consequences. While most pesticides can be used with relatively little risk when label directions are followed, some are extremely toxic and require special precautions. The Poison Control Centers receive about 90,000 calls each year related to pesticide exposures. Pesticides are re- sponsible for about 3 percent of all accidental exposures to children 5 years and younger and about 4 percent for adults. In addition, pesticides are the cause of about 3 percent of children’s deaths reported to the Poison Control Centers. Routes of Exposure Pesticides can enter the human body three ways: 1) der- mal exposure, by absorption through the skin or eyes; 2) oral exposure, through the mouth; and 3) through inhalation or respiratory exposure, by inhaling into the lungs. Some classify exposure through the eyes as ocular exposure. Dermal exposure results in absorption immediately after Figure 1. Absorption rates of different a pesticide contacts the skin or eyes. Absorption will contin- parts of the body based on the absorption ue as long as the pesticide remains in contact with the skin or of parathion into the forearm over 24 eyes. The rate at which dermal absorption occurs is different hours. for each part of the body (Figure 1). Maiback and Feldman (1974) measured the amount of the pesticide parathion absorbed by different parts of the human body over 24 hours.

    VECTOR CONTROL,PEST MANAGEMENT,RESISTANCE,REPELLENTS Susceptibility of Aedes aegypti, Culex quinquefasciatus Say, and Anopheles quadrimaculatus Say to 19 Pesticides with Different Modes of Action JULIA W. PRIDGEON,1,2 ROBERTO M. PEREIRA,1,3 JAMES J. BECNEL,1 SANDRA A. ALLAN,1 1 1 GARY G. CLARK, AND KENNETH J. LINTHICUM J. Med. Entomol. 45(1): 82Ð87 (2008) ABSTRACT To access the relative potency of pesticides to control adult mosquitoes, 19 pesticides with various modes of action were evaluated against Aedes aegypti, Culex quinquefasciatus Say, and Anopheles quadrimaculatus Say. On the basis of 24-h LD50 values after topical application, the only pesticide that had higher activity than permethrin was Þpronil, with LD50 values lower than per- methrin for 107-, 4,849-, and 2-fold against Ae. aegypti, Cx. quinquefasciatus Say, and An. quadrimacu- latus Say, respectively. Abamectin, imidacloprid, spinosad, diazinon, and carbaryl showed slightly lower activity than permethrin (Ͻ20-fold). However, bifenazate showed very low activity against the Ͼ three mosquito species tested, with LD50 values higher than permthrin for 1000-fold. On the basis of 24-h LD50 values, Cx. quinquefasciatus was the least susceptible species to nine pesticides tested (DNOC, azocyclotin, chlorfenapyr, carbaryl, spinosad, imidaclorid, diazinon, abamectin, and per- methrin), whereas Ae. aegypti was the least susceptible species to six pesticides tested (dicofol, amitraz, propargite, hydramethylnon, cyhexatin, and diafenthiuron), and An. quadrimaculatus was the least susceptible species to four pesticides tested (bifenazate, pyridaben, indoxacarb, and Þpronil). Our results revealed that different species of mosquitoes had different susceptibility to pesticides, showing the need to select the most efÞcacious compounds for the least susceptible mosquito species to achieve successful mosquito control.
