Always consult label prior to use. most popular classifications of pesticides which are widely used isclassification based on the mode of entry, pesticide function and the pest organism they kill, the chemical composition of the pesticide. A. CLASSIFICATION OF PESTICIDES WITIJ EXAMPLES . 1.3 This document “Guidelines on Food Classification for the Pesticide Residues in Food Regulation” (the Guidelines) is intended to facilitate the trade in identifying the appropriate pesticide residue limits that are relevant to the food commodities concerned. Two distinct pesticides and apples were prepared in different concentrations. Toxicity class refers to a classification system for pesticides that has been created by a national or international government-related or -sponsored organization. The next few groups are active on oomycetes (groups 4, P7, 40, 49, 22, 27, 28 and 43). Leave a buffer zone 50 to 100 feet in width (or larger if needed) if sensitive plants are downwind.

The host specificity is the chief advantages of using biological pesticides. The word “pesticide” is an umbrella term for all insecticides, fungicides, herbicides, rodenticides, garden chemicals, wood preservatives, and household disinfectants that may be used to kill some pests. calcium arsenate. This disrupts feeding and other behaviors in target insects. 2. Functional chemical group . "Pesticide" is a general term used for a chemical designed to kill target pests such as insects (insecticide), mites (miticide), weeds (herbicide) and organisms which cause plant diseases such as bacteria (bactericide) and fungi (fungicide). HAZARD CLASSIFICATION. 3. There are three main classes of pesticides to watch out for are insecticides, herbicides, and fungicides. Insecticides target the insects, herbicides the weeds, and fungicides are designed to kill any type of fungus or bacteria at the microscopic level that can directly affect the plants. botanical insecticides. Pesticide Management Division, NIPHM, Hyderabad-30 2 1. Alternating the class of insecticide used for controlling insects can delay or even prevent insects becoming resistant to those chemicals.

For each group in the classification, reference is made to the potential for acquiring residues, the portions of the crops or animals which are normally consumed and the portions of the commodities to which the MRLs apply (and which are analysed). Insecticides are used in agriculture, medicine, industry and by consumers. It addresses the acute toxicity of agents such as soil fumigants , fungicides , herbicides , insecticides , miticides , molluscicides , nematicides , … While each chemical has unique properties, a family of herbicides has similar chemical structures with many similar characteristics. Pesticides PESTICIDES – CLASSIFICATION BY USE Insecticides Herbicides Fungicides Rodenticides Fumigants Insect repellents Wood preservatives Chemicals designed to kill, reduce or repel pests Insects Weeds Moulds Rats, mice, moles There is a large variety of pesticides designed to kill specific pests – those most widely used are listed below.

This chart contains some Restricted Use Pesticides. GROUP Ib. Group A: "Human Carcinogen" "This group is used only when there is sufficient evidence from epidemiologic studies to support a cusal association between exposure to the agents and cancer." Insecticides are substances used to kill insects. Insecticide Spraying by the Numbers. Reliance on a single chemical or a group of chemicals in the same insecticide class can lead to development of resistance at a faster rate. Insecticides are substances used to kill insects. malathion, parathion, diazinon, chlorpyrifos, azinphosmethyl, acephate, phorate, and phosmet) as well as compounds that work as fumigants (e.g., DDVP) and as systemics (e.g. Karmex, Direx, others. 50. of the pesticide formulation as a whole, in accordance with the criteria given in 6.1.3 to 6.1.5 (inclusive).

This was done against the advice of CARC, the California EPA, and other agencies that agreed the classification should not be downgraded. Plant or animal controlled 2. Resistance is the result of repeated use of one or more similar pesticides over a number of years. There is known cross-resistance between Groups 1A and 1B. In general, the first few groups are active on Botrytis and similar fungi (Groups 1, 2, 12, 9, 17 and 7). Two exceptions in the FRAC/EPA classification scheme are the “multi-site activity” fungicide class and the “unknown” class of fungicides with unknown modes of action. Herbicides are chemicals with complex chemical structures. 2 The final classification of any pesticide product is intended to be by formulation. What is a pesticide? copper arsenate.

Pharmacological action 6. They include ovicides and larvicides used against insect eggs and larvae, respectively. Classification, illustrated its use by listing examples of classification of some pesticidal active ingredients and their formulations. The etiquette will therefore end up looking something like this. The pesticides tetrachlorvinphos and parathion were classified as possibly carcinogenic to humans (Group 2B) based on convincing evidence that these agents cause cancer in laboratory animals. The WHO Recommended Classification of Pesticides by Hazard was approved by the 28th World Health Assembly in 1975 and has since gained wide acceptance.

The next few groups are active on oomycetes (groups 4, P7, 40, 49, 22, 27, 28 and 43). Classification: All pest control products are classified for intended use and by toxicity into one of four pesticide classes (domestic, commercial, manufacturing or restricted). All fungicides within a chemical group share a common mode of action and resistance mechanism, even though their chemical structures may be different. Pesticide is a general word that describes numerous groups of insecticides, fungicides, herbicides, garden chemicals, household disinfectants and rodenticides that are operated to both destroy and protect from pests (He, 1994, Eldridge, 2008, El Nemr et al., 2012, El Nemr et al., 2012, El Nemr et al., 2012).These pesticides vary in their chemical and physical properties from one class to another. Most environmental toxins are an unwanted by-product of another process (for example, outflow from a manufacturing plant or emissions from an automobile engine). In general, a pesticide is a chemical or a biological agent such as a virus, bacterium, antimicrobial, or disinfectant that deters, incapacitates, kills, pests. 1.2.2 Classification according to Target Pest Common name Accepted (or proposed) common name for an individual active ingredient expected to appear on the product label as definition of the product.

Classification of Pesticides The U.S Environmental Protection Agency (EPA) defines a pesticide as “any substance or mixture of substances intended for preventing, destroying, repelling, or mitigating any pest”. pesticide resistance should be an active part of pest manager’s decision-making portfolios. It takes into consideration the toxicity of the technical active substance and also describes methods for the classification of formulations. 40 CFR 152.160(a). carbofuran, carbosulfan, dimethoate, monocrotophos). Pesticide Label: The label is a legal document between the EPA, manufacturer, and the consumer. The LC50 is calculated over 24 h. In all cell types, fungicides were the most toxic (mean LC50 12 ppm). They were followed by the herbicide Roundup (LC50 63 ppm), twice as toxic as Starane, and more than 10 times as toxic as the 3 insecticides, which represent the less toxic group (mean LC50 720 ppm). The group includes many general purpose insecticides with a wide range of mammalian toxicity (e.g. Wettable Powders (WP)- consist of finely divided particles with other substances that enable the powder to be mixed with water to form a stable suspension e.g. 2 . 2.3 Classification of pesticides The word "pesticide" is an umbrella term for all insecticides, herbicides, fungicides, rodenticides, wood preservatives, garden chemicals and household disinfectants that may www.intechopen.com.
