A carbamate is an organic compound derived from carbamic acid (NH2COOH). A carbamate group, carbamate ester (e.g., ethyl carbamate), and carbamic acids are functional groups that are inter-related structurally and often are interconverted chemically.

Pesticide formulation & available form of organo -chlorinate , carbamate & carbaryl

  1. 1. Pesticide formulation & available form of organo -chlorinate , carbamate & carbaryl 1 Topic
  2. 2. Pesticide Formulation  A pesticide, Sole Active ingredient and Sole Inert ingredient are almost useless, to make a pesticide both are mixed in specific ratio ,which is called Pesticide Formulation. 2
  3. 3. Types of Pesticide formulation Pesticide formulation Other liquid formulations Liquid formulation Solid Formulation s Dusts Granule Wettable powder Pellets Microencapsulates Emulsifiable Concentrates Dry Flowables Liquid Flowables Soluble Powders Solutions Miscellaneous Liquid Formulations Aerosols and Fumigants 3
  4. 4. Solid formulation  Dusts- Dusts are manufactured by the sorption of an active ingredient onto a finely-ground , solid inert such as talc, clay, or chalk.  Granules - A small particle; especially : one of numerous particles forming that the active ingredient is sorbed onto a larger particle. The inert solid may be clay, sand, or plant materials. 4 Granules Dusts
  5. 5.  Pellets Pellets are very similar to granules, but their manufacture is different. The active ingredient is combined with inert materials to form a thick liquid mixture.  Wettable Powders Wettable powder concentrates are pesticide powders that are added to water to create an pesticide solution. 5 Pellets Wettable powder before mixing Wettable powder after mixing
  6. 6.  Soluble Powders Soluble powders are similar to wettable powders with the on major different; all of the ingredients in the formulation are totally water soluble at the use rate. They are applied as solutions in water. 6Soluble powder before mixing with water Soluble powder after mixing
  7. 7. Liquid Formation  Liquid Flowables The manufacture of liquid flowables mirrors that of wettable powders—with the exception that the powder, dispersing agents, wetting agents, etc., are mixed with water before packaging. 7 Liquid flowable before mixing Liquid flowable after mixing
  8. 8.  Solutions Solutions (water-soluble concentrates) consist of water-soluble active ingredients dissolved in water, for sale to the applicator for further dilution prior to field application.  Emulsifiable Concentrates Emulsifiable concentrate formulations are a blend of active ingredient, organic solvent, and surfactants.. Emulsifiable concentrates are mixed with water and applied as a spray. 8 Emulsifiable concentrate before mixing Emulsifiable concentrate before mixing
  9. 9. Other liquid formulations 9 Aerosols - Aerosols really refer to a delivery system that moves the activeingredient to the target site in the form of a mist of very small particles: solids or liquid drops.  Any volatile, poisonous substance used to kill insects, nematodes, and other animals or plants that damage stored foods or seeds, human dwellings, clothing, and nursery stock. Fumigants
  10. 10. 10 A carbamate is an organic compound derived from carbamic acid (NH2COOH). A carbamate group, carbamate ester (e.g., ethyl carbamate), and carbamic acids are functional groups that are inter related structurally and often are interconverted chemically. Carbamate esters are also called urethanes. Carbamate

  12. 12. Carbaryl  Carbaryl (N-methyl-1-naphthyl carbamate; Sevin) is a carbamate insecticide that is widely used, resulting in exposure during its use as well as via consumption of treated food. It is not metabolized to an active intermediate, the parent compound itself is thought to be the active agent. 12
  13. 13. Chemical Description 13  The chemical name of carbaryl is 1-napthyl methylcarbamate., carbaryl is synthesized through treating methyl isocyanate with 1- napthol. The resulting product is a solid, usually colorless crystal that is odorless and soluble in water .
  14. 14. An organo-chlorinated is an organic compound containing at least one covalently bonded atom of chlorine that has an effect on the chemical behavior of the molecule. 14 Organo-chlorinated Chemical Structure:
