1.Dusts (D)-

  • Dusts are made up of a finely ground mixture of active ingredient combined with clay, talc, or other powdered materials.
  • Dusts are intended for dry use and should never be mixed with water.
  • The percentage of active ingredient in a dust is generally quite low.
  • Dusts are commonly used for interior wall void and perimeter treatments, as well as for crop-dusting.

2.Granules (G)-

  • Granules are hard, dry particles made up of porous materials and active ingredient.
  • The percentage of active ingredient in a granule formulation is higher than that of a dust but lower than that of an EC.
  • Granules are usually more safe to apply than dusts or ECs.
  • Granular formulations are used most often for soil treatments.
  • Granules will not cling to plant foliage, so that they may be directly applied over plants or soil.

3.Aerosols –

  • Aerosols are sold in cans and contain one or more active ingredients under pressure.
  • Aerosols pesticides are sold most often for home and garden use, not for agricultural use.
  • The percentage of active ingredient in aerosols is usually very low.
  • One of the main advantages of aerosols is that they are convenient and easy to use. Many aerosols are used for killing pests on contact, or for time-released control of flying pests.

4.Wettable powders (WP)-

  • Wettable powders are dry and powdery.
  • They appear similar to a dust but contain additional wetting and dispersing agents so that water may be added for maximum effectiveness.
  • Wettable powders are also more highly concentrated than dusts to contain more active ingredient.
  • Wettable powder formulations do not form a true solution when water is added, so frequent agitation of the spray tank is required to keep the formulation in suspension.

5.Emulsifiable concentrates (EC)-

  • Emulsifiable concentrates are liquid formulations where the active ingredient is dissolved in oil and an emulsifier is added so that the formulation may be mixed with water or oil for spraying.
  • ECs are among the most widely used formulations, along with wettable powders.
  • ECs typically contain two to six pounds of active ingredient per gallon.
  • Unlike wettable powders, ECs require very little agitation and are easy to handle.

6.Flowable liquids (F or L)-

  • Flowable liquids are made with active ingredients that can not be dissolved completely in water or oil.
  • so the active ingredient is ground up and suspended in a liquid with other suspending agents.
  • The formulation is then ready to mix with water for application. Flowables are easy to handle, will not clog spray nozzles, and require only moderate agitation.

7.Solutions and water soluble concentrates (S)

  • water soluble concentrates are liquids in their original state and are fully soluble in water and any other solvent.
  • Solutions that are prepared the right way will not leave unsightly residues or clog spray nozzles.

8.Soluble powders (SP)-

  • Soluble powders are dry formulations similar to wettable powders, but the difference is that when added to water a soluble powder will dissolve completely and form a genuine solution (whereas a wettable powder does not).
  • Some agitation may be required to dissolve the soluble powder initially, but once a solution, agitation is not needed.
  • The percentage of active ingredient in a soluble powder is high compared to ECs and WPs.
  • There are not currently many SP formulations available.

9.Poisonous baits –

  • Poisonous baits are food-like substances mixed with a pesticide specifically designed to attract and be eaten by insects or other pests and eventually poison them to death.
  • Baits are commonly used for rodent control, including mice and rats. However, baits are also used to control roaches, ants, flies, and other insects.
  • Bait formulations can be used indoors or outdoors.
  • When compared to ECs or other formulations, the percentage of active ingredient in a bait is low.
