Pesticide formulations and application systems
Wettable powders WP are dry and powdery. Some agitation may be required to dissolve the soluble powder initially, but once a solution, agitation is not needed. Before combining various formulations, always consult the label or a pest control professional to find out whether the two formulations are compatible. These formulations may also require certification or training for individuals performing the application. Granules will not cling to plant foliage, so that they may be directly applied over plants or soil. Runoff or drift Rain soon after the application may cause the pesticide to run off and contaminate lakes, rivers, streams, or ponds. Pesticides that are physically different i. Many of the formulations used by farmers and commercial applicators like pest control companies need to be applied with certain equipment. These capsules are then suspended in a liquid.
These formulations may also require certification or training for individuals performing the application. How are incompatibilities avoided?
Granules will not cling to plant foliage, so that they may be directly applied over plants or soil. The percentage of active ingredient in a soluble powder is high compared to ECs and WPs, and there are not currently many SP formulations available.
If the physical properties of the formulation are not satisfactory go back to step 3 and proceed using a higher level emulsifier. When compared to ECs or other formulations, the percentage of active ingredient in a bait is low.
The percentage of active ingredient in a dust is generally quite low. The formulation is then ready to mix with water for application.
Here are some points to consider when choosing a formulation. The pesticide formulation is a mixture of active and other ingredients previously called inert ingredients.

A guide for private and commercial applicators: Applying pesticides correctly. When compared to ECs or other formulations, the percentage of active ingredient in a bait is low. Wettable powders are also more highly concentrated than dusts to contain more active ingredient. Specific environmental precautionary statements may be present on the label describing how to avoid runoff or drift. Examples of ready-to-use formulations used by homeowners are granules for insect and weed control and baits for rodent control. Synergists are a type of active ingredient that are sometimes added to formulations. Runoff or drift Rain soon after the application may cause the pesticide to run off and contaminate lakes, rivers, streams, or ponds. The type of surface, training, equipment, runoff, drift, habits of the pest, and safety are all considered when a manufacturer designs a pesticide formulation. NPIC fact sheets are designed to answer questions that are commonly asked by the general public about pesticides that are regulated by the U. Some liquid pesticide formulations commonly used by farmers and commercial applicators are applied with a compressed air sprayer, fogger, or soil injector.
