Protectant Granules contain active ingredients designed to protect something of value such as a crop, turf or home to name a few.  These granules can come in many shapes, sizes and densities depending on the target they are designed to achieve.  Typically, the granules are impregnated with an active ingredient at levels of up to 10%.  Types of granules include cellulose materials (like corn cobs), sand, limestone and clay.

Nutrients are granules designed to deliver essential elements to a desired plant species such as food crops, turf, house plants to name a few.  They also come in many shapes, sizes and densities but also represent a plethora of nutrients as well as characteristics or chemistries that are designed to alter the release of the nutrient to the desired target.  In general these granules are designed to bypass the crop and target the soil surface.  Nutrients granules offer a great deal of flexibility to the user and are typically much more cost effective than using a liquid nutrient source.  To learn more about fertilizers, visit WWW.tfi.org


These are combinations of nutrients and a protectant or combination of protectants that enable the user to deliver both in a single application.  These products offer many conveniences in time and costs.

Soil Active Granules

Soil activated granules are designed to bypass the plant and contact the soil surface. This is especially beneficial for nutrients, pre-emergent herbicides, and sub-surface insecticides. Granules that offer "dispersibility" when contacted with water offer many advantages over other granules in this category. Granules such as DGLite disperse when contacted with water (see how this works) which limits the potential of "pick-up" from non-targeted species like birds, as well as increased efficacy with the increased particles released after dispersal.
Foliar Active Granules

Foliar granules are designed to "perch" on the plant surface and are typically lightweight and small particle. The purpose of these granules is to deliver a chemical to the plant through its leaf tissue. These granules are beginning to close the efficacy gap between liquids and granules but require a great deal of sophistication to enable the desired chemistry to leave the granule and enter the leaf tissue.
Combination Granules

Combinations - many of the above delivery mechanisms can be combined to target multiple targets. Examples are: Weed and Feeds in which the weed control perches on the leaf surface and the nutrients fall to the soil and Fertilizer/Bait combinations which allow a user to fertilize and apply insect bait in one application.
Bait Granules

Baits are designed to attract a pest such as Fire Ant or Mole Cricket, which offer many advantages to the other granules. Since the targeted pest is attracted to this granule much less is required to destroy the pest. Baits can be spot applied or broadcast applied.
