The emulsifiable concentrate is a preparation of the toxicant, a solvent and the emulsifier which is often some form of detergent. Emulsifiable concentrates are almost always diluted with water, but can be diluted with oil to form an oil solution. Occasional agitation may be necessary during use. Emulsions can be used on synthetic organic materials around heat or open flames and with care on vegetation. Suspensions must be used with machines that provide constant agitation.
Suspensions diapered by a portable compressed sprayer also require frequent agitation.
Dust is a mixture of a toxicant plus an inert base usually consisting of a finely ground form of bentonite, pyrophyllite, or talc. These mixtures are used as indoor and outdoor residuals and for animal applications. Granules or pellets are preparations of pesticide impregnated into particles of highly absorptive clays and earths which are graded by sizes ranging from coarse pebble-like pellets to those with a consistency of fine sand. Granules and pellets with greater particle weight have a minimized drift, thus, preventing undesirable contamination of areas bordering those being treated. The moat useful adze range is from 15 to 40 mesh.
