ingredients, such as stabilizers or dyes.
How do you think the products listed below are
formulated? . Alpha 40 WP. Beta 80 DF. Gamma 5G. -
ANSWER-Product trade names often indicate formulation,
using standard abbreviations. In these examples, Alpha 40
WP is a wettable powder, Beta 80 DF is a dry flowable,
and Gamma 5G is a granule.

the machines produce and distribute very fine droplets.
What are invert emulsions? How are they typically used? -
ANSWER-Thick mixtures that contain a water- soluble
pesticide dispersed in an oil carrier. These products
require a special kind of emulsifier that allows the
pesticide to be mixed with a large volume of petroleum-
