Adjuvants. Anything put in the spray tank other than the active ingredient is an adjuvant. They are put in to make the product work better. Examples of adjuvants are spreaders, stickers, dyes, etc.
Growth Regulator. These are products registered as pesticides that do not control pests but change the shape or appearance of the plant, stop or start plant growth, prevent flowering and other functions.
Molluscicide. Controls snails and slugs.
Organic Product. This is a tough one. Essentially, all the chemicals used are organic since they have carbon in their chemical structure. The exception would be Sulfur and Copper, these are a couple that are inorganic. Some people say if a product is naturally occurring its organic and it is man-made it’s not organic. Again, some materials are naturally occurring but can also be made synthetically. Agriculturally, products that claim to be organic must be approved by a governing board. This is not true of homeowner products. See also Organic Fertilizer, OMRI and NOP
Pesticide. A product used to control pests. They can be herbicides (weeds), insecticides (insects), miticides (mites), fungicides (diseases), rodenticides (rodent control) algaecides (algae) growth regulators and others. In fact, the chlorine you put in your pool is registered as a pesticide, since it controls algae, etc.
Surfactants. This means “surface active agents”. They are adjuvants that are usually spreaders or spreader stickers that spread the water droplet over the surface of the plant for better coverage and penetration.
