A material that can be added to spray mixtures to lower the pH.
A material that increases the biological efficacy of agrichemicals.
A component of the formulation that produces a specific effect for which the formulation is designed.
A material added to a tank mix to aid or modify the action of an agrichemical, or the physical characteristics of the mixture.
A surface-active agent in which the active portion of the molecule containing the lipophilic segment forms exclusively a negative ion (anion) when placed in aqueous solution.
A material used to inhibit or prevent the formation of foam.
A material that attracts specific pests.
A compound or mixture that, when contained in solution, causes the solution to resist change in pH. Each buffer has a characteristic limited range of pH over which it is effective.
An adjuvant that increases the penetration of the spray material into the crop canopy. See deposition aid.
A surface-active agent in which the active portion of the molecule containing the lipophilic segment forms exclusively a positive ion (cation) when placed in aqueous solution.
A material used to alter the color of the tank mix.
A surface-active agent that allows simultaneous application of liquid fertilizer and agrichemical, or two or more agrichemical formulations, as a uniform tank mix, or improves the homogeneity of the mixture and the uniformity of the application.
An emulsifiable, petroleum oil-based product containing 15% to 20% w/w surfactant and a minimum of 80% w/w phytobland oil.
An emulsifiable, petroleum oil-based product containing up to 5% w/w surfactant and the remainder of a phytobland oil.
See phytobland oil.
A material that eliminates or suppresses foam in the spray tank.
A material that improves the ability of agrichemical sprays to deposit on target surfaces.
A horticultural spray oil applied during the dormant phase of the targeted plant.
A material used in liquid spray mixtures to reduce spray drift.
A surfactant that promotes the suspension of one immiscible liquid in another.
The process of reacting fatty acids with an alcohol. Although methanol is the most commonly used alcohol (methylated), ethanol (ethylated), n-butanol and isopropyl alcohol could be used.
A material that reduces the evaporation rate of a spray mix during, after, or both during and after, application.
A material that increases the effective life of an agrichemical after application.
See defoaming agent.
A material that increases the volume or stability of the foam formed in a spray mixture.
A material which increases the equilibrium water content and increases the drying time of an aqueous spray deposit.
An oil extracted from seeds that has been chemically modified (for example, methylated).
An emulsifiable, chemically modified vegetable oil product containing 5% to 20% w/w surfactant and the remainder chemically modified vegetable oil.
A petroleum oil containing a majority of the naphtha fraction.
A surface-active agent having no ionizable polar end groups but comprised of hydrophilic and lipophilic segments.
See petroleum, vegetable, paraffinic and so forth.
A petroleum oil (derived from paraffin crude oil) whose paraffinic-carbon type content is typically greater than 60%.
A material that enhances the ability of an agrichemical to enter a substrate or penetrate a surface.
Oil derived from petroleum: contains a mixture of hydrocarbons that are broadly classified as paraffins, naphthenes, aromatics, or other unsaturates, or combinations thereof.
A highly refined paraffinic material with minimum unsulfonated residue of 92% v/v.
A material which increases the area that a droplet of a given volume of spray mixture will cover on a target.
A material that has the properties of both a spreader and a sticker.
A material that assists the spray deposit to adhere or stick to the target and may be measured in terms of resistance to time, wind, water, mechanical action or chemical action.
A material that when added to a liquid agent medium, modifies the properties of the medium at a surface or interface. This is a general term that includes soluble detergents in liquid medium, dispersing agents, emulsifying agents, foaming agents, penetrating agents and wetting agents.
See surface agent.
Oil extracted from seeds; typically those of corn, cotton, peanut, rapeseed, sunflower, canola or soybean.
An emulsifiable vegetable oil product containing 5% to 20% w/w surfactant and a minimum of 80% w/w vegetable oil.
Wetting agents can be considered synonymous with spreading agents in function.
