Abstract
Aerial spray or discharge drift is controlled in aqueous compositions via the use of selected non-visco-elastic amounts of guar, one or more derivatives of guar, or combinations thereof.
Claims4
An aqueous spray drift reducing composition comprising at final dilution:
- a) a major mount of water;
- and
- b) a drift control agent composition comprising:
- i) from about 0.01 to about 0.275% by weight per unit volume of a guar composition selected from the group consisting of hydroxypropyl guar carboxymethyl hydroxypropyl guar, and combinations thereof;
- and
- ii) a compound known to function as a drift control agent with the proviso that the compound in said aqueous composition be present only in a Newtonianly effective amount.
