STABLE DEFOAMERS FOR HIGH ELECTROLYTE AGRICULTURAL FORMULATIONS

摘要

High electrolyte agrochemical formulations with reduced foaming are formulated with a polyorganosiloxane defoamer containing defoaming polyoxyalkylene ether groups and tertiary aminoalkyl groups. The defoamers are stable in the high electrolyte formulation.

主权项

1. A high electrolyte aqueous agrochemical composition resistant to foaming, comprising:
a) at least one agrochemical active: b) at least one surfactant; and c) an effective defoaming amount of at least one stable defoamer containing
organopolysiloxane groups, tertiary aminoalkyl groups or an ammonium salt thereof, and at least one ofc)i) polyether group(s) containing both polyoxyethylene moieties and polyoxyalkylene moieties where the alkylene groups are propylene or butylene groups or both; and/or
c)ii) both at least one polyoxyethylene polyether group and at least one polyoxy(propylene and/or butylene) polyether group.
