Abstract
Ready-to-Dilute (RTD) herbicide formulations containing crop oil type adjuvants are disclosed which may be added as is to water to form a tank mix for herbicide application. The formulations are storage stable for extended periods, provide for rapid self-emulsification, form a stable tank mix, and moreover provide equal or better herbicidal efficiency than tank mixes containing commercially available standard crop oils and standard herbicide formulations.
Claims8
A ready-to-dilute herbicide composition comprising:
- (a) one or more herbicides selected from the group consisting of diphenylether herbicides, phenoxyphenoxy herbicides, imidazoline herbicides and cyclohexanone herbicides, in an amount of from 10 to about 250 g/L based upon the volume of the total composition;
- (b) an effective amount of a surface active emulsifier component comprising:
- (i) a polyoxyalkylene nonionic surfactant having an HLB of from 10 to about 14, and
- (ii) an anionic surfactant selected from the group consisting of the dialkylmetalsulfosuccinates and the metal alkylaromatic sulfonates;
- (c) optionally from 0 to about 100 g/l of a second surface active component comprising a polyoxyalkylene nonionic surfactant having an HLB of less than 10;
- and
- (d) about 100 g/L or more of one or more lower alkanol esters of a fatty acid,
- wherein said composition retains in excess of about 70 percent of its herbicidal activity after storage at about 40.degree. C. for one year.
