Liquid herbicides that contain isoproturon and their use in a method for controlling weeds

摘要

1. Liquid, herbicidal agents in the form of aqueous suspension concentrates containing, as the active compound, isoproturon or mixtures of isoproturon with ioxynil, bromoxynil, mecoprop or salts of the last three active compounds and also formulating auxiliaries, which contain, as the formulating auxiliary, an alkali metal salt, preferably the sodium salt, of a condensation product containing sulfo groups and formed from a phenol and formaldehyde, and also alkali metal salts, ammonium salts or amine salts, preferably sodium salts, of alkyl polyglykol etherphosphate partial esters, in particular mono-(alkyl polyglycol ether)-phosphates or di-(alkyl polyglycol ether)-phosphates, the alkyl polyglykol ether radical of which consist of optionally substituted alkyl groups which can also contain double bonds and have preferably 6 to 24 and in particular 12 to 18 C atoms, and polyglycol ether groups having preferably up to 20 and in particular 4 to 12 ethylene oxide units (= EO units) per radical, the suspension concentrates having a temperature/viscosity coefficient of about 0.6 to 0.95, calculated on temperature increases in 20 degrees C intervals, within the temperature range from 10 to 70 degrees C, in particular 20 to 60 degrees C.
