Claims
- 1. A liquid herbicidal composition in the form of an emulsifiable concentrate or an aqueous suspension concentrate consisting essentially of an effective amount of Linuron as an active component in admixture with 0.05 to 2% by weight of a fat-soluble disazo dye selected from the group consisting of solvent red 23 (C.I. 26100), solvent red 24 (C.I. 26105), solvent red 27 (C.I. 26125) and solvent black 3 (C.I. 26150) wherein said disazo dye is present in an amount sufficient to inhibit the crystallization of said active component in aqueous emulsions of the emulsifiable concentrate or in aqueous suspension concentrates and the aqueous dilutions thereof.
- 2. The herbicidal composition of claim 1 containing 0.1 to 0.5% by weight of the fat-soluble disazo dye.
- 3. The liquid herbicidal composition of claim 1 in the form of an emulsifiable concentrate containing
- 10to 25% by weight of Linuron,
- 25 to 40% by weight of ketones,
- 60 to 18% by weight of aromatic solvents,
- 0.05 to 2% by weight of fat-soluble disazo dyes, and
- 4.95 to 15% by weight of emulsifier.
- 4. The liquid herbicidal composition of claim 3 containing 0.1 to 0.5% by weight of the fat-soluble disazo dye.
- 5. The liquid herbicidal composition of claim 3 wherein said ketones are isophorone or cyclohexanone or both.
- 6. The liquid herbicidal composition of claim 3 wherein said aromatic solvent contains up to 35% by weight of saturated hydrocarbons.
- 7. The liquid herbicidal composition of claim 1 in the form of an aqueous suspension concentrate containing
- 20 to 50% by weight of Linuron,
- 2 to 20% by weight of surface-active substances,
- 0 to 2% by weight of suspension auxiliaries,
- 0 to 2% by weight of defoamers,
- 0.05 to 2% by weight of fat-soluble disazo dyes,
- 0 to 4% by weight of antifreezing agents and water as balance to 100% by weight.
- 8. The liquid herbicidal composition of claim 7 containing 0.1 to 0.5% by weight of the fat-soluble disazo dye.
- 9. A method for combating weeds which comprises applying to a locus of weed growth a herbicidally effective amount of a composition as claimed in any one of claims 1, 2, 3, 4, 5, 6, 7 or 8 in the form of an aqueous dilution.
