Foam-forming herbicidal composition and method of application.

摘要

Disclosed is a herbicidal liquid composition which comprises a herbicide-containing liquid and a specific amount of a surfactant. Such compositions can be formed into foam in use. The application of the liquid composition can be visually confirmed. Other advantages of the compositions are easy-handling, high efficiency and formation of a stable foam. Such compositions comprises at least one herbicide selected from water-soluble herbicides such as Bialaphos, oil-soluble herbicides such as Napropamide and insoluble herbicides such as Simazine in an amount of preferably 0.05 to 20% by weight of the composition; one or more optional agents selected from stabilizing agents, spreading agents, pastes, coloring agents, insecticides, germicides, fragrant agents and fertilizers; 0.1 to 20% by weight of a surfactant; and preferably 1.0 to 20 % by weight of at least one low-boiling solvent. Such compositions can be formed into a foam with a pressurizing apparatus such as an aerosol-forming apparatus, a trigger sprayer, a hand pump and an electrical pump, Excell and Enviro Systems.
