Abstract
The present invention provides a novel herbicidal aqueous solution or suspension concentrate composition comprising a herbicidally active agent with excellent chemical and physical stability as well as excellent redispersibility characteristics and a fumed alumina as a stabilizer.
Description
The present invention relates to the field of agrochemical formulations.
In order to be able to effectively remove or control unwanted plants, it is desirable to use effective chemical agents of herbicides. Compositions comprising two or more herbicides are desirable in certain agricultural areas and related efforts since they extend the spectrum or range of unwanted plant species that are killed or controlled.
Since it is desirable to have a composition having the above-mentioned characteristics, it is useful to use a combination of herbicides that promote the control of multiple weeds by applying a single herbicide. Combinations of insecticides are known and are available as a mixed solution of the active ingredients in their commercially available preparations. One method of making such compositions is referred to as "tank mixing ", wherein the components of their commercially available form are mixed by a user with a quantity of water. Tank mixes require end-users to purchase more than one commercial product, store them, calculate the exact amount of each active ingredient, meter these quantities into a mix, and dispose of multiple containers as appropriate. Tank mixing of two or three different commercial formulations often results in physical instability causing precipitation, aggregation, phase separation, etc. of the active ingredients, thus providing a non-uniform distribution of active ingredients. While it is advantageous to combine the active ingredients into one formulation, it is often more complicated due to the very different physical properties of the active ingredients, where chemical and physical stability is a problem.
The present invention provides a novel herbicidal aqueous suspoemulsion or aqueous suspension concentrate composition comprising a fumed alumina as a herbicidal and stabilizing agent with excellent chemical and physical stability as well as excellent redispersion properties do.
The present invention provides a novel herbicidal water-in-vivo suspension emulsion or aqueous suspension concentrate composition comprising a herbicidally active and a fumed alumina as a stabilizer, with excellent re-dispersing properties as well as excellent chemical and physical stability.
In one embodiment, the present invention is directed to a herbicide comprising atrazine, pyroxasulfone and fluthiacet-methyl, which have excellent chemical and physical stability as well as excellent redispersion characteristics To a novel aqueous suspoic emulsion composition.
Specifically, the aqueous suspoic emulsion compositions of the present invention comprise:
