Embodiment 1

[0115] Example 1: The following items were mixed together (see Table E1).

[0116]

[0117] ATLOX 4914 T 36 (registered trademark of Unichema Chemie BV) is an alkyd-PEG resin and used as an emulsifier, which is available from Unichema Chemie BV.

[0118] ATLAS G-5000 F (registered trademark of Unichema Chemie BV) is a hydrophilic AB block copolymer and is used as an emulsifier, which is available from Unichema Chemie BV.

[0119] Dissolve clocloclofenac in a mixture of Aromatic 200 and n-butyl lactate. The emulsifier is then mixed into the mixture. Finally, water is added and the mixture is turned into emulsifiable cream (EW) by mechanical stirring. Precipitation of cloclofenac-ethyl hydrate was not observed.

Embodiment 2

[0121]

[0122] In Table E2,

[0123] "A200" means Aromatic 200.

[0124] "BL" means n-butyl lactate.

[0125] "CQC" means the percentage by weight (wt %) of the clocloclofenac-ethyl in the form of solution based on the total weight of A200+BL+CQC before adding water. "P" means that the cloclofenac hydrate was precipitated from the mixture.

[0126] "S" means that the cloclofenac-ethyl hydrate did not precipitate out of the mixture.

[0127] Dissolve CQC in A200, BL, or a mixture of A200+BL. After that, about 10 wt% of water based on the total weight of the sample (A200+BL+CQC) was added to each sample. Each sample was prepared at 4°C.

[0128] In order to maintain the solution form of cloclofenac-ethyl hydrate, each of A200 (100%) and BL (100%) can only have a CQC of less than 7 wt% when mixed with water. However, a 50 / 50 mixture of A200 and BL synergistically maintained a CQC of about 14 wt% in solution.

Abstract

A composition comprising at least one aromatic compound and at least one lactate ester compound is provided. Optionally, said composition can further comprise Cloquintocet-mexyl. Optionally, said composition can further comprise at least one emulsifier. Optionally, said composition can further comprise at least one herbicide. Processes comprising mixing such components are provided. Processes for controlling weeds or grasses or both with such compositions are provided.

Description

[0001] Cross-references to related applications [0002] This application claims priority from Provisional Application 60 / 841,268, filed in the United States Patent Office on August 30, 2006. Technical field [0003] The field of the invention is agriculturally useful compositions. Background technique [0004] Cloquintocet-mexyl (Cloquintocet-mexyl) has the following structural formula [0005] [0006] Mesopropyl is known to be used as a herbicide safener. Generally speaking, herbicide safeners are compounds that reduce the effectiveness of herbicides when applied to crops. [0007] One way to formulate pyrotropin for agricultural use is as a liquid concentrate. One example is an emulsifiableconcentrate ("EC") containing herbicide, an organic solvent and an emulsifier, which can be tank mixed with a separate herbicidal product containing herbicide and water. The organic solvent may also contain other active ingredients or even more of the same ingredients in the aqu...
