Definitions
- the present invention relates to an agrochemical composition.
- the present invention is especially concerned with a stable and environmental-friendly emulsion in water (EW) pesticidal formulation comprising benzoylphenyl urea compounds active as an insecticides and an ether as the solvent.
- EW emulsion in water
- the present invention further relates to a method of preparing the aforementioned composition and their use in crop protection.
- the present invention is particularly concerned with the prevention of the crystallization of insecticidal benzoylphenyl urea derivatives and with the reduction of the phytotoxicity of EW emulsion formulations.
- Insect growth regulators known for use in controlling insects include benzoylphenyl urea (BPU) compounds, examples of which may be selected from among the commercially available compounds novaluron, lufenuron, hexaflumuron, triflumuron, diflubenzuron, chlorfluazuron, flufenoxuron, noviflumuron and teflubenzuron.
- BPU benzoylphenyl urea
- Benzoyphenyl urea compounds are generally commercialized in emulsion concentrate formulations. However, such formulations require substantial quantities of organic solvents such as aromatic hydrocarbons, chlorinated hydrocarbons, etc. which are known for their toxicological and ecotoxicological properties. The solvent-based formulation brings toxicity, environmental and odor problems. As a result, there is an ongoing need to develop an environmentally-friendly formulation for benzoylphenyl urea compounds.
- Emulsion in Water (EW) is an environmentally-friendly formulation. Examples of Emulsion in Water
- CN10137996 describes an Emulsion in Water (EW) formulation comprising 1-50% Lufenuron as active ingredient, a solvent in an amount of 1 %-10%, an antifreeze agent in an amount of 0.5%-5%, an antifoam agent in an amount of 0.1 %-1 %, an emulsifier in an amount of 1 %-10%, a thickener in an amount of 0.1 %-5% and water.
- EW Emulsion in Water
- this formulation is more environmentally acceptable than solvent-based Emulsion Concentrate formulations for the same active ingredient, the solvent used in the formulation is xylene or toluene, both of which can be very damaging to the environment.
- Aliphatic hydrocarbons suffer from their generally low solvent power to solid pesticides.
- the other solvents listed above, while suitable to solubilize the pesticide, are themselves soluble in water. Such a solubility in water causes the phenomenon of crystallization of the pesticide. Such crystallization makes the formulation unsuitable for spraying.
- the present invention provides a stable and environmentally-friendly Emulsion in Water (EW) pesticidal formulation.
- EW Emulsion in Water
- this invention relates to a use of certain C 2 -C 4 dialkylene glycol di-/mono- C C 4 alkyl ethers as the solvent in an EW composition comprising one or more benzoylphenyl ureas as active agrochemical ingredients.
- These ethers when used as solvents, are not only environmental friendly, but also advantageously reduce or prevent the crystallization of benzoylphenyl urea in the final formulation.
- the present invention provides an agrochemical composition

- the concentrated water emulsions of the present invention exhibit both a high degree of physical and chemical stability, in particular in a temperature range from -15°C to 55°C, in which no crystallization phenomena are observed during storage.
- the formulations also exhibit improved environmental friendliness.
- Benzoylphenyl ureas are water insoluble compounds. These compounds are commercially formulated into Emulsion Concentrate (EC) products. Substantive quantities of organic solvents such as xylene or toluene in Emulsion Concentrate formulations are problematic, in particular giving rise to pollution to the environment when the formulations are finally applied in use. Accordingly, there is an ongoing need to develop environmentally friendly formulations for benzoylphenyl urea compounds. Emulsion in Water formulation is one formulation that has the potential for reduced environmental impact. However, the solvents used in the EW formulation of benzoylphenyl ureas as active ingredient are similar with those used in EC formulation. As a result, the problem of environmental pollution remains present.
