Claims32
A liquid pesticide formulation comprising:
- a) halosulfuron-methyl;
- b) one or more diluent(s), where the diluent(s) is a liquid comprising:
- i) a first carbon structure of at least six carbon atoms, the first carbon structure being a substituted or unsubstituted, saturated or unsaturated, linear or branched alkyl or heteroalkyl;
- ii) optionally one or more glyceryl, carbonyl, phenyl, sulfonyl, or phosphonyl group(s) on the first carbon structure,
- wherein if the first carbon structure of the diluent comprises a hydroxyl group(s), the hydroxyl group(s) is adjacent to a carbonyl, phenyl, sulfonyl, or phosphonyl group(s);
- c) optionally, one or more surfactant(s), wherein the one or more surfactant(s) comprise:
- i) a second carbon structure of at least six carbon atoms, wherein the second carbon structure is a substituted or unsubstituted, saturated or unsaturated, linear or branched alkyl or heteroalkyl;
- ii) optionally one or more glyceryl, carbonyl, phenyl, sulfonyl, or phosphonyl group(s) on the second carbon structure,
- wherein if the second carbon structure of the surfactant comprises a hydroxyl group(s), the hydroxyl group(s) is adjacent to a carbonyl, phenyl, sulfonyl, or phosphonyl group(s);
- d) one or more rheology modifier(s);
- and
- e) optionally, one or more buffer(s);
- wherein the liquid pesticide formulation exhibits 5% (w/w) or less loss of halosulfuron-methyl upon storage for 8 weeks at 40° C. measured using quantitative chromatography.
10 more elements
A liquid pesticide formulation comprising:
- 3-40% (w/w) halosulfuron-methyl;
- 40-95% (w/w) of one or more diluent(s), wherein the diluent is a liquid comprising:
- i) a first carbon structure of at least six carbon atoms, the first carbon structure being a substituted or unsubstituted, saturated or unsaturated, linear or branched alkyl or heteroalkyl;
- ii) optionally one or more glyceryl, carbonyl, phenyl, sulfonyl, or phosphonyl group(s) on the first carbon chain, wherein if the diluent comprises a hydroxyl group(s) in its chemical structure, the hydroxyl group(s) is adjacent to a carbonyl, phenyl, sulfonyl, or phosphonyl group(s);
- 0-20% (w/w) of one or more surfactant(s), wherein the surfactant is selected from sodium oleate, mono-C10-16-alkylesters, calcium lignosulfonate, sodium dioctyl sulfosuccinate, potassium phosphate monobasic/potassium phosphate dibasic, phosphate ester, sodium dodecylbenzene sulfonate, acrylic-styrene copolymer salt, or mono tertiary amine-PEG-trimerate, or mixtures thereof;
- and
- 1 to 10% (w/w) of one or more rheology modifier(s),
- wherein the liquid pesticide formulation exhibits 5% (w/w) or less loss of halosulfuron-methyl upon storage for 8 weeks at 40° C. measured using quantitative chromatography.
5 more elements
A liquid pesticide formulation comprising:
- 20-30% (w/w) halosulfuron-methyl;
- 40-82% (w/w) of one or more diluent(s), wherein the diluent is a liquid comprising:
- i) a first carbon structure of at least six carbon atoms, the first carbon structure being a substituted or unsubstituted, saturated or unsaturated, linear or branched, alkyl or heteroalkyl;
- ii) optionally one or more glyceryl, carbonyl, phenyl, sulfonyl, or phosphonyl group(s) on the first carbon chain, wherein if the diluent comprises a hydroxyl group(s) in its chemical structure, the hydroxyl group(s) is adjacent to a carbonyl, phenyl, sulfonyl, or phosphonyl group(s);
- 5-10% (w/w) of one or more surfactant(s), wherein the surfactant is selected from sodium oleate, mono-C10-16-alkylesters, calcium lignosulfonate, sodium dioctyl sulfosuccinate, potassium phosphate monobasic/potassium phosphate dibasic, phosphate ester, sodium dodecylbenzene sulfonate, acrylic-styrene copolymer salt, or mono tertiary amine-PEG-trimerate, or mixtures thereof;
- and
- 3-8% (w/w) of one or more rheology modifier(s),
- wherein the liquid pesticide formulation exhibits 5% (w/w) or less loss of halosulfuron-methyl upon storage for 8 weeks at 40° C. measured using quantitative chromatography.
5 more elements
A liquid pesticide formulation comprising:
- a) halosulfuron-methyl;
