Stable liquid formulations and methods of using the same

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 optionally including one or more heteroatom(s), the first carbon structure being linear, branched, cyclic or aromatic;
• ii) optionally one or more glyceryl, carbonyl, phenyl, sulfonyl, or phosphonyl group(s) on the first carbon structure,
• wherein the organic diluent(s) lack hydroxyl group(s) on the first carbon structure unless they are part of the optional 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 optionally including one or more heteroatom(s), wherein the second carbon structure is linear, branched, cyclic or aromatic;
• ii) optionally one or more glyceryl, carbonyl, phenyl, sulfonyl, or phosphonyl group(s) on the second carbon structure,
• wherein the surfactant(s) lack hydroxyl group(s) on the second carbon structure unless they are part of the optional carbonyl, phenyl, sulfonyl, or phosphonyl group(s);
• d) optionally, one or more rheology modifier(s);
• 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.

A liquid pesticide formulation comprising:

• 3-40% (w/w) halosulfuron-methyl;
• 40-95% (w/w) of one or more diluent(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
• 0-10% (w/w) rheology modifier.

A liquid pesticide formulation comprising:

• 20-30% (w/w) halosulfuron-methyl
• 40-82% (w/w) of one or more diluent(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).

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 optionally including one or more heteroatom(s), the first carbon structure being linear, branched, cyclic or aromatic;
• ii) optionally one or more glyceryl, carbonyl, phenyl, sulfonyl, or phosphonyl group(s) on the first carbon structure,
• wherein the organic diluent(s) lack hydroxyl group(s) on the first carbon structure unless they are part of the optional carbonyl, phenyl, sulfonyl, or phosphonyl group(s);
• c) one or more surfactant(s), wherein the one or more surfactant(s) comprise:
• i) a second carbon structure of at least six carbon atoms optionally including one or more heteroatom(s), wherein the second carbon structure is linear, branched, cyclic or aromatic;
• ii) optionally one or more glyceryl, carbonyl, phenyl, sulfonyl, or phosphonyl group(s) on the second carbon structure,
• wherein the surfactant(s) lack hydroxyl group(s) on the second carbon structure unless they are part of the optional carbonyl, phenyl, sulfonyl, or phosphonyl group(s);
• d) optionally, one or more rheology modifier(s);
• e) optionally, one or more buffering agents(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.
