Abstract
The present invention provides microemulsifiable concentrates and microemulsions comprising azoxystrobin and propiconazole.
Claims22
A microemulsifiable concentrate comprising:
- a) azoxystrobin;
- b) propiconazole;
- c) an effective amount of an emulsifier system capable of forming a microemulsion of azoxystrobin and propiconazole upon dilution in water;
- and
- d) an effective amount of at least one solvent capable of dissolving or solubilizing azoxystrobin.
A method of improving the physical stability of an azoxystrobin microemulsion, said method comprising forming a microemulsifiable concentrate comprising azoxystrobin, propiconazole, an emulsifier system and at least one solvent capable of dissolving or solubilizing azoxystrobin and diluting said microemulsifiable concentrate with an appropriate amount of water to form a microemulsion, wherein said microemulsion exhibits improved physical stability compared to a similarly formulated azoxystrobin microemulsion which does not contain propiconazole.
A method of improving the physical stability of an azoxystrobin microemulsion, said method comprising forming a microemulsifiable concentrate comprising azoxystrobin, at least one solvent suitable for dissolving or solubilizing azoxystrobin and an emulsifier system suitable for forming an emulsion of azoxystrobin having an average emulsion particle size of between 0.01 and 0.1 micron upon dilution in water, and diluting said microemulsifiable concentrate to form a microemulsion, wherein propiconazole is mixed with the azoxystrobin prior to, during and/or after dilution of the azoxystrobin-containing microemulsifiable concentrate.
