Abstract
The present invention relates to insecticidal formulations for vector and pest control with increased contact efficacy, more particularly to insecticidal active ingredient—matrix particles and insecticidal compositions comprising such insecticidal active ingredient—matrix particles, as well as to methods and uses of such insecticidal formulations.
Claims15
Insecticidal active ingredient—matrix material particles with a particle size d50 of 0.1 to 75 microns, comprising
- a) at least one insecticidal active ingredient selected from the group consisting of isoxazolines, meta-diamides, arylpyrazolheteroarylamides and arylpyrazolarylamides, wherein the at least one insecticidal active ingredient is distributed in
- b) a matrix material comprising a wax.
Insecticidal active ingredient—matrix material particles with a particle size d50 of 0.1 to 75 microns comprising
- a) at least one insecticidal active ingredient selected from the group consisting of isoxazolines, meta-diamides, arylpyrazolheteroarylamides and arylpyrazolarylamides, wherein the at least one insecticidal active ingredient is distributed in
- b) a matrix material,
- wherein the insecticidal active ingredient—matrix material particle does not exhibit a melting peak of the active ingredient when measured in a second heating cycle after heating to a temperature of at least 20° C. above the melting point of the at least one insecticidal active ingredient at a steady heating rate using Differential Scanning Calorimetry.
The insecticidal active ingredient—matrix material particles according to claim1, wherein the at least one insecticidal active ingredient selected from the group consisting of 2-chloro-N-cyclopropyl-5-{1-[2,6-dichloro-4-(1,1,1,2,3,3,3-heptafluoropropan-2-yl)phenyl]-1H-pyrazol-4-yl}-N-methylnicotinamide, Broflanilide and 4-[(5S)-5-(3,5-dichloro-4-fluorophenyl)-5-(trifluoromethyl)-4,5-dihydro-1,2-oxazol-3-yl]-N-[(4R)-2-ethyl-3-oxo-1,2-oxazolidin-4-yl]-2-methylbenzamide.
(canceled)
A method to identify a useful matrix material for an insecticidal composition with Differential Scanning Calorimetry comprising:
- a) heating at least one insecticidal active ingredient selected from the group consisting of isoxazolines, meta-diamides, arylpyrazolheteroarylamides and arylpyrazolarylamides and a matrix material to be tested to a temperature of at least 20° C. above the melting point of the at least one insecticidal active ingredient at a steady heating rate in a first heating cycle of the Differential Scanning Calorimetry,
- b) retaining the maximal heating temperature of the first heating cycle for a period of at least 10 minutes,
- c) cooling the temperature is down to a temperature of between 0° C. to 40° C.,
- d) in a second heating cycle step, raising the temperature to a temperature of at least 20° C. above the melting point of the at least one insecticidal active ingredient at a steady heating rate, and
- e) identifying a useful matrix material in the case that the insecticidal active ingredient matrix material combination does not exhibit a melting peak when measured in the second heating cycle of the Differential Scanning Calorimetry.
