Abstract
The present invention relates to stable combined dispersions of at least one dithiocarbamate fungicide and at least one acid-based pesticide, and/or derivative thereof in a liquid carrier, wherein said dispersion is stabilized by inclusion of at least one organic phosphoric acid ester-based compatibility agent and wherein said dispersion is characterized by an improvement in the stability, compatibility, and suspensibility of the dispersion defined by a reduction in the rate and/or extent of phase separation and/or sedimentation. The invention further relates to methods for preparing and using said combined dispersions and methods for identifying useful organic phosphoric acid ester-based compatibility agents.
Claims57
A stable combined dispersion of at least one dithiocarbamate fungicide and at least one acid-based pesticide or derivative thereof, and/or derivative thereof in a liquid carrier, wherein said dispersion is stabilized by inclusion of at least one organic phosphoric acid ester-based compatibility agent and wherein said dispersion is characterized by an improvement in the stability, compatibility, and suspensibility of the dispersion defined by either or both,
- a. a reduction in the rate and/or extent of phase separation and/or sedimentation as compared with a combined dispersion of the same amount of the same dithiocarbamate fungicide and the same amount of the same acid-based pesticide in the absence of the compatibility agent, over comparable periods of time, or
- b. the sediment volume is equal or less than 2% of the volume of the combined dispersion when left to stand undisturbed for a period of 10, preferably 30 minutes.
A combination of (1) at least one dithiocarbamate fungicide, (2) at least one acid-based pesticide and (3) at least one alkyl polyalkylene glycol ether phosphoric acid ester acid form.
A combination of (1) at least one dithiocarbamate fungicide, (2) at least one acid-based pesticide and/or derivative thereof, (3) at least one alkyl polyalkylene glycol ether phosphoric acid ester acid form, and (4) water.
A combination comprising (1) at least one dithiocarbamate fungicide (2) at least one acid-based pesticide in salt form (3) at least one alkyl polyalkylene glycol ether phosphoric acid ester acid form and optionally, (4) one or more additional pesticides.
A combination comprising (1) at least one dithiocarbamate fungicide (2) at least one acid-based pesticide in salt form (3) at least one alkyl polyalkylene glycol ether phosphoric acid ester acid form and optionally, (4) one or more additional pesticide.
A combination comprising (1) an amount of at least one dithiocarbamate fungicide (2) an amount of at least one acid-based pesticide in salt form (3) an amount of at least one alkyl polyalkylene glycol ether phosphoric acid ester acid form (4) water, and optionally (5) at least one additional pesticide.
A process for preparing a suspension comprising mixing (1) at least one dithiocarbamate fungicide, (2) at least one acid-based pesticide and/or derivative thereof, (3) at least one alkyl polyalkylene glycol ether phosphoric acid ester acid form and (4) water.
A package comprising (1) at least one dithiocarbamate fungicide, (2) at least one acid-based pesticide and/or derivative thereof and (3) at least one alkyl polyalkylene glycol ether phosphoric acid ester acid form.
A package comprising (i) at least one alkyl polyalkylene glycol ether phosphoric acid ester acid form and (ii) (1) at least one composition comprising at least one dithiocarbamate fungicide and/or (2) at least one composition comprising at least one acid-based pesticide and/or derivative thereof.
A kit for preparing a combination comprising (i) at least one alkyl polyalkylene glycol ether phosphoric acid ester acid form and (ii) (1) at least one composition comprising at least one dithiocarbamate fungicide and (2) at least one composition comprising at least one acid-based pesticide and/or derivative thereof.
Use of at least one alkyl polyalkylene glycol ether phosphoric acid ester acid form for dispersing at least one dithiocarbamate fungicide and at least one acid-based pesticide and/or derivative thereof into a stable combined dispersion in a liquid carrier.
Use of at least one alkyl polyalkylene glycol ether phosphoric acid ester acid form for reducing the rate and/or extent of phase separation and/or sedimentation of an aqueous suspension comprising (1) at least one dithiocarbamate fungicide and (2) at least one acid-based pesticide, wherein the rate and/or extent of phase separation and/or sedimentation of the suspension is lower than the rate and/or extent of phase separation and/or sedimentation of a comparable aqueous suspension when the at least one dithiocarbamate fungicide and the at least one acid-based pesticide are combined in the absence of said alkyl polyalkylene glycol ether phosphoric acid ester acid form over comparable time periods.
A mixture of mancozeb, prothioconazole and glyphosate.
A mixture of mancozeb, prothioconazole, picoxystrobin and glyphosate.
A method for use in identifying an acceptable organic phosphoric acid ester-based compatibility agent capable of reducing the rate and/or extent of phase separation and/or sedimentation of an aqueous dispersion comprising a dithiocarbamate fungicide and an acid-based pesticide or salt thereof, the protocol comprising the steps of combining the compatibility agent candidate, the dithiocarbamate fungicide and the acid-based pesticide or salt thereof and water as a dispersion in a container, optionally inverting the container between addition of each component and again after all components are incorporated, allowing the dispersion to stand undisturbed for a period of time, and recording the sedimentation volume after 10 minutes, wherein when the sediment volume is equal or less than 2% of the volume of the dispersion an acceptable compatibility agent is identified.
