Agricultural pesticide compositions
An adjuvant composition for modifying the spray properties of an aqueous pesticide composition contains (a) at least one fatty deposition control agent, and (b)(ii) a liquid medium, one or more hydrotropes, and, optionally one or more surfactants, or (b)(ii) one or more surfactants, and adjuvant compositions for modifying the spray properties of an aqueous pesticide composition contains (c) at least one deposition control agent, and (d)(ii) a liquid medium, one or more hydrotropes, and, optionally one or more surfactants, or (d)(ii) one or more surfactants, and use thereof in agricultural applications.
1. A method for improving deposition control of an aqueous pesticide composition during a spray application, comprising:
contacting an aqueous pesticide composition with an adjuvant composition, wherein the adjuvant composition consists of, based on 100 parts by weight of the adjuvant composition:
from 60 to 90 pbw of at least one fatty deposition control agent selected from the group consisting of canola oil and soybean oil, and
from 10 to 40 pbw of at least one surfactant consisting of an ethoxylated glycol ester of fatty acid;
wherein an end use pesticide composition comprises the aqueous pesticide composition and the adjuvant composition and wherein the end use pesticide composition comprises, based on 100 pbw of the end use pesticide composition:
an aqueous medium,
from greater than 0 to about 20 pbw of one or more pesticide compounds;
from 0.1 to 10 pbw of the at least one fatty deposition control agent, wherein the at least one fatty deposition control agent comes from the adjuvant composition,
optionally, one or more hydrotropes;
and wherein the adjuvant composition forms a stable emulsion upon dilution into the pesticide composition; and spray applying the end use pesticide composition to a target pest and/or to the environment of the target pest, wherein the spray applying uses an air induction nozzle or a flat fan nozzle and wherein droplets comprising the aqueous pesticide composition and the adjuvant composition have greater than 60% of the droplets in the 150 to 500 pm range exiting the nozzle when the flat fan nozzle is used and greater than 70% of the droplets in the 150 to 500 pm range exiting the nozzle when the air induction nozzle is used,
wherein the spray applied end use pesticide composition exhibits improved deposition control compared to the aqueous pesticide composition when spray applied.
2. The method of claim 1 , wherein the at least one fatty deposition control agent is present at least at 80 wt % of the adjuvant composition and the at least one surfactant is present at least at 15 wt % of the adjuvant composition.
3. The method of claim 1 , wherein the pesticide comprises one or more herbicide compounds selected from glyphosate, its water soluble salts and esters, and mixtures thereof.
4. The method of claim 1 , wherein the at least one fatty deposition control agent is present at least at 80 wt % of the adjuvant composition.
5. The method of claim 1 , wherein the at least one surfactant is present at least at 15 wt % of the adjuvant composition.
6. The method of claim 1 , wherein the spray applied end use pesticide composition exhibits improved drift control properties compared to the aqueous pesticide composition when spray applied.
7. The method of claim 1 , wherein the spray applied end use pesticide composition exhibits improved anti-rebound properties compared to the aqueous pesticide composition when spray applied.
8. The method of claim 1 , wherein the at least one fatty deposition control agent consists of canola oil.
9. The method of claim 1 , wherein the at least one fatty deposition control agent consists of soybean oil.
10. The method of claim 1 , wherein the at least one fatty deposition control agent consists of canola oil and soybean oil.
11. A method for improving deposition control of an aqueous pesticide composition during a spray application, comprising:
contacting an aqueous pesticide composition with an adjuvant composition, wherein the adjuvant composition consists of, based on 100 parts by weight of the adjuvant composition:
from 60 to 90 pbw of at least one fatty deposition control agent selected from the group consisting of canola oil and soybean oil,
and from 10 to 40 pbw of at least one surfactant consisting of an ethoxylated glycol ester of fatty acid;
wherein an end use pesticide composition comprises the aqueous pesticide composition and the adjuvant composition and wherein the end use pesticide composition comprises, based on 100 pbw of the end use pesticide composition:
an aqueous medium,
from greater than 0 to about 20 pbw of one or more pesticide compounds;
from 0.1 to 10 pbw of the at least one fatty deposition control agent, wherein the at least one fatty deposition control agent consists of the at least one fatty deposition control agent from the adjuvant composition,
optionally, one or more hydrotropes;
and wherein the adjuvant composition forms a stable emulsion upon dilution into the pesticide composition; and
spray applying the end use pesticide composition to a target pest and/or to the environment of the target pest, wherein the spray applying uses an air induction nozzle or a flat fan nozzle and wherein droplets comprising the aqueous pesticide composition and the adjuvant composition have greater than 60% of the droplets in the 150 to 500 pm range exiting the nozzle when the flat fan nozzle is used and greater than 70% of the droplets in the 150 to 500 pm range exiting the nozzle when the air induction nozzle is used,
wherein the spray applied end use pesticide composition exhibits improved deposition control compared to the aqueous pesticide composition when spray applied.
