Use of adjuvants to improve abscisic acid performance
View Patent ↗This invention relates to the use of selected adjuvants to improve the performance of S-(+)-abscisic acid (S-ABA, ABA) or ABA salts on plants.
1. A method for enhancing and extending the time of transpiration inhibition of abscisic acid (ABA) or salts thereof on plants by applying a composition comprising from about 125 ppm to about 1000 ppm of ABA or salts thereof and from about 0.01% w/w to about 0.5% w/w of at least one surfactant selected from Brij 58, Brij 76, Brij 78, Brij 98, Agral 90 and Latron B-1956 (a phtahlic/glycol alkyl resin) to plants.
2. The method of claim 1 wherein the composition further comprises a fertilizer.
3. The method of claim 1 wherein the surfactant is selected from Brij 98, Agral 90 and Latron B-1956.
4. The method of claim 2 wherein the fertilizer is a nitrogen-containing fertilizer selected from the group consisting of urea, ammonium nitrate and ammonium sulfate.
5. The method of claim 1 wherein the surfactant is selected from Brij 76, Brij 78, and Brij 98.
6. The method of claim 5 wherein the surfactant is Brij 98.
7. A method for enhancing and extending the time of transpiration inhibition of ABA or salts thereof on plants by applying a composition comprising from about 125 ppm to about 1000 ppm of ABA or salts thereof, from about 0.01% w/w to about 0.5% w/w of Brij 98, and a fertilizer to plants.
8. The method of claim 4 wherein the fertilizer is urea.
9. The method of claim 7 wherein the fertilizer is a nitrogen-containing fertilizer selected from the group consisting of urea, ammonium nitrate and ammonium sulfate.
10. The method of claim 9 wherein the fertilizer is urea.
