Abstract

Presented herein are compositions comprising an antioxidant (i), a radiation manager (ii), and one or more of, a plant strengthener (iii), or a plant growth regulator (iv). Also presented herein are compositions comprising a plant strengthener (iii), and one or more of, an antioxidant (i), or a radiation manager comprising a polyoxyalkylene UV absorber (ii). Furthermore, methods of using the disclosed compositions are also provided.

First claim

What is claimed is:

1. A composition comprising:
(i) an antioxidant;
(ii) a radiation manager;
(iii) a plant strengthener, and optionally
(iv) a plant growth regulator,
wherein the antioxidant (i) comprises, N-formyl urea,
wherein the radiation manager (ii) comprises a phthalocyanine pigment,
wherein the plant strengthener (iii) comprises fosetyl aluminum, and
wherein the plant growth regulator (iv) comprises trinexapac-ethyl.

2. The composition according to claim 1 , wherein the plant growth regulator (iv) is present.

3. The composition according to claim 1 , wherein the antioxidant (i) is produced by a reaction of:
(a) a carboxylic acid having the formula RCOOH where R is selected from the group consisting of hydrogen, substituted and unsubstituted alkyl, allyl vinyl, and alkoxyl groups having from 1-6 carbon atoms, substituted and unsubstituted phenyl group, and halides; with
(b) a urea having the formula (NHR')2CO where each R′ is the same or different and is selected from the group consisting of hydrogen, substituted and unsubstituted alkyl groups having from 1-6 carbon atoms, substituted and unsubstituted alkoxyl groups having from 1-6 carbon atoms, substituted and unsubstituted phenyl groups, and halides, wherein the carboxylic acid (a) is formic acid.

4. A method for improving one or more of plant quality, density, color, or plant cell turgidity, comprising: applying to a plant or soil a composition according to claim 1 .

5. The method according to claim 4 , wherein the plant is growing under a condition of reduced water irrigation.

6. The method according to claim 4 , wherein the treated plant exhibits improved green color, higher chlorophyll content, improved shoot density, and/or better plot soil moisture when compared to a non-treated plant before, during, and/or after the condition of reduced water irrigation.

7. The composition according to claim 1 , comprising about 1 to about 10% w/w of the antioxidant based on the total weight of the composition.

8. The composition according to claim 2 , wherein
the antioxidant (i) comprises N-formyl urea;
the radiation manager (ii) comprises phthalocyanine green pigment; and
the plant growth regulator (iv) comprises trinexapac-ethyl.

9. The composition according to claim 1 , which is synergistic.

10. The composition according to claim 1 , wherein
the antioxidant (i) comprises N-formyl urea;
the radiation manager (ii) comprises phthalocyanine green pigment; and
the plant strengthener (iii) comprises fosetyl-A1.

11. The composition according to claim 1 , wherein the plant growth regulator (iv) is not present.

12. The composition according to claim 10 , wherein the plant growth regulator (iv) is not present.
