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

1 . A composition comprising:
(i) an antioxidant; (ii) a radiation manager; and one or more of (iii) a plant strengthener, or (iv) a plant growth regulator.

2 . The composition according to claim 1 , wherein the plant strengthener (iii) is present.

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

4 . The composition according to claim 1 , wherein the antioxidant (i) is at least one selected from the group consisting of a safener, vitamin, strobilurin, and mono- and/or di-acyl urea containing derivative.

5 . 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')2C0 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.

6 . The composition according to claim 5 , wherein the carboxylic acid (a) is formic acid.

7 . The composition according to claim 1 , wherein the antioxidant (i) is at least one selected from the group consisting of

wherein R1, R2, R3, and R4 are the same or different and are selected from the group consisting of hydrogen, substituted and unsubstituted alkyl, allyl, vinyl and alkoxyl groups having from one to six carbon atoms, substituted and unsubstituted phenyl groups, and halides.

8 . The composition according to claim 1 , wherein the antioxidant (i) comprises N′, N′-diformyl urea.

9 . The composition according to claim 1 , wherein the radiation manager (ii) comprises:
(a) a colorant that screens UV and high energy visible blue light, and/or (b) a salt or oxide of a higher atomic weight metal that is micronized or in the form of a nanoparticle.

10 . The composition according to claim 1 , wherein the radiation manager (ii) comprises a phthalocyanine copper pigment.

11 . The composition according to claim 1 , wherein the radiation manager (ii) comprises a polyoxyalkylene UV absorber.

12 . The composition according to claim 2 , wherein the plant strengthener (iii) is at least one selected from the group consisting of a phosphite, phosphonate, phosphorous containing compound and salt thereof, inducer of systemic resistance, and plant hormone.

13 . The composition according to claim 2 , wherein the plant strengthener (iii) comprises a di- and mono-potassium salt of phosphorous acid.

14 . The composition according to claim 2 , wherein the antioxidant (i) comprises
N′, N′-diformyl urea; the radiation manager (ii) comprises phthalocyanine green pigment; and the plant strengthener (iii) comprises di- and mono-potassium salts of phosphorous acid.

15 . The composition according to claim 2 , wherein the antioxidant (i) comprises
N′, N′-diformyl urea; the radiation manager (ii) comprises phthalocyanine green pigment; and the plant strengthener (iii) comprises fosetyl-Al.

16 . The composition according to claim 3 , wherein the antioxidant (i) comprises
N′, N′-diformyl urea; the radiation manager (ii) comprises phthalocyanine green pigment; and the plant growth regulator (iv) comprises trinexapac-ethyl.

17 . A method for making a composition according to claim 1 , comprising:
(i) producing at least one antioxidant by reacting
(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; and
(b) a urea having the formula (NHR′)2C0 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;
(ii) mixing the antioxidant produced in step (i) with:
at least one radiation manager and with one or more of a plant strengthener or a plant growth regulator.

18 . 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 .

19 . The method according to claim 18 , wherein the plant is growing under a condition of reduced water irrigation.

20 . The method according to claim 18 , 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.

21 . A composition comprising:
(iii) a plant strengthener; and one or more of (i) an antioxidant, or (ii) a radiation manager comprising a polyoxyalkylene UV absorber.

22 . The composition according to claim 21 , wherein the plant strengthener (iii) is at least one selected from the group consisting of mono and di-potassium salt, fosetyl-Al, and trinexapac- ethyl.

23 . The composition according to claim 21 , wherein the antioxidant (i) is present.

24 . The composition according to claim 21 , wherein the radiation manager comprising a polyoxyalkylene UV absorber (ii) is present.

25 . The composition according to claim 23 , wherein the antioxidant (i) is at least one selected from the group consisting of N′, N′-diformyl urea, mefenpyr, trifloxystrobin, vitamin C, and sebacic acid.
