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

The invention claimed is:

1. 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 comprising:
(i) an antioxidant;
(ii) a radiation manager;
and
(iii) a plant growth regulator;
wherein the antioxidant (i) comprises N-formyl urea, and
wherein the (iii) plant growth regulator comprises daminozide or prohexadione-Ca.

2. The method 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.

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

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

5. The method according to claim 1 , wherein the plant is growing under a condition of reduced water irrigation.

6. The method according to claim 1 , 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 method according to claim 1 , wherein the composition further comprises
(iv) a plant strengthener.

8. The method according to claim 7 , wherein the plant strengthener (iv) 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.

9. The method according to claim 7 , wherein the plant strengthener (iv) comprises a di- and mono-potassium salt of phosphorous acid.

10. The method according to claim 7 , wherein
the radiation manager (ii) comprises phthalocyanine green pigment.

11. The method according to claim 1 , wherein the (iii) plant growth regulator comprises daminozide.

12. The method according to claim 1 , wherein the (iii) plant growth regulator comprises prohexadione-Ca.
