Abstract

A process for treating plants, including the application of at least one compound, termed carbonic ester of glycerol, including at least one carboxylic ester function formed by a carbonic acid-derived group and at least one glycerol-derived group, with the exception of cyclic glyceryl carbonate including five ring members.

First claim

The invention claimed is:

1. A method for the treatment of plants, comprising:
applying to a plant at least one glycerol carbonic ester, with the exception of a cyclic glycerol carbonate having five ring members, the glycerol carbonic ester being selected from the group consisting of:
(i) linear glycerol carbonic esters having at least one group of atoms of general formula (I):

wherein
G 0 is selected from the group consisting of:
α/α′-acylated propylene groups of general formula (II):

β-acylated propylene groups of general formula (III):

the α/α′-hydroxylated propylene group of formula (IV):

the β-hydroxylated propylene group of formula (V):

wherein R1 and R2 are organic groups formed of elements selected from the group consisting of carbon (C), hydrogen (H) and oxygen (O); and

(ii) cyclic α/α′-acylated glycerol carbonic esters of general formula (VIII):

wherein R1 is an organic group formed of elements selected from the group consisting of carbon (C), hydrogen (H) and oxygen (O);
wherein the at least one glycerol carbonic ester is applied by contacting a part of the plant elected from the group consisting of a plant seed, a part of the plant above soil, an underground part of the plant, and combinations thereof.

2. The method of claim 1 , wherein the at least one glycerol carbonic ester is a linear acylated glycerol carbonic ester of general formula (X):

wherein:
x is an integer equal to 0 or to 1 which can vary in formula (X) according to each group of formula (X-a):

x not always being zero;
n is an integer from 1 to 20 inclusive;
Q 2 is a hydrogen (H) or an organic group formed of at least two atoms bonded by covalent bonds, said atoms being selected from the group consisting of carbon (C), hydrogen (H) and oxygen (O);
M 2 represents an organic group formed of at least two atoms bonded by covalent bonds, said atoms being selected from the group consisting of carbon (C), hydrogen (H) and oxygen (O); and
G 2 represents:
α/α′-acylated propyl group of the general formula (II); or
β-acylated propyl group of the general formula (III).

3. The method of claim 2 , wherein n is an integer from 1 to 10.

4. The method of claim 2 , wherein the linear α/α′-acylated glycerol carbonic ester of the general formula (X) has a molar mass greater than 400 g/mol.

5. The method of claim 1 , wherein R1 and R2 are aliphatic hydrocarbon groups having from 1 to 25 carbon atoms.

6. The method of claim 1 , wherein the at least one glycerol carbonic ester is applied in association with at least one active agent, other than a glycerol carbonic ester, selected from the group consisting of agents that act upon the germination of seeds, growth control agents, plant development agents, agents that stimulate photosynthesis, and nutriments for plants.

7. The method of claim 1 , wherein the at least one glycerol carbonic ester is applied by contacting the plant with a nutritive composition comprising at least one glycerol carbonic ester and at least one solid in the divided state comprising at least one compound selected from the group consisting of nutritive elements of plants.

8. The method of claim 1 , wherein the at least one glycerol carbonic ester is applied to plant seeds.

9. The method of claim 1 , wherein the at least one glycerol carbonic ester is applied to parts of plants above the soil.

10. The method of claim 1 , wherein the at least one glycerol carbonic ester is applied to underground parts of plants.
