Abstract
The disclosure relates to organosulfur containing compositions, in particular di-n-propyl thiosulfonate (PTSO) and di-n-propyl thiosulfinate (PTS), di-methyl thiosulfonate, di-phenyl thiosulfonate. Such compositions are useful for as biostimulants for plants. In particular such compositions may result in increased nutrient use efficiency, increased tolerance to abiotic stress, and/or improved quality characteristics. Compositions comprising said organosulfur compounds are also provided for agricultural use.

A method, comprising providing to a plant a compound according to Formula I, or a composition comprising a compound according to Formula I:
- Formula I, wherein n is 2;
- wherein one X is —S— and the other X is selected from the group consisting of —S—, —S(O)—, and —S(O)2—;
- and R1 and R2 are independently selected from the group consisting of optionally substituted alkyl, optionally substituted aryl, optionally substituted heteroalkyl, optionally substituted heteroaryl, optionally substituted alkenyl, optionally substituted alkynyl, optionally substituted cycloalkyl, and optionally substituted heterocycloalkyl.
An agricultural composition comprising a compound according to Formula I:
- Formula I, wherein n is 2;
- wherein one X is —S— and the other X is selected from the group consisting of —S—, —S(O)—, and —S(O)2—;
- and R1 and R2 are independently selected from the group consisting of optionally substituted alkyl, optionally substituted aryl, optionally substituted heteroalkyl, optionally substituted heteroaryl, optionally substituted alkenyl, optionally substituted alkynyl, optionally substituted cycloalkyl, and optionally substituted heterocycloalkyl;
