wherein
Het 1 represents 3-pyridyl,
R 1 represents hydroxyl,
R 2 and R 3 represent propionyloxy or optionally substituted cyclic C 3-6 alkylcarbonyloxy, and
R 4 represents hydroxyl,
optionally substituted cyclic C 3-6 alkylcarbonyloxy,
optionally substituted benzoyloxy, or
optionally substituted saturated or unsaturated five- or six-membered heterocyclic carbonyloxy, provided that
a compound wherein
Het 1 represents 3-pyridyl,
R 1 represents hydroxyl,
R 2 and R 3 represent propionyloxy, and
R 4 represents hydroxyl,
is excluded.
2. The compound according to claim 1 or an agriculturally and horticulturally acceptable salt thereof, wherein
R 2 and R 3 represent optionally substituted cyclic C 3-6 alkylcarbonyloxy, and
R 4 represents hydroxyl, optionally substituted cyclic C 3-6 alkylcarbonyloxy, or optionally substituted benzoyloxy.
3. The compound according to claim 1 or an agriculturally and horticulturally acceptable salt thereof, wherein
R 2 and R 3 represent propionyloxy, and
R 4 represents optionally substituted cyclic C 3-6 alkylcarbonyloxy or optionally substituted saturated or unsaturated five- or six-membered heterocyclic carbonyloxy.
