| Application |
Mode of Action:
-
Thidiazuron is a new and efficient cytokinin for the plants, acting as a straight defoliant by stimulation of the leaf abscission layers, mainly used for cotton and peanut.
-
Thidiazuron is a plant growth regulator, absorbed by the leaves, which stimulates formation of an abscission layer between the plant stem and the leaf petioles, causing the dropping of entire green leaves.
Usage of Thidiazuron:
-
Thidiazuron is mainly used for defoliation of cotton, in order to facilitate harvesting.
-
Thidiazuron can be used for grape to improve fruit quality and increase yield.
-
Thidiazuron can be used for melon to improve fruit setting rate and increase yield.
-
Thidiazuron can be used for celery to keep leaves green.
-
Thidiazuron can be used for cucumber to promote fruit-bearing, increase weight of single fruit.
-
Thidiazuron can be used for flower cuttage with low concentration.
