使用
Thidiazuron is a non-purine containing urea derivative with cytokinin activity.
Thidiazuron is used as a cotton defoliant and a plant growth regulator in tissue culture.
一般的な説明
Thidiazuron is a systemic herbicide, widely employed as an effective plant growth regulator and pre-harvest defoliant for crops such as cotton.

Soil. The reported half-life in soil is approximately 26–144 days (Hartley and Kidd,
1987).
Photolytic. Rapidly converted to the photoisomer, 1-phenyl-3-(1,2,5-thiadiazol-3-
yl)urea (Worthing and Hance, 1991). When thidiazuron adsorbed by soil was exposed to
UV light (λ <290 nm), 1-phenyl-3-(1,2,5-thiadiazol-3-yl)urea formed as the majo
