Document Type and Number:
WIPO Patent Application WO/2019/010716
Kind Code:
A1
Abstract:
The present invention relates to a dicarfentrazone-ethyl crystalline form D, and a preparation method therefor and a use thereof. The X-ray powder diffraction pattern of the dicarfentrazone-ethyl crystalline form D has characteristic peaks at 2θ diffraction angles of 7.421, 7.738, 10.82, 13.701, 15.54, 18.941, 19.641, 21.299, 22.019, 23.041, 23.44, 23.96, 24.621, 26.6, 30.38, 34.399 and 38.319, wherein the 2θ error range is within ±0.2°. The dicarfentrazone-ethyl crystalline form D has good stability, and has a better control effect on broadleaf weeds and some grassy weeds when in a compound composition with other effective ingredients, the effect being significantly better than crystalline form A.
