The present invention relates to the technical field of herbicide crystallization process, particularly to Crystalline form C of shuangzuocaotong, and a preparation method therefor and use thereof. The Crystalline form C of shuangzuocaotong has an X-ray powder diffraction pattern having characteristic absorption peaks at the following 2 positions: 10.159, 10.658, 13.318, 14.579, 16.096, 18.061, 19.322, 19.68, 20.04, 20.659, 21.281, 23, 24.16, 24.619, 26.101, 26.74, 30.359, 31.018, 32.378, 35.398 and 38.26 degrees, wherein 2 has an error range within 0.2. The Crystalline form C of shuangzuocaotong has good stability, and its compounded composition with additional active ingredient(s) has a good control effect to broadleaf weeds and some gramineous weeds in wheat, significantly better than that of Crystalline form A of shuangzuocaotong.

This invention discloses a type of 1,8-bis(Schiff base)-p-menthane derivatives as well as their preparation method and applications. The reaction of 1,8-diamino-p-menthane with a substituted benzaldehyde was carried out in a polar organic solvent at 0 C.-75 C. for 1-48 h. After the completion of the reaction, part of the solvent was distilled off to perform recrystallization to get a 1,8-bis(Schiff base)-p-menthane derivative, whose pre-emergence herbicidal activity against ryegrass was determined by using the Petri dish seed germination method. The 1,8-bis(Schiff base)-p-menthane derivatives, obtained with this method in high yield and mild reaction conditions, have a good inhibitory effect on the growth of annual ryegrass, and low toxicity.
