Crystalline form A of 1,5-dimethyl-6-thioxo-3-(2,2,7-trifluoro-3-oxo-4-(prop-2-ynyl)-3,4-dihydro-2h-benzo[b][1,4]oxazin-6-yl)-1,3,5-triazinane-2,4-dione

摘要

The present invention relates to a novel crystalline form A of 1,5-dimethyl-6-thioxo-3-(2,2,7-trifluoro-3-oxo-4-(prop-2-ynyl)-3,4- dihydro-2H-benzo[b][1,4]oxazin-6-yl)-1,3,5-triazinane-2,4-dione. The invention also relates to a process for the production of this crystalline form and formulations for plant protection which contains the novel crystalline form of 1,5-dimethyl-6-thioxo-3-(2,2,7-trifluoro-3- oxo-4-(prop-2-ynyl)-3,4-dihydro-2H-benzo[b][1,4]oxazin-6-yl)-1,3,5- triazinane-2,4-dione.
