Abstract:
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.
Abstract:
N-(tetrazol-5-yl)- and N-(triazol-5-yl)hetarylcarboxamides of formula I and their use as herbicides. The invention relates to N-(tetrazol-5-yl)- and N-(triazol-5-yl)hetarylcarboxamides of formula I and their use as herbicides. In said formula I, B represents N or CH, whereas X1 is N or CR1, X2 is N or CR2, X3 is N or CR3 and X4 is N or CR4; provided that a least one of X1, X3 and X4 is N; R, R1, R2, R3, R4 and R5 represent groups such as hydrogen, halogen or organic groups such as alkyl or phenyl.
