摘要

The present invention, 1,5-dimethyl-6-thioxo-3- (2,2,7- trifluoro-3-oxo-4- (prop-2-ynyl) -3,4-dihydro -2H- benzo [ b] [1,4] relates to a novel crystalline form A of oxazine-6-yl) -1,3,5 Toriajinan-2,4-dione. The invention also, the manufacturing method of the crystalline forms and 1,5-dimethyl-6-thioxo-3- (2,2,7- trifluoro-3-oxo-4- (prop-2-ynyl) -3, 4-dihydro -2H- benzo [b] on Plant protection formulation comprising a [1,4] oxazin-6-yl) novel crystalline form of the 1,3,5 Toriajinan-2,4-dione. [Formula 1] .BACKGROUND
