Abstract: The present invention relates to a novel crystalline form of 1-(1,2-dimethylpropyl)-N-ethyl-5-methyl-N-pyridazin-4-yl-pyrazole-4-carboxamide recently assigned the common name dimpropyridaz. The invention also relates to the use of the crystalline form B for combating invertebrate pests and to formulations for plant protection which contain the crystalline form B of 1-(1,2-dimethylpropyl)-N-ethyl-5-methyl-N-pyridazin-4-yl-pyrazole-4-carboxamide. The crystalline form B according to the present invention can be identified by powder X-ray diffractometry on the basis of its powder X-ray diffraction diagram, hereinafter also termed powder X-ray diffraction pattern or PXRD pattern, of the polymorph form B recorded using Cu—Kα radiation (1.54178 Å) at 25° C. displays the 3 following reflections, quoted as 2θ values: 20.69±0.10°, 24.15±0.10° and 30.52±0.10°. In addition to these 3 reflections, the polymorph B of the present invention may display in such a PXRD pattern one or more, in particular at least 2, often at least 4, in particular at least 6 or at least 8 reflections and especially all of the reflections quoted hereinafter as 2θ values: 7.99±0.10°, 10.07±0.10°, 12.38±0.10°, 15.31±0.10°, 15.97±0.10°, 16.50±0.10°, 18.03±0.10°, 19.29±0.10°, 20.22±0.0.10°, 20.96±0.10°, 23.40±0.10°, 23.70±0.10°, 26.09±0.10°, 27.26±0.10° and 32.91±0.10°.
