The invention relates to new pyrazoline derivatives having insecticidal activity; the new compounds can be represented by the general formula
wherein R is an alkoxycarbonyl group having 2 to 6 carbon atoms,
X and Y are equal or different and represent hydrogen atoms or halogen atoms,
and n is 2, 3 or 4.
After having been processed to compositions, the compounds may be used for the control of insects in a dosage from 0.01 to 1 kg of active substance per hectare.
本发明涉及具有杀虫活性的新
吡唑啉衍
生物;新化合物可用通式表示,其中 R 是具有 2 至 6 个碳原子的烷氧羰基,X 和 Y 相同或不同,代表氢原子或卤素原子,n 是 2、3 或 4。
