我省油菜害虫繁多,尤以苗期、蕾苔期、结荚期为最,各期主要害虫不同,但蚜虫贯穿整个生育期的始终,时间长,为害烈。目前生产上采用一般农药防治4、5次还不能彻底解决问题,不但用工量大,而且封行后进地困难,无法防治。1980—81年,我们试用呋喃丹进行防治,防次大减,防效显著。供试药剂为3％呋喃丹颗粒剂(以下简称呋喃丹),此药为广谱性内吸杀虫剂,具触杀、胃毒作用。国内外用于稻、棉、豆、烟等,但对防治油菜害虫未见报道,现将试验中三期结果简报于后。播期试验田间试验分设两处:一在武功水地甘兰型油菜区;一在永寿旱地白菜型油菜区。前作均为小麦,栽培管理与品种和当地生产要 Pear rape in our province many, especially in the seedling stage, buds moss period, the most pod stage, the main pests in different stages, but the aphids throughout the growing period has always been a long time, as a strong fierce. At present, the production of pesticides using general control 4,5 times can not completely solve the problem, not only the large amount of labor, but also difficult to seal line after the inability to prevent and cure. In 1980-81, we tried carbofuran for prevention and treatment, preventing major degeneration and preventing disease. The test agent is 3% carbofuran granules (hereinafter referred to as carbofuran), this drug is a broad-spectrum systemic insecticide, with contact kill, stomach poisoning effect. At home and abroad for rice, cotton, beans, tobacco, but no reports of prevention and treatment of rape pests, the trial is now the third phase of the results briefed later. Sowing date Field trials are divided into two parts: one in Kashgar water Ganlan type rapeseed area; one in the Evergreen dry cabbage rape area. Before the crop are wheat, cultivation management and variety and local production to be
