甜菜是我局的主栽作物之一,苗期危害甜菜的主要害虫是跳甲,被害甜菜轻时保苗率下降,子叶皱缩、瘦小,一般较健叶短0.2～0.3cm;重时导致毁种。过去用菊脂类药剂或乙六粉等防治,往往因为防治不及时或其它原因效果不理想。35％呋喃丹种衣剂除含有杀虫剂外,还含有生长素类药物成分,既可以防虫又可以促进甜菜生长发育,1991年我局大面积应用后取得了较理想的效果,块根产量增加8.8％。35％呋喃丹种衣剂主要是应用于种子处理,以培育毒苗,用量为种子重量的2.5％,拌种时,水、药比以7:1稀释,拌种在播种前一天进行,拌好后的种子堆起盖好,晚间可以摊开阴干,播前灌袋。
Beet is one of the main crops of our bureau. The main pest that endangers beet in seedling stage is the jumping beetle. When the beet is light, the seedling protection rate is decreased while the cotyledon is shrunk and thinner, which is 0.2-0.3cm shorter than that of healthy leaves. Species. In the past with chrysanthemum agents or B6 powder prevention and control, often because of prevention or other reasons not timely results are not satisfactory. In addition to insecticides, 35% of carbofuran seed coating also contains auxin ingredients, which can both prevent pests and promote the growth and development of sugar beet. In 1991, after a large area application, I obtained satisfactory results and increased root tuber yield 8.8%. 35% carbofuran seed coating is mainly used in seed treatment to cultivate the vaccine, the amount of seed weight 2.5%, seed dressing, water, medicine than 7: 1 dilution, seed dressing in the day before sowing, mix After a good pile of seeds piled up at night can be spread dry, sowing before sowing.
