| 摘 要： | 为明确含不同成膜剂的噻虫啉种衣剂处理玉米种子后在土壤和植株中的持效性及其对刺吸式害虫的防治效果,选择3种不同成膜剂加工成的噻虫啉悬浮种衣剂以400 g a.i.100 kg^-1种子浓度包衣处理,分别于室内和田间条件下测定其对玉米出苗率、生长量和生理生化等方面的影响,及噻虫啉在玉米叶片和土壤中的持效期,并评价其对刺吸式害虫的防治效果。结果表明,ZY904-3和ZY904-5成膜剂的噻虫啉种衣剂处理对玉米出苗没有影响,3种成膜剂的噻虫啉拌种对玉米生长量和生理生化活性均有不同程度促进,玉米叶片和土壤中的噻虫啉持效期较未加成膜剂有一定延长,ZY904-1、ZY904-3和ZY904-5处理的噻虫啉悬浮种衣剂(FS)在叶片和土壤中持效期分别延长了20~40 d、20~30 d和10~20 d。3种成膜剂处理可有效防治玉米刺吸式害虫,ZY904-1和ZY904-3成膜剂的噻虫啉种衣剂处理对玉米刺吸式害虫数量有很好的控制作用,分别于播种80 d(室内)和60 d(田间)后防效仍达50%以上,但ZY904-1成膜剂的噻虫啉种衣剂推迟出苗时间。综合各个方面,ZY904-3成膜剂的噻虫啉种衣剂拌种效果最好。

| Abstract: | To definite the persistence of thiacloprid seed coating with different film-forming agents in soil and plants and the efficacy in controling piercing-sucking insects, we tested the effects of the thiacloprid FS, with three different film-forming agents at a concentration of 400 g a.i. 100 kg -1, on the emergence rate, growth, physiological and biochemical characteristics of maize at laboratory and in the field respectively, and evaluated controlling effect on piercing-sucking insects by high performance liquid chromatography-mass spectrometry (HPLC-MS/MS). The ZY904-3 and ZY904-5 film-forming agent treatments had no influence on emergence rate of maize. The seedling growth and activities in physiology and biochemistry were promoted to various degrees by thiacloprid seed dressing with three different film-forming agents. Compared with no film-forming agent treatments, the persistent periods of ZY904-1, ZY904-3, and ZY904-5 treatments were extended by 20-40 days, 20-30 days, and 10-20 days in leaves of maize and in the soil respectively. The maize piercing-sucking insects were controlled significantly by three film-forming agent treatments. ZY904-1 and ZY904-3 treatments had good control effects on the amount of piercing-sucking insects in the growth stage of maize which coat still over 50% at 80 d (laboratory test) and 60 d (field test) after sowing, respectively. However, ZY904-1 treatment delayed the emergence of seeds. Taking all factors as a whole, ZY904-3 film-forming agent has the best seed dressing effect. |
