为了大面积推广应用35%多福克大豆超微粉种衣剂,2014-2015年,在黑龙江省大豆主产区,对35%多福克大豆超微粉种衣剂进行了田间试验。结果表明:超微粉种衣剂1∶300和1∶200拌种处理,对大豆病虫害防效显著,病虫害流行区域的增产效果明显。超微粉种衣剂1∶300和1∶200处理,对根腐病的防效分别为76.9%、80.2%;对胞囊线虫防效分别为77.1%、83.3%;对蛴螬的防效分别为81.7%、87%,对根潜蝇的防效分别为93.2%、95.7%。
In order to popularize and apply 35% multi-gram soybean ultrafine seed coating agent on a large scale, a field experiment was conducted on 35% multifogan soybean seed dressing in 2014-2015 in the main soybean producing area of Heilongjiang Province. The results showed that the seed dressing of superfine powder 1: 300 and 1: 200 could significantly increase the yield of pests and diseases in the pest and disease control areas. The control effect on the root rot was 76.9% and 80.2% respectively when treated with 1: 300 and 1: 200 micropowders. The control effects on cyst nematode were 77.1% and 83.3%, respectively. The control effects on the galls were 81.7% and 87%, respectively. The control effects on root-dive flies were 93.2% and 95.7% respectively.
