新型柴油乳剂的研制及防治红圆蚧的效果

Preparation of Diesel Oil Emulsion and Its Effectiveness on Controling the Red Scale

研制了含油量为９０％的柴油乳油和含油量为８５％的柴油浓乳剂２种剂型，其乳化性能好，稳定性高．药效试验结果表明，９０％柴油乳油５０倍液对四季柚红圆蚧（ＡｏｎｉｄｉｅｌｌａａｕｒａｎｔｉｉＭａｓｋ．）的大田防效为８４．２％，８５％柴油浓乳剂５０倍液防效为６６．７％．该柴油乳剂制造工艺简单，成本较低，值得生产上推广使用．

Two diesel oil emulsions are prepared. One contained 90% of diesel oil and another 85%. Both of them are well emulsified and highly stabilized. Application of these two emulsions to control red scale in the field shows that the mortality of the red scale are high.
