| 为探究植物源喷雾助剂在化学防治中的减药增效作用，测定比较3种植物源喷雾助剂（植物源甘油酯、光合高脂膜和橘康）和矿物油及混配螺螨酯后的物理性能，且选择混配物理性能最好的植物源喷雾助剂与矿物油对柑橘红蜘蛛Panonychus citri（McGregor）田间防治效果进行比较评价。结果表明，4种助剂与螺螨酯混配后均能显著降低药液在柑橘叶片上的接触角、提高固体表面能和黏附性能，植物源甘油酯和光合高脂膜提高螺螨酯药液物理性能均显著优于矿物油，尤其植物源甘油酯，其降低接触角41.29°、增加固体表面能19.82 MJ/m2、增加黏附性能49.2 J/m2；橘康降低药液接触角也优于矿物油。植物源甘油酯和矿物油作为助剂推荐使用浓度（300倍）与螺螨酯推荐使用浓度减量50%混配，对柑橘红蜘蛛15 d内的防治效果与螺螨酯推荐使用浓度无显著差异，说明两种助剂不仅使螺螨酯减药增效，且可减量50%；两种助剂单独喷施防治柑橘红蜘蛛，植物源甘油酯15 d的防效可达63.2%，远高于矿物油。综上所述，3种植物源助剂在提高螺螨酯物理性能方面优于矿物油，而植物源甘油酯胜过另外两种植物源助剂，且单独使用植物源甘油酯对柑橘红蜘蛛也有较好的防效。研究结果为化学防治的减药增效提供了参考。 |

| In order to explore the effect of plant-derived spray additives in chemical control of reducing the amount and increasing the efficiency, the physical properties of three plant-derived spray additives (plant-derived glycerides, photosynthetic high-lipid membrane and Jukang high-lipid membrane) and mineral oil and their respective mixture with spirodiclofen were compared, and the field control effect of the plant-derived spray additives with the best physical properties and mineral oil against Panonychus citri (McGregor) were evaluated. The results showed that all of the four additives could significantly reduce the contact angle and improve the solid surface energy and adhesion properties of the spirodiclofen solution on citrus leaves. And the physical properties of the solution improved by plant-derived glycerides and photosynthetic high-lipid films were significantly better than those of mineral oil, especially the plant-derived glycerides, where the contact angle was reduced by 41.29°, the solid surface energy increased by 19.82 MJ/m2, and the adhesion properties increased by 49.2 J/m2. Jukang high-lipid membrane was better than mineral oil in terms of reducing the contact angle of chemical liquid. The recommended concentration (300 X) as additives of plant-derived glycerides and mineral oil were mixed with the reduction of 50% of recommended concentration of spirodiclofen against citrus red spider, respectively, and there was no significant difference in the control effect within 15 days, indicating that the two additives not only increased the control effect of spirodiclofen with reduced dosage, but also it could achieve the same effect with a 50% reduction in usage. However, two additives were applied separately to control citrus red spider, the control effect of 15-day of plant-derived glycerides was 63.2%, which was much higher than that of mineral oil. In summary, the three plant-derived spray additives were superior to mineral oil in improving the physical properties of spirodiclofen, and plant-derived glycerides outperformed the other two plant-derived additives, besides and the use of plant-derived glyceride alone also had a better control effect on citrus red spider. The results of this study provided a reference for the reducing the amount and increasing the efficiency of chemical control. |
