摘要
我国农药乳油制剂酸碱性技术指标以往多用酸度表示。高效氯氰菊酯、溴氰菊酯、氯氟氰菊酯等乳油不同酸度或pH值的制剂试样热贮试验表明，对介质酸碱性较敏感的有效成分乳油制剂，质量控制应采用严格的pH值范围作为技术指标。
We usually use the acidic or basic content as the acidity or basicityspecification of pesticide emulsifiable concentrate. However, for the EC ofdeltamethrin and lambda-cyhalothrin, we suggest to use hydrogen ion concen-tration (pH) to express their acidity or basicity, because those pyrethroids arevery sensitive to acid and base. The heat stability test under deferent acidity orpH proved the fact.
