In this study, lambda-cyhalothrin (LC) used as a pesticide was microencapsulated with polyurethaneurea (PUU) at 55°C temperature for 180 min. Wall thickness and dimensions of the microcapsules, the effect of mixing speed on the capsule size, active substance release times of LC-PUU microencapsules under UV rays and alcohol/water medium, microencapsulation yields and the effect of microencapsulated active substance on the red spider on peppermint plant leaves (mentha piperita) were investigated. The microcapsule yield was found 77.4–85.5%, also capsule shell thickness was 512.3–724.5 nm. The highest release percentage of the microcapsules was found to be 35.00% at 20°C for 4 h under UV light. When the LC-PUU microcapsules applied to the peppermint plant leaves (mentha piperita) which contained a two-spotted red spider mites (tetranychus urticae), it remained active for 8 weeks and during this period no insect formation was observed on the peppermint leaves.

在这项研究中，将λ-氟氯氰菊酯（LC）用作农药，在55℃的温度下用聚氨酯脲（PUU）微囊化180分钟。微胶囊的壁厚和尺寸，混合速度对胶囊尺寸的影响，LC-PUU微胶囊在紫外线和酒精/水介质下的活性物质释放时间，微胶囊化率以及微胶囊活性物质对红蜘蛛的影响研究了薄荷植物的叶子（薄荷叶）。发现微胶囊的产率为77.4-85.5％，胶囊壳的厚度为512.3-724.5nm。发现微胶囊的最高释放百分比在20℃下在紫外线下4小时为35.00％。当LC-PUU微胶囊应用于薄荷植物叶子时（mentha piperita）它含有两个斑点的红蜘蛛（tetranychus urticae），它保持活性8周，在此期间，薄荷叶上未观察到昆虫形成。
