Drip application of insecticides has been used for controlling crop pests, but the application doses are usually higher than those used for foliar spray. Arbuscular mycorrhizal fungi (AMF) have been reported to improve root absorption of nutrients from soil, which may also enhance the uptake of drip‐applied insecticides, reducing application doses. In this study, greenhouse and field experiments were carried out to determine if AMF could colonize cotton roots, if the colonization could enhance the absorption of drip‐applied flonicamid, and if the enhanced uptake could reduce flonicamid application dose, while maintaining control efficacy against cotton aphid.

丛枝菌根真菌可增强对滴灌氟尼丁的吸收，并改善对棉蚜的控制。

滴灌杀虫剂已被用于防治农作物害虫，但施用剂量通常高于叶面喷洒的剂量。据报道，丛枝菌根真菌（AMF）可以改善土壤中养分的根吸收，这也可能会增加滴灌杀虫剂的吸收，从而减少施用剂量。在这项研究中，进行了温室和田间试验，以确定AMF是否可以在棉花根部定植，定植是否可以增加滴灌氟尼康的吸收，以及增强吸收是否可以减少氟尼康的施用量，同时保持对棉花的控制效力蚜。
