Abstract

Foliar application of cyantraniliprole @ 60 g a.i ha^− 1 was found most effective and statistically superior to standard checks imidacloprid and thiamethoxam in reducing Diaphorina citri population in kinnow mandarin upto 14 days of treatment. Thus the nature and amounts of active metabolites of cyantraniliprole used in kinnow are set to ensure the safety of the consumers and environment. Hence residue of cyantraniliprole at effective dose i.e. 60 g a.i ha^− 1 and double of effective dose i.e. 120 g a.i ha^− 1. using 1000 L of water was estimated from kinnow fruits and soil. The average initial deposit of cyantraniliprole in kinnow fruits were 0.254 and 0.415 mg kg^− 1 which dissipated to the extent of 95.28 and 95.15% in the respective doses after 10 days and to below detectable limits after 15 days of spray. The residue of cyantraniliprole in soil was found below detectable limits after 10 days of spray. It is concluded that cyantraniliprole can be used in D. citri management programme in kinnow mandarin and the pre-harvest interval recommended for safe consumption of kinnow fruits was observed to be 15 days.

印度旁遮普邦亚热带条件下金诺柑橘中氰虫酰胺的生物功效和持久性

摘要

叶面喷施氰虫酰胺 @ 60 g ai ha ^{− 1}被发现在减少金诺柑橘中柑橘木虱数量方面最有效，并且在统计上优于标准检查吡虫啉和噻虫嗪，最多治疗 14 天。因此，设置了 kinnow 中使用的氰虫酰胺活性代谢物的性质和含量，以确保消费者和环境的安全。因此，有效剂量（即60 g ai ha ^-1）和双倍有效剂量（即120 g ai ha ^-1）的氰虫酰胺残留。估计使用 kinnow 水果和土壤中的 1000 升水。氰虫酰胺在金诺果中的平均初始沉积量为 0.254 和 0.415 mg kg ^{- 1，10}天后消散至各自剂量的 95.28% 和 95.15%，喷雾 15 天后消散至可检测限度以下。喷洒 10 天后，发现土壤中氰虫酰胺的残留量低于可检测限度。结论是氰虫酰胺可用于金诺柑橘的柑橘蝇管理计划，并且建议安全食用金诺果的采收前间隔为 15 天。
