A Comparative Analysis of Drone and Manual Granular Insecticide Delivery Impact on Paddy Soil Microbiota

Abstract

Aims: Assessment of the impact of granular insecticide application through manual and drone-based methods on soil microbial communities in rice ecosystems. Study Design: Randomized Block Design. Place and Duration of Study: Main Farm, Agricultural Research Institute, Professor Jayashankar Telangana Agricultural University (PJTAU), Rajendranagar, Hyderabad during kharif, 2024 (wet season. July-November). Methodology: A field experiment conducted during kharif 2024, evaluated the impact of granular insecticides applied using drone vis a vis manual method on the soil microbial communities in rice variety of RNR 15048. The treatments viz., carbofuran 3 CG (25 kg/ha), cartap hydrochloride 4G (20 kg/ha), chlorantraniliprole 0.4G (10 kg/ha), chlorantraniliprole 0.5% + thiamethoxam 1.0% GR (6 kg/ha), flubendiamide 0.70 GR (12.5 kg/ha) were applied twice at an interval of at 15-days, commencing 30 days post-transplantation. The study focused particularly on assessing the populations of key microbial groups, including bacteria, actinomycetes and fungi. Results: These findings revealed that among all the treatments, chlorantraniliprole 0.5% + thiamethoxam 1.0% GR (T5 D and T10 M), carbofuran 3 CG (T1 D and T6 M) and chlorantraniliprole 0.4G (T3 D and T8 M) applied via drone or manually, exhibited relatively higher microbial populations than the other treatments, which suggests that the mode of application, drone or manual, did not adversely affect the soil microbial communities. Conclusion: The findings indicate that drone based granular application does not hinder the soil microbial populations. Further, it enhances operational efficiency, reduces labor requirements and enables effective pest management.
