Abstract
Drones (UAV) are highly beneficial tools for the agriculture due to their versatility and speed, ideal for ultra-low volume interventions.
One of the most demanding tasks in citriculture is the spray of phytosanitary in a quickly and timely manner.
The aim of the present study was to evaluate the use of drones for insecticide sprays to control the citrus leafminer.
The experiment took place in Burruyacú, Tucumán, Argentina, in 5 years ‘Frost Nucellar Lisbon’ lemon/‘Flying Dragon’ combination, planted at 5.25×2.75 m.
The experimental design was randomized blocks with three repetitions per treatment, each consisting of five rows of which the central row was evaluated.
The treatments were: T1: control; T2: drone spray parallel to the rows; T3: drone spray perpendicular to the rows and T4: spray with low volume hydropneumatic sprayer.
The percentage of live and dead citrus leafminer larvae was assessed at three different times: pre-application, seven days after application (7 DAA) and 14 DAA. The active ingredients, dose and volume used, are shown below: T2 and T3: 200 mL Abamectin 1.8 + 3 L of mineral oil in 10 L of tank mix, spray volume of 0.014 L tree‑1, and T4: 200 mL Abamectin 1.8 + 2 L of mineral oil in 1000 L of tank mix, spray volume of 0.5 L tree‑1. The results of the percentage of leafminer larvae alive at 7 DAA were for T1 58.13%, T2 4%, T3 18.57% and T4 6.13%. T2 and T4 did not differ statistically, both differing from T1 and T3. Regarding the results, drone application treatment parallel to the plantation rows presents the same control of live leafminer larvae as the conventional terrestrial treatment.
Drone application is a tool to be considered in the management of citrus leafminer.
