When planning to use a drone for drug eradication efforts, there are several key considerations beyond simply operating the drone itself. First and foremost, it’s crucial to ensure the cleanliness of the medicine container before any operation. If the container isn’t properly cleaned, especially if there are visible residues or “drug scales,†it suggests a lack of attention to detail and professionalism. To address this, soak the container in water mixed with a detergent solution at a ratio of one-thousandth for half an hour, then shake it for a few minutes before rinsing thoroughly. Follow this by washing the container with water containing 10% ethanol to eliminate any organic solvents and reduce foam formation.
Secondly, always verify the nozzle atomization efficiency before starting operations. Ensure there are no blockages caused by impurities that could hinder performance. Thirdly, given the concentrated nature of drone-based pesticide applications compared to traditional methods, it’s essential to confirm the compatibility of all substances being mixed. Diluting these substances twentyfold and testing their interactions can help identify potential issues like agglomeration, heat generation, or gas release.
It's advisable to avoid using pesticides labeled as suspensions or gel suspensions due to their high viscosity and potential for clogging nozzles. These often contain additives like xanthan gum or modified starch, which complicate atomization and risk nozzle blockage.
The sequence of adding ingredients is equally critical. Begin by filling the container halfway with clean water. Next, add any acidic water-soluble fertilizers first to purify the water quality. Then, introduce wettable powders, followed by emulsifiable pesticide concentrates. A silicone synergist should follow, as it enhances the mixture's effectiveness. Ketamine can be added next, followed by acetic acid if needed, typically at a rate of 10 grams per kilogram of diluent. Finally, top off the container with water and mix thoroughly.
Acidic water-soluble fertilizers not only purify water but also enhance the efficacy of subsequent ingredients. Acetic acid protects pesticides from degradation while promoting mild crop growth stimulation, though its usage should be minimal to maximize its benefits.
After completing a mission, immediate cleaning of the drug application container is vital to prevent phytotoxicity and prolong equipment lifespan. Even if multiple applications are done on the same day, the container and nozzle should be cleaned daily using diluted ethanol. Additionally, employing an atomizer that generates negatively charged ions can significantly enhance spraying efficiency. Plants naturally carry positive charges on their surfaces, so the attraction between positive and negative charges ensures better adhesion of the liquid to crops, improving efficacy, reducing pesticide waste, and minimizing drift-induced phytotoxicity.
In conclusion, proper preparation, careful mixing, and post-operation maintenance are essential for maximizing the effectiveness of drone-based drug eradication efforts.
