Pesticides are essential for protecting seeds and crops from pests but can harm health and the environment by contaminating soil, water, and non-target species, reducing biodiversity. Monitoring pesticide use and trade is key to assessing agricultural sustainability and market access. As awareness of these issues grows, farmers increasingly look for new ways to replace traditional practices but to maintain crop quality, and be sustainable. The key to achieving this balance lies in adopting more strategic and eco-friendly approaches to pest control.
Below, we will explore several practice for reducing pesticide use, ultimately fostering a more sustainable farming ecosystem.
Enhance Pest Monitoring
According to FAO, in 2022, total pesticide use in agriculture was 3.70 million tonnes (Mt) of active ingredients, marking a 4 percent increase in compare to 2021 and a doubling since 1990.
A crucial first step in reducing pesticide use is improving pest monitoring systems. Rather than relying on a routine schedule for pesticide application, farmers can implement Integrated Pest Management (IPM) practices, which focus on monitoring pest populations and only applying treatments when necessary. This approach allows for better-targeted applications, reducing overall pesticide use.
One effective way to monitor pests is through the use of pheromone traps, sticky traps, and field inspections. These methods help identify the presence of pests before they reach damaging levels, allowing for timely interventions. Farmers can also use pest forecasting models that incorporate weather data and past trends to predict outbreaks and plan appropriate responses.
Adopt Crop Rotation and Intercropping
Crop rotation and intercropping are powerful tools in pest management. These techniques help disrupt the life cycles of pests, making it harder for them to establish themselves year after year. Rotating crops with different nutrient requirements or pest resistances reduces the chances of pest populations building up in the soil.
Intercropping involves planting different crops together to create a more diverse ecosystem. Some crops may repel pests or confuse them with a range of scents and colors, while others can act as trap crops, drawing pests away from the primary crop. This method of pest control significantly lowers the need for pesticides by creating a more resilient cropping system.
Utilize Organic and Biopesticides
In cases where chemical intervention is necessary, organic and biopesticides offer a less harmful alternative to synthetic pesticides. Organic pesticides are derived from natural sources such as plants, minerals, or microbes. They break down more quickly than synthetic pesticides and are less likely to persist in the environment or harm non-target organisms.
Biopesticides, including microbial and botanical products, are designed to target specific pests while leaving beneficial insects unharmed. For instance, Bacillus thuringiensis (Bt) is a naturally occurring bacterium that targets caterpillars but is safe for other insects and mammals. Similarly, neem oil is a plant-based insecticide that disrupts the hormonal systems of pests, reducing their ability to feed and reproduce.
By incorporating organic and biopesticides into a pest management strategy, farmers can reduce their reliance on conventional chemicals while still effectively controlling pest populations.
Adopt Robotics and Automation
Recent advances in agricultural technology have led to the development of robotic systems that can precisely apply pesticides where they are needed. Robotics and automation save time and reduce the amount of pesticide required by targeting specific plants or pests rather than entire fields.
In vineyards, for example, automated robots equipped with sensors and AI can identify problem areas and deliver localized treatments, dramatically reducing pesticide use. This type of technology is particularly useful in high-value crops such as table grapes, where maintaining crop health without compromising quality is a priority.
Optimize Spraying Techniques
Optimizing spraying techniques is another key strategy for reducing pesticide use. Regular maintenance of spraying equipment, including calibration and nozzle replacement, ensures that pesticides are applied evenly and at the correct rate. This reduces the chances of over-application and helps prevent pesticide runoff into nearby ecosystems.
Farmers can also experiment with variable rate spraying (VRS) systems, which adjust the amount of pesticide applied based on factors such as crop type, pest density, and soil conditions. This technique maximizes efficiency by applying the right amount of pesticide exactly where it’s needed, reducing overall consumption.
Robs4Crops: Reducing Pesticide Use with Sustainable Agriculture
Robs4Crops is an EU-funded initiative aimed at transforming European agriculture through robotics and automation. The goal is to reduce labor intensity and chemical input in farming, using cutting-edge solutions that can address the challenges faced by traditional agricultural systems. The project focuses on creating autonomous systems for precision agriculture, including pesticide spraying.. Two of the projet pilots, LSP2 – Table Grape Spraying and LSP3 – Apple Orchard Spraying, illustrate how advanced systems can optimize pesticide application, reducing environmental impact and improving crop management.
Combining Precision Agriculture and Robotics
Both LSP2 and LSP3 focus on using automated, sensor-driven systems to manage pesticide spraying more effectively. These pilots rely on retro-fitted tractors equipped with smart sprayers and advanced AI-based decision-making tools. This combination enables the accurate detection of specific areas requiring treatment, reducing pesticide overuse and ensuring only affected regions are sprayed.
LSP2 addresses the challenges of pesticide spraying in vineyards, particularly in table grape production. Traditionally, pesticide application in grapevines tends to be excessive, resulting in chemical overuse and environmental damage. LSP2’s robotic system incorporates sensors that detect the real-time needs of the vines and adjust spraying patterns accordingly, ensuring that pesticides are only used where and when necessary.
Similarly, LSP3 focuses on improving the spraying process in apple orchards. Apple trees often require significant pesticide use to combat fungal diseases, but the system in LSP3 integrates robotic sprayers and real-time data to determine tree health and disease risks. This approach tailors pesticide application to the specific conditions of the orchard, resulting in a significant reduction in pesticide use and an overall more efficient operation.
Projects like Robs4Crops are in charge of demonstrating how autonomous systems can create a more sustainable and efficient agricultural sector. By adopting these advanced technologies, farmers can reduce their environmental footprint, enhance profitability, and improve the long-term health of their crops and ecosystems.
