Hybrids blockchain, AI, IoT, and 6G technology integration: It is a transformatory approach towards pesticide use in agriculture towards its optimization and protection of human life expectancy. In the research paper, I provide an all-inclusive framework. Using IoT sensors deployed in agriculture fields and real- time data collection, it monitors the soil moisture, temperature, and pesticide levels in the environment. The system considers hybrid blockchain technology, which enables secure and tamper-proof data management with transparency to comply with agrarian regulations. The hybrid IPFS is part of the storage solution for large sets of data, allowing efficiency in the database management system and scalability to manage the challenges in data management pertaining to agriculture. Advanced AI models-SVM, Random Forests, and Decision Trees analyze the data to predict the optimal pesticide application thresholds. The 6G technology will implement ultra-fast communication, making instant decisions as well as instant automated action taken by smart contracts. It is a new framework aimed at supporting crop health and production, but more notably diminishing the exposure of hazardous pesticides toward humans and sustaining improved public health outcomes. The research will present solutions to the challenges in the management of pesticides to prove that new technologies can address issues of sustainable agricultural practices with minimal harm to human life.
