A HAIDRA  pesticide spray machine, also known as an agricultural sprayer, is a piece of equipment designed to uniformly apply liquid solutions—such as pesticides, herbicides, fungicides, and liquid fertilizers—to crops, plants, or soil. Their main function is to protect crops from pests, diseases, and weeds, and to ensure nutrient uptake, which ultimately contributes to improved crop health and yield.

The complexity and size of these machines vary significantly, from small, hand-held units to large, self-propelled, or drone-based system
