[Korean Farmers' Newspaper Reporter Jo Young-kyu] #From control to transportation, agricultural robots are making strides. Pest control is a key agricultural task that determines the marketability of crops. The quality and quantity of the harvest depend on when, how, and how much pest control is done. To carry out pest control, one must carry a container filled with pesticides on their back and directly spray it with a sprayer. The weight of the container exceeds 20kg, making it impossible to work for long periods. Above all, direct pest control is directly linked to the safety of farmers. In the harsh reality of an aging rural population, something was needed to replace pest control. That something was a pesticide machine. Considering this reality, efforts have been made to mechanize pest control work.
