Chemical applicators are tools or devices used to apply chemicals, such as pesticides, herbicides, or fertilizers, to crops, gardens, or other areas. They come in various forms, including sprayers, spreaders, and injectors, and are designed to ensure even and efficient distribution of the chemicals. Proper use of chemical applicators helps protect plants and improve agricultural productivity. These applicators can be manual or powered, depending on the scale of the application. For example, handheld sprayers are suitable for small gardens, while tractor-mounted sprayers are used for larger fields. Understanding how to use these tools safely is essential for effective chemical management.
