What is a "pesticide sprayer"?

A pesticide sprayer is a tool used to apply chemicals, known as pesticides, to plants or soil to control pests, such as insects, fungi, or weeds. It typically consists of a tank to hold the pesticide, a nozzle for spraying, and a handle for carrying and directing the spray. Pesticide sprayers can be manual, operated by pumping or squeezing, or powered by batteries or engines for larger tasks. They are important for protecting crops, plants, and gardens from harmful pests, but must be used carefully to avoid harming beneficial insects or the environment.
