Final answer:
In general pest control, the commonly used sprayers include handheld, backpack, and truck-mounted sprayers; each varies in capacity and coverage, suitable for different scales of application.
Step-by-step explanation:
Three commonly used sprayers in general pest control are:
- Handheld sprayers: These are typically used for small areas or spot treatment. Easy to carry and operate, handheld sprayers offer portability and convenience for residential or minimal pest control needs.
- Backpack sprayers: Similar to handheld sprayers but with a larger capacity, these allow technicians to carry more pesticide and cover larger areas without the need for constant refilling. They are carried on the back and provide greater efficiency for medium-sized applications.
- Truck-mounted sprayers: For large scale or commercial use, these sprayers are mounted on vehicles. Offering the largest capacity and longest range, truck-mounted sprayers are used for extensive pest control projects such as agricultural fields or urban landscaping.
Pesticides, including herbicides, insecticides, and fungicides, are substances used to control various pests. While herbicides are the most common, accounting for approximately 80% of all pesticide use, selecting the right sprayer is crucial to effectively applying these chemicals.
