Final answer:
The two types of certified applicators are private and commercial. Private applicators apply pesticides on their own or rented land for agricultural purposes, while commercial applicators are professionals offering pest control services.
Step-by-step explanation:
The two types of certified applicators are private and commercial. A private applicator is someone who applies pesticides to their land or rented land to produce any agricultural commodity. This typically relates to farmers or ranchers controlling pests on their crops or livestock. On the other hand, a commercial applicator is a professional who applies pesticides as part of a service they provide for which they are paid. This can include individuals who work for pest control companies or businesses providing landscaping and pest control services.
Both types of applicators need to undergo proper training and certification to ensure they are applying pesticides safely and effectively, minimizing environmental impact and adhering to legal regulations. These certifications are often regulated by governmental agencies that focus on environmental protection and agricultural services.
