Question: 1 / 605

Which of the following is not one of the four main groups of pests?

Pathogens

Pathogens are not considered a group of pests because they are not organisms that cause direct harm to crops or plants. Pathogens are microorganisms like bacteria, viruses, and fungi that cause diseases in plants. The main groups of pests are vertebrates, invertebrates, and weeds, which are all living organisms that can damage or compete with plants for resources. Vertebrates include animals like birds, rodents, and mammals, while invertebrates include insects and other small creatures. Weeds, on the other hand, are unwanted plants that can disrupt crop growth.
