management. Easy to apply as a wettable powder, it can be seamlessly incorporated into existing agricultural practices.



Mode of Action

The mode of action of Verticillium chlamydosporium involves its role as an entomopathogenic (insect-killing) fungus with a unique life cycle and infection strategy. When used as a bio-pesticide, its primary target is nematodes, which are harmful to crops. Its mode of action involves-

  • Colonization: Verticillium chlamydosporium initially colonizes the soil and the root zone of plants where the target nematodes reside. The fungus forms a symbiotic relationship with the plant, known as an endophytic relationship, by entering the plant’s tissues without causing any harm.
  • Infection: Once inside the plant, the fungus grows and multiplies, producing specialized structures called chlamydospores. These chlamydospores are the infectious stage of the fungus and are responsible for parasitizing nematodes.
  • Nematode Parasitism: When nematodes come into contact with the chlamydospores, the fungus attaches to their cuticle (outer covering). The chlamydospores then germinate, producing hyphae that penetrate the nematode’s body, gaining entry to the nematode’s internal tissues.
  • Nematode Death: Inside the nematode, the hyphae proliferate and grow, causing the nematode to become weakened and eventually killed. The fungus utilizes the nematode’s tissues as a nutrient source to support its own growth and development.
  • Reproduction and Spread: After the nematode is killed, the fungus completes its life cycle and produces new chlamydospores, ready to infect other nematodes in the soil, continuing the biocontrol process.
