ZAPPER is a contact product, with a special mode of action.
ZAPPER is a complex of entomopathogenic fungi, an endophytic association,
with a similar mode of action. Fungi colonize and grow naturally in the soil, where they can remain for long periods even in the absence of targets, and act as a parasite.
When the microscopic spores of the fungus come into contact with the body of an insect host, they germinate, penetrate the cuticle and grow inside until they reach the hemolymph (blood), feed on the nutrients in the insect’s body producing toxins, killing the insect in a few days (maximum 3 -5 days).
After a mold appears on the dead bug, the mycelium grows outward, and produces new spores that can infect new pests. These spores in Beauveria bassiana are white in color, hence the disease is called white muscardina, and in Metarhizium anisopliae the spores acquire a green color, and thus the disease is called green muscardina. The death of pests occurs in 3-5 days after treatment.
