Mode of Action
Unique oil coated , UV protected spores effective against various stages of the pest life cycle. The formulation prevents the fungal spores from drying out and becoming deactivated under field conditions that are less than favourable. It also enhances penetration and infection of the caterpillar.
Metarhizium rileyi spores can either penetrate through the cuticle or enter the larvae through ingestion during feeding. Once inside the larvae, the fungus grows and multiplies, eventually killing the larvae by internal tissue destruction. Between 2-4 days after the initial infection the larva stops feeding and dies 5-7 days later. Once the larva has died the fungus sporulates, therefore having the ability to remain in the environment and re-infect the next generation of pests.
