Emrald Aayushi is an entamopathogenic fungus commonly called as White muscardine. Emrald Aayushi helps in protecting the stem and fruits from being attacked by insects. The entomopathogen invades the insect body. Fungal conidia attach to the insect cuticle and, after germination, the hyphae penetrate the cuticle and proliferate in the insect's body. High humidity or free water is essential for conidial germination and the infection establishes itself between 24 and 48 hours. The infected insect may live for three to five days after hyphal penetration and die slowly. The conidiophores bearing conidia are produced on cadaver. Emrald Aayushi is insect specific.
Emrald Dakshan contains the insect pathogenic fungus Metarhizium anisopliae which is a widely distributed soil- inhabiting fungus.
When sprayed on the plant, it generally enters into the insects through spiracles and pores in the sense organs and produces a lateral extension of hyphae. When the internal contents have been consumed, the fungus breaks through the cuticle and sporulates, there by killing the insect. The pests are controlled within 3 – 5 days.
