Tierra Overseas is manufacturer and exporter of high quality Ampelomyces quisqualis in India.
Mode of Action
Once the product is applied, after gaining moisture- conidia are discharged from the ripe pycnidia and are dispersed by rain-splash to mildew colonies. For infection, free water is required, while infection is favoured by warm temperatures (20-30° C). If conditions are favourable, infection can occur in less than 24 hours. The mycoparasite directly penetrates the walls of hyphae, conidiophores and immature cleistothecia, but may be unable to infect mature cleistothecia. For the next 7-10 days, the mycoparasite spreads within the hyphae of the host colony without killing it after which the process of pycnidial formation begins which is completed within 2-4 days. Infected cells generally die soon after pycnidial formation begins.
Benefits of Ampelomyces quisqualis
The fungus Ampelomyces quisqualis infects and forms pycnidia (fruiting bodies) within powdery mildew hyphae, conidiophores (specialized spore-producing hyphae), and cleistothecia (the closed fruiting bodies of powdery mildews). This parasitism reduces growth and kills the mildew colony. The mycoparasite is specific to powdery mildews (Erysiphales), but has an extremely broad host range within this diverse group of important plant pathogens.
Extremely safe to mammals, human beings, animals, natural parasites, predators, non target insects, fishes, birds, etc. No phytotoxicity and exempted from residue analysis.
