6 The bark of C. decandra is used for coloring (dye) the fishing nets. An antimicrobial activity on phytopathogenic fungi was studied using hexane, chloroform and methanol extracts of C. decandra, a mangrove plant. 7 The phytopathogenic fungi Pythium aphanidermatum causes damping-off in majority of solanaceous crops. Rhizoctonia solani (Sheath blight and damping-off) and Pyricularia oryzae (Rice blast) are important phytopathogens. They mainly infect rice crops and causes serious damages. Fusarium oxysporum, a soil born fungus

shows infections in chilli and rice crops. All these phytopathogenic fungi cause severe diseases in crop varieties. The chloroform, petroleum ether, methanol and ethanol leaf extracts PD173074 of C. decandra showed moderate antifungal and antibacterial activity. 8 The phytochemical constituents of the C. decandra whole plant composed with diterpenoids, triterpenoids, Cilengitide mouse phenolic compounds, and steroids. Terpenoids are the predominant compounds in the Ceriops plants and exhibited antimicrobial activity, anticancer activity, antitumor and larvicidal activities. Forty-three diterpenes and twenty-nine triterpenes

have been reported from embryos, fruits, hypocotyls, roots, stems, and twigs of C. decandra. 9 The root extracts of C. decandra resulted in the isolation of new diterpenoids, ceriopsins A–D and ceriopsins F and G. 10 and 11 In India Spodoptera litura is a notorious pest on tobacco and for the last and 30 years, a major pest to other crops like cotton, groundnut and mung bean. It is very difficult to control the wide spreading of this pest through insecticides because of the development of drug resistance; hence other alternative eco friendly pest management methods are required to control the wide spreading infections due to pests. A. aegypti mosquito is the major vector of dengue fever disease. Search

for larvicidal active compound(s) is one of the several attempts to find effective and affordable ways to control this mosquito. The present study was aimed to investigate the potent phytochemical constituents of C. decandra leaf organic solvent extracts were determined by GC–MS and the extracts were subsequently tested for antifungal & larvicidal activities. Fresh leaves of C. decandra (Griff.) Ding Hou (Rhizophoraceae) were collected from Kandikuppa Mangrove forest area, which was extended from Coringa Mangrove wetland Forest, up to Konaseema deltaic zone through Godavari estuarine located at 16° 35′ 12.89″ N and 82° 16′ 17.03″ E, of East Godavari district, Andhra Pradesh. The plant material was identified taxonomically and a specimen voucher was preserved in the Department of Biotechnology, Acharya Nagarjuna University. The plant material was dried under shade with occasional shifting and then powdered with a mechanical grinder and stored in an airtight container.
