In the present investigation 30 Plant leaf extract were evaluated in in vitro condition against P. palmarum adopting poisoned food technique. The per cent inhibition of pathogen was 100 per cent by Dhatura, Anjwain and Tobacco at 10 per cent concentration followed by the turmeric (95.84), safed musli (90.62), garlic (87.5), hathjodh (86.5), kalmegh (86.46), jetropha (83.34), neem bark (79.18), satavar (78.12), lemongrass (69.81), laung (67.71), ashoka (65.62), aadusa (63.68), karanj bark (63.06), bhringraj (62.5), karanj (62.5), dalchini (61.15), beshram (60.43), brijdanti (57.

Coconut nut rot disease is one of the major economic constraints which hampers coconut production in India. An extensive disease survey was conducted during July 2015 - September 2016 to assess the nut rot incidence in major coconut growing tracts of Tamil Nadu. The young palms of 5-10 years were found to be more susceptible to nut rot than matured palms. A fungal pathogen was found to be consistently associated with nut rot disease and identified as Lasiodiplodia theobromae based on morphological characters.

Stem bleeding disease caused by Thielaviopsis paradoxa is one of the major diseases of coconut in almost all the coconut growing regions of Andhra Pradesh. Bioefficacy of native bioagents viz., Trichoderma spp and Pseudomonas fluroscens on stem bleeding pathogen Thielaviopsis paradoxa under in vitro conditions revealed that all the three isolated native Trichoderma spp were found inhibitory to the mycelia growth of Thielaviopsis paradoxa on Potato Dexose Agar media.

In vitro antagonism of native biocontrol agents on coconut pathogens revealed that all the three isolated native Trichoderma spp were found inhibitory to the mycelia growth of Thielaviopsis paradoxa and Phytophthora palmivora. Maximum percent inhibition of mycelia growth of Thielaviopsis paradoxa and Phytophthora palmivora was obtained by Trichoderma viride followed by Trichoderma hamatum and Trichoderma harzianum.

Stem bleeding disease caused by Thielaviopsis paradoxa is one of the major diseases of coconut in almost all the coconut growing regions of Karnataaka. Bioefficacy of five botanicals viz. Allium sativa, Nerium olender, Tinospora cordifolia, Osimum sanctum and Aegle marmelos, Seven isolates namely Trichoderma viridae (GKVK), Trichoderma harzianum (GKVK), Trichoderma asperillum (GKVK), Trichoderma harzianum (HRS, NBAII, KRN and MYS) and ten systemic and three contact fungicides were evaluated under in vitro conditions against Thielviopsis paradoxa.
