In vitro study on the effect of four Trichoderma isolates on the mycelial growth of Rhizoctonia solani showed maximum inhibition of 74.54 per cent and least inhibition of 52.50 per cent. Effects of volatile compound produced by Trichoderma spp. against R. solani were ranged from 15.50 to 26.70 per cent.

During 2015-16 survey was conducted in six different soybean growing areas of Manipur, India. The survey revealed that the maximum mean pod blight intensity was at Thoubal (21.23%) and minimum (13.82%) at Andro Research Farm, CAU. Fusarium oxysporum was isolated and identified by morphological characteristics and gene sequencing, MF512000. The pathogen was found to be the causal organism of pod blight of soybean. Total genomic DNA of the fungal cultures was extracted by using HiPurA DNA isolation Kit (HiMedia, India).

The aim of the study was to access the anti-bacterial and anti-fungal activity on the growth of Alternaria porri under in vitro condition. The antagonistic activity of bacterial and fungal antagonists (Pseudomonas and Trichoderma spp.) was determined by the dual culture technique both on King’s B and PDA media respectively, Paper disc assay and Agar well mathod. Plates were incubated at 28ºC for 7 days and 2 days. The antagonistic activity of these antagonists was evaluated by mycelial growth and mycelial dry weight of test fungus (Alternaria porri).

The present study was undertaken to analyze the effect of the native Trichoderma spp., isolated from the rhizosphere of ghost pepper (Capsicum chinense) against root rot caused by Rhizoctonia solani. Rhizospheric Trichoderma spp. were isolated from ghost pepper growing sites of Manipur and screened for their biocontrol potential against Rhizoctonia solani. Four fungal isolates were isolated and selected based on morphology and growth pattern. Molecular identification was carried out and an amplicon size of 262 bp were generated for fungus.

Biological control represents an important approach to manage plant diseases. Blights of leaf, panicle and fruits caused by Alternaria alternata and the wilt caused by Fusarium solani are important diseases of litchi. Hence, as an alternative to chemical fungicides, biological control by Trichoderma spp. to manage pathogens of litchi was explored. The aim of this study was to isolate native Trichoderma spp. from litchi orchard ecosystem and to evaluate antagonistic potential and its biological fitness so as to develop a commercial formulation for field application to manage litchi diseases.

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.

Sclerotium rolfsii Sacc, [teleomorph: Athelia rolfsii (Curzi)] causing collar rot of chickpea, is a devastating soil-borne fungus. It is reported almost all over the world with 10 to 30% yield loss is recorded annually according to severity of the disease. It is more serious at seedling stage causing plant mortality ranged from 54.7 to 95%. The present investigation was undertaken to find out bio-efficacy of twenty native isolates of Trichoderma spp.

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.

Use of biocontrol agents against soil borne pathogen is gaining importance in the present situation for eco-friendly management of soil borne diseases. Bioefficacy of indigenous Trichoderma spp has greater efficacy against soil borne pathogens of pulses. Native Trichoderma isolates were collected from soil rhizospheres of paddy, groundnut, brinjal and tomato grown in the Agronomy field and Central farm of Orissa University of Agriculture and Technology, Bhubaneswar and named as Isolate 1, Isolate 2, Isolate 3, Isolate 4, Isolate 5 respectively.

The present study was conducted to evaluate the in vitro efficacy of native Trichoderma spp. against Pythium spp. and Rhizoctonia solani (Kuhn.) causing damping-off disease in Tomato. One hundred eighty soil samples were collected from 11 districts of Meghalaya and ninety seven Trichoderma isolates were obtained. Rapid screening against damping off pathogens (Pythium spp. and R. solani) of tomato revealed that 20 isolates showed maximum antagonism and subsequently 20 best isolates were selected for further analysis.
