Evaluation Of Selected Agroallied Wastes As Carrier For Trichoderma harzianum

Abstract

This study was carried out to estimate the effectiveness ofagro-allied wastes as carriers of the natural control organism,T. harzianum, by assessing colonization and sporulation rate of each. The named substrates were sludge cocoon, Alstonia and Iron wood. The substrates were supplemented with 5, 10, 15, and 20 of rice bran, and control treatment to show the bettered rate of colonization. All substrate used proved to be effective. The slowest mycelia colonization rate was from the Iron wood with 50 at 10 rice supplement by day- 5. Alstonia and cornhusk substrates at 10 proved to be the stylish with a fast chance colonization of77.5 and85.5 by day- 5. This result were analysed using one way ANOVA at 5 probability position using Student- Newman- Keul’s( SNK).

Chapter One

Preface

Trichoderma a fungus belonging to the division Ascomycota( Imperfecti fungi) and to the family Hypocreales. They do worldwide and are generally associated with roots, soil and factory debris( Howell etal., 2003). They could survive on other host similar as rotten tomatoes and societies of sawdust when the terrain is favourable( Apabalza etal., 2000).

They live in symbiotic relationship similar as competitions, antibiosis and mycoparatism. Trichoderma species have a complex mycoparatism process where they cache cell- wall demeaning enzymes( Whipps, 2011). In the cell wall chitin which a polymer include endochitin, chitinolytic which degrade the cell wall and metabolism of organism( Goku etal., 2000).

Trichoderma is an important phytopathogen antagonist against some soil fungi and factory parasitic organism( nematodes). Different strains have being developed similar as TH 36, TH16 and has been proved to be effective antagonist of conidia of Colletotrichum musae( banana spoilage) and Rhizoctonia solani unproductive organism of seedling wilt in numerous factory( Apabalza etal., 2000 Kerry, 2000 and Myer, 2001).

The use of bactericide and pesticides(e.g. Aldrex T) and use of chemical toxin in crop protection have being in use over the times; lately this form of crop protection are being discouraged due to its recrimination on the terrain( Chanidallan and Eliot, 2009).

The use of natural control has been on the rise and emphasis are being placed on it due to the fact that it’s environmentally friendly( Whipps, 2001).

Trichoderma has been set up to produce and give better protection for crops similar as cowpea by populating the factory root( Adekunle etal., 2004) and effective in repression of pathogens by contending for space, nutrients and stashing of diffusible antibiotics( Howell, 2003).

Trichoderma has been used as germicide against foliar complaint of crops and its effectiveness against damping off. As biocontrol they act laterally or directly through their medium help ameliorate environmental conditions, factory growth and induce systemic resistant.( Benitez, 2004).

Test conducted using colorful species of Trichoderma has shown them to be effective in seed treatment; Trichoderma konigii, Trichoderma harziaum and Trichoderma virivde used to treat seedling against soil borne complaint like Marcophonmia phaseolina( Adeknule etal., 2000). Good and bettered the resistance of tomatoes to Meloidogyne incognita when dressed in1.5 tomatoes excerpts( Dabbat AA etal., 2006).

The product of Trichoderma for use in the field would bear fast growth performing in large biomass. Vacuity of cheap substrate and energy source is of significance.

The ideal of this study is to determine

The felicity of named agro confederated waste as carrier for Trichoderma harzianum

The rate of colonization and sporulation in named agro confederated waste.

The effect of soil correction on growth and yield of a named vegetable- Celosia argentea.
