Effectiveness of some integrated disease management factors (IDM) on Fusarium wilt infected tomato

Abstract

The study was conducted to investigate efficacy of Integrated disease management (IDM) viz., solarized soil, Trichoderma harzianum, spent mushroom compost and carbendazim on growth characteristics of infected tomato by Fusarial wilt (Fusarium oxysporum f.sp. lycopersici) under pots conditions in the Bio-net house during 2013-2014. Seven treatments and five replicates were taken up in completed randomized design. Maximum shoot length, fresh and dry shoot weight were noticed in T4 (solarized soil+ Spent mushroom compost+ T. harzianum) 118.10 cm, 67.25 and 42.20 g respectively as compared to T. harzianum or spent mushroom compost that alone treated plants. Maximum root length, fresh and dry root weight were also recorded in T4 (solarized soil+ spent mushroom compost+ T. harzianum) 28.35 cm, 4.65 and 2.55 g respectively. The yield of tomato plants was significantly increased in T6 (tomato plant alone without Fusarium oxysporum) 170.15 g/plant followed by T4 137.52 g/plant as compared with T0-Fusarium oxysporum alone and T1-Solarized soil + Fusarium oxysporum 0.0 g.

Optimization of culture conditions for the production, antifungal activity and characterization of secondary metabolites of <i>Trichoderma longibrachiatum</i>

“…Several strategies comprise the use of disease-resistant cultivars, adequate water and soil management, fertilization, crop rotations, and Biological Control Agents (BCA) to maintain or boost agricultural productivity by applying fewer chemical pesticides. (Salim et al, 2017) The study of alternate approaches to managing fungal infections has grown significantly (Villa et al, 2017;Das & Pattanayak, 2020). Among various beneficial categories of microorganisms, endophytic microorganisms exist without ever inflicting plant diseases on healthy plant tissues.…”

Endophytic Trichoderma strains isolated from forest species of the Cerrado-Caatinga ecotone are potential biocontrol agents against crop pathogenic fungi

“…Research on alternative methods of controlling fungal diseases has been widely developed, often requiring the integrated implementation of several methods, known as integrated disease management (IDM) [2,4]. Among these methods are the use of disease-resistant cultivars, adequate water and soil management, fertilization, crop rotations, and biological control agents (BCA), aiming to maintain or increase agricultural production with a reduced application of chemical agents [5]. Many studies still need to be developed for the use of biological control of plant pathogens on a global scale, since biopesticides represent only approximately 2% of all pesticides sold in the world [6,7].…”
