ABSTRACT: Fusarium oxysporum causes Fusarium wilt of crop plants leads to considerable yield loss. The study was conducted to determine the beneficial effects of combining Trichoderma species and Pseudomonas fluorescens i.e Trichodema viride+ Pseudomonas fluorescens (Tv+Pf) (1+2%), Trichoderma harzianum+Pseudomonas fluorescens (Th+Pf) (1.5+2%), Trichoderma viride +Trichoderma harzianum (Tv+Th) (1+1.5%) on the activity of cellulolytic enzymes of Fusarium oxysporum to control Fusarium wilt of Arachis hypogaea. L wilt in vitro. The activity of 1,4 -β – Endoglucanase, 1,4 -β – Exoglucanase, Cellobiases produced by Fusarium oxysporum (Control) was higher. Maximum inhibition of Cellulolytic enzymes was shown by culture filtrate of Trichoderma viride + Pseudomonas fluorescens (Tv+Pf) (1+2%), followed by Trichoderma harzianum + Pseudomonas fluorescens, (Th +Pf) (1.5+2%) and Trichoderma viride + Trichoderma harzianum (Tv+Th) (1+1.5%). However, disease suppression of Fusarium wilt of Arachis hypogaea. L by the compatible combination of Trichodema viride + Pseudomonas fluorescens (1+2%) was considerably better as compared to other two strains. At the same time the other two combinations resulted in enhanced disease suppression as compared to single strains. This indicates that the potential benefits of using combination treatments to suppress Fusarium wilt. The study suggests the significance of interactive effects of Trichoderma and Pseudomonas in biocontrol of wilt disease.

Effectiveness of the application of organic matter and Trichoderma viride from suppresive soil to control fusarium wilt on banana plant. Fusarium wilt disease caused by Fusarium oxysporum f.sp. cubense is one of the problems in banana production. This research was aimed to evaluate the effect of  Trichoderma viride isolated from suppresive soil and organic matter on controlling fusarium wilt on banana plant. The efficcacy trial consisted of 12 treatments and four replications within each treatment. Each experimental unit consisted of 10 plants. Organic matters used were rice straw, cassava peel, and compost. Treatments were arranged in a randomized complete block design. Data obtained were analyzed by analysis of variance followed by orthogonal analysis (P≤0.05). Application of T. viride suppressed disease incident up to 65%. The highest disease incident occurred in plants treated without T. viride and organic matter and in plants treated with organic matter only (78.33%). Disease incidence in plants treated with T.viride was lower than those treated with the combination of T. viride and organic matter. Different application times (in nursery or soil medium) did not significantly affect fusarium wilt incidence. The type of organic matter did not significantly affect the incidence and severity of fusarium wilt.

The aims of the research were to determine the best organic matter as carrier for growth and increasing the density of Trichoderma viride strain TV-T1sk (TV-T1sk) and its influence on Fusarium wilt disease development on banana seedling.  This research consisted of two experiments, i.e. (1). Growth  testing of TV-T1sk  in various organic matter, (2). Various organic matter testing for increasing the density of TV-T1sk in banana rhizosphere and its influence on  Fusarium wilt desease development.  The treatments were various organic matter, namely rice straw, sugar cane pulp, rice bran+banana plant waste,  hull of rice+sugar cane pulp and rice. The variables observed were  density and viability of conidia on various organic matter. Propagule density after introduction to banana rhizosphere was determined by observing TV-T1sk propagul from the rizosphere of banana seedling. The influence of density on Fusarium wilt disease development was determined by incubation period, the percentage of symptomized leaves and the intensity of corm damage. The results showed that both sugar cane pulp and rice were the best organic matter  for increasing  the growth and the density  of TV-T1sk  after introduction to banana rhizosphere. The density of TV-T1sk propagule on banana rhizophere influenced  the development of Fusarium wilt disease.

In an attempt to develop biocontrol system for management of Fusarium wilt in groundnut, Trichoderma viride, Trichoderma harzianum,and Pseudomonas fluorescens were evaluated for their antagonistic activity against Fusarium oxysporum in vitro. .Fusarium wilt diseasescaused by the fungus Fusarium oxysporum lead to significant yield losses of crops. Experiments were conducted on the effect of culture filtratesof T.viride (1%), T. harzianum (1.5%), and P. fluorescens (2%) on the in vitro inhibition of cellulolytic enzymes of Fusarium oxysporum. Theactivity of 1,4 endoglucanases, 1,4exoglucanase Cellobiase produced by Fusariumoxysporum was higher, when compared to control.Maximum inhibition of above Cellulolytic enzymes (1, 4 endoglucanases, 1,4exoglucanase, Cellobiase) was shown by T. viride treatment wasfollowed by T. harzianum and P. fluorescens. Of all the treatments, T. viride treatment showed higher rate of inhibition of Cellulolytic enzymesof Fusarium oxysporum followed by that of T. harzianum and P. fluorescens.This present study indicates that culture filtrate of T.viride(1%)is the best biocontrol agent in the inhibition of Fusarium oxysporum causing Fusarium wilt of Arachis hypogaea .LDOI: http://dx.doi.org/10.3126/ijasbt.v3i1.12138    Int J Appl Sci Biotechnol, Vol. 3(1): 106-110

Biological Soil Disinfestation

The influence of crop rotation and wheather conditions on the <i>Fusarium</i> population in soil and on <i>Fusarium</i> wilt of flax was examined in the Institute of Native Natural Fibres in 1968-1975. The experiments were carried out in various regions of flax planting in Poland during 8 years. Crop rotation had a significant influence on the process of biological soil disinfestation. <i>Fusarium</i> population in soil increased after planting flax, wheat, barley and sugar-beet, and decreased or did not change after rape, hemp, potato and leguminous plants. The crop rotation significantly influenced the composition of the <i>Fusarium</i> population as far as species are concerned. The highest wilt infection of flax was found in plantings after flax, sugarbeet and wheat and the weakest in plantings after rape. A six-year crop rotation was sufficient to eliminate the wilt pathogen from infested soil. But on flax-sick soil the process of biological disinfestation proceeded more slowly and a seven-year interval between flax crops was too short.
