“…(Pandey et al, 2005;Bernal et al, 2009). To date, strains of Trichoderma including T. harzianum are currently being commercialized because they exert strong competitive effects for space and nutrients; more importantly, they produce toxins against phytopathogenic species, thus making them excellent biocontrol agents (Zimand et al, 1996;Susanto et al, 2005;Sharoni et al, 2006). Hence, this BCA would be the most preferred component in an amendment of a biological control compost or biofertilizer.…”

Sustainability of the oil palm industry is crucial to ensure Malaysia's gross domestic product (GDP) by the agricultural sector. It is crucial to discover a sustainable and eco-friendly remedy for the most devastating Ganoderma disease of oil palm. The effects of pre-inoculation of oil palm seedlings with either Trichoderma harzianum and/or Bacillus cereus on their vegetative growth and the suppression of Ganoderma boninense were investigated. The dip, place and drench (DPD) artificial inoculation method was used to assure disease development. Disease severity was assessed based on the root symptoms (DS), disease incidence (DI) and disease reduction (DR). Application of a mixture of T. harzianum and B. cereus had the highest contribution to the vegetative growth of oil palm seedlings. However, single application of B. cereus was found to be the most effective treatment in suppressing Ganoderma disease of oil palm with a disease reduction of 94.75% followed by single applications of T. harzianum (78.98%) and mixture of both T. harzianum and B. cereus (68.49%).

“…It has been known for many years that they produce a wide range of antibiotic substances and that they parasitize other fungi (Sivasithamparam and Ghisalberti, 1998). In addition, they inhibit or degrade pectinases and other enzymes that are essential for plant-pathogenic fungi (Zimand et al, 1996).…”

Abstract. Field experiment was carried out at the experimental station of Szent István University, Gödöllő, Hungary to explore the impact of arbuscular mycorrhizal fungi only alone or together with Trichoderma and plant growth-promoting bacteria on defense enzymes and yield of three pepper varieties. The seven inoculation treatments consisting of arbuscular mycorrhizal fungi (AM), Trichoderma (Tri), plant growth promoting bacteria (Pse) and their combinations (AM+Tri; AM+Tri+Pse; AM+Pse) together with three pepper hybrids and non-inoculation (control) plants were arranged in a randomized complete block design. Defense enzyme activities polyphenol oxidase (PPO), peroxidase (POD), superoxide dismutase (SOD), catalase (CAT) of various treated plants were measured just before flowering, representing the most sensitive stage of plants. The results showed that AM+Tri+Pse treatment enhanced the yield most among microbial inoculations. Highest yield was recorded in the triple treatment in Karpex cultivar, however, Karpia and Kaptur variety obtained more improved yield by microbial inoculations. Defense enzymes activities generally were most induced in the combination of three inoculants in cultivars whereas different responses in induction of defense enzymes were found in other microbial treatments, depending on specific interactions between microbe and pepper genotype. These results suggested that the triple application brought more benefits to the host plant.

“…Abdullah et al (1999) were successful in plant house trials by using iso-late T. harzianum FA 1132, and they showed that the isolate has good antagonist properties against G. boninense and is effective in controlling disease development. Strains of T. harzianum are currently being commercialised because they exert strong competitive effects for space and nutrients; more importantly they produce toxins against phytopathogenic species, thus making them good bicontrol agents (Zimand et al 1996;Susanto et al 2005;Sharoni et al 2006).…”

Nur Ain Izzati M.Z., Abdullah F. (2008): Disease suppression in Ganoderma-infected oil palm seedlings treated with Trichoderma harzianum. Plant Protec. Sci., 44: 101-107.Disease suppression in Ganoderma-infected oil palm seedlings treated with a conidial suspension of Trichoderma harzianum FA 1132 was tested in plant house conditions to determine the effectiveness of the fungus as a biocontrol agent. The highest efficacy of control was achieved by treatment right after artificial infection; the total number of infected plants was reduced to give the lowest disease severity index (DSI) value of 5.0%, compared to the infected and non-treated control that had the highest DSI of 70.0%. After conidia suspension of FA 1132 was applied, the colony forming ability by Trichoderma in the soil was dramatically increased, but decreased after some time. Results of the present study are a useful reference basis for further tests in the field and large scale production trials.
