Title : Eco-friendly alternatives such as the use of biocontrol agents and biofertilizers on different media: Trichoderma Species
Abstract:
Eco-friendly alternatives such as the use of biocontrol agents and biofertilizers should be practiced as substitutes to the synthetic chemicals in this present day. Trichoderma has been studied widely. It has been found to play a major role in agricultural production. Around the world scientists and farmers have taken advantage of this knowledge. It is reported to improve plant growth of many crops such as tomato, lettuce, maize, beans, cabbage sugarcane and many more crops. There are two broad categories where Trichoderma plays a major role which is its use as a biofertilizer as well as a biofungicide. Its use as a biofertilizer has been aggravated by its ability to produce volatile compounds, ability to solubilize phosphates making them available to the plant. Among the biological alternatives, biopesticides have gained prominence due to their target specificity, environmental safety, and low toxicity compared to conventional agrochemicals. Trichoderma species, particularly Trichoderma harzianum, are well- established for their multifaceted roles in plant disease suppression, plant growth promotion, and enhancement of soil health. This study explores the bulk cultivation of Trichoderma spp using various cereal-based substrates to identify the most effective materials for the development of a talc-based biopesticide formulation. Experimental results revealed that maize and mixed grain substrates significantly supported optimal fungal growth, while rice and wheat were comparatively less effective. The formulated biopesticide demonstrated high viability, prolonged shelf life, and consistent field performance under sustainable agricultural practices. Statistical analyses validated uniform and reproducible growth patterns across the selected substrates. The outcomes of this study highlight the promise of T. harzianum as a potent, environmentally sound biocontrol agent and a viable substitute for chemical pesticides. The various beneficial aspects of Trichoderma species as biocontrol agent and biofertilizers as they are claimed as an effective and successful commercial agent in controlling various plant diseases and promote plant growth.
