The Use of Trichoderma Harzianum Rifai and Compost Antagonist Fungus in Suppressing Fusarium Oxysporum F.Sp. Passiflora on Passion Fruit Nurseries

Introduction

In recent years, the use of chemical fungicides has become a common practice in agriculture to control plant diseases. However, the excessive use of these chemicals has led to environmental pollution and harm to human health. Therefore, the development of biological control methods is an indispensable alternative to reduce dependence on chemicals. One of the biological control methods that has gained attention is the use of Trichoderma Harzianum Rifai, a fungus that has been shown to have antifungal properties. In this study, we will discuss the use of Trichoderma Harzianum Rifai and compost antagonist fungus in suppressing Fusarium oxysporum F.Sp. Passiflora on passion fruit nurseries.

The Importance of Biological Control

The use of chemical fungicides has become a common practice in agriculture to control plant diseases. However, the excessive use of these chemicals has led to environmental pollution and harm to human health. The development of biological control methods is an indispensable alternative to reduce dependence on chemicals. Biological control methods use living organisms, such as fungi, bacteria, or insects, to control plant diseases. These methods are not only environmentally friendly but also cost-effective and sustainable.

Trichoderma Harzianum Rifai: A Biological Control Agent

Trichoderma Harzianum Rifai is a fungus that has been shown to have antifungal properties. It is a saprotrophic fungus that can colonize plant roots and soil, making it an ideal candidate for biological control. Trichoderma Harzianum Rifai has been shown to produce antibiotics that can inhibit the growth of fungal pathogens, including Fusarium oxysporum F.Sp. Passiflora. In this study, we will investigate the effectiveness of Trichoderma Harzianum Rifai in suppressing Fusarium oxysporum F.Sp. Passiflora on passion fruit nurseries.

Compost Antagonist Fungus: A Natural Fungicide

Compost antagonist fungus is a type of fungus that can be used as a natural fungicide. It is a saprotrophic fungus that can colonize plant roots and soil, making it an ideal candidate for biological control. Compost antagonist fungus has been shown to produce antibiotics that can inhibit the growth of fungal pathogens, including Fusarium oxysporum F.Sp. Passiflora. In this study, we will investigate the effectiveness of compost antagonist fungus in suppressing Fusarium oxysporum F.Sp. Passiflora on passion fruit nurseries.

Research Methodology

This study uses a complete factorial random design method with two main factors: Trichoderma Harzianum dose (25, 37.5, 50, and 62.5 grams per 1.5 kg of soil) and compost types (chicken compost and cow compost). In total, there are 10 combinations of treatment carried out with three replications to ensure the accuracy of the data obtained.

Research Results

The results showed that the highest disease incidence occurred in control treatment (T0), with a percentage of 30.07%. Conversely, the lowest disease incidence was found in T4KS treatment (dose of 62.5 grams), which is only 1.98%. Likewise, with the intensity of the disease, the control treatment shows the highest number, which is 10.2%, while the treatment with a dose of 62.5 grams shows the lowest number, which is 1.72%.

Analysis and Conclusion

Data obtained from this study shows that the use of Trichoderma Harzianum is significantly able to suppress the development of withered diseases caused by the fusarium oxysporum in passion fruit seeds. A higher dose of Trichoderma Harzianum has proven to be more effective in reducing the incidence and intensity of the disease, so that it can be used as a strategy in controlling plant diseases.

With this result, farmers and agricultural practitioners are expected to consider the use of biocontrol methods such as Trichoderma Harzianum and compost in an effort to reduce dependence on chemicals. This is not only beneficial for the health of plants, but also to preserve the environment. Further research is also advised to explore the mechanism of action of Trichoderma Harzianum and its effectiveness in more varied field conditions.

Recommendations

Based on the results of this study, the following recommendations are made:

Use of Trichoderma Harzianum: Trichoderma Harzianum can be used as a biological control agent to suppress the development of withered diseases caused by fusarium oxysporum in passion fruit seeds.
Compost Antagonist Fungus: Compost antagonist fungus can be used as a natural fungicide to suppress the development of withered diseases caused by fusarium oxysporum in passion fruit seeds.
Higher Dose of Trichoderma Harzianum: A higher dose of Trichoderma Harzianum (62.5 grams per 1.5 kg of soil) is more effective in reducing the incidence and intensity of the disease.
Further Research: Further research is needed to explore the mechanism of action of Trichoderma Harzianum and its effectiveness in more varied field conditions.

Conclusion

In conclusion, this study has shown that the use of Trichoderma Harzianum and compost antagonist fungus can be effective in suppressing the development of withered diseases caused by fusarium oxysporum in passion fruit seeds. A higher dose of Trichoderma Harzianum has proven to be more effective in reducing the incidence and intensity of the disease. Therefore, farmers and agricultural practitioners are expected to consider the use of biocontrol methods such as Trichoderma Harzianum and compost in an effort to reduce dependence on chemicals.
