Trichoderma Harzianum Effectiveness Test and Giving Coconut Shell Charcoal as a Biological Control of Land Disease (Phytophthora Nicotianae de Hann) in Deli Tobacco Plants

Introduction

In the world of agriculture, the use of chemical pesticides has become a common practice to control plant diseases. However, the overuse of these chemicals can have devastating effects on the environment and human health. As a result, there is a growing need for environmentally friendly methods of disease control. One such method is the use of biological control agents, such as Trichoderma Harzianum, which has been shown to be effective in controlling plant diseases. In this study, we aim to test the effectiveness of Trichoderma Harzianum and the administration of coconut shell charcoal in controlling the disease caused by Phytophthora Nicotianae de Hann on Deli tobacco plants.

Background

Phytophthora Nicotianae de Hann is a type of fungal pathogen that can cause significant damage to tobacco plants. The use of chemical pesticides to control this disease has become a common practice, but it can have negative effects on the environment and human health. As a result, there is a growing need for environmentally friendly methods of disease control. Trichoderma Harzianum is a type of fungus that has been shown to be effective in controlling plant diseases. It is known to compete with pathogens, produce antimicrobial compounds, and improve soil conditions.

Research Methodology

This study uses a factorial random block design consisting of two factors and three replications. The first factor is t. Harzianum (T), which is divided into several treatments:

  • (T0) Without Treatment,
  • (T1) t. Harzianum incubated on corn media with a dose of 10 g/ plant,
  • (T2) with a dose of 15 g/ plant,
  • (T3) with a dose of 20 g/ plant.

The second factor is the administration of charcoal (A), which also consists of several treatments:

  • (A0) Without Treatment,
  • (A1) coconut shell charcoal at a dose of 20 g/ plant.

Research Result

The results showed that treatment without t. Harzianum and without coconut shell charcoal (T0A0) experienced the highest percentage of attack, which was 99.71%. Meanwhile, the combination treatment of t. Harzianum with a dose of 20 g/ plant and coconut shell charcoal with the same dose (T3A1) shows the lowest percentage of attacks of 0.71%. This shows a significant effectiveness of t. Harzianum and coconut shell charcoal in controlling the disease.

In addition, this research also records the number of leaves produced. T3 treatment (with t. Harzianum 20 g/ plant) produces the highest number of leaves of 11.67 strands, while in the control treatment (T0) there are only 7.17 leaves. This shows that the use of t. Harzianum together with coconut shell charcoal not only reduces disease attacks but also increases plant growth.

Additional Analysis and Explanation

The use of Trichoderma Harzianum as a biological control agent has been proven effective in this study. Trichoderma is a fungus that is known to be able to compete with pathogens, produce antimicrobial compounds, and improve soil conditions. Coupled with the use of coconut shell charcoal, which is rich in carbon and functions as a medium for microbial growth, the effectiveness of disease control can increase significantly.

The success in this study provides new hopes for tobacco farmers in overcoming environmentally friendly in the disease. With the application of biological control methods, it is expected to reduce dependence on chemical pesticides that can damage the ecosystem.

Conclusion

In conclusion, this study has shown the effectiveness of Trichoderma Harzianum and coconut shell charcoal in controlling the disease caused by Phytophthora Nicotianae de Hann on Deli tobacco plants. The use of biological control agents is a promising method of disease control that can reduce the negative effects of chemical pesticides on the environment and human health. This study provides valuable information for further research and is a reference for better and sustainable agricultural practices in the future.

Recommendations

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

  • The use of Trichoderma Harzianum and coconut shell charcoal should be promoted as a biological control method for plant diseases.
  • Further research should be conducted to explore the potential of Trichoderma Harzianum and coconut shell charcoal in controlling other plant diseases.
  • The use of biological control agents should be encouraged as a sustainable and environmentally friendly method of disease control.

Limitations

This study has several limitations that should be noted:

  • The study was conducted in a controlled environment, and the results may not be applicable to other environments.
  • The study only tested the effectiveness of Trichoderma Harzianum and coconut shell charcoal in controlling the disease caused by Phytophthora Nicotianae de Hann on Deli tobacco plants.
  • Further research is needed to explore the potential of Trichoderma Harzianum and coconut shell charcoal in controlling other plant diseases.

Future Research Directions

Based on the results of this study, the following future research directions are suggested:

  • Investigate the potential of Trichoderma Harzianum and coconut shell charcoal in controlling other plant diseases.
  • Explore the effects of Trichoderma Harzianum and coconut shell charcoal on plant growth and development.
  • Develop a commercial product that combines Trichoderma Harzianum and coconut shell charcoal for use in agriculture.
