Resistance Test of Several Rice Varieties on Root Puru Nematode Attacks

Understanding the Threat of Root Puru Nematodes

Root puru nematodes (Meloidogyne spp.) are a type of plant pest that has a broad host range and is found globally. These nematodes can infect rice plants during the nursery phase and vegetative growth, resulting in significant losses for crop sharing. To combat this issue, using rice varieties that are resistant to root puru nematodes is an effective solution. In this article, we will discuss the results of a research study conducted by Muhammad Aditya Ramadhan in 2020 at the Faculty of Agriculture, University of North Sumatra, which aimed to test the resilience of several rice varieties against Meloidogyne SPP attacks.

Research Methodology

The research study was conducted at Kasa's house for two months, using five rice varieties: Inpari 17, Inpago 9, Inpari 8, Inpari 24, and Inpari Sidenuk. The study aimed to categorize the rice varieties based on their level of resistance to root puru nematodes. The results of the study showed that there were three categories of plant resistance to root puru nematodes: vulnerable, rather vulnerable, and somewhat resistant.

Categorization of Rice Varieties

The results of the study showed that:

*** Inpari 17 and Inpago 9 varieties are categorized as vulnerable against nematode attacks. This means that the variety is very easily infected and shows severe symptoms of attack.***

*** Inpari 8 variety and sidenuk inpari are categorized as rather vulnerable. This variety shows symptoms of attacks that are lighter than vulnerable varieties.***

*** Inpari 24 varieties are categorized as somewhat resistant. This variety shows the lightest attack symptoms and has a better level of endurance compared to other varieties.***

Implications of the Study

This study provides important information about the level of resistance of several rice varieties to root puru nematode attacks. This information is very useful for farmers to choose rice varieties that are more resistant to nematode attacks and can help improve their crops. The study highlights the importance of selecting resistant varieties in efforts to suppress nematode attacks and increase rice productivity.

Integrated Approach to Root Puru Nematode Control

In addition to using resistant varieties, root puru nematode control can be done in various ways, such as:

**Plant Rotation: ** Planting plants that do not become a host for root puru nematodes on attacked land can help reduce the population of nematodes.

**The Use of Organic Fertilizer: ** Organic fertilizer can increase the profitable microorganism population in the soil, so that it can suppress the nematode population.

**Nematicide Application: ** Application of nematicides can help control the population of root puru nematodes, but the use of nematicides must be done wisely and according to recommendations so as not to damage the soil ecosystem.

Conclusion

The control of root puru nematodes requires an integrated approach that involves various methods. The selection of resistant varieties is one important step in efforts to suppress nematode attacks and increase rice productivity. By understanding the level of resistance of several rice varieties to root puru nematode attacks, farmers can make informed decisions about which varieties to plant and how to control nematode populations. This study provides valuable information for farmers, researchers, and policymakers to develop effective strategies for managing root puru nematodes and improving rice productivity.

Recommendations

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

Farmers should choose rice varieties that are resistant to root puru nematodes, such as Inpari 24.
Plant rotation and the use of organic fertilizer can help reduce the population of nematodes.
Nematicide application should be done wisely and according to recommendations to avoid damaging the soil ecosystem.
Further research is needed to develop more effective and sustainable methods for controlling root puru nematodes.

Future Directions

This study highlights the importance of selecting resistant varieties in efforts to suppress nematode attacks and increase rice productivity. Future research should focus on developing more effective and sustainable methods for controlling root puru nematodes, such as:

Developing new rice varieties that are resistant to root puru nematodes.
Investigating the use of biological control agents, such as beneficial nematodes, to control root puru nematodes.
Developing integrated pest management (IPM) strategies that combine multiple methods for controlling root puru nematodes.

By continuing to research and develop effective methods for controlling root puru nematodes, we can improve rice productivity and reduce the economic losses caused by these pests.
Frequently Asked Questions (FAQs) about Root Puru Nematodes and Rice Varieties

Q: What are root puru nematodes and how do they affect rice crops?

A: Root puru nematodes (Meloidogyne spp.) are a type of plant pest that can infect rice plants during the nursery phase and vegetative growth, resulting in significant losses for crop sharing. They can cause stunted growth, reduced yields, and decreased quality of rice.

Q: What are the symptoms of root puru nematode infection in rice crops?

A: The symptoms of root puru nematode infection in rice crops can include stunted growth, yellowing or browning of leaves, and reduced yields. In severe cases, the roots of the plant may become galled or distorted.

Q: How can farmers prevent root puru nematode infection in their rice crops?

A: Farmers can prevent root puru nematode infection in their rice crops by using resistant varieties, practicing good agricultural practices, and implementing integrated pest management (IPM) strategies. This can include rotating crops, using organic fertilizers, and applying nematicides.

Q: What are the benefits of using resistant rice varieties against root puru nematodes?

A: The benefits of using resistant rice varieties against root puru nematodes include reduced losses due to nematode infection, improved yields, and increased quality of rice. Resistant varieties can also reduce the need for chemical pesticides and other control measures.

Q: How can farmers choose the right rice variety for their needs?

A: Farmers can choose the right rice variety for their needs by considering factors such as climate, soil type, and pest pressure. They can also consult with agricultural experts or conduct their own research to determine which variety is best suited for their specific conditions.

Q: What are some other methods for controlling root puru nematodes in rice crops?

A: Some other methods for controlling root puru nematodes in rice crops include:

Plant rotation: Planting non-host crops in the rotation can help reduce nematode populations.
Organic fertilizers: Using organic fertilizers can increase beneficial microorganisms in the soil, which can help suppress nematode populations.
Nematicide application: Applying nematicides can help control nematode populations, but must be done wisely and according to recommendations to avoid damaging the soil ecosystem.

Q: How can farmers integrate multiple control methods to manage root puru nematodes?

A: Farmers can integrate multiple control methods to manage root puru nematodes by combining resistant varieties with other control measures such as plant rotation, organic fertilizers, and nematicide application. This can help reduce nematode populations and improve rice yields.

Q: What are some future directions for research on root puru nematodes and rice varieties?

A: Some future directions for research on root puru nematodes and rice varieties include:

Developing new rice varieties that are resistant to root puru nematodes.
Investigating the use of biological control agents, such as beneficial nematodes, to control root puru nematodes.
Developing integrated pest management (IPM) strategies that combine multiple methods for controlling root puru nematodes.

Q: How can farmers access more information about root puru nematodes and rice varieties?

A: Farmers can access more information about root puru nematodes and rice varieties by consulting with agricultural experts, attending workshops or training sessions, and visiting online resources such as the International Rice Research Institute (IRRI) or the Food and Agriculture Organization (FAO) of the United Nations.
