Eleusine Indica Weed Endurance Survey of Glyphosate Herbicides on Corn Land in East Java and Central Java

Introduction

The excessive use of herbicides in controlling weeds has led to the development of herbicide resistance in various weed species. This study aims to identify the population of weeds Eleusine Indica which is resistant to Glyphosate herbicides on corn land in East Java and Central Java. The use of herbicides has become a common practice in agriculture to control weeds, but the repeated use of the same herbicide can lead to the development of resistance in weeds. This study is crucial in understanding the dynamics of herbicide resistance and its impact on agricultural production.

Background

Weeds are a major problem in agriculture, causing significant losses in crop yields and quality. The use of herbicides has become a common practice in controlling weeds, but the repeated use of the same herbicide can lead to the development of resistance in weeds. Eleusine Indica, also known as goosegrass, is a common weed species found in tropical regions, including Indonesia. It is a highly competitive weed that can outcompete crops for water, nutrients, and light. The use of glyphosate, a non-selective herbicide, has become a popular choice for controlling weeds, but its repeated use can lead to the development of resistance in weeds.

Methodology

This study was conducted in East Java and Central Java, two provinces in Indonesia where corn is a major crop. Weed seeds Eleusine Indica were collected from several districts in the two provinces and then taken to the University of North Sumatra to be tested for its durability to glyphosate. The testing process involved taking seeds that had reached the leaf phase 3-5 and spraying them with two glyphosate doses, namely 540 g A.e/ha and 1080 g A.e/ha. Each dose consisted of three pots, where each pot contained ten plants. The results of the test showed that of the 94 populations tested, 64 populations showed signs of being resistant, while 18 other populations were still sensitive to glyphosate at a dose of 1080 g A.E/ha.

Results

The results of this study showed that 64 out of 94 populations of Eleusine Indica were resistant to glyphosate. This is a significant finding, as it indicates that the use of glyphosate has led to the development of resistance in weeds. The resistance to glyphosate can be caused by various factors, including the repeated use of the same herbicide without rotation, the use of herbicides at suboptimal doses, and the presence of resistant weed biotypes.

Discussion

The discovery that 64 out of 94 populations of Eleusine Indica has been resistant to glyphosate shows a serious problem in managing weeds in agricultural land, especially in corn plants. This resistance can be caused by various factors, including the use of glyphosate repeatedly without the rotation of herbicide or other weed control methods. Herbicide resilience can cause an increase in production costs for farmers, because they need to find alternative weed controls that are more effective.

Weed endurance can also affect the yield. Resistant weeds will compete with corn plants to get nutrition, water, and sunlight, which in turn can reduce agricultural products. Therefore, it is important for farmers to implement more diverse weed control strategies, such as the use of herbicides in a wise way, adopting mechanical methods, and applying plant rotation.

Conclusion

This study highlights the importance of understanding the dynamics of herbicide resistance in weeds. The repeated use of the same herbicide can lead to the development of resistance in weeds, which can cause significant losses in crop yields and quality. The results of this study show that 64 out of 94 populations of Eleusine Indica were resistant to glyphosate, indicating a serious problem in managing weeds in agricultural land. It is essential for farmers, researchers, and policymakers to work together to develop more effective weed control strategies that can minimize the development of herbicide resistance.

Recommendations

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

Education and awareness: It is essential to educate farmers, researchers, and policymakers about the importance of understanding the dynamics of herbicide resistance in weeds.

Understanding the mechanisms of herbicide resistance: Researchers should study the mechanisms of herbicide resistance in weeds to develop more effective weed control strategies.
Developing more effective weed control strategies: Researchers should develop more effective weed control strategies that can minimize the development of herbicide resistance.
Evaluating the impact of herbicide resistance on crop yields: Researchers should evaluate the impact of herbicide resistance on crop yields and quality to develop more effective weed control strategies.

Conclusion

In conclusion, this study highlights the importance of understanding the dynamics of herbicide resistance in weeds. The repeated use of the same herbicide can lead to the development of resistance in weeds, which can cause significant losses in crop yields and quality. The results of this study show that 64 out of 94 populations of Eleusine Indica were resistant to glyphosate, indicating a serious problem in managing weeds in agricultural land. It is essential for farmers, researchers, and policymakers to work together to develop more effective weed control strategies that can minimize the development of herbicide resistance.
