Abstract

Parthenium hysterophorus, also called Congress grass, is a problematic weed within Indian agroecosystems, inflicting notable economic and ecological repercussions. This study examines the potential of employing Zygogramma bicolorata, commonly known as the Mexican beetle, as a biological control solution against Parthenium hysterophorus. The research assesses the practicality and efficiency of integrating Zygogramma bicolorata to combat Parthenium hysterophorus infestations in agricultural areas across India.

Conclusion

The introduction of Zygogramma bicolorata, known as the Mexican beetle, has demonstrated effectiveness as a biological control solution for combating the invasive weed Parthenium hysterophorus in Indian agroecosystems. Over, one year, the study observed a significant reduction in weed density by approximately 80% in treatment plots across Maharashtra. This reduction was accompanied by increased biodiversity, as indicated by the higher Shannon Diversity Index values in treated areas, highlighting the ecological benefits of controlling Parthenium hysterophorus.

Moreover, the study demonstrated a notable improvement in crop yields in fields adjacent to treatment plots, with an average increase of around 10%. This suggests that the effective management of Parthenium hysterophorus not only mitigates its negative impact on native flora but also enhances agricultural productivity.

These findings underscore the potential of Zygogramma bicolorata as a sustainable and environmentally friendly alternative to chemical herbicides, contributing to Integrated Weed Management (IWM) strategies. The study recommends the widespread adoption of Zygogramma bicolorata, supported by farmer training, policy and regulatory support, continuous monitoring, and integration with other weed management practices. By implementing these recommendations, stakeholders can promote sustainable agriculture, improve crop yields, and protect biodiversity in Indian agroecosystems.
