A Growing Threat: The Two-Spotted Leafhopper Infestation
South Carolina's okra growers are grappling with an unprecedented challenge this agricultural season: a sweeping infestation of the two-spotted leafhopper, a pest that is wreaking havoc on crops throughout the eastern counties. This invasive insect, known scientifically as the "cotton jassid," has created alarming conditions for farmers who previously considered okra relatively resilient to pests.
Impact on Crops and Farming Strategies
The devastation caused by the leafhopper manifests as yellowing leaves and reduced yields, leading to complete crop loss in severe cases. Recent discussions among growers reveal a deeply concerning trend that farmers like Chris Sumter from Sumter County have never encountered in their farming careers. Sumter, who has cultivated okra for over a decade, emphasizes the need for new strategies, like utilizing greenhouses to safeguard younger plants and spacing them strategically to thwart the spread of the pest.
Adapting to Challenges with Research and Collaboration
Extension experts, including Zack Snipes from Clemson University, note that the two-spotted leafhopper has also been reported on other crops such as eggplant and sunflowers, though the damage remains less detrimental to those plants. The agricultural community's best line of defense currently involves the use of Beleaf, a Group 29 insecticide effective for vegetable cultivation. However, there is a looming worry about insect resistance, which has prompted discussions about integrating rotational partners and exploring alternative insecticide options.
A Call for Collective Action and Future Readiness
As the situation develops, Clemson Extension experts are collaborating closely with farmers, gathering crucial data to monitor pest activity and develop tailored management strategies. These efforts are vital, as the economic impact on growers is significant—okras produced in South Carolina have an estimated value of over $2.4 million. In a year that has already posed various agricultural challenges, it's crucial for farmers and researchers to leverage every available resource to combat this growing threat and safeguard the state's vital okra production.
