Rice water weevils are beginning to emerge as rice fields in Arkansas flood, signaling the need for quick action to control these pests. Timing is crucial, as experts recommend that foliar insecticide applications be made within five to seven days of flood establishment in order to achieve maximum effectiveness.
Researchers suggest sweeping areas 50 to 60 feet away from levee furrows to accurately assess rice water weevil populations, as they tend to favor open water. While a threshold based on the presence of adults is still being developed, growers should be prepared to apply foliar insecticide if a high population of adults is detected.
It’s important for rice farmers in the state to stay vigilant and take action promptly to protect their crops from these damaging pests. Effective management of rice water weevils is essential for a successful rice harvest.
