防控措施：
（ 一）農業措施：一是及時清除田間、地邊雜草，破壞灰飛虱的生存環境，降低灰飛虱蟲口密度，減少傳毒機率。二是加強肥水管理，促進作物健壯生長，提高其抗病性。三是結合間苗定苗,拔除病株，避免成為再侵染的毒源。四是適期晚播，各地根據當地情況，適時推遲夏玉米播期,避免傳毒昆蟲活動高峰期與玉米易感生育期相吻合；五是水稻上大力推廣防蟲網育秧，防止灰飛虱接觸水稻秧苗傳毒。
（二）化學防治措施：一是沒有用防蟲網覆蓋的水稻秧苗田，每畝用25％撲虱靈40－50g加10％吡蟲啉可濕性粉劑15g或50%吡蚜酮水分散粒劑每畝8-12g對水30－40kg噴霧。二是玉米田：在播種前提倡種子包衣或吡蟲啉、噻蟲嗪等藥劑拌種；玉米幼苗期藥劑防治，每畝用25％撲虱靈40－50g加10％吡蟲啉可濕性粉劑15g或50%吡蚜酮水分散粒劑每畝8-12g對水30－40kg噴霧。
