What are the control methods for Spirogyra in rice fields?
The flocculent masses of Spirogyra in rice fields press and entangle the seedlings, causing delayed development, dead seedlings, or single plants with no tillering; they lower the water temperature, and when the Spirogyra coverage reaches 30%, they can reduce the water temperature by 2-3°C; when Spirogyra occurs in large amounts in rice fields, the applied fertilizer cannot reach the rice
