Filamentous algae

Alga units form solid mass of brownish scum attached to soil surface or organic matter that floats to the water surface seen in newly flooded rice fields early season Management Prepare seedbed well to eliminate low spots Incorporate nitrogen and phosphate fertilizers to a depth of at least 2 to 4 inches, and do not apply after flooding Maintain water level at a depth greater than 3 inches Herbicides, e.g., copper compounds, applied before algal mats float to the water surface
