How to Control Algae in Rice Crops
Inhibition of seedling germination and vigour - Plant
pathologists suggest the possible effect of algae could
be greater than that of fungi on germination during early
growth of rice seedlings.
Uprooted seedlings - Respiratory and photosynthetic gases
become trapped in the filaments tangled around seedlings,
uprooting many seedlings which are not yet securely anchored.
Competition for nutrients - Slime lives and grows on the same nutrients as rice seedlings. In a blooming population the sheer numbers of algal cells are enormous and represent a severe drain on the available nutrients.
Seedling knockdown and smother - When filaments of algae are in huge numbers they smother and drown the emerged seedlings and a tremendous amount of damage has already been done. Remedial treatments will salvage the crop but it is obviously better to avoid this damage before it happens. A good seedling stand is essential for high yields.
