Rice is the oldest staple crop ranked in 3rd number globally. In Pakistan, it is also contributing to the main cash crop. During the wet season, the chances for algae growth are also enhanced as the water from rivers, creeks and reservoirs used on the rice crop, hold a higher level of background nutrients. The possible effect of algae could be greater on germination during the early growth of rice seedlings. Respiratory and photosynthetic gases become trapped in the filaments tangled around seedlings, uprooting many seedlings which are not yet securely anchored. The filaments of algae grow on the same nutrients as rice seedlings and represent a severe drain on the available nutrients. The available treatments are limited so farmers should take action at the early stages of its growth. Circulate the field water and examine the crop at daily basis. Farmers can use Chelated copper (Coptrol) to control the algae growth. It is a special kind of organic algaecide which is much more effective at killing algae and does not harm plants and livestock, when used per label directions.
