Herbicide Ban Targets Water Hyacinth in Vietnam Waterways

Authorities in the Medong delta province of Hau Giang have banned local authorities from spraying herbicide to the water hyacinth. This fast growing plant has slowly been taking over and blocking waterway traffic on rivers and canals in the area.

Many people breed water hyacinth locally to use for making exportable products such as baskets and furniture. These breeders must also contribute to clearing the weed from the water and remove dredged roots from water by destroying them or throwing them on soil rather than back into the water where they will continue to propagate.

Authorities have been spraying 2-4D to kill the water hyacinth and warned people to stop using the water for 10 days. However many households along the rivers and canals have no other source of clean water and the contaminated water must be used for their daily activities.

Weed Harvester Restores Water Flow in Yakima River Canal During Drought

With this drought season being a rough one, the Columbia Irrigation District tried their best to do everything they could to make sure they can get all their customers the water they need. A lot of weeds are clogging up the Yakima River preventing it from flowing into a canal near the Wanawish Dam.

The warmer water temperatures made more weeds grow and the water levels this year are almost down two feet. Normally the district would spend more than $200,000 to use chemicals to clear the weeds in the canal, but they hope this new option is cheaper.

An aquatic weed harvester has been called in to cut and collect aquatic vegetation. The harvester opened channels creating more water flow. The harvester worked very well.
