How To Control Wild Ricewild rice

Wild rice may be a nice side dish for dinner but this aquatic plant growing on your lake or pond can be quite annoying because of how quickly it can develop and spread. Wild rice established on a body of water can choke out other vegetation and get so bad that it’ll hamper recreational activities or make it hard to sail a boat out wherever they are plentiful.

Wild rice (Zizania palustris L.) is a native aquatic plant to North America and grows predominantly in the Great Lakes region. This large-seeded species primarily grows upon lakes and have been eaten by native American tribes like Ojibway, Menomini, and Cree tribes for centuries as a staple food.

Early English explorers called this aquatic plant wild rice or Indian rice, while the French saw a resemblance to oats and called it folle avoine. Other names given to wild rice include Canadian rice, squaw rice, water oats, blackbird oats, and marsh oats. However, the name "wild rice" persisted and today it is the common name for the genus Zizania, even though the wild type of rice (Oryza) is also called wild rice.

Wild rice has always been difficult to control and if left untreated it can infest waters at an alarming rate. If you have a wild rice problem on your lake or pond, it would be wise to implement and carry out a control program before they dominate your body of water. Solutions Pest and Lawn has aquatic herbicides which can adequately take care of this plant.

How To Get Rid of Wild Rice: 3 Step Solution

When it comes to clearing away wild rice infestations from an area, there are multiple approaches you can go about doing. However, we here at Solutions Pest and Lawn believe the best method of control is the use of aquatic herbicides. If you prefer, you could use mechanical control or even physically pull them out via the root but in areas where wild rice have overtaken a body of water, this could be very labor heavy and cumbersome. Aquatic herbicides can save both time and money and is quite easy to do with the correct approach. Here are some basic steps we have laid out to control wild rices if you choose to go the chemical treatment route.

Step 1: Before applying chemical treatment, it would be wise to first inspect and analyze the body of water that will be treated for aquatic weeds. It is important to take into account the fishes and aquatic life that use the body of water as a habitat as well as the other vegetation in the water that is desirable and vital to the ecosystem. You should also determine which aquatic herbicide will be best to apply to your pond or other body of water. The size of the body of water is also an important variable which will determine how to best approach treatment of wild rice to ensure success while also making sure no fishes and desired plants are harmed.

Step 2: Once you have selected the best herbicide for you to use, you will then need to determine the right dosage and the right timing and temperature to apply the aquatic herbicide to eliminate wild rice.  Most aquatic herbicide labels give dosages on the basis of acre-feet (volume measurement). The herbicide label can then be checked for the amount of chemical to apply per acre -foot. As for temperature and timing, late spring is usually the best time to apply aquatic herbicides. This is around the time plants are young and actively growing and most susceptible to herbicides.

Step 3: Using a backpack sprayer or hand-pump sprayer, apply the selected herbicide to your pond or lake during ideal temperatures and following the instructions carefully on the product label of the herbicide you chose. If the pond is heavily infested with wild rice, it may be possible (depending on the herbicide chosen) to treat the pond or lake in sections and let each section decompose for about two weeks before treating another section. Aeration, particularly at night, for several days after treatment may help control the oxygen depletion. There is a more detailed guide on applying aquatic herbicides in our Knowledge base.
