How To Control Torpedograsstorpedograss

Torpedograss may be an annoying and noxious weed that can grow on lawns and has long frustrated home owners but they can also grow on bodies of water and ugly up ponds and lakes as well as make it a headache to enjoy recreational activities like fishing and swimming. Torpedograss grows in or near shallow waters forming monocultures where it can quickly displace native vegetation. It can also be found in more upland situations and is a frequent problem for farmers by interfering with sod production. Whether on land or in water, this weed can be tough to get rid of without a well thought-out plan.

Native to Asia and Africa, Torpedograss made its way to the United States initially as a forage crop. In the early 1900’s the United States Department of Agriculture imported and distributed torpedograss seed for planting in pasturelands, providing forage for cattle. Torpedograss is from the Poaceae family which includes grasses such as cogongrass and bermudagrass. They are named torpedograss because of the sharply pointed growing tips which resemble torpedoes.

Torpedograss can grow up to 3 feet tall, with hairy leaf sheaths and hair on the upper margins of the leaves. Leaf blades are stiff, linear, flat or folded; the surface often with a waxy or whitish coating. Torpedograss has a panicle-type inflorescence, 3-9 inches long. The spread of torpedograss is limited to rhizomes either by rhizome expansion or fragmentation. They mainly are prevalent in the southeastern United States, particularly in Florida.

If your aquatic property is suffering from an invasion of torpedograss, Solutions Pest & Lawn has all that you need to effectively remove them completely so they are no longer a problem.

How To Get Rid Of Torpedograss: 3 Step Solution

When controlling aquatic weeds, especially one a difficult and stubborn to control like torpedograss, there are not many options you can take which are effective. Some people may take the manual route and physically remove the weeds. However if you have a particularly large outbreak of torpedograss where they have heavily overtaken your pond or lake, physical control may be too big of a job to carry out by hand. At Solutions Pest and Lawn we have aquatic herbicides which you can use to kill off torpedograss and discourage growth. Below we have laid out a 3 step plan where if followed closely, you can easily eliminate torpedograss.

Step 1: All chemical control treatments should start with a careful inspection. Survey your lake or pond and determine what the best and safest plan of option there is to take. You have to take into account how the lake or pond is utilized not only by humans but also the fishes and aquatic life which inhabits the water. Asking yourself these questions and weighing the pros and cons of control before proceeding is a highly recommended first step.

Step 2: Once you have carefully analyzed your pond and lake, you can than move on to selecting a treatment method to manage the torpedograss growth. At Solutions Pest and Lawn we have a large selection of different aquatic herbicides which come in both liquid or granular forms. Liquid herbicides are a great solution because they attack weed growth in shallow water on or above the ponds surface and can be spread evenly with a pump sprayer. This makes the control process efficient and convenient to physical removal.

Granular herbicides are also an excellent selection especially when weeds are submerged as blankets under the water surface in deep areas of the pond or in ponds with flowing water. These heavier granules can be applied with a hand spreader and will sink directly onto the weed beds. What you select is entirely up to your personal preference. You will see our recommendations below.

Step 3: Apply the 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. Depending on the size of your pond or lake, you may need to conduct treatment in sections rather than all at once. Apply the herbicide to an area, possibly in thirds and wait 2 weeks between treatments until you’ve treated the entire body of water. There is a more detailed guide on applying weeds in our Knowledge base.
