    How To Get Rid Of Johnson Grass in 2021

    Johnsongrass is a warm-season perennial grass weed that is hated by agricultural farmers because its presence reduces yields in corn, grain sorghum, soybean, cotton, and leguminous forages. The weed got its name from a farmer who introduced the species to his farm in Alabama in 1840s, Colonel William Johnson. Now, Johnsongrass is found in nearly every state in the country except for Minnesota and has been labeled a noxious weed in 19 states.

    Johnsongrass is native to the Mediterranean and was initially introduced to North America in 1830 as a forage crop and for stabilizing ditches. Since then, it has been an eyesore and headache to get rid of for agricultural and residential areas because of its tendency to crowd out desirable plants and destroying food and shelter for wildlife.

    A single plant of Johnsongrass can produce over 5,000 seeds which can lay dormant for up to 20 years. This weed is especially tough because it can be poisonous to cattle and horses. If you get an early frost or an extreme drought, you cannot let cattle and horses graze on any johnsongrass because it contains enough hydrogen cyanide to actually kill cattle and horses which can be a serious worry.

    Our lawn care experts have put together this guide to show you exactly what you need to remove Johnsongrass from your property permanently. Follow our step-by-step instructions below and use our recommended products to the side to be successful in getting rid of Johnsongrass.

    How To Get Rid Of Johnson Grass Organically

    If you have huge farmlands, chances are youve probably thought about how to get rid of Johnson grass organically. While there are a lot of herbicides that we can buy in the market today, using homemade ones, which are much more natural, provides more advantages compared to its chemical versions.

    If youre looking for a more organic approach to killing this pesky weed, below is a list of some of the most effective and natural ways to eliminate it and some valuable sections that will explain what the Johnson grass is and why its beneficial to use organic weed control instead.

    What Is The Lifecycle Of Johnson Grass

    Although Johnson Grass is a season perennial, in cold climates it can be an annual plant. Besides its effective dispersal techniques, this weed is prolific because seeds can remain dormant, even for 10 years, and produce plants over several years. Johnson Grass has immense seed production and a single plant can produce more than 80,000 seeds per one season.

    About 3 to 4 weeks are enough for rhizome to develop from a seed. When rhizome is established, it starts producing a large number of shoots and roots .

    When the temperature starts increasing in the spring, new-formed rhizomes and old ones which have survived the winter begin forming a large number of shoots. The flowering phase begin two months after the growth commences, and each flower panicle of Johnson Grass forms hundreds of seeds in a single flowering season.

    Seedlings grow slower than rhizomes and they need a higher temperature to germinate than a rhizome needs to produce a sprout, but both development patterns are fast enough to rapidly colonize a variety of different environments.

    What Is Johnson Grass

    Johnson Grass is a plant in the grass family , known by the scientific name of Sorghum halepense. It is a perennial plant that may reach 12 feet during a flowering phase.

    It is native to the Mediterranean region of Europe and Africa, but has been introduces to all continents except Antarctica. It was brought as a forage crop to North America and the US in 1830, but it has caused troubles for farmers, ranchers and landowners ever since.

    It was also used to prevent and stop soil erosion, but the plant showed its meany side briefly. Nowadays, Johnson Grass is considered a weed, with unflattering title of one of the ten worst weeds in the world. With the tendency to spread out at a very fast rate, Johnson Grass dominates flora and crops in a short time.

    It is most invasive in the Southeast parts of the US where its widely escaped from cultivation. In 24 states in the US Johnson Grass is even prohibited, and landowners are required to kill this highly invasive weed.

    Self-compatibility, immense seed production, effective dispersal techniques, seed dormancy and seed longevity are features which make Sorghum halepense a prolific weed.

    General Cultural Control Of June Grass

    The following crop practices help crops to compete with weeds:

    Follow the recommendations for testing the soil for the presence of fertilizer and limestone.

    • Plant high-yielding varieties adapted to climatic, soil, and field conditions.
    • Plant as soon as the soil temperature is optimal. Use small spacing between rows and large plant populations.
    • Regularly inspect weed, disease, and insect fields and inspect them as needed.
    • Rotate crops that provide early competition, such as alfalfa or small grains.

    Johnson Grass Killer Buyers Guide

    We hope that you have gone through the above list thoroughly, and that must have given you some clarity on how to choose a good Johnson grass killer.

    However, we understand that this information is not sufficient, and you might need a little more help to clear all your confusion.

    While it is essential that you know about the composition and features of the above-mentioned products, there are more things to take care of. Besides these, there are a few significant considerations to keep in mind while selecting the best weed-control herbicide for your lawn.

    In this section, we will be discussing these factors. So, without more delay, lets see what they are.

  • Rainproof

  • You must have come across rainproofing quite a few times in this guide already. It basically denotes how long it would generally take for your weed-controller to become resistant to rain.

    You must already know that rain and water are good at diluting chemicals and make them become less effective. The same can happen for a weed-killer too. If it starts raining right after you apply the product and gets diluted, you might have to re-apply very soon.

    Depending on your location, choose an option that will suit your purpose. If you stay in an area that gets a lot of rainfall, go for an option that comes with a short rainproofing period.

    In case your product does not have fast rainproofing features, do not apply it on days when there is a forecast of rain.

    Johnsongrass Control With Herbicides

    Johnson Grass Control: How To Get Rid Of Johnson Grass

    To reduce johnsongrass infestations with herbicides, it will be necessary to use an integrated approach consisting of soil-applied herbicides, postemergence herbicides, crop rotation and tillage. Weedy plants such as johnsongrass adapt quickly to a cultural system that does not change from year to year. An example of this type of system is continuous soybean production such as occurs in many river and creek bottoms. Crop rotation is important to disrupt the physical environment that johnsongrass and many other weeds live in and will help to minimize seed and rhizome production. Herbicide rotation is important to minimize selection pressure for herbicide-resistant biotypes.

    The programs mentioned below are designed to control other weeds in addition to johnsongrass. However, these programs are designed for fields where johnsongrass is not adequately controlled by current methods. For control methods to be effective, growers must be diligent and apply control techniques as often as necessary.

    In SR corn, Poast Plus or Poast HC should be applied initially to 10- to 25-inch johnsongrass. If regrowth occurs, a sequential treatment can be applied to 12-inch johnsongrass regrowth. There are no insecticide restrictions and Poast HC can be applied until corn begins to shed pollen.

    How To Control Nutgrass And Johnsongrass

    Q: What can be used to keep nutgrass and Johnsongrass out of the garden? I have tilled and used a weed block, have mulch on top and the grasses still poke through. Is there any spray that would not be harmful to the vegetable plants? -M.H., Hewitt, TXA: Sprays that would kill such weeds are either not labeled for garden use or would be harmful to vegetable plants they contact. There are, however, several options for controlling such persistent weeds, none of which is fast or easy.

    First, remember that weeds, no matter how tough, are plants. When a plant is chopped off, it uses stored energy to regrow, and then restores its reserves when the leafy tops start to collect sunlight and make carbohydrates. Any time you destroy a weed’s top and force it to regrow from stored reserves you weaken it. Repeated destruction will eventually kill it, that is, if you don’t allow it time to replenish its reserves between your attacks!

    When you mulch, try using newspaper, 8 to 10 sheets thick, covered with leaves. This will eliminate most of your weed problems. Few weeds can punch through, although they will find tears or gaps in the paper mulch. When they do, lay 8 to 10 sheets of paper over them and then some leaves to cover the paper. Remember, they can’t hold their breath forever. Just stay with it once you start!

    If you stay with it, you will win the war. Good luck! -National Gardening Association

    Selective Herbicide Applications For Johnsongrass Control

    Selective application equipment can provide economical johnsongrass control in any of the above-listed crops. Typical johnsongrass infestations are distributed unevenly across the field. Chemical costs can be reduced by using a ropewick applicator or by spot spraying the infested areas. In a ropewick applicator, mix 1 part Roundup or Touchdown with 2 parts water. Run the ropewick applicator in two directions across the field so the johnsongrass is wiped or wicked on both sides. The ropewick should be safely run above the crop canopy to avoid contact with crop foliage. Some dripping and crop injury is inevitable therefore, it is best to use a commercially available ropewick bar designed to minimize dripping.

    Spot spraying can also be an economical johnsongrass management tool. In soybean and cotton, the selective grass herbicides mentioned earlier may be mixed with water in a 1 to 2 percent solution and spot sprayed with hand wand, ATV-mounted sprayers, or tractor-mounted sprayers. Roundup or Touchdown spot sprays can also be used but will cause injury or death to crops that are not tolerant of glyphosate herbicides .
