Lacang grass is a type of grass weed that often spreads in fields, meadows, and other grassy areas. To eradicate them, you can use chemical, organic methods and the implementation of precautions to protect the treated area from future threats of weeds.
Step
Part 1 of 3: Chemical Herbicides
Step 1. Use glyphosate or other similar material
Since lacang is a grass, broadleaf fertilizer will not be effective against it. If you want to use a chemical method, look for an herbicide that will kill the grass. One of them that is easily obtained is glyphosate.
Glyphosate is a non-selective herbicide, so all plants in the area affected by it are eradicated. For best results, spray the entire desired area with glyphosate. While other plants will also die, this is the fastest and most effective way to get rid of weeds
Step 2. Spray several times
It's best to spray the herbicide at least two to three times to completely eradicate the weeds. Wait for the grass to reappear before spraying it again.
Wait at least two weeks before re-spraying the herbicide, especially if you are using a strong herbicide such as glyphosate
Step 3. Combine chemical herbicides with organic weed control methods
While chemical herbicides can treat most weeds, adding an organic method between sprays can help so that the eradication process will take place more quickly overall.
Approximately seven to ten days after spraying, take the remains of dead plants. If you want to improve the condition of the soil, do it now
Part 2 of 3: Organic Solutions
Step 1. Flip the ground
Dig up the soil where the lacang grass grows and turn it over so that the lacang is buried in dark, hot conditions. This way, you can slow down their growth and kill the weeds.
Do it at night, dawn, or dusk. Some argue that reversing the soil can expose weeds to bright flashes of light that will stimulate them and cause them to grow faster. If you flip the ground at night instead of during the day, you can reduce the effect of this event by as much as 78 percent
Step 2. Remove or dig up the grass
An alternative method is to remove the weeds one at a time and throw them away from their original location. Make sure you pull the whole plant up to the roots, not just the top.
- Remove the seed heads first to prevent repopulation and re-spreading in the cleared area.
- After removing the seed heads, dig into the soil under the grass using a long, slender plucking tool to reach the long roots of the lacang.
- Weeds will be easier to remove if the soil is wet and the weeds are young. The same is true for weeds.
- Remove the grass from the base if you are using your hands. Wear thick garden gloves to protect your hands.
- You can try using a weeder or lawn mower to trim the top and flowering parts of the weed. However, you will have to keep mowing again throughout the season as the grass will regrow its stems as summer continues.
- If you want to use a weeder or lawn mower, make sure you clean the blades after use to prevent accidental scattering of grass seed. Rake your lawn to remove the entire head of the sassy. With this step, it is likely that you will be able to eradicate the weed just by weeding.
Step 3. Add vinegar
If you like the ease and effectiveness of herbicides but don't want any toxic chemicals between your plants, use vinegar. Vinegar is a natural acid that is quite environmentally friendly and is known to be effective against grass-type weeds such as grasshoppers.
- USDA-labeled vinegar contains five percent acetic acid.
- Pour the vinegar directly on the grass in the ground. Try to get the vinegar as close to the roots as possible.
- Use enough vinegar to moisten the soil under the grass. The soil doesn't need to be muddy, but it should feel moist to the touch.
- Wait a week or two after applying the vinegar; observe the changes that occur. Dead or rotting weeds should be removed as soon as possible. Pour more vinegar on the grass that is still growing.
- Add more vinegar as needed.
- Vinegar tends to be more effective when used on grass that is still in seed condition. Pouring vinegar will not be very effective on mature grasshoppers.
Step 4. Use urine
You may feel reluctant to pour urine on a lawn or other area that contains plants, but it can be as effective as vinegar as a herbicide. Urine is a strong alkaline organic solution and can kill weeds as well as chemical herbicides.
- You can buy “predatory urine” products at garden supply stores. Apart from being a herbicide, the product is usually used as a repellent against small garden pests.
- A cheaper and more effective solution is to use human urine. Collect urine in a container and pour it directly on the base of the grass. Try to get to the roots.
- As with other weed control methods, urination will have to be repeated several times or in combination with physical extraction methods. Remove the weeds with your hand or a garden shovel as soon as you find them wilting.
Step 5. Apply mulch to the desired area
If the grass is still young, remove it as soon as possible by covering it with mulch. Mulch can prevent sunlight and air from reaching the weed, depriving it of the nutrients and light it needs to grow.
- Weeds should be trimmed very short before mulching.
- If there are other plants that you don't want to get rid of, spread mulch between them. Make sure the mulch is still covered with the grass.
- You can use organic mulch such as straw, leaf litter, and wood particles.
- Spread mulch about 5 cm thick.
- You can also apply a layer of black-inked newsprint under the mulch to increase its ability to inhibit growth.
Part 3 of 3: Prevention for the Future
Step 1. Try using a pre-emergence herbicide
If you don't mind using a chemical treatment, apply a pre-grow herbicide to the desired area before the grass can grow back. This is important to do if you have experienced grasshopper problems before.
- Standard chemical options that can be used include dachtal, balan, and pendimetallin.
- To try an organic pre-grow herbicide, use corn starch and protein. Spread the product when your lawn is just starting to grow to prevent the appearance of weeds and other weeds. Do not sow before your lawn begins to grow, as other grasses will also be stunted.
- Apply a pre-emergence herbicide in the spring. If you give it too early, its effectiveness may wear off. For best results, apply the herbicide once the weather has started to consistently warm. Apply a pre-emergence herbicide before the expected weed emergence period.
Step 2. Observe soil pH
The soil must be in ideal conditions for other plants. If other plants can thrive in your soil, they can absorb more nutrients to grow, so grasshoppers will have a hard time finding nutrients to survive.
- The exact pH level for your soil will vary depending on the type of vegetation you have.
- The fertilizers and other soil-fertilizing materials you use will affect the pH level. Soil fertilizers will have a greater impact on pH if they are applied to the soil instead of being spread over the surface.
- Herbicides can also affect pH. If you want to use an acidic herbicide, balance it with an alkaline one afterwards, and vice versa.
- Take your soil sample to the laboratory for pH level analysis.
Step 3. Fill your soil with other plants
If your soil is filled with plants, some of them will die once the roots start competing for nutrients and nutrients.
- You can also replace natural grass with whole grass slabs.
- In choosing plants to plant in your soil, choose dense vegetation such as legumes or hay grass. Crops that grow in rows such as soybeans and corn will leave too much space in the soil and are ineffective at stopping the growth of weeds.
- If you are planting any other type of grass in the ground, keep it as dense, green, and healthy as possible. Dense grass can help inhibit the growth of weeds.
Step 4. Keep the surface area neat
Regular mowing can keep your lawn healthy, and a healthy lawn is more difficult for weeds like weeds to grow.
While mowing is important, don't completely remove the grass. Keep the grass growing between 5 and 7.6 cm tall
Warning
- Weeds can harm cats, dogs, and other animals. For furry animals, grass can get caught and carried on to the skin to prick and cause disease or even death. For all animals, weed can get into the ears, nose and eyes. Lacang grass is also dangerous if consumed.
- Do not use the leftover grass as compost. Once you remove the weed, put it in a bag and throw it in the trash. Using grass residue as compost can cause the seeds to continue to spread and grow back.
- If you want to use a chemical herbicide, make sure your soil is not near culverts, lakes, rivers, or irrigation canals. Chemicals can cause disease in wild and domestic animals.
