Celsius Herbicide Application

A herbicide is a chemical that kills or controls unwanted plants, such as herbs. Farmers and gardeners can use herbicides to protect their crops and clean their gardens. Some herbicides kill all plants, while others target only certain types. They can be sprayed on leaves or applied to the soil. Too much herbicide use can harm the environment, so people must use them carefully.
Celsius herbicide is a herb killer that controls unwanted plants in warm-season grasses, like those found on lawns and golf courses. It is effective against many broadleaf and grassy herbs and works even in hot weather. This herbicide is popular because it does not harm most common turfgrass types while killing herbs.
Celsius Herbicide Application works best in warm climates, making it popular for regions with warm-season grasses such as Bermuda, St. Augustine, and Zoysia grass. Gardeners can buy it from Growcycle to keep their lawns healthy and herb-free.
Key Ingredients of Celsius Herbicide
Celsius herbicide is designed to kill herbs while keeping the lawn safe. Here’s how each ingredient works:
- Iodosulfuron-methyl-sodium: This ingredient stops herbs from growing by blocking a key process inside the plant. Herbs need unique proteins to grow, and this chemical shuts down the system that makes those proteins. Without them, the herb eventually dies.
- Thiencarbazone-methyl: This also works by stopping herbs from making proteins. It enters the plant’s system and prevents it from getting the nutrients it needs to survive. Over time, the herb starves and dies.
- Dicamba: This ingredient works differently. Instead of stopping protein production, dicamba acts like a plant hormone. It makes the herb grow weirdly and uncontrolled, eventually killing it. It spreads through the herb’s leaves, stems, and roots to ensure the whole plant is affected.
These three ingredients target many common herbs, including broadleaf and grassy, without harming warm-season grasses like Bermuda, St. Augustine, and Zoysia.

Benefits of Celsius Herbicide
It is an excellent choice for controlling herbs in warm-season lawns as it is safe for the grass and works well on many different herbs. Here are some benefits of this herbicide:
- Broad Spectrum: One of the most significant benefits is that it controls various herbs. It is designed to kill both broadleaf herbs (like clover and dandelions) and grassy herbs (like crabgrass). Many herbicides only work on one type, but Celsius covers both, making it more effective.
- Safe for Warm-Season Lawns: Many herbicides can harm grass and herbs, but Celsius is specially made for warm-season grasses like Bermuda, St. Augustine, and Zoysia. It can be sprayed on the lawn without damaging the grass.
- Works in Hot Weather: Some herbicides lose effectiveness in high temperatures, but Celsius works well even in hot weather. This makes it perfect for lawns in warm climates where herbs grow aggressively in summer.
- Long-Lasting Effects: Celsius herbicide kills existing herbs and helps prevent new ones from growing. It stays in the soil for a while, reducing the chances of herbs returning quickly. Its long-lasting effects save time and money.
- Easy to Use: It is easy to mix and apply. A small amount can be mixed with water and sprayed directly on the herbs. Unlike some herbicides, which require complicated application methods, Celsius herbicide is simple and convenient.
- Moves Through the Whole Herb: It is highly effective because it moves through the entire plant, not just the leaves. The herb absorbs it and spreads to the roots, killing the whole plant. This makes it more effective than herbicides that only burn the leaves but do not kill the roots.
- Reduces herb Resistance: Some herbs resist herbicides over time, making them harder to kill. Celsius herbicide contains three active ingredients that work together to make it difficult for herbs to become resistant.
- Minimal Damage to the Environment: It is designed to target herbs while being safe for the surrounding environment. It does not have harsh chemicals that can harm beneficial plants, and it breaks down naturally over time, reducing the risk of long-term soil damage.
Celsius Herbicide Application
Applying Celsius herbicide is easy, but using it correctly is essential to get the best results. Follow these simple steps to ensure lawn safety.
1. Preparation
Before herbicide application, make sure to have:
- Celsius herbicide
- A sprayer (handheld, backpack, or pump sprayer)
- Measuring spoon or scale
- Water
- A pair of gloves for safety.
2. Choose the Right Time
For the best results, apply Celsius when the temperature is between 60–90°F. It works well in hot weather, but avoid spraying in extreme heat (above 95°F). Spray on a dry day with no rain expected for at least 24 hours. This allows the herbicide to stick to the herbs. Apply when the grass and herbs are dry.
3. Mix the Herbicide
Measure the correct amount of herbicide according to the area of the lawn. Fill the sprayer halfway with clean water. Add the Celsius herbicide to the sprayer. Stir or shake the sprayer to mix well. Add the remaining water and mix again.
4. Spray the herbs
Adjust the sprayer nozzle to a fine mist. Hold the sprayer about 12 inches above the herbs. Spray directly on the herbs until the leaves are lightly coated but not dripping. Do not spray on flowers, vegetables, or other desirable plants.

5. Be Patient
herbs will start turning yellow or brown within 7 to 14 days. Some tougher herbs may take 3 to 4 weeks to die completely. Do not mow for at least 2 days after spraying. This gives the herbicide time to work. Apply another treatment if herbs grow after 4 to 6 weeks.
6. Clean the Equipment
Empty any leftover herbicide from the sprayer. Clean the sprayer three times with fresh water. Wash hands and any tools used.
FAQs
What types of herbs does Celsius herbicide kill?
Celsius herbicide kills over 150 types of herbs, including broadleaf herbs like clover, dollar herb, dandelion, and chickherb, and grassy herbs like crabgrass and foxtail.
Can Celsius herbicide be used on newly planted grass?
Avoid using Celsius on grass less than 3 months old or recently sodded, seeded, or sprigged. It may stress the young grass.
Can a surfactant be added with Celsius herbicide?
Adding a surfactant (such as a non-ionic surfactant or dish soap) can help the herbicide stick better to herbs, making it more effective. It is not required, but it improves results.
