Granular post-emergent herbicides are a great option for lawns and other areas of your yard. This is because they treat weeds that have already germinated instead of waiting until they sprout. It’s important to use granular post-emergent herbicide early in the spring when there’s still plenty of warm weather ahead so that it can work its magic before cool temperatures set in. We’ve compiled this guide so that you can learn everything there is to know about using granular post-emergent herbicide on your lawn.
Granular Post Emergent Herbicide is a post-emergent herbicide that provides control of over 200 broadleaf weeds, grasses, sedges, and woody plants on residential, commercial, and industrial turfgrass. It is labeled for use on residential and commercial lawns, sod farms, and golf courses.
Granular Post Emergent Herbicide can be used to control weeds in established turfgrass sites that have not been previously treated with any other herbicide. This product can be applied as a top dressing or incorporated into the soil depending on the desired results.
What Is Granular Post Emergent Herbicide?
Granular post-emergent herbicide is an herbicide that contains atrazine, which is a broad-spectrum herbicide. It’s used to control grassy and broadleaf weeds in corn, sorghum, sugarcane, and other crops.
It works by preventing plant cells from making proteins that are necessary for growth. When the plants’ cells are unable to absorb water or nutrients, they die because of dehydration or nutrient deficiencies.
Apply granular post-emergent herbicide before planting soybeans or other crops in fields with existing weed populations so you don’t have any competition for nutrients and sunlight once it’s time to grow your crop again later on.

Scotts Halts Crabgrass and Grassy Weed Preventer
Scotts Halts Crabgrass and Grassy Weed Preventer is a granular herbicide that kills crabgrass and other broadleaf weeds. Scotts Halts Crabgrass and Grassy Weed Preventer is a broadleaf herbicide that helps protect your lawn from weeds. It works by preventing the growth of existing weeds, but will not control established annual grasses or perennial broadleaf weeds such as dandelions, clover, and wild violets.
Bayer Advanced Crabgrass Killer for Lawns
Bayer Advanced Crabgrass Killer for Lawns is a non-selective post-emergent herbicide that controls crabgrass (and other broadleaf weeds) in cool and warm season grasses. The active ingredient in this product, 0.75 lbs. of trifluralin per gallon, works to control the growth of unwanted vegetation by blocking the production of certain nutrients needed by the plant to grow properly. This process ultimately results in cell death and plant death as well.
The best time to apply this product is when you’re seeing signs of new crabgrass growth (like tiny white flowers) or when there are already small patches of weeds growing on your lawn. It’s important not to apply this product too late though because it can take up to 4 weeks before any effects occur after application; if applied too late into summer months when temperatures are warmest, there may not be enough time left for effective absorption into the soil which could result in reduced effectiveness.

Fertilome Broadleaf Weed Control with Gallery
Fertilome Broadleaf Weed Control with Gallery is a granular post-emergent herbicide. It is effective against broadleaf weeds, but not grasses. It’s non-selective, which means that it will kill all plants it comes into contact with (including desirable ones).
When To Apply Granular Post Emergent Herbicide
The spring season is a great time to apply granular post-emergent herbicide in your vegetable garden. While there are many different types of vegetable plants, all of them can benefit from the application of granular post-emergent herbicides.
When you’re spraying for weeds, timing is everything. The best time to apply post-emergent herbicide is early in the morning when weeds are growing at their fastest rate. Weed growth slows later in the day and evening, so it will take longer for post-emergents to be absorbed and effective.
The reason for this is that post-emergents work by damaging or killing the plant cells as they absorb through the leaves, stems, and roots of the plant. This process takes time, so if you apply too late in the day or evening, then it may not have enough time to take effect before the sun goes down, thus reducing its effectiveness.
Granular post-emergent herbicides are best used when weeds are actively growing and not yet at the seedling stage. Granular post-emergent herbicide is best used:
-When weeds have just emerged from the soil surface, but before they can develop their first true leaves (cotyledons). This is usually about two weeks after seeding or transplanting into a field.
-When weeds have developed their first three leaves and are still relatively small in size, roughly one-half inch tall for broadleaf species and one-quarter inch tall for annual grasses; this usually occurs about three to four weeks after emergence.
-When most plants have developed two or three sets of true leaves; this generally takes place anywhere between five and seven weeks following emergence depending on environmental conditions such as temperature and rainfall patterns within that region throughout that time frame.
How To Apply Granular Post Emergent Herbicide
- Read and follow the label on your product.
- Use a spreader to apply the product.
- Apply when weeds are actively growing, but before they flower.
- Apply to weeds, not lawn or desirable plants; avoid applying when temperatures exceed 85 degrees Fahrenheit or when rain is expected within one hour of application.
Apply granular post-emergent herbicide in a 12- to 18-inch band, 1/2 inch deep, across the entire weed canopy.
The best time to apply granular post-emergent herbicide is when weeds are actively growing and beginning to flower or produce seed.
Wear protective clothing including long pants, a long-sleeved shirt, chemical-resistant gloves, and eye protection if working with this product will result in contact with large amounts of dust (1 teaspoon per square foot). Avoid skin contact with this product as well as ingestion or inhalation of dust particles. If exposure occurs wash thoroughly with soap and water immediately after handling this product.
How Often To Apply Granular Post Emergent Herbicide
Granular post-emergent herbicide should be applied just once per year to keep weeds from coming back. It can be applied in early spring, late spring, late summer, fall, winter, and early summer or mid-spring or midsummer.
Dosage Of Application
Dosage of Application: Granular post-emergent herbicide should be applied at a rate of 1.5 to 2 ounces per 1,000 square feet as a broadcast spray. The herbicide can also be applied using an air-assisted knapsack sprayer or boom sprayer.
The application should be made when the target weeds are actively growing but before they reach the boot stage (when their first true leaves form). It is best to use this product when temperatures are between 50 and 90 degrees Fahrenheit, although it may still work if temperatures are above 95 degrees.
This herbicide is safe for use on cool-season grasses like fescue, rye, and bluegrass as long as they are not overseeded with perennial ryegrass in late fall or early spring months before April 15th every year
Effect Of Granular Post-Emergent Herbicide On Plant
The most important thing to remember about granular post-emergent herbicides is that they are effective only when the crop has emerged. If you apply the herbicide before or during seeding, it will be ineffective. Also, note that granular post-emergent herbicides do not control perennial weeds such as quackgrass and thistle.
Granular post-emergent herbicides work by inhibiting photosynthesis in plants. This prevents them from producing the energy needed for the growth, development, and reproduction of new tissues (sinks). The biochemical pathway involved in this process is called P450 monooxygenases (cytochrome P450). It is a cytochrome-P450 monooxygenase enzyme family present in higher plants that catalyze oxidation reactions utilizing molecular oxygen or peroxide as an electron acceptor.
The best granular post-emergent herbicide is the one that you can use for your lawn. It should be able to cover all types of weeds, whether they are annual or perennial. You should also look at the effectiveness of the product and how quickly it works.
