Comprehensive Differences Between T-Zone And SpeedZone
Learning in-depth details of both herbicides will help you learn how each product works on various weeds and weather conditions.
- Active Ingredients
Active ingredients play a crucial role in killing weeds from your lawn. Killing, controlling, and repelling pests are made by these compounds.
The SpeedZone herbicide comprises several active ingredients, including 2,4-D, 2-Ethylhexyl ester, Sulfentrazone Carfentrazone-ethyl, Dicamba, Mecoprop-P.
Since it contains several potent compounds, it can work more quickly on various weeds. That’s how SpeedZone is different than Trimec as well!
On the contrary, the main active ingredient for T-Zone is Triclopyr. It will make the weeds grow abnormal and twisted. The cell growth and division of weeds interfered through this systemic herbicide.
Additionally, T-Zone has other precise ratios of multiple active ingredients.
- Herbicide Type
The T-Zone weed killer is a post-emergent, selective herbicide that mainly destroys already grown weeds and prevents them from growing back for a particular time.
Its mixture of chemicals is ideal for applying early to late spring. Using on small but actively growing weeds kills the weeds more effortlessly.
On the other hand, the SpeedZone weed killer is mainly a highly selective herbicide. Hence, you can apply it to the targeted weed species.
This particular weed killer won’t harm the growth of nearby plants. It will only kill certain broad-leaf weeds or grass weeds.
- Target Pests
A weedkiller is mainly developed to control or kill certain types of weeds.
T-Zone can kill various kinds of weeds such as wild violet, ground ivy, black medic, oxalis, clover, spurge, speedwell, lespedeza, etc. You can get effective results by removing them from your lawn.
Contrastly, SpeedZone can destroy the growth of wild violet, dollarweed, creeping beggarweed, clover, garlic, spurge, plantain, chickweed, poison oak, ivy, and many other similar weeds.
- Particular Areas To Use
The T-Zone is safe to use in urban, suburban, commercial, and residential areas. But make sure you don’t spray them against the wind direction.
Instead of applying the whole area at a time, use it in small spaces. But you may need to apply them more heavily and frequently in residential areas.
On the other hand, SpeedZone is ideal for use on institutional, ornamental, residential sites, sod production, and noncropland areas.
Don’t apply weedkillers on too small sod. Giving it a minimum of three weeks to become long enough is a good rule of thumb. Otherwise, it will grow again after applying herbicides.
- Rainproof
Often, you need to apply herbicides during the rainy season. Applying a weedkiller during the rain will wash away the solution and affect its efficacy.
The T-Zone solution becomes rainproof after 3 hours of application. However, it may take more time during cold or windy weather. Check the leaves of weeds if they are adequately dried.
On the flip side, SpeedZone takes around 4 hours to be fully rainproof after applying it. You need to give the solution enough time so that it can be absorbed by weeds adequately.
- Weeds’ death
The SpeedZone herbicide works within 7 to 14 days. In fact, you will notice visible results within hours. Since it is highly selective, it won’t harm lawn grasses.
Getting cool weather performance from this solution is what you will appreciate.
In contrast, the T-Zone weedkiller can kill weeds within 10 to 14 days. It works a little bit more slowly than SpeedZone. But the product is effective enough to get rid of all the unwanted plants. Weeds will first start to yellow and then gradually die within two weeks.
- Coverage
Powerful herbicides generally take less quantity to cover more areas.
As per the information, 32 ounces of T-Zone can cover up to 20000 square feet.
But it can be more or less depending upon how many weeds your lawn has.
On the other hand, 20 ounces of SpeedZone can cover up to 14,000 to 18,000 square feet.
Regardless of the herbicide you use, make sure always to follow the manufacturer’s instructions to apply it in an ideal quantity.
- Cool Or Warm Season Grasses
The T-Zone herbicide is suitable for several cool-season turfgrasses. It can also kill many warm-season weeds such as Bittersweet Nightshade, Purslane, Foxtail Grass, etc.
On the contrary, SpeedZone can show reliability for killing different Cool Season Grasses such as Colonial bentgrass, Tall fescue, perennial ryegrass, Kentucky Blue Grass, etc.
Also, Some Warm Season Grasses, such as Common Bermuda and Zoysiagrass, are easy-going to destroy with SpeedZone weedkiller.
- Price
Choosing a reliable herbicide requires you to spend a decent amount of money. Compared to T-Zone, the cost of SpeedZone is slightly higher.
However, SpeedZone can cover more areas than T-Zone for the same quantity. But one thing is to remember that the efficiency of both weed killers depends on weed species and weather conditions.
