13 best herbicides

Herbicides, commonly known as weed killers, are chemical or biological substances used to control, manage, or eliminate unwanted vegetation, commonly referred to as weeds. These products are commonly used in gardening, lawn care, and agriculture to maintain the health and appearance of lawns, gardens, and agricultural fields. Here's what you need to know about herbicides:

  1. Types of Herbicides:

    • Selective Herbicides: These target specific types of weeds while leaving desirable plants largely unaffected. They are commonly used in lawns and gardens.
    • Non-Selective Herbicides: These kill or damage a wide range of plants, including both weeds and desirable plants. They are often used for total vegetation control in areas like driveways and sidewalks.
    • Pre-Emergent Herbicides: These prevent weed seeds from germinating and establishing themselves in the soil.
    • Post-Emergent Herbicides: These are applied to existing weeds to control or eliminate them.
  2. Mode of Action: Herbicides work through various mechanisms, such as inhibiting plant growth hormones, disrupting photosynthesis, or interfering with cell division. Different herbicides have different modes of action.

  3. Application Methods: Herbicides can be applied in various ways, including spraying, spreading as granules, or using specialized applicators. The choice of application method depends on the type of herbicide and the target area.

  4. Timing: Timing is crucial when using herbicides. Pre-emergent herbicides are applied before weeds appear, while post-emergent herbicides are applied after weeds have grown.

  5. Safety: Herbicides should be used with caution, as they can be harmful to humans, pets, and the environment if not used properly.Always follow the manufacturer's instructions for safe handling and application.

  6. Environmental Impact: Some herbicides can have adverse effects on the environment, including soil and water contamination. Environmental regulations and guidelines are in place to minimize these impacts.

  7. Resistance: Prolonged use of the same herbicide can lead to weed populations developing resistance to it. This necessitates the rotation of herbicides with different modes of action to maintain their effectiveness.

  8. Weed Control Strategies: Herbicides are just one component of weed control strategies. Integrated weed management also includes practices like mulching, mowing, and manual weeding to reduce the reliance on chemicals.

  9. Licensing and Regulations: In many countries, the sale and use of herbicides are regulated. Licensing may be required for their purchase and application. Always adhere to local regulations and guidelines.

  10. Commercial and Home Use: Herbicides are available for both commercial agricultural use and home gardening. Home gardeners should select herbicides designed for residential use and follow label instructions carefully.

In summary, herbicides are chemicals or biological substances used to control or eliminate unwanted weeds in various settings, including gardening, lawn care, and agriculture. They come in different types and have specific modes of action. It's essential to use herbicides safely and in accordance with regulations, considering their potential environmental impact and the development of weed resistance.

User questions & answers

Question: I was planning to drill holes in some fresh cut stumps and inject this to kill the roots. Will that work
Answer: Yes it will kill stumps you have to put it on right after cutting the tree. You don't have to drill holes, "paint" it on the cut part of the stump full strength. I have been doing this for years. This is essentially like spraying the leaves, (for the post emergent guy).
Question: how long does it kill the vegetation for? I am contemplating this or the ortho total vegetation killer that lasts 12 months. Is this better than the o
Answer: Haven't used Ortho's product. We have a pond fed by run off, lot's of wild life and pets so we opt for some amount of "touch up" spraying mid summer if we get some late rains. We like the Glyposate environmental safety record so far, and feel it's worth the effort.
Question: What is the manufacturer's recommended dilution Ratio
Answer: Go to the Ranger Pro Herbicide website and download PDF file for dilution instructions
Question: How long is this effective? If I apply how long after can I plant/grow brassicas cow peas, soybeans etc
Answer: highly effective, equivalent to ingrediants in round up.. you should read instructions on when you can replant. this is the pro strength at 41%. round up over the counter i think is 19%

User questions & answers

Question: Does it kill stickers
Answer: ARE YOU TALKING ABOUT GOATHEADS OR GRASS BURS? THERE ARE BETTER AND CHEAPER THAN REMEDY. ROUNDUP?
Question: I purchased this to kill weeds, so what is the best solution in a 21 gallon tank? how much remedy to water or should i add water remedy and diesel
Answer: I bought it to kill that nasty mesquite that plagues my ranch in east Texas. I used 24 oz. with 104 oz. of diesel in a 2 gallon container for each spraying. That 20 percentage is probably way too strong, but it effected the stalks I sprayed in about three days. The leaves turned from bright gree to yellow as they wilted and the plants were quite dead in a few weeks. That mesquite is quite hardy, so I would think you can use Remedy in the percentages as recommended for lesser plants.
Question: Is this effective for large trumpet vines and do I just mix with diesel fuel and paint cut stumps
Answer: Trumpet Creeper is listed as a plant controlled on the Remedy Ultra Label. It suggests that for this weed to use basal or dormant stem applications only. It continues on page 7 of the label about specifically how to apply treatment. Triclopyr, the active ingredient in Remedy Ultra is one of the more effective ways to control this type of vine. Thank you for considering making your purchase from AgCare Products and AgCareDirect via Amazon. Feel free to contact us directly if you need more assistance in how to spray if we can be of service.
Question: How to mix for weed/vine
Answer: We use it at 1/4 remedy to 3/4 diesel fuel and it is very effective

User questions & answers

Question: Why would "AG" not include "sufactant" into their hercercides? Why must customers buy a separate product to make their herbicide more effective
Answer: You would have to ask the company that question. Tablespoon or two of Dawn dishwashing liquid works fine or another brand of your choice. Surfactant (soap) will cause the product you are using to stick and stay on the weed leaves or blades longer producing a better kill.
Question: I want to kill sumac - lots of it. i am using trichlorpyr 4 do i use this stuff and water? and if so, what mix in a 2 gal sprayer
Answer: Sumac like poison ivy its cousin is a woody plant and typical weed killer (broadleaf, crabgrass etc) won't work. I use Round-up's poison ivy specific formula and it works great. Cheaper is Brush-B-Gone which you buy and mix from the concentrate yourself. Both are very effective against these nasty poison ivy family thins. Just be very careful about overspray-- it will absolutely kill adjacent plants you may want.
Question: how much do I mix per gallon of herbicide/water
Answer: I purchased the surfactant product to use with Drive XLR8 Herbicide. The mixing volumes for the surfactant and herbicide per gallon of water are listed in the label directions. As I recall, the surfactant amount was 1 ounce/gallon and the herbicide was 2.5 ounces/gallon. You should google the surfactant product and check for a volume listing. Good luck!
Question: what does surfactant do
Answer: Surfactant allow the liquid it's mixed with to stay on the surface of the water on the algae. Liquid soap does the same thing, but tends to develop suds.

User questions & answers

Question: How long before you see results? I used it on an end of hose sprayer, and not seen a change in 2+ weeks. Thx
Answer: You will need to spot treat the weeds as well before seeing results. Use a one gallon hand pump sprayer with a few glugs of the chemical, then fill the rest with water. Good luck!
Question: can I use it in an area behind my garage that has poison ivy
Answer: This will work well with most broadleaf weeds, including poison ivy. Watch in a few months: Poison ivy has a strong root system that might survive first application of herbicide. Glyphosphate will do the job too. It will kill anything green.
Question: I understand that this product is also recognized as being "Agent Orange
Answer: It was half of the concoction. The other was 2,4,5-t which is now a restricted use product and can only be bought with a license.
Question: Is this product safe for use on St. Augustine lawns
Answer: 2, 4-D is a generic broad leaf weed killer found in almost all broadleaf herbicides. Since St. Augustine is a grass (and not a broadleaf), 2,4-D will not kill it. However, if used again and again in a particular location, it will eventually kill the St. Augustine which is what I experienced in a small patch which had oxalis (yellow sorrel) weed. I later found out from Texas A&M that oxalis, albeit a broadleaf, is very, very hard to kill since it has underground rhizomes which regenerate the weed even if it appears to have been killed. Their recommendation for a broadleaf weedkiller a homeowner could use (i.e., you don't have to have a applicator's license) was $64.99 for 2 ozs, so I passed. Think I'll try to hand dig my oxalis.

Question: Is this safe to mix with Cimarron Plus for horse pastures? If so, what is the wait period
Answer: There really isn't much for directions other than to say it is for"most herbicides". It does mention 2-4D and brush killer. It mixes at a rate of 1/2 to 2 teaspoons per gallon depending on the type of herbicide.
Question: Can this be used with drive xlr8? if so how many tablespoons per gallon do i use
Answer: Drive xlr8 recommends a methylated seed oil for use as a surfactant. This surfactant is basically a soap.
Question: Can this be used to kill prickly pear cactus? i have a bunch in my yard. i live in az
Answer: only if you put some weed killer of some kind in with it. I too live in Arizona. Cacti are best eradicated with just a shovel, they have very shallow root systems and are easy to up-root. You have to deal with the dead ones either way, if you spray them or dig them up. best to burn them in a barrel, load them with a pitchfork.
Question: Can this be used with selective herbicides for lawn applications? Will it harm the grass
Answer: The surfactant will not harm the grass itself. It's purpose is to create a "wetting" effect for the herbicide to surface of the plant. This allows the herbicide to fully work for it's intended purpose.

User questions & answers

Question: Is this product safe for a home lawn? The product description says it's for farm use only, but I have creeping buttercups overtaking my lawn
Answer: If used according to directions, it's safe for lawns. I've used it on mine and while I don't have kids, I do have dogs. You do have to be careful to keep the spray away from trees and shrubs. Milestone is designed to kill broad leaf vegetation which includes most trees, but it does not kill grass. The toxicity is very low; Milestone is the only herbicide I know of that does not require any precautions for use around livestock (and I am very careful about using herbicides around my horses). However, unless you have a very large lawn, you may find it too expensive. When correctly diluted, one bottle goes a long, long way.
Question: Do you need a license to purchase this
Answer: The product says it is not restricted, but my Cornell Coop representative has notified me that in NY a license is required. He was surprised I had obtained the product.
Question: will it kill canadan thistle. should i use 2oz. for a 15 gal. sprayer
Answer: Does a great job killing Canadian thistle. I use 7ozs for my 24/25 gal tank. I also spot spray with Weed B Gone on Canadian thistle
Question: Will the residual in the ground from this product prevent my fescue seeds from germinating
Answer: Milestone label does not list a particular waiting period following use, for seeding grasses. Fescue is generally one of the most vigorous grass plants and the inquirer shouldn't have a problem. The rule-of-thumb is to wait a couple weeks before reseeding grasses, following broadleaf herbicide spray.

Question: Is this Triclopyr 4 effective on cedar trees? If so what surfactant is best and mix rate
Answer: I love this stuff. I have found that it is great on all kind of bushes and trees that are normally resistant. I mixed 2 ounces per gallon of water, about 2 ounces of 24D and add some dishwashing liquid for surfactant
Question: What is the mixture to use in a hack and squirt method to kill Ailanthus? I read between 1:1 to 2:1 i.e 30%-20% concentration. Advice
Answer: First I would suggest google "specimen label for Triclopyr" A 25% to 30% mix with an oil product...see label. will kill most everything.

Its active ingredient, mesotrione, is based on a naturally occurring compound produced by the bottlebrush plant (Callistemon citrinus) that inhibits photosynthesis in susceptible plant species.

User questions & answers

Question: How much lawn will this 8oz bottle cover? We have .3 of an acre
Answer: The 8 oz bottle will produce 96 gallons of solution using 1/2 teaspoon per gallon of water. I forget what the coverage is but it will certainly cover .3 acres using a pump sprayer.I have been using mine on my .5 acre for two years and I have only used about 1/3 of the 8 oz.
Question: Anyone know how tenacity compares to a product called "dismiss"? i have some nutsedge to get rid of and i'm trying to decide which to get. thanks
Answer: tenacity is labeled for nutsedge. . Dismiss is the the better choice, however. Usually with tenacity, you have to apply it at least two to three times, at two week intervals. They are both broad spectrum. Tenaciity's claim to fame is its ability to kill grassy weeds, like Nimblewill. They are both labeled for Goose grass. I don't think Dismiss is labeled for Nimblewill. PS: spectricide makes a good 4 way for the home owner. It has 24d, dicamba, quinchlorac, and sulfantrazone (dismiss). spelling. they sell it on amazon and lowes.
Question: can i apply over
Answer: The official answer is no for most herbicides. Depending on what you're trying to control. Here is a link to one of the best reports I have found - http://archive.lib.msu.edu/tic/golfd/article/2012oct33.pdf. This report shows great results with mid-80 degree temperatures in the control of POA ANA (Which is what I'm challenged with controlling). The general rule of thumb with Tenacity is the higher the temperatures the more applications (small dosage) needed for control. Tenacity has a half-life of 5-15 days depending on the temperatures - the higher temperatures the lower the half-life. The report and other reading also indicates that Tenacity needs to stay in the plant at or above the half life levels for ~ about 14 days or so to gain a high level of control. My advice would be to look for a week when temperatures are expected to average below 90 degrees and make a couple applications during that week and observe the control that you achieve - then goo from there. I experimented for a couple seasons using this report to get a feel for the best application frequency, rates, temperatures and timing (time of year). I hope this is helpful. Good luck and all the best.
Question: what is surfactant? Is it included with tenacity
Answer: A surfactant is a separate product that you add to your applicator tank. It helps the Tenacity stick to leaf blades and better kill the weeds. I used Bonide Turbo spreader sticker. It, or something similar is available in small bottles in garden centers. The ratio I used for nimblewil was 1 teaspoon of Tenacity and four teaspoons of surfactant per 1 gallon of Water.

User questions & answers

Question: Does this product come with the measuring syringe
Answer: Yes it does, but it’s very hard to read when filling and it’s cheap, I would plan on a measuring cup or something else
Question: Is Tenacity safe to use on cenipede grass
Answer: I put it on mine and it seemed to do okay. Just be careful and get the blue dye that is sold with it so you can see the application you put it on. Only go over the area one time where you are trying to kill the weeds. There are some 'youtube' videos that explain how to use this in case you are not aware of them.
Question: Why is this vender so overpriced
Answer: Tenacity is a professional product. If you can find Tenacity at a better price, go for it. It's not overpriced here... It's just not cheap anywhere.
Question: Does this work on clover
Answer: Yes it does. There is a You Tube tutorial about this product and how to use it. Look up Silver Cymbal, a yard guy.
