User questions & answers

Question:	Is disease X organic
Answer:	No. It is from the strobulin class of fungicides. There are organic ways of preventing lawn disease, but most are not effective as a curative.
Question:	Should this product be put down on dry or wet grass
Answer:	With most granular applications, it should be applied to dry grass. It will need to be watered in, but only a light watering is needed. It will not need the typical .5 inches to get it watered in. The reason for this is that wet grass is the last thing you need when dealing with a disease.
Question:	What group fungicide is this
Answer:	The active ingredient is in 11. If you mix it with a fungicide from 3, like propiconizole, you have a decently resistant mixture that works well. Or rotate every 2-3 weeks.
Question:	Do you neee to water the lawn after disease ex is applied
Answer:	Yes I watered after the application.

Answer:	2.5 oz per gallon of water is the standard, recommended mix. A couple of lines down on the mixing instructions, it says you can use 1.5 oz per gallon for "weed seedlings", hence their "marketing mathematics!

User questions & answers

Question:	Will this harm my Bermuda grass
Answer:	This is highly recommended for Bermuda grass which is why I made my original purchase. Don’t put it on too heavy and don’t put it on in the hottest part of the summer. Otherwise it’s an excellent product.
Question:	Will this prevent weeds and not kill my moss
Answer:	This product does have some pre-emergent in it (isoxaben and dicamba) though it does not prevent as many weeds as something like prodiamine (sp?). Look at the label. The weeds that have the number 1 next to them, this product will kill those weeds and act as a pre-emergent to them. Here is a PDF to the product label that has a better zoom than the amazon pictures. https://images.homedepot-static.com/catalog/pdfImages/9f/9f2c6180-d51a-484b-a5a3-be86eb622b56.pdf

User questions & answers

Question:	Can I spray weed and feed directly in grass
Answer:	Jerry, If I'm understanding your question. I would only use it attached to your hose pipe as the directions indicate and if so then yes you can spray it directly on your grass. Hope this helps.
Question:	How often can i use this on my lawn
Answer:	I use it once every 6-8 weeks, no weeds and green grass!
Question:	Should this be applied after overnight temps are above freezing
Answer:	You should wait till temps are above freezing and more importantly until dandelions etc. are coming up to spray, this is after all weed and feed. If you spray before emergence of dandelions you won't kill them.
Question:	Can I spray weed and feed directly
Answer:	This needs to be connected to a hose. They do not give an amount to dilute this, as if it were other concentrated sprays.

User questions & answers

Question:	Will this kill Japanese Knotweed
Answer:	So far, it is doing great damage to my JK, but it's advised to WAIT and spray in the fall when it's in full flower. This is when the plant will carry the poison down to the root. If you spray earlier in the season when it's growing, you'll just kill the foliage and it will grow back again. I'll know more next season, but after a year and a half of failed mechanical control, this seems to be working! The hard part is waiting and letting it flourish until it flowers!
Question:	How many square feet does it kill
Answer:	John, thank you for your question regarding Roundup Ready-To-Use Weed & Grass Killer III -- with Pump 'N Go 2 Sprayer, Use in & Around Vegetable Gardens, Tree Rings, Flower Beds, Patios & More, Kills to the Root, 1.33 gal. The coverage is 400 square feet for the entire 1.33 gallon container.
Question:	how to get a better pump replacement
Answer:	I gave up on this because of the pump and cost of the ready to use solution. I went with a 1 gal Chapin 20000 sprayer and I buy the concentrate for it. Much more economical, results are as good and the sprayer is more reliable.
Question:	I followed every instruction exactly and the motor turns on, but nothing comes out. What could I be doing wrong
Answer:	That just happened to me as well. I realized in my case that the red connector wasn't pushed all the way into the top. I set the bottle down on the ground and with all my weight pushed it in and then it locked in and the chemical came right out. It had to be flush against the top of the bottle to actually come out. Hope that made sense.

User questions & answers

Question:	I am trying to kill violets in my lawn, will this work
Answer:	No. You need all kill.
Question:	Is this sold in gallon amounts
Answer:	Yes it is. The gallon size comes with its own spray nozzle.
Question:	Is this ready-to-spray or concentrate? Thanks for clarifying
Answer:	Concentrate. The instructions say that 3.2 fl. oz. (6.5 Tablespoons) of this product in 1 gallon of water treats 500 sq. ft.
Question:	does this harm lawn grass (fescue, zoysia, etd
Answer:	From my experience, the Bayer Lawn Weed & Crabgrass Killer only killed unwanted weeds. I do not have zoysia grass, so I do not know if the weed killer will kill zoysia grass or not. My guess is that if zoysia grass is tough, the weed killer should not kill it, provided you do not use more than the dosage prescribed. If you are not sure of the results, I would suggest applying the weed killer to a small area and wait a week or so to see what happens before applying the weed killer to your entire lawn.
