Product Overview
Hi-Yield Killzall 365 is specially formulated to provide total vegetation control for up to one year. It contains powerful active ingredients which helps kill and prevent new weeds and unwanted grasses from growing on treated areas whole year round. It is designed for use on non-crop areas like parking lots, driveways, sidewalks, gravel areas, and around fencerows and buildings. It is guaranteed rainproof within an hour so rain or watering will not wash away effectiveness easily. It is recommended to be applied to bare soil to get the longest residue or generously spray nuisance weeds and grasses to get both good control and long-lasting residue. Make sure to avoid spraying under or near desirable plants including trees and shrubs to keep them from dying. A 32 oz. bottle treats up to 4,300 sq. ft.

Apply on a sunny day with temperatures above 60 degrees Fahrenheit. Avoid product runoff to nearby desirable plants. In soils with heavy clay, weed control may exceed one year.

(0.46 pints) of this product with water to produce 1 to 10 gallons of spray solution. Optimum performance will be achieved from applications to actively growing weeds in early summer.

So far it's been only 2 months, but this product has definitely managed to kill all vegetation in the applied area and they are still very much dead :) Was easy to mix and apply as well.

8 Questions & Answers
Helpful Q&A'sQThe mix instructions are very vague for Hi-Yield Killzall 365How can you get the same effectiveness with instructions like. "Mix 7.4 fl. oz. (0.46 pints) of this product with water to produce 1 to 10 gallons of spray solution". I am no chemist, but these instructions are not useful at all, how can mixing the same quantity in 1 gallon be as effective as mixing it in 10 gallons? What is the correct mix rate for a bare ground application?AFor the Hi Yield Killzall 365 the mix rate and water volume used is based on the density of the weeds you are treating and the size of the area being treated.

Read Full Answer »For the Hi Yield Killzall 365 the mix rate and water volume used is based on the density of the weeds you are treating and the size of the area being treated. If weeds are small and young, a lower amount of water would be needed to get sufficient coverage. Whereas if you have tall dense weeds that are mature and more well established, a higher water volume would be needed to get the product to cover the entire surface of the treated area and not just the top foliage. The product label goes on to say in the paragraph below the one you are referencing, that this indicated volume should be used over 1000 sq/ft. If you were to use 7.4 oz over 1500 sq/ft for instance, you would not get the same result as you would have spread the product too thinly. You can see our video below explaining why calibrating your sprayer and figuring out how much water volume you specifically will need for your individual treatment area is important to help you know how much solution to mix with water. Please review our video here for how much product per gallon/calibrate your sprayerQHow safe is Hi-Yield Killzall 365 for cats?AHi-Yield Killzall 365 is safe for pets if used correctly.
