Question

Do you know of a product that will kill or slow the growth of over-seeded perennial rye grass in zoysia grass? Thank you. Ben C., AL

Answer

Everyone has questions. And BASF Professional Turf has answers.

Dear Ben: On overseeded perennial ryegrass on zoysiagrass you could use our product Image 70 DG. I do want you to know however, that the use of our product and almost any product right now as your zoysia is coming out of dormancy is not recommended. It will severely set-back green-up and could stunt the turfgrass if applied at this timing.

Control of perennial ryegrass with Image will take at least two applications and again this would not be advisable this month until full green-up. The slower you remove the ryegrass you use the lower 0.2 rate vs.the high rate of 0.26 ounces of product per 1,000 sqft. Hope this is helpful.
