Oryzalin 4 Pro 32oz- Pre-Emergent Herbicide

This stuff works! You have to time the application pretty good to increase its effectively. I'm in Dallas and I apply it in late September for the wall/winter weeds and late February for the spring/summer weeds. It really cut down on the amount of weeds that we've had over the past year. Yes, not 100% of the weeds are gone but it really worked. We probably knocked out about 90% of the weeds that we used to have just using Scotts weed and feed turf builder. This stuff really works, just apply it at the right time.I mix it at 1.5 oz/gallon. I apply 4 gallons for my 60x120 lot. Hopefully this is helpful, I know I'm glad that I ran across this product.

The advertising is confusing in my estimation when it states " Oryzalin 4 Pro Pre-emergent Herbicide Equivalent to Surflan AS 1 Quart". I had used Surflan and now have used Oryzalin. They both work extremely well and the Oryzalin has done everything I expected of it. My only criticism, and perhaps this is my fault, is I thought I was getting the "Herbicide Equivalent to Surflan AS 1 Quart." The actual amount is 8 ounces. The Oryzalin controlled my weeds and nothing new is coming up. Leaves a light reddish tinge to the yard but wears off in a couple of weeks. Works exactly as advertised and I would recommend it. Just don't expect a quart.

have used this stuff for years - you just can't beat it for weed control inside flower beds - also, I really dig the new bottle that has integrated one ounce measure cup - just squeeze the bottle and it fills the measure cup - no muss, no fuss :)

Spray this three times a year and you'll new have weeds. It will stain cement sidewalks if mixed to strong.

worked fine, trick is to put it on at the right time of year.

seems to be working great to control my weed seeds from germinating

Great buy. Just as described. Arrived on time.

Worked well
