Simazine a post and pre emergent? Not that effective? But cheap!
2008年1月25日 · Simazine is a good post emergent for newly germinated po annua and chickweed along with a few other broadleaf weeds. Mix it with a little bit of three-way esther when it is cold to get the broadleaf weeds not covered by the simazine. Simazine is a great pre-emergent for preventing po annua, wild onion, and chick weed.

Early results using Simazine - Lawn Care Forum
2014年11月22日 · 1 lb simazine is not enough. I got commercially acceptable weed control by applying 2 lb followed by 1 lb as detailed on the label. 1 lb might work sprayed on bare soil targeting weeds that are extremely susceptible. You are probably also seeing different results than myself because of water. Simazine is not particularly soluble.

He said 5 quarts of Simazine per 25 gallons of water which sprays exactly 2.5 acres on my rig.
Simazine question - Lawn Care Forum
2010年8月2日 · Simazine becomes a different product when tank mixed with crop oil or MSO. The oil forces uptake by leaves.

2008年10月9日 · It is true that simazine is more of a postemergent against broadleaves and goosegrass. By itself it is not that dramatic, however when combined with 2,4-D or MSMA the effect is 2+2=5. I have killed many hard to control weeds by adding simazine to the spray tank.
Atrazine vs Simizine - Lawn Care Forum
2017年10月11日 · Simazine is also well tolerated by non dormant Zoysia and Bermuda. In the past, I used it on non dormant, actively growing grasses. However, it does have slightly less of a post emergent activity on weeds vs Atrazine explained by its lower water solubility. It can also last longer as a preemergent due to that property as well.

2018年11月14日 · When it comes to Centipede I would always use Simazine over Atrazine simply because Atrazine moves more readily in sandy soils and Atrazine is a RUP which means way more record keeping for me and even requiring a fire plan for storage.
