Quali-Pro® Prodiamine 4L is a professional-grade liquid pre-emergent herbicide designed to provide season-long control of many annual grassy and broadleaf weeds. Formulated with 40.8% prodiamine, this flowable concentrate helps prevent weeds from establishing by stopping newly germinating seeds before they develop.

Ideal for use on established turfgrass, lawns, ornamentals, sod farms, and Christmas tree farms, Prodiamine 4L helps control problem weeds such as crabgrass, annual bluegrass, chickweed, henbit, knotweed, foxtail, and spurge. Its low solubility and low volatility allow it to remain in the weed germination zone for extended protection. This formulation provides reliable performance with low use rates and a low-staining formulation.

Great but some shine
Size: 4 Fl Oz (Pack of 2), Style: SPF 100/Lotion, Size: 4 Fl Oz (Pack of 2), Style: SPF 100/Lotion
Sunscreen is a very important part of the skincare routine. Who cares about the results you get from the rest of your routine for your hyperpigmentation, acne scarring, etc if you aren't doing anything to protect it from the UV damage. This sunscreen offers that protection and seems to do it well which is the most important function of a sunscreen. The experience of the sunscreen for me was also positive. The sunscreen comes out white but applies clear which you would expect from an organic sunscreen. It has that stereotypical sunscreen scent but I personally love it and it psychologically ignites nostalgia for the days spent at the beach. It reminds me of the time going to the beach, making sandcastles and eating popsicles as a kid. However, I know some find this unpleasant. For those in this camp, I would not recommend this. Outside of this, however, the feel is a bit greasy at first but goes away after some time. One minor issue I find is that is does have some shine. Some people might like it but I find it is a bit much but not as bad as others on the market. In the photos you can see what it looks like before and after application. You might not be able to tell from the photos but there is some shine. Others will most likely be able to tell that you have something on. One thing I really want to point out is that this is a chemical sunscreen that uses organic UV filters meaning they are carbon containing compounds but that does not make it bad. Clean beauty brands tend to villainize these as they "contain chemicals" or are "toxic" but these claims can be highly disputable. For one, a lot of things are chemicals. Water is a chemical but you wouldn't avoid using products with that in it. Also, a company would not allow the use of actually toxic ingredients in a skincare product. There are clearly banned substances listed by the FDA that will not make their way to your sunscreen and they also protect consumers from large exposure by restricting the quantity an ingredient can be used. The heat produced from chemical sunscreens are also minuscule compared to that of physical (or inorganic) sunscreen. These are just a couple of reasons that chemical sunscreens are very much safe (as far as we know it) according to science. I'm sorry for the small rant. I know that most of the people who see this review are looking at it because they know chemical sunscreens are not the devil as they are looking at this product but I was hoping to dissuade people who adhere to the clean beauty methods from being swept up from the fear-mongering marketing.

good spray, but strong alcohol smell
Style: SPF 50, Size: 5 Fl Oz (Pack of 1)
I like Alba Botanica, but 3.5 starts since: - the spray goes way too fast (that can be true for all continuous sprays). I used it 4 - 5 times and it seems I have very little left. - lots of waste when spraying... probably is best to spray your palm and then massage it on your body - once it's sprayed it smells like alcohol, alot!!! Other brands I tried don't seem to smell so much of alcohol. - My kid developed strange rash once it was applied, not red dots, but white bumps all over the arms and legs, cannot say its from this spray, but I'm a bit suspicious. The good party it's it is not sticky or greasy. Smells good (after alcohol evaporates). I used it a couple of times, applied once only and stay several hours under the sun and I was fine, no sunburn.
