Meso 4SC Mesotrione Herbicide 

Active Ingredient: Mesotrione - 40%

A selective, systemic herbicide that features a new mode of action for pre and post-emergence grass and broadleaf weed control in several cool- and warm-season turf species—like keeping bentgrass out of your rough. Meso 4SC can also be applied on established or newly seeded turf.

What is the mode of action of Meso 4SC herbicide? 

Meso 4SC inhibits a plant enzyme called HPPD that is essential to photosynthesis and prevents the formation of carotenoids in susceptible plant species. Without carotenoids, light energy and by-products of photosynthesis will destroy chlorophyll and cell membranes. This results in bleaching of leaves followed by necrosis and death of the plant.

How quickly does Meso 4SC work?

Once absorbed, Meso 4SC quickly translocates throughout the plant. Weed growth is suppressed soon after application, as photosynthesis is disrupted. Death of the plant usually occurs within two to three weeks.

What turf species can Meso 4SC be applied to?

Meso 4SC can be applied to many of the turf types commonly found on fairways, roughs, or for sod production, such as Kentucky bluegrass, perennial ryegrass, tall fescue, fine fescue, centipedegrass, and St. Augustinegrass (sod only). Lower use rates are recommended for perennial ryegrass, fine fescue, and St. Augustinegrass. Meso 4SC is not for use on putting greens.

Herbi-Oil is recommended to be used with this product during hot Summer months to keep Meso 4SC from evaporating before it has been absorbed by the plant sprayed.

Usage: Apply at 4-8 fl. oz. per acre in at least 30 gallons of water.

Great for dental appliances
Color: Pink+purple
My daughter has a dental appliance that can get food caught in it. We were told to try a water flosser to get the trapped food out. This has done exactly that. Very happy with it.

Fun new way of flossing.
Color: Blue+red
My 7 year old loves it and it works really well. He’s excited about teeth brushing time again accompanied by water flosser and it can be used in the shower!

Leaks
Color: Blue+red
Water leaks out of the button you press to change out the head so we will be sending back. Other than that it would be perfect, I’m sure it’s just a fluke thing.

Almost Perfect
Color: Pink+purple
EDITED TO ADD: the seller reached out after I left this review and told me the heads are replaceable! Mine didn't come with extra heads and I didn't realize they came off. Thank for reaching out! It looks like the product even comes with replacement heads now and you can also buy them separately. Perfect! These are great. _________ My kids love these toothbrushes and I love that they're rechargeable without needing batteries. However, the charging feature is almost completely negated by the fact that you can't replace the heads! It would be a 5 star if you could swap those out.
