In this blog post, I’d focus mainly on pre emergent herbicide, the definition, weed killer, the best products that control weed and many more.
Weed being one of the most destructive enemy of a farmer contributes negative effect to the emergence of plants.
All farming space in this universe has it own weed type and there are different varieties of weed which emerge to compete with plants.
Though in the olden days when there’s nothing like herbicide or chemical substances to control or kill weed on the farmland, farmer make use of Cutlass and hoe to eliminate the growing weed.
At default, weed tends to grow on any lands where there is no foot match or where there’s free movement.
The advancement in technology has made things easier for farmer to easily control weed on their farmland.
A lot of people have been searching online to know the best pre emergent herbicide for weed killer or to control weed on the farm.

What is the meaning of pre emergent or let me say what definition can we give pre emergent?
Well as an agriculturist, I’ll be enlightening you on what pre emergent definition so you can have understanding of pre emergent herbicide.
Let’s take it from normal English language before we convert it to agricultural terminology.
We know all know “pre” means before something.. and “emergent” means emerging. That is, when something is coming into existence.
So on a literal meaning we can say pre emergent definition means before the emerging of something or before something is coming into existence. I hope you understand? That’s good!

Herbicide is regards as any formulated chemical substances that is designed to fight against weed on the farmland.
Though that one is meant for Agriculture purpose, to a layman we’d say herbicide is any substances that fight against plants.

Below are some questions and answers under this product:
Q: will it work with no pre mixing sprayer connected to water hose? if so, is setting of 2tsp for one gallon will work?
A: I wouldn’t recommend it. Prodiamine, straight out of the container, is in granular form. Each granule is about 1 mm in diameter.
All the hose end sprayers I know of require dispensing of the product as a liquid. For my application, which is to treat for Annual Bluegrass (Poa Annua) in a Zoysia lawn, I used a 3 gallon backpack tank sprayer.
I measured 3/4 Tbsp. Prodiamine and poured it into a quart container. I then added 3 cups water and mixed the two together into a concentrate.
I then poured the concentrate into the backpack tank sprayer and added water to make 3 gallons. 3 gallons will treat 750 sq. ft.
The amount to use is 1/4 Tbsp. Prodiamine per gallon of water. Each gallon will treat 250 sq. ft.
There are 3 tsp. in a Tbsp.
Q: Is this product safe for centipede grass thats 1 year old?
A: True green uses Baricade on my centipede and St Augustine lawn. It has been so successful in keeping the weeds out that I bought this (the generic version) for my planters.
