How do you make simazine?
Simazine may be prepared in the laboratory from cyanuric chloride crystals and a strong solution of ethyl amine (at least 50 percent by number in water). The reaction is highly exothermic and is therefore best carried out in an ice bath below 10 °C.

How long does simazine last in the soil?
Simazine is a flexible herbicide as it can be used to control weeds on agricultural sites, turfgrass, non-selective weed control on industrial sites and aquatic weed control. Simazine also has an impressive residual effect of 3 to 6 months.
How do you make triazine?
The former family of triazines can be synthesized by thermal rearrangement of 2-azidocyclopropenes. Also mainly of specialized interest, the 1,2,4-isomer is prepared from condensation of 1,2-dicarbonyl compounds with amidrazones. A classical synthesis is also the Bamberger triazine synthesis.
What is the difference between simazine and atrazine?
Simazine is for grass. Atrazine is for broadleaves. Both are root absorbed so they need to be at or below germinating seed level to control a weed. If you are no-tilling, a combination of acetachlor and simazine is a very solid grass control approach.
Can you spray atrazine on switchgrass?
Glyphosate or paraquat can be applied prior to emergence of switchgrass to control weeds that have emerged. Atrazine PRE on newly seeded switchgrass on both sandy and silt loam soils to control a broad spectrum of annual broadleaf and some grass weeds.
Is simazine the same as atrazine?
Simazine belongs to the same class of herbicides as atrazine. It is widely used as a selective herbicide to control most annual grasses and broadleaf weeds before they emerge or after removal of weed growth.
Does simazine need to be watered in?
Needs 1 to 2 inches of water for optimum activity.
Is simazine a restricted use pesticide?
Simazine, a pre-emergence selective systemic herbicide, is severely regulated because of effect on humans through ground and drinking water. A U.S. EPA restricted Use Pesticide (RUP) for all land uses because of its potential to contaminate ground water.
Can you spray atrazine on Bermuda grass?
Southern Ag Atrazine Weed Killer is formulated specifically for St Augustine and Centipede grasses only and should not be used on Bermuda grass. We do carry a full line of selective herbicides of which many are labeled for use on Bermuda.
Which is the best way to prepare Simazine?
Simazine may be prepared in the laboratory from cyanuric chloride crystals and a strong solution of ethyl amine (at least 50 percent by number in water). The reaction is highly exothermic and is therefore best carried out in an ice bath below 10 °C.
What are the names of the chemical Simazine?
Simazine. . Names. IUPAC name. 6-Chloro- N, N’ -diethyl-1,3,5-triazine-2,4-diamine. Identifiers. CAS Number. 122-34-9. Y.
Which is chlorogroup is substituted by Simazine?
Simazine is a diamino-1,3,5-triazine that is N,N’-diethyl-1,3,5-triazine-2,4-diamine substituted by a chlorogroup at position 6. It has a role as a herbicide, a xenobiotic and an environmental contaminant.
How long does Simazine stay active in the soil?
It is a member of the triazine-derivative herbicides, and was widely used as a residual nonselective herbicide, but is now banned in European Union states. Like atrazine, a related triazine herbicide, it acts by inhibiting photosynthesis. It remains active in the soil for 2-7 months or longer after application.
