What is triazine used for?

What is triazine used for?

It is used in livestock, vegetable, and ornamental applications by interfering with insect molting and pupation. As herbicides, the triazines may be used alone or in combination with other herbicide active ingredients to increase the weed control spectrum. They are inhibitors of electron transport in photosynthesis.

Which herbicide belongs to triazine?

Some triazine herbicides are listed below: Atrazine (2-chloro-4-ethylamino-6-isopropylamino-1,3,5-triazine) Propazine. Simazine (2-chloro-4,6-bis-ethylamino-1,3,5-triazine)

Is triazine hazardous?

– Triazines are mild skin irritants and can be highly irritating to the eyes. LONG-TERM HEALTH HAZARDS – The Federal Environmental Protection Agency considers triazines as possible human carcinogens.

Where is triazine found?

Among herbicides, the chloro-s-triazine derivatives, and atrazine in particular, are the most heavily used worldwide, and are often therefore, detected in rivers, lakes and groundwater [6].

How is triazine made?

The more common 1,3,5-isomers are prepared by trimerization of nitrile and cyanide compounds, although more specialized methods are known. The 1,2,3- and 1,2,4-triazines are more specialized methods. The former family of triazines can be synthesized by thermal rearrangement of 2-azidocyclopropenes.

Is triazine water soluble?

By increasing the temperature of the water, the solubilities of the triazine pesticides increased approximately 3-fold in pure water for each 25 degrees C temperature increment. Cyanazine was 5 times more soluble than atrazine and an order of magnitude more soluble than simazine at 100 degrees C.

What are organochlorine pesticides used for?

What are ORGANOCHLORINE PESTICIDES? Organochlorine pesticides are chlorinated hydrocarbons used extensively from the 1940s through the 1960s in agriculture and mosquito control.

Is metribuzin a triazine?

Metribuzin, an asymmetrical triazine, is used on a limited basis in bermudagrass turf, mainly combined with either monosodium methanearsonate (MSMA) or disodium methanearsonate (DSMA) for postemergence control of goosegrass.

How does triazine scavenger H2S?

Triazine is also preferred in situations where the acid gas stream contains high levels of CO2 in addition to H2S. The triazine reacts preferentially with the H2S and the reaction is not inhibited by the CO2, avoiding unnecessary chemical consumption.

How does triazine affect photosynthesis?

Mode of s-Triazine Action s-triazine herbicides act by inhibiting primary events in photosynthesis in the chloroplast: binding to the D-1 protein in photosynthetic electron transport. This binding stops photosynthesis.

How do you make MEA triazine?

MEA-triazine is produced by mixing stoichiometrically equal amounts of monoethanolamine and formaldehyde. Three molecules of MEA plus three molecules of formaldehyde produced one MEA-triazine molecule and three molecules of water.

Why are organochlorine pesticides banned?

Although these compounds were widely used in the 1940s in large quantities, they were banned in developed countries in the 1970s because of their high persistence in the environment and their harmful effects in human health.

What is triazine herbicide?

Triazine herbicide is a kind of broad-spectrum herbicide with the basic chemical structure of triazine. Based on whether the N atom is evenly distributed in phenyl ring or not, it can be divided into even triazine and non-even triazine, two categories.

Is atrazine a pesticide?

Atrazine is a very popular compound and as of 2014 was the second most widely-used herbicide in the United States, even though it has been the subject of controversy due to concerns about its toxicity and environmental effects. What about a triazine pesticide that contains sulfur?

How many insects does Spectracide Triazicide kill?

What plants are resistant to triazine?

The strongest drug resistance to the triazine herbicide has been observed in corn, millet, sugar cane and apples, grapes. Some varieties of sorghum, carrots, celery, potatoes, cotton, sunflower, peas and soybeans also have strong resistance to them.
