Terbutryn Application


Terbutryn is a selective herbicide and a triazine compound. It is absorbed by the roots and foliage and acts as an inhibitor of photosynthesis. Terbutryn is a preemergent and postemergent control agent for most grasses and many annual broadleaf weeds in winter wheat, winter barley, sorghum, sugarcane, sunflowers, peas, and potatoes . It is also used as an aquatic herbicide for control of submerged and free-floating weeds and algae in water courses, reservoirs, and fish ponds.

The 2-chloro-s-triazine family of herbicides, widely used to control broad-leaved and grassy weeds, includes the chemicals atrazine, simazine, and propazine. Triazine herbicides have been used increasingly since the 1960s, particularly on maize crops, in North America and Europe. The estimated use of atrazine alone in the United States was almost 35,000 tons in 1993.

As a result it is found in relatively high concentrations in surface waters in certain parts of the North American continent. Triazine herbicides are relatively persistent to abiotic and biotic breakdown producing detectable levels in drinking water, foods, and fish.
Using instruction: Susceptible plants - 5kg / 100m3, moderately resistant plants - 10 kg / 100m3. Terbutryn Used pre-emergence in winter cereals at 1-2 kg a. i. / ha to control blackgrass and annual meadow grass.

Among the autumn-germinating broad-leaved weeds controlled are chickweed, mayweed, poppies and speedwell, but cleavers are rather resistant. Other pr-emergence uses are on sugar cane and sunflowers, and , in mixture with terbuthylazine, on beans, peas and potatoes. In mixture with metolachlor, used in cotton and peanuts. Also used post-emergence. (0.2-0.4 kg/ha) in cereals, (1-3 kg/ha) in sugar cane, and as a directed spray in waterways, reservoirs and fish ponds.

Terbutryn is available as a wettable powder or a soluble concentrate .

Terbutryn also used as a biocide

A biocide is a chemical substance, such as pesticides, which can be fungicides, herbicides, insecticides, miticides, or rodenticides, etc., capable of killing different forms of living organisms used in fields such as agriculture, forestry, and mosquito control.

Biocides can also be added to other materials (typically liquids) to protect the material from biological infestation and growth. For example, certain types of quats can be added to pool water or industrial water systems to act as an algicide, protecting the water from infestation and growth of algae. Even more convenient for some users are compounds such as sodium dichloro-s-triazinetrione (dihydrate or anhydrous), sometimes referred to as dichlor, and trichloro-s-triazinetrione, sometimes referred to as trichlor. These compounds are stable while solid and may be used in powdered, granular, or tablet form.

When added in small amounts to pool water or industrial water systems, the chlorine atoms hydrolyze from the rest of the molecule forming hypochlorous acid (HOCl) which acts as a general biocide killing germs, micro-organisms, algae, etc. Chlorinated hydantoin compounds have also been used as biocides.
