Highly Effective Cyhalofop-Butyl + Bispyribac-Sodium

Cyhalofop-butyl ten% + Bispyribac-sodium ten% OD

Cyhalofop-butyl NOMENCLATURE
Typical title cyhalofop (BSI, E-ISO, (m) F-ISO, ANSI, for the carboxylic acid) 
IUPAC name butyl (R)-2-[4-(4-cyano-2-fluorophenoxy)phenoxy]propionate
Chemical Abstracts identify butyl (R)-two-[four-(4-cyano-two-fluorophenoxy)phenoxy]propanoate 
CAS RN [122008-85-9] [122008-seventy eight-] acid 

Cyhalofop-butyl Purposes
Cyhalofop-butyl Biochemistry Fatty acid synthesis inhibitor, by inhibition of acetyl CoA carboxylase (ACCase). Selectivity in between prone grasses and dicotyledonous vegetation is attributed to the kinds of ACCase current and their compartmentalisation in plant cells. Prone grasses have the vulnerable eukaryotic kind of ACCase dicotyledonous crops include equally inclined eukaryotic and herbicide-resistant prokaryotic kinds of ACCase, rendering them resistant to cyhalofop-butyl. Rice tolerance to cyhalofop-butyl is due to quick fat burning capacity to the herbicidally inactive diacid (DT50 <10 h), whereas susceptible grasses metabolise cyhalofop-butyl to the herbicidally active monoacid.

Cyhalofop-butyl Mode of motion Post-emergence herbicide with foliar uptake only and no soil action. A systemic herbicide that is commonly absorbed by plant tissue, is reasonably phloem-cell and accumulates in meristematic regions. Grass weeds cease progress quickly following treatment method, with yellow patches appearing inside of 2-three days to a single 7 days, major to necrosis and demise of the complete plant in 2 to 3 months.

Cyhalofop-butyl Uses For publish-emergence manage of grass weeds in rice. Applied at 75-one hundred g/ha in tropical rice and 180-310 g/ha in temperate rice. For selectivity in Poaceae species, see M. Ito et al., J. Weed Sci. & Tech., 1998, forty three(two), 122-128. Phytotoxicity Rice is completely tolerant to cyhalofop-butyl, owing to quick metabolic process to the inactive diacid.

Cyhalofop-butyl Compatibility Not suitable with most broad-leaved and sedge auxin and ALS herbicide products.

Bispyribac-sodium NOMENCLATURE
Widespread name bispyribac (BSI, E-ISO, (m) F-ISO, for the carboxylic acid) 
IUPAC name sodium 2,6-bis(4,6-dimethoxypyrimidin-2-yloxy)benzoate
Chemical Abstracts name sodium 2,6-bis[(four,6-dimethoxy-two-pyrimidinyl)oxy]benzoate 
CAS RN [125401-seventy five-4] acid [125401-92-5] sodium salt  

Bispyribac-sodium APPLICATIONS
Bispyribac-sodium Biochemistry Branched chain amino acid synthesis (ALS or AHAS) inhibitor.

Bispyribac-sodium Mode of action Selective, systemic post-emergence herbicide, absorbed by foliage and roots.

Bispyribac-sodium Uses Control of grasses, sedges and broad-leaved weeds, particularly Echinochloa spp., in immediate-seeded rice, at rates of fifteen-45 g/ha. Also utilized to stunt expansion of weeds in non-crop situations.
