Reference of 2,3,5-Trichloropyridin-4-ol. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 2,3,5-Trichloropyridin-4-ol, is researched, Molecular C5H2Cl3NO, CAS is 1970-40-7, about Inhibition of photosynthesis by pyriclor. Author is Meikle, Richard W..

The effect of pyriclor on some photochem. reactions that bring about the formation of assimilatory power, the generation of ATP and NADPH, at the expense of radiant energy was determined by using isolated Spinacia oleracea var Viroflay (spinach) chloroplasts. The assimilation of CO2 and cyclic photophosphorylation catalyzed by FMN both showed inhibition at a rather high level of pyrichlor; however, O evolution and noncyclic photophosphorylation were strongly inhibited. Evidence is presented to support the conclusion that the locus of attack is the O-evolving system and (or) Pigment System 2 of the photosynthetic apparatus

COA of Formula: C5H2Cl3NO. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: 2,3,5-Trichloropyridin-4-ol, is researched, Molecular C5H2Cl3NO, CAS is 1970-40-7, about Performance of several herbicides for weed control in peanuts. Author is Buchanan, Gale A.; Dickens, Ray; Burns, Earl R.; McCormick, Robert M..

Experiments were conducted on Dotahn fine sandy loam in Ala. Preplant incorporated herbicides were blank planted, and preplant herbicides applied, then Early Runner peanuts were planted. Stands were not reduced and yield was not usually affected. 4-(Methylsulfonyl)-2,6-dinitro-N,N-dipropyl-aniline (nitralin), 2-chloro-2′,6′-diethyl-N-(methoxymethyl)-acetanilide (CP 50144), methyl-2,3,5,6-tetrachloro-N-methyltere-phthalamate (OCS 21693), and UC 22463 (80% 3,4-dichlorobenzyl-N-methyl carbamate + 20% 2,3-dichlorobenzyl-N-methyl carbamate) consistently controlled crabgrass (Digitaria sanguinalis), goosegrass (Eleusine indica), and crowfootgrass (Dactyloctenium aegyptium). These herbicides gave poor control of Florida beggarweed (Desmodium tortuosum), sicklepod (Cassia obtusifolia), and tall morning glory (Ipomoea purpurea). Pyriclor (2,3,5-trichloro-4-pyridinol) gave excellent full season grass and broadleaf weed control at rates as low as 0.4 lb/acre; 2.0 lb/acre or more usually caused substantial injury to peanuts. Delaying application of pyriclor resulted in greater chlorosis in peanuts. Pyriclor applied in combination with nitralin, benefin (N-butyl-N-ethyl-α,α,α-trifluoro-2,6-dinitro-p-toluidine), or vernolate (S-propyl dipropylthiocarbamate) gave better weed control than either of these herbicides alone, but was no better than pyriclor alone. The major effect of incorporation of pyriclor appeared to be dilution OCS 21799 (2-(4-chloro-o-tolyl)oxy-N-methoxyacetamide) applied at 0.5-4.0 lb/acre gave good early season control of grasses and broadleaf weeds, but did not give long season control.

A major problem in mech. harvesting of cotton is to efficiently remove or desiccate the leaves and inhibit further growth. The major areas of study are: defoliation, desiccation, regrowth inhibition, wilt agents, and effects of harvest-aid chem. on boll weevils. Various chem. agents were tested against amitrole as control. Pyrichlor was most active as regrowth inhibitor when applied at 0.5 to 0.7 5 lb/acre, about half that of amitrole. Paraquat increased the defoliant activity of Def and Folex. GC 7887 is a promising defoliant. Defoliants had little effect on weevil numbers, whereas desiccants decreased the number of weevils, probably because they reduced the food supply. Chem. residues were not detected after 5 months in treated soil or seed samples.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Differential response of ditchbank grasses to herbicides, published in 1973, which mentions a compound: 1970-40-7, mainly applied to grass control herbicide; dalapon grass control; amitrole grass control; pyriclor grass control, Electric Literature of C5H2Cl3NO.

The undesirable plants reed canarygrass, quackgrass, and smooth brome were consistently more susceptible to 3-amino-s-triazole-ammonium thiocyanate (amitrole-NH4SCN) [51365-94-7] than were 3 desirable short grasses Kentucky bluegrass, creeping red fescue, and redtop. Reed canarygrass and redtop were more susceptible to dalapon [75-99-0] than was creeping red fescue. Amitrole-NH4SCN-dalapon mixture in various combinations was more toxic to reed canarygrass, smooth brome, and redtop than to creeping red fescue. Pyriclor (I) [1970-40-7] was quite toxic to all the grasses, with Kentucky bluegrass showing the most tolerance. Trichloroacetic acid-amitrole-NH4SCN mixture was similar in activity to the mixture with dalapon, but had less overall toxicity.

Weed control performance of several herbicides, their effects on tobacco (Nicotiana tabacum), and 2 methods of soil incorporation were studied in North Carolina in 1967 and 1968. Herbicides which gave acceptable weed control without injuring tobacco or lowering its quality were 4-(methylsulfonyl)-2,6-dinitro-N,N-dipropylaniline (nitralin), 1,1,4-trimethyl-6-isopropyl-5-indanyl ethyl ketone (D 497), Me 3-amino-2,5-dichlorobenzoate (amiben), N-butyl-N-ethyl-α,α,α-trifluoro-2,6-dinitro-p-toluidine (benefin), S-propyl butylethylthiocarbamate (pebulate), S-propyl dipropylthiocarbamate (vernolate), N,N-dimethyl-2,2-diphenylacetamide (diphenamid), dimethyl tetrachloroterephthalate (DCPA), 2,3,5-trichloro-4-pyridinol (pyriclor), and 2-(α-naphthoxy)-N, N-diethylpropionamide (R 7465). Soil incorporation of benefin, pebulate, and benefin + vernolate with a power-driven rotary cultivator gave superior weed control compared to incorporation by disking 4 times. Significant early-season stunting of tobacco plants was observed both years in plots where benefin (1.12 or 2.25 lb/acre), benefin + vernolate (0.75 + 1.5 lb/acre), or benefin + pebulate (1.12 + 4.0 lb/acre) was incorporated by disking. No stunting was observed where incorporation was with the rotary cultivator except for benefin at 2.25 lb/acre. Neither yield nor quality of the crop was reduced.

This literature about this compound(1970-40-7)SDS of cas: 1970-40-7has given us a lot of inspiration, and I hope that the research on this compound(2,3,5-Trichloropyridin-4-ol) can be further advanced. Maybe we can get more compounds in a similar way.

Recommanded Product: 2,3,5-Trichloropyridin-4-ol. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 2,3,5-Trichloropyridin-4-ol, is researched, Molecular C5H2Cl3NO, CAS is 1970-40-7, about Redvine growth and control. Author is Baker, R. S..

Redvine (Brunnichia cirrhosa) was established as a spaced planting in a silt loam soil. Fourteen months after the seedlings had been transplanted in the field, the roots had reached a depth of 1.5 m. The cumulative length of all roots averaged 28 m/plant. The average dry weight, of roots was 62 g and of shoots 247 g/plant. Herbicide application on redvine 2 or 3 yr after transplanting gave excellent control with dicamba [1918-00-9] and picloram [1918-02-1]. Dicamba required a rate of 4.5 kg/ha for satisfactory redvine control, which resulted in hazardous soil residues for cotton and soybeans. Picloram at 1.1 kg/ha resulted in soil residue which severely injured cotton and soybeans. Picloram at the same rate, but combined in a tank mix with 2,4-D [94-75-7] at 2.2 kg/ha gave nearly as good redvine control, but resulted in relatively little crop injury in the bioassay test 1 yr after treatment.

Computed Properties of C5H2Cl3NO. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: 2,3,5-Trichloropyridin-4-ol, is researched, Molecular C5H2Cl3NO, CAS is 1970-40-7, about Selectivity of 2,3,5-trichloro-4-pyridinol as a herbicide for direct-seeded, flooded rice. Author is Moomaw, J. C.; Kim, D. S..

Field and greenhouse experiments showed that 2,3,5-trichloro-4-pyridinol (pyriclor) (I) at 50-500 g./ha. controlled the grass weed, Echinochloa crus-galli, in direct-seeded rice. I prevented germination and restricted growth of the weed under both static and percolating water conditions, but permitted rice to germinate and grow normally. I was most effective when applied early, and treated plots gave higher yields than those handweeded or sprayed with propanil. Grass-weed control was as effective as that of molinate (S-ethylhexahydro-[1H]-azepine-1-carbothioate) (II) or nitrofen (2,4-dichlorophenyl-4-nitrophenyl ether) applied at much higher rates. Dichlobenil (2,6-dichlorobenzonitrile) inhibited rice germination and was toxic to young seedlings, and is thus unsuitable for direct-seeded rice. II had a wider range of latitude in time of application than the other herbicides. Greenhouse experiments indicated that I moves down in percolating water but is adsorbed more readily in fine than in coarse-textured soils.
