The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 2,3,5-Trichloropyridin-4-ol( cas:1970-40-7 ) is researched.Application of 1970-40-7.Lynd, Julian Q.; Rieck, Charles E.; Barnes, Donald Kay; Murray, Don; Santelmann, Paul W. published the article 《Indicator plant aberrations at threshold soil herbicide levels》 about this compound( cas:1970-40-7 ) in Agronomy Journal. Keywords: HERBICIDE THRESHOLD LEVEL; CUCUMBERS HERBICIDE; FLUOMETURON CUCUMBERS; UREAS HERBICIDE; TRIAZINES HERBICIDE; PICLORAM THRESHOLD LEVEL. Let’s learn more about this compound (cas:1970-40-7).
The marginal chlorosis around the first true cucumber (Cucumis sativus) leaves appears very soon after their normal expansion growth is started and is a symptom for fluometoron (3-(m-trifluoromethylphenyl)-1,1-dimethylurea) poisoning. Leaves developing from the cotyledons are not affected. The characteristic leaf patterns with young cucumber plants were similar for fluometuron, fenuron, monuron, diuron, and norea, but the relative toxic activity among the herbicides differs considerably. The biodegradation of these compounds is relatively slow and is influenced by soil and climatic factors. The triazine herbicides are characterized by lethal interferences with plant photochem. mechanisms. The auxin type of growth manifestations is induced with extremely low concentrations of picloram (4-amino-3,5,6-trichloropicolinic acid), one of the most potent of herbicides. Cucumber plants are particularly sensitive to this herbicide. Pyriclor (2,3,5-trichloro-4-pyridinol) develops an interveinal chlorotic pattern in cucumber leaves. Leaves developing from cotyledons remain green and do not develop chlorosis. Plants may recover and regenerate healthy green tissue within chlorotic areas with very low levels of this herbicide. N-serve (2-chloro-6-(trichloromethyl)pyridine) influences plant growth with an auxin-type activity similar to picloram, but requires about a hundred-fold higher concentration than picloram for similar effects.
