In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called New directions in weed control research for tropical rice, published in 1968, which mentions a compound: 1970-40-7, Name is 2,3,5-Trichloropyridin-4-ol, Molecular C5H2Cl3NO, Quality Control of 2,3,5-Trichloropyridin-4-ol.
The use of phenoxyacetic acid herbicides with selective grass herbicides is efficient and less costly than earlier recommended methods. Granular formulations which are easy to apply to transplanted rice are available. Combinations recommended are EPTC-MCPA, trifluralin-MCPA, and nitrofen, propachlor, and pyriclor with either 2,4-D or MCPA. Techniques using paraquat, pyriclor, and a few other chems. have reduced tillage, and occasionally made zero tillage feasible. In the absence of perennial grasses and excessive accumulation of plant material, use of herbicides can make direct seeding of rice possible.
《New directions in weed control research for tropical rice》 provides a strategy for the preparation of materials with excellent comprehensive properties, which is conducive to broaden the application field of this compound(2,3,5-Trichloropyridin-4-ol)Quality Control of 2,3,5-Trichloropyridin-4-ol.
