DOCUMENT TYPE: Patent CA Section: 5 (Agrochemical Bioregulators) Compns. contg. dichloroquinoline derivs. I (R' = H, halogen, CN, etc.; X = 5-, 6-, 7-Cl; Y = O, S, hydroxyimino, H2, Cl2, etc., or where Y and R' together with their C atom form a nitrile group) and propionic acid 3,4-dichloroanilide (II) [709-98-8] are herbicides, esp. for rice and cereals. Thus, spraying 3,7-dichloro-8-carboxyquinoline [84087-01-4] 0.125 and II 3.0 kg active ingredient/ha synergistically controlled Echinochloa in rice. The herbicides were not phytotoxic to rice.

Residual dynamics of quinclorac and its metabolite in rice field environment and rice

Residual dynamics of quinclorac and its metabolite in rice field environment and rice. Lu, Zhongbin; Liu, Yiling; Xu, Wei (College Business, Jilin Agricultural University, Changchun 130118, Peop. Rep. China). Huanjing Kexue Xuebao, 16(4), 503-506 (Chinese) 1996 Kexue. CODEN: HKXUDL. ISSN: 0253-2468. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) The residual dynamics of the quinclorac in rice field in northeast China was studied. The residues of quinclorac and its metabolite (BH514-1) in soil were detd. by reversed phase HPLC method using a Shim-Pack CLC-CN column and methanol-water (contg.In this article, certain chemicals are used. One of their cas registry numbers is 84087-01-4 0.5% HAc) ( (V/V)) as mobile phase. Results of the two year's study showed that the half-life of quinclorac in soil, water and rice plant were 8-11, 2-3 and 0.6-0.7 days, resp. The final residues in soil, brown rice and rice straw were all below their detectable limits of 0.003, 0.005 and 0.012 mg/kg resp. The residue of BH514-1 in soil was not detected. The results provided a basis for safety application of quinclorac. .
