Effect of herbicide and soil tillage on yield of direct seeded bunded rice

Effect of herbicide and soil tillage on yield of direct seeded bunded rice. Pane, Hamdan; Noor, Sutisna (Bogor, Indonesia). Penelitian Pertanian, 3(1), 13-16 (Indonesian) 1983. CODEN: PEPREJ. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Direct seeded bunded rice or gogorancah rice often suffers from water stress and serious weed infestation, esp. during the 1st 6 wk of the growing season. The effects of 3 methods of land prepn. before seeding and of weeding and various herbicides on the nos. and types of weeds were examd. Conventional tillage gave heavy infestations of grasses and sedges. Min. tillage by slicing the soil at 2-3 cm depth and plowing once followed by glyphosate [1071-83-6] (1.2 kg/ha) resulted in heavy infestation by grasses. There were no significant differences in grain yields among all the soil tillage methods tested. The application of thiobencarb [28249-77-6]/propanil [709-98-8] (4.8 kg/ha) at 14 days after seeding best suppressed the weeds and gave the highest yield. This yield was 34% higher than that in plots weeded twice. Yield losses due to weed competition ranged from 31 to 69%.

Herbicidal compositions containing dichloropropionanilide and carbamates

Herbicidal compositions containing dichloropropionanilide and carbamates. (Toyo Soda Mfg. Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 59164707 A2 17 Sep 1984 Showa, 24 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: A01N047-22. ICI: A01N047-22, A01N037-22. APPLICATION: JP 83-39056 11 Mar 1983. DOCUMENT TYPE: Patent CA Section: 5 (Agrochemical Bioregulators) Compns. contg. 3',4'-dichloropropionanilide (I) [709-98-8] and one or more of carbamates are herbicides. Thus, a compn. contg. I and O-2-naphthyl N-(6-methoxy-2-pyridyl)-N-methylthiocarbamate [88569-82-8] (5 + 10 g/are) controlled Echinochloa crus-galli, Cyperus diformia, Monochoria vaginalis, and Rotala indica in rice. There are some commonly used reagents like 709-98-8 in this article. .
