New herbicides for control of dicots in cereals, not undersown. Aamisepp, Ants (Dep. Plant Husb., Swed. Univ. Agric. Sci., Uppsala S-750 07, Swed.). Weeds Weed Control, 26th(1), 26-38 (English) 1985. CODEN: SWDCAZ. ISSN: 0375-3034. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Reports of field trials with the herbicides Glean [64902-72-3], chlorsulfuron [64902-72-3], Oxitril [1689-84-5], mecoprop [7085-19-0], DPX T 6376 [74223-64-6], Dowco 433 [81406-37-3], KVK 304 [97984-93-5], and MCPA [94-74-6] in spring and winter cereals are presented. Dowco 433 gave good control of some weeds, and using Dowco 433 with MCPA ester or with loxnynil estrer/Lontril gave more complete control. For good weed control with acceptable phytotoxicity in oats Dowco 433 with MCPA ester is recommended. For weed control in winter cereals KVK304 gave good results.

Radiation chemical degradation of the herbicide bromoxynil (3,5-dibromo-1-hydroxy-benzonitrile)

Radiation chemical degradation of the herbicide bromoxynil (3,5-dibromo-1-hydroxy-benzonitrile). Luther, Dieter; Abendroth, Hans Christoph; Koennecke, Hans Guenther (Zentralinst. Isot. Strahlenforsch., Dtsch. Akad. Wiss., Leipzig DDR-7050, Ger. Dem. Rep.). Z. Chem., 25(6), 221 (German) 1985. CODEN: ZECEAL. ISSN: 0044-2402. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) The degrdn. of 82Br-labeled bromoxynil [1689-84-5] in aq. soln. was monitored in response to various doses of gamma radiation (60Co source, energy dose 1-10 kGy). Degrdn. of bromoxynil followed a 1st order reaction. Bromoxynil was transferred into nonextractable products at relatively small energy doses.
