Effect of biologically active substances on storage rot pathogens of carrots

Effect of biologically active substances on storage rot pathogens of carrots. Koltunov, V. A.; Ustinov, I. D.; Ustinova, A. F.; Yatsenko, E. A. (USSR). Zashch. Rast. (Moscow), (7), 18-19 (Russian) 1984. CODEN: ZSRSBX. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Section cross-reference(s): 17 Dipping seed carrots in 0.7% TMTD [137-26-8] or 0.001% K metabisulfite [16731-55-8] for 45 s controlled white rot caused by Sclerotinia sclerotiorum and increased the output of roots suitable for planting from 94.50 to 98.76 and 99.66%, resp., and decreased losses of vitamin C [50-81-7]. Dipping in Na metabisulfite [7681-57-4], ascorbic acid, a-NAA [86-87-3], or phenylacetic acid [103-82-2] also preserved the carrots. Preservation of seed roots with K metabisulfite or ascorbic acid decreased the losses in the seed plantation from 22.5 and 23.4 to 15.4 and 12.9%, resp., and increased seed yield by 3.2-3.6 quintals/ha. In lab. expts. nicotinic acid [59-67-6] and infusions of horseradish, garlic, and onions also retarded the growth of S. sclerotiorum.

Deposition of nickel-boron alloy layers from modified electrolytes

Deposition of nickel-boron alloy layers from modified electrolytes. Stallmann, K.; Speckhardt, H. (Tech. Hochsch., Darmstadt, Fed. Rep. Ger.). Metall (Berlin), 39(3), 238-46 (German) 1985. CODEN: MTLLAF. ISSN: 0026-0746. DOCUMENT TYPE: Journal CA Section: 56 (Nonferrous Metals and Alloys) The effects of various additives, esp. stabilizers, to conventional electroless Ni-B [11143-14-9] coating baths contg. NiCl2, NaBH4, NaOH, C2H4(NH2)2, and toxic Tl2SO4 as stabilizer on the required lamellar or structure-free coating to prevent formation of dendritic layer structure were investigated. Various salts and stabilizers were effective in a certain concn. range, and dendritic layer structure was achieved mostly at higher concns. Pb(AcO)2 at 0.075-0.1, Cd(AcO)2 at 0.1, HgCl2 at 1, Mo chloride at 0.01, coumarin at 0.01, Na benzosulfonate 1, vanadyl acetylacetonate 1 g/L generated a glossy, fine-dendritic, or lamellar structure. Efficient stabilizers were Dodigen 5462 [96510-64-4] at 5-10, fluoro surfactants FT219 [96538-29-3] at 10, FT229 [96538-30-6] 1-10, Dodigen 481 [55068-98-9] at 0.2-1, and Hoesch E1641 [96510-65-5] at 1 mL/L. Use of stabilizing system of K2S2O5 [16731-55-8] with KNa tartrate [304-59-6] resulted in stable coatings in large bath vol. for 31 h without a dendritic layer structure. Hardness and structure of the layer were not changed by heat treatment.
