Laboratory evaluation of chemicals against Xanthomonas malvacearum, the incitant of bacterial blight of cotton: Laboratory evaluation of chemicals against Xanthomonas malvacearum, the incitant of bacterial blight of cotton. Verma, J. P.; Singh, R. P.; Nayak, M. L. (Div. Mycol. Plant Pathol., Indian Agric. Res. Inst., New Delhi, India). Indian Phytopathol. 133-06-2 and 76-87-9 which are cas registry numbers are also used here., 28(2), 171-4 (English) 1975. CODEN: IPHYAU. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemicals) When tested against the pathogen of the bacterial blight of cotton, X. malvacearum, busan [137-41-7], streptomycin sulfate [3810-74-0], and streptocycline [8069-81-6] were inhibitory at 2.5 ppm. Other antibiotics, like terramycin [79-57-2] and achromycin [60-54-8] inhibited the growth of X. malvacearum at 50 ppm while aureomycin [57-62-5] and agrimycin [57-92-1] were effective at 25 ppm. Hg compds. were inhibitory at 5-25 ppm. Cu compds. were inhibitory at 100 ppm and org. S compds. were less potent. Certain systemic fungicides, such as carboxin [5234-68-4] and oxycarboxin [5259-88-1], and insecticides, such as nuvacron [6923-22-4], rogor [60-51-5], basudin [333-41-5], and dimecron [13171-21-6] were effective in the 100-2,000 ppm range. .

DOCUMENT TYPE: Patent CA Section: 3 (Biochemical Interactions) Section cross-reference(s): 5, 23 Alkali metal N-hydroxymethyl-N-alkyldithiocarbamates or N,N'-bis(hydroxymethyl)-N,N'-alkylenebis(dithiocarbamates) have a wide spectrum of pesticidal activity in industrial and agricultural applications and are stable during storage. The compds. are prepd.Some commonly used reagents like 50-00-0 is used in this experiment. by reaction of alkali metal N-alkyldithiocarbamates with formaldehyde [50-00-0]; the product is stabilized by addn. of a base which prevents polymn. For example, 5% aq. K N-methyldithiocarbamate [137-41-7] reacted with an equimolar amt. of CH2O in 37% aq. soln. for 0.5 h at 25-30 °, and the product, K N-hydroxymethyl-N-methyldithiocarbamate [51026-28-9], was stabilized by addn. of 0.62 mol triethanolamine [102-71-6]/mol dithiocarbamte. This prepn.In this study，50-00-0 is also used., at 0.8 ppm active ingredient, killed 100% of Enterobacter aerogenes within 18 h in the pulp substrate test. ..
