Thus, 2-[2-chloro-4-(4-chlorophenoxy)phenyl]-2-(1,2,4-triazol-1-ylmethyl)-4-me thyl-1,3-dioxolane was heated with S in N-methylpyrrolidine at 200° for 22 h to give 41% 2-[2-chloro-4-(4-chlorophenoxy)phenyl]-2-(5-mercapto-1,2,4-triazol-1-yl methyl)-4-methyl-1,3-dioxolane. .

Suppression of Alternaria leaf spot in Pima cotton by systemic fungicides

Suppression of Alternaria leaf spot in Pima cotton by systemic fungicides. Shtienberg, D.; Dreishpoun, J.Several substances are used for example 12427-38-2 and 119446-68-3 which are their cas registry numbers. (Fac. Agric., Hebrew Univ. Jerusalem, Rehovot 76100, Israel). Crop Prot., 10(5), 381-5 (English) 1991. CODEN: CRPTD6. ISSN: 0261-2194. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) The effects of difenoconazole, tebuconazole (systemic fungicides) and maneb (a protectant fungicide) on Alternaria leaf spot (Alternaria macrospora) and on yields of Pima cotton were detd. in five field trials conducted in 1989 and 1990. Disease-induced defoliation was calcd. as the sum of weighted ests. of the disease severity of attached leaves and the proportion of shed leaves. In all trials, difenoconazole at a rate of 0.125 kg ha-1 and tebuconazole at 0.187 kg ha-1 suppressed disease to a significant extent relative to untreated plots, and differences in yield (15.6-39.0% increase) between treated and untreated plots were significant. Although maneb (at 2.0 kg ha-1) also suppressed disease significantly, in four of the trials the yield differences (6.3-26.0% increase) between treated and untreated plots were insignificant. In general, defoliation and yields did not differ significantly among the different fungicide treatments. The systemic fungicides exhibited some curative properties because of their effects in suppressing previous infections. .
