Ten fungicides were evaluated in 3 experiments over 3 years for control of Sigatoka leaf spot, which is the major foliar disease of bananas in North Queensland. Benomyl(150 g a.i./ha), bitertanol(126 g a.i./ha), carbendazim (1 50 g a.i./ha), DPX H6573 (100 g a.i./ha), mancozeb (1760 g a.i./ha), nuarimol (60 g a.i./ha), propiconazole (50 g a.i./ha), RH3866 (250 g a d h a ) and triademenol (100 g a.i./ha), all applied with mineral oil (4 L/ha), and chlorothalonil (1300 g and 900 g a.i./ha) and propiconazole (100 g a.i./ ha), applied alone, all reduced the severity of leaf spot (P < 0.05). Bunch weights were increased by all fungicides compared with untreated plants during 1984 (P < 0.05). Effective disease control reduced the problem of premature fruit ripening from 100% of bunches in untreated plots to 0% in propiconazole (50 g a.i./ ha + oil and 100 g a.i./ha alone) treatments. Propiconazole was the most effective fungicide, applied either continuously (50 g a.i./ha + oil, or 100 g a.i./ha alone) or alternated (50 g a.i./ha + oil) with mancozeb + oil in a spray program. Propiconazole, bitertanol and nuarimol significantly reduced the size of Sigatoka lesions (P=0.05). An experimental fungicide DPXH6573 gave good disease control in 1985 and warrants further investigation.

Abstract NIROSTA 4002 is an apparatus structural steel with 13% Cr. It is used for crack-resistant installations in the mineral oil industry because it has a high level of resistance against hydrogen and hydrogen sulfide. This chromium steel requires a smoothened surface free from residues in order to achieve optimal resistance to corrosion. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on high temperature performance as well as forming, heat treating, machining, and joining. Filing Code: SS-856. Producer or source: ThyssenKrupp Nirosta GmbH.

IR spectroscopy investigated structural and group composition of base mineral oils isolated from the vacuum distillate by selective purification of N-methylpyrrolidone and the low temperature dewaxing in the presence of a solvent. The role of the latter was carried out by the systems acetone - toluene, acetone - methyl tertiary butyl ether, methyl ethyl ketone - toluene, acetone - toluene - modifying additive. It was shown that the chemical composition of the group of base oils and slack waxes is defined as the nature of the solvent to the dewaxing, and oils sequence of purification steps.
