Carboxin APPLICATIONS
Carboxin Biochemistry SDHI: inhibits mitochondrial function by disrupting complex II (succinate dehydrogenase) in the respiratory electron transport chain.
Carboxin Mode of action Systemic fungicide.
Carboxin Uses Seed treatment for control of smuts and bunts (particularly loose smut, Ustilago spp.), at 50-200 g/100 kg seed, on barley, wheat, and oats; seedling diseases (particularly Rhizoctonia spp.) of barley, wheat, oats, rice, cotton, peanuts, soya beans, vegetables, maize, sorghum, and other crops.
Carboxin Compatibility Not compatible with pesticides which are highly alkaline or acidic.
Difenoconazole NOMENCLATURE
Common name difénoconazole ((m) F-ISO); difenoconazole (BSI, E-ISO)Â
IUPACÂ name cis,trans-3-chloro-4-[4-methyl-2-(1H-1,2,4-triazol-1-ylmethyl)-1,3-dioxolan-2-yl]phenyl 4-chlorophenyl ether
Chemical Abstracts name 1-[2-[2-chloro-4-(4-chlorophenoxy)phenyl]-4-methyl-1,3-dioxolan-2-ylmethyl]-1H-1,2,4-triazoleÂ
CASÂ RNÂ [119446-68-3] unstated stereochemistryÂ
Difenoconazole APPLICATIONS
Difenoconazole Biochemistry Sterol demethylation inhibitor. Inhibits cell membrane ergosterol biosynthesis, stopping development of the fungus.
Difenoconazole Mode of action Systemic fungicide with preventive and curative action. Absorbed by the leaves, with acropetal and strong translaminar translocation.
Difenoconazole Uses Systemic fungicide with a novel broad-range activity protecting the yield and crop quality by foliar application or seed treatment. Provides long-lasting preventive and curative activity against Ascomycetes, Basidiomycetes and Deuteromycetes, including Alternaria, Ascochyta, Cercospora, Cercosporidium, Colletotrichum, Guignardia, Mycosphaerella, Phoma, Ramularia, Rhizoctonia, Septoria, Erysiphe and Venturia spp., Erysiphaceae, Uredinales and several seed-borne pathogens. Used against disease complexes in grapes, pome fruit, stone fruit, potatoes, sugar beet, oilseed rape, bananas, cereals, rice, soya beans, ornamentals and various vegetable crops, at 30-125 g/ha. Used as a seed treatment against a range of pathogens in wheat and barley, at 3-24 g/100 kg seed. Phytotoxicity In wheat, early foliar applications at growth stages 29-42 might cause, in certain circumstances, chlorotic spotting of leaves, but this has no effect on yield.

Roller bearing, one of the two members of the class of rolling, or so-called antifriction, bearings (the other member of the class is the Ball Bearing). Like a ball bearing, a roller bearing has two grooved tracks, or races, but the balls are replaced by rollers. The rollers may be cylinders or truncated cones. Only radial loads (i.e., loads perpendicular to the axis of rotation) can be carried when the rollers are cylindrical, but with conical rollers both radial and thrust, or axial, loads (i.e., ones parallel to the axis of rotation) can be carried. A needle bearing has cylindrical rollers that are relatively slender and completely fill the space between the races; in many cases the inner race is dispensed with. Because there is line contact between a roller and the races, while in a ball bearing there is point contact, in a given space a roller bearing can carry a greater radial load than a ball bearing.
Roller bearings are used in all main shaft and auxiliary drive shaft applications to support pure radial load, and allow for axial shaft elongation due to temperature changes with no additional load effect on the bearing. They are usually located at the ends of the turbine and compressor shafts and are often mounted in a housing, but separated from it by a layer of pressurized oil known as a squeeze film damper.
In many cases, instead of having a separate inner race for roller bearings, the [inner race" is an integral part of the shaft or stub shaft. This reduces complexity, weight, and build-up of concentricity tolerances. Overall, this is cost effective, but the cost of replacement or repair is likely to be higher than for separate inner races.
