Mildews

Karathane A trade name for 2,4-dinitro-6-( 1 -methylheptyl)phenyl crotonate, CJ8H24N2O6, a compound which has both acaricidal and fungicidal activity. It is a red-brown oil of high boiling point, insoluble in water but soluble in most organic solvents. Karathane is used for the control of powdery mildew, and is nontoxic to mammals. 

FWWMR Finish. The abbreviation for fire, water, weather, and mildew resistance, FWWMR, has been used to describe treatment with a chlorinated organic metal oxide. Plasticizers, coloring pigments, fiUers, stabilizers, or fungicides usuaUy are added. However, hand, drape, flexibUity, and color of the fabric are more affected by this type of finish than by other flame retardants. Add-ons of up to 60% are required in many cases to obtain...

The almost exclusive use of tria2oles foi ceieal powdery mildew control up to the mid-1980s has resulted in a shift in E.Tysiphe populations toward reduced sensitivity or resistance to this class of fungicides. However, use has continued because field performance of most tria2oles has remained adequate (43). Decreased a2ole sensitivity in the population to a2oles has also been noted. 

Whereas semigloss paints can use only one extender, dat paints, especially interior, can use combinations of three or more. Gloss paints typically do not use extenders, which decrease gloss. As a result, gloss paints lack the hardening effect of extenders and must rely on harder binders for adequate durabihty. Other types of extenders used in paints can have functional properties such as corrosion resistance, mildew resistance, and film-hardening effects. Thek functional properties result from thek reactive nature in the paint film. Zinc oxide is an example of a functional extender that contributes to these properties in a paint film. 

Calcium Hypochlorite. High assay calcium hypochlorite [7778-54-3] was first commercialized in the United States in 1928 by Mathieson Alkali Works, Inc. (now Olin Corp.) under the trade name HTH. It is now produced by two additional manufacturers in North America (Table 5). Historically, it usually contained about 1% water and 70—74% av CI2, so-called anhydrous product, but in 1970, a hydrated product was introduced (234). It is similar in composition to anhydrous Ca(OCl)2 except for its higher water content of about 6—12% and a slightly lower available chlorine content. This product has improved resistance to accidental initiation of self-sustained decomposition by a Ht match, a Ht cigarette, or a small amount of organic contamination. U.S. production in the 1990s consists primarily of partially hydrated Ca(OCl)2, which is sold as a 65% av CI2 product mainly for swimming pool use. Calcium hypochlorite is also sold as a 50% av CI2 product as a sanitizer used by dairy and food industries and in the home, and as a 32% product for mildew control. 

Boron, as barium metaborate, is marketed as a mildew preventative for paints (273). Borax is used as a wood preservative, and an organic boron, 2,2 -(l-methyltrimethylenedioxy)-bis(4,4,6-trimethyl)-l,3,2-dioxaborinane (Biobor JF) [14697-50-80] is a biocide for jet fuel (274). Whereas tin metal is used to coat steel cans used as food containers, organic tin in the form of tributyl tin compounds have proven to be powerfiil antimicrobials, and have found use in antifouHng coatings for ship bottoms, paints, and wood preservatives (275). 

Few naturally occurring fused-ring thiiranes are known. Recently, however, humulene-1,2- and -4,5-episulfides (84) and (85), and caryophyllene-4,5-episulfide (86) were isolated from hops which had been heavily dressed with sulfur during the growing period, to control mildew (80JCS(P1)311). 

Fungi any of a group of parasitic lower plants that lack chlorophyll, including molds and mildews. 

Combination metallic and nonmetallic cloths consist of metallic wires and weak cloth or asbestos threads. There are some difficulties in weaving when attempting to maintain uniformity between wires and the cloth, and considerable dissatisfaction has been experienced with such construction. While cotton weaves well with the asbestos, the cotton fibers destroy the fabric s resistance to heat and corrosion. Its use is, therefore, quite limited, despite its resistance to high temperatures, acids and mildew.
