Selective algaecides for control of cyanochloronta
We have now discovered that certain 9,10-anthraquinone derivatives we developed possess potent activity against O. perornata while possessing a sufficiently high level of solubility in water to make their activity against O. perornata viable. These compounds possess a high level of activity against O. perornata yet are relatively non-toxic to green algae and fishes. The compounds also possess a relatively short half-life. The compounds represent a new means to providing compounds possessing a high degree of selective activity against blue-green algae while being physiologically tolerated by catfish and green algae. The compounds provide a means for controlling blue-green algae in managed bodies of water that are destined for public use or consumption.

Combinations of individual colorant compounds that provide effective toning (or bluing) to combat yellowing within polyester articles (such as bottles, containers, and the like) are provided. Such a novel toner combination permits effective neutralization of yellowness while also providing highly desirable low haze and increased brightness due to a sharp absorption peak within the needed range of wavelengths (e.g., from about 565 to 590 nm) and a narrow half-height band width. Furthermore, such a combination of compounds is preferably liquid in nature and may thus be incorporated within an added ultraviolet absorber solution or shelf-stable dispersion to facilitate addition within target polyesters at various stages of production. The particular UV absorbers desired as additives within target polyesters also tend to exhibit certain yellowing effects that require attention as well.
