| Abstract |
The primary objective of the project was to determine under natural, open-field conditions, the efficacy of two candidate algaecides, Compound No. 23 (2,5-Dichloro-3,4-dinitrothiophene) and No. 73 (p-Chlorophenyl-2-thienyl iodonium chloride) from Phase II of the multiple phase developmental program. Specific efforts were also directed toward further delineation of the toxicological and environmental persistence properties of the candidate compounds, as well as further development of a possible biological-chemical control system. Data from the field tests conducted under a wide variety of conditions in four geographically diverse regions of the United States revealed a distinctive pattern of selective blue-green algal control for both experimental compounds. Compound No. 23 was eliminated from the test series due to unacceptable fish toxicity. Continued laboratory screening tests of some 70 additional compounds produced two additional candidate compounds. |
