Kepone® Residues In Chesapeake Bay Biota, M. E. Bender, R. J. Huggett, W. J. Hargis Jr.
VIMS Books and Book Chapters
Oysters from the James displayed variations in Kepone residue levels related to water temperature and their spawning cycle. Oyster depuralion rates were related to temperature. In summer the "biological half. life" of Kepone in oysters was about one week, while during the winter about 40 days were required for residue levels to decline by 50 per cent. Residues in blue crabs varied as a function of sex, males having considerably higher residues than females. Fin fish levels from the James varied greatly, with residue levels being dependent on species and length of residence for migratory fishes .. Average Kepone residues …

COMMENTS 1. No insect problems experienced and broadleaf weeds effectively controlled by spraying. Septoria· leaf spot incidence insufficient to affect yields. 2. Little effect of time of planting on either total dry matter or grain yield. Crop received about 70% of the average May-October rainfall with a very dry September-October. Perhaps the distribution of rainfall allowed a similar pattern of water use, and total water use by each planting time. 3. There is probably a significant effect of Nitrogen regime on grain yield. Osmocote (N3) consistently yielded more than either single (N1) or repeated (N2) dressings of Agran 34:0. The …

(1) Yield assessments have continued similar to those used in 1977 and 1978. Essentially, plants with symptoms typical of BYDV are marked in the early spring as well as a similar number without symptoms. Yield differences were obtained both for Clipper Barley and an oats variety. (2) Two pilot experiments using viruliferous aphids were carried out at Mount Barker (79MT20) and at South Perth · (79PE13). Both Rhopalosiphum padi and R. maidis were used. Infection at Mt Barker failed, and therefore no data is presented. The Perth experiment was planted on August 31, 1979. The original plan was to have …
