Berries within the enclosure were harvested with a hand scoop, but no attempt was made to pick every berry. In the laboratory, berries were individually rated as "salable" or "rotted," grouped, and weighed to obtain percent- ages of rotted fruit and total yields. Cup counts of salable berries were used to determine differences in berry size among treatments. Salable berries were then placed in storage

Berries within the enclosure were harvested with a hand scoop, but no attempt was made to pick every berry. In the laboratory, berries were individually rated as "salable" or "rotted," grouped, and weighed to obtain percent- ages of rotted fruit and total yields. Cup counts of salable berries were used to determine differences in berry size among treatments. Salable berries were then placed in storage for five weeks, at which time a second assessment of rot was made based on original total yields. Pre-bloom and Fruitworm Treatments. The appropriate plots received either one pre-bloom treatment on June 13 or two treatments for cranberry fruit- worm on July 14 and 24. On all dates parathion 8E at 1 pint per acre was applied in water at 400 gallons per acre, using a 1 gallon Hudson back-pack sprayer. Precip- itation did not occur within 24 hours after each application. On October 4 a circular metal hoop enclosing an area of 1 square foot was dropped onto an unharvested part of each plot, and the berries inside the hoop were carefully hand-picked. No regard was given to berry size or condition. Berries were inspected and percentages of infestation determined. Analysis of Data. All data pertain- ing to fruit rot and fruitworm damage, cup counts, and yield of salable berries were analyzed statistically, using analysis of variance and one other test. Results and Discussion. Results of the experiments are presented in Table 1. Regarding fruit rot, low levels of disease in all plots did not allow the effectiveness of maneb treatments to be demonstrated. At harvest the percentage of rotted fruit in the "fruit rot plus pre-bloom insects" plots seemingly exceeded that in the "fruit rot plus fruitworm" plots. This difference did not occur after fruit had been stored f
