144 MAINE AGRICULTURAL EXPERIMENT STATION. I902. 



side of the plot. Plot 4. Some slugs, rather less than on plot 1 and small. 

 Plot 5. About the same as plot 4. Very few slugs. Plot 6. Had no 

 slugs ; all smaller than on plot 5 ; vines somewhat eaten. Plot 7. Very 

 few slugs, less than on 1 or 4. Plots 8-9. Few small slugs, about same 

 as plot 2. Plot 10. Practically no slugs, cleaner than any of the pre- 

 ceding plots. Plots 11-12. About the same as plot 5, rather less slugs, 

 if anything. 



August 2 all sprayed. 



August 5. Plot 1. Very few slugs, a few old bugs, tops not eaten. 

 Plot 2. No small slugs, a few large ones, tops eaten more than on 1. 

 Plot 3. About the same as plot 2, perhaps not eaten so much nor quite 

 so many slugs. Plot 4. Practically no bugs or slugs, tops very little 

 eaten. Plot 5. Practically as plot 4 as regards bugs, the tops appeared 

 larger than the preceding plots. Plot 6. About the same as 3, not as free 

 from bugs and slugs as 4 and 5, eaten rather more than 4 or 5, tops fully 

 as large as on plot 5. Plot 7. About as plot 4 but not so much eaten. 

 Plot 8. Slugs and bugs as on plot 2, perhaps tops not quite so much eaten. 

 Plot 9. Rather better than 6, less bugs and less eaten than on plot 6. 

 Plot 10. Cleanest from bugs and less signs of their work than on any of 

 the plots 1 to 9. Plot 11. Very clean, but not quite so free from bugs 

 as 10 and more traces of their work than on plot 10. Plot 12. Not quite 

 so free from bugs as plot 11 and more eaten. Plots 1 to 12, for all prac- 

 tical purposes, are very free from bugs, a few leaves on occasional plants 

 had been eaten to a small extent. No plants on the whole piece damaged 

 enough to have any probable effect on yield. 



August 27 some blight on all of the plots, leaves yellowed on some 

 plots. Occasional spots on some green leaves. No perceptible difference 

 between the plots of each different kind of insecticide that was used. The 

 general appearance of the crop is too light color to the tops. It is more 

 marked on some rows and especially on the plots near the north side of 

 the field. Some rows are much more affected than others. There is no 

 bloom to be seen on the entire field at a distance. An occasional plant 

 is in the last stage of flowering. The Bug Death was used on plots 2, 5, 

 8, 11, but no insecticides on the other plots. 



September 2. blight on unsprayed fields has made much progress in the 

 past week. Vines with stalks and leaves green a week ago have 

 only the stems left. On Air. Watson's fields, which had not been sprayed 

 for four weeks, the disease had progressed considerably. The experi- 

 mental plots are about the same as a week ago, still green with some 

 blight. No noticeable difference between different plots. 



September 11. Blight has made a good deal of progress. A few plants 

 died on all the plots ; many plants still as green as ever and most of the 

 plants are quite green. No perceptible difference between the different 

 plots. The plots were harvested October 8. 9 and 10. The tops were all 

 dead, having been killed by frost about the middle of September.
