EXPERIMENTS WITH FUNGICIDES ON POTATOES. 53 



shower was very light but it did not clear up again during the 

 day. Blight was reported as having been found in several fields 

 in Houlton and vicinity. No signs of blight in this field unless it 

 be on a few leaves on north un sprayed end rows. 



Aug. II. Rows 113 to 224 sprayed. 



Aug. 14. Plants still in bloom so that the blossoms are con- 

 spicuous at a distance. Came up unexpectedly because of tele- 

 gram saying that blight had appeared in the field. The blight 

 was apparent in a few places on the low parts of the whole field. 

 The plants were all carefully examined and the following notes 

 taken : Rows 1 to 16. For two rods at east where ground is 

 low and soil heavy, it has been very wet and plants are small and 

 poor. There is some blight here on lowest leaves. In a hollow 

 near east end where the plants are rank, soft and "leggy," there 

 is a little bligfht on a few of the lowest leaves. Otherwise prac- 

 tically no blight on plot. Rows 17 to 32. Very well sprayed. 

 A few leaves are brown, or have brown tips. If there was no 

 blight elsewhere should not suspect these. Rows 35 to 48. Well 

 sprayed. There are a few blackened leaves, apparently bruised 

 at last spraying. Very little, if any, suspicions of blight. Rows 

 49 to 64. Well sprayed. No indications of blight. Rows 65 

 to 80. Well sprayed. No indications of blight. Rows 81 to 

 96. A few plants at extreme east with brown particles on leaves 

 but it does not look like blight. Last spraying not conspicuous 

 on the wet (with dew) leaves, but careful examination shows 

 that it is there. If there was no blight elsewhere, I should say 

 there was no reason to think there was any on this plot. Rows 

 97 to 112. Well sprayed. An occasional brown spot which may 

 be blight, but should not think so if it were not for blight else- 

 where. Rows 113 to 128. Pretty well sprayed. A few black 

 patches which look like blight on some of the lowest leaves. This 

 is especially the case at the east end where plants are rankest. 

 Rows 127 to 144. For three or four rods at west end many of 

 the lowest leaves are dead with blight. Some indications of 

 blight all alon°". Less in the middle and east except that for 1 

 rod at east end there are quite a number of dead leaves. Rows 

 145 to 160. Very little indication of blight except in west end 

 where a few leaves are dead or nearly so. Not nearly as bad as 

 west end of rows 129 to 144. Rows 161 to 176. Pretty well 

 sprayed. Very little if any indications of blight; should not be
