Buckeye rot due to Phytophthora terrestria was noted in three green- 
houses near Indianapolis. Only the lower fruits were infected and it is 
evident that infection was the result of splashing from the soil underneath. 
In one ease the rotting fruits were picked off and thrown on the ground thus 
affording the fungus every opportunity to develop and spread to other 
fruits. Strict sanitation should of course be practiced in attempting to con- 
trol this disease, 
Blossom-end rot was very destructive in both the greenhouse and field 
‘crops on the early set of fruit and in the Lafayette region where the soil 
dries out very quickly the disease continued to be prevalent well into the 
season. In fields near Lafayette. H. D. Brown reports a loss of three tons 
per acre of green fruit actually removed because of this disease. This 
loss is appalling when one considers that the final yield was but eight tons 
per acre. 
In the canning crop growth cracks probably occasion more loss in the 
aggregate than all the parasitic diseases combined and this trouble is 
about equal to blossom-end rot as a source of loss. Not only are growth 
eracks an objectionable blemish in themselves but most of the fruit rot 
late in the season in the canning crop both in the field and in the erates 
is due to the infection of these growth eracks by rot-producing organisms. 
Growth cracks cause heavier losses to the canner than to «he grower since 
much of the fruit rot occurs after picking, whereas the loss due to blossom- 
end rot falls largely upon the grower. | 
Sunséald was very common owing to the foliage destruction by Septoria 
leaf-spot and consequent exposure of the fruit. Catface was very prevalent 
in the canning crop and is an objectionable blemish from the canner’s stand- 
point. According to Dr. B. J. Howard of the Federal Bureau of Chemistry, 
the eatface sears are prone to crack and permit rot infection. 
A peculiar type of non-parasitie wilting of the plants occurred in the 
Paoli region and.at Lafayette. Affected plants showed the hollow stem 
condition, the pith having dried out and collapsed even in the very young 
shoots. At Lafayette the affected plants were near a row of trees along 
the edge of the field and a similar relation was reported from Paoli so if is 
possible that this hollow stem wilt was due to soil drouth produced by the 
tree roots. 
A small, circular, conspicuously white, raised spot with a darker center 
occurred rather commonly on tomatoes about Lafayette and Indianapolis. 
This has been called “white spot” or “bird’s-eye spot” and is often assovi- 
ated with bacterial spot. Probably it is due to an insect injury. 
A Sclerotinia stem rot was found on a few greenhouse plants following 
wounds and wilt infection. Wind scalding of the leaves was noted at 
Hammond July 27. Hail injury was conspicuous on fruits and stems in the 
Indianapolis region July 17. 
From the standpoint of disease introduction the importation of tomato 
plants grown in the south for the Indiana canning crop is distinctly 
dangerous. Evidence of the introduction of Fusarium wilt into fields with 
southern plants was secured. Wholesale nematode infestation of the 
roots of the seedlings was found in shipments from several points in the 
south. Infested plants lived throughout the season when set out in Indiana 
fields but were stunted and below normal in yield. The galls on the old
