three of these fields. Ergot caused by Claviceps purpurea was reported 
from 15 fields but was not nearly as prevalent as in 191S. 
Pipal reports that anthracnose, caused by Colletotrichum cereal was ser- 
ious in southern Indiana. The disease was also found in Cass County. 
Scab caused by Gibberella saubinetii was found in 24 or 85% of the 28 
fields above mentioned, with an average incidence of 54% and a maximum 
of 40%. In addition, the disease was found in two counties not included in 
that survey. 
Leaf rust (Puccinia dispersa) was found in nine of the 28 fields with an 
average incidence of 4.4% and a maximum of 45%. It is quite likely, 
however, that leaf rust occurred to some extent in all fields. Mains reports 
that leaf rust was very severe on rye cover crops late in the fall of 1918. 
citing one case near Logansport where a field was quite yellow with the 
rust. Stem rust (Puccinia graminis) was found in 5 fields with an average 
incidence of less than 1% and a maximum of 15%. 
Stem smut caused by Urocystis occulta was found to a very limited ex- 
tent in Lake and St. Joseph counties. One head of loose smut was found 
in the latter county by Gregory.

Rust (Puccinia antirrhini) is steadily increasing in prevalence in Indiana, 
according to H. S. Jackson. 
STRAWBERRY. 
Leaf-spot caused by Mycosphaerella fragariae was very generally found 
in all plantings but was not especially destructive since its attack did not 
become severe until after the fruit was picked. Pipal reports that the 
disease was prevalent in the commercial crop at Borden, Clark County. 
SWEET Poraro. 
Black rot due to Sphaeronema fimbriatum occurred in Jay County where 
it caused losses on several farms. 
TOMATO. 
Leaf-spot cau-ed by Septoria lycopersici was the most important disease 
of field tomatoes and was present in almost all fields to a greater or less 
degree. This disease usually does not become destructive until late in the 
season. By killing the lower leaves the disease not only reduces the leaf 
area of the plant but exposes the fruit to sunseald. Tests with copper 
sprays conducted by W. B. Clark of the U. S. Bureau of Plant Industry 
at Paoli indicate that leaf-spot may be held in check to some extent but 
not satisfactorily controlled by spraying. This is largely owing to the 
impossibility of thoroughly covering the foliage after the plants become 
large. Increases in yield were secured by spraying, however. Leaf-spot 
was much worse in the region near Paoli than in the Indianapolis region. 
The disease was found to some extent in greenhouses near Indianapolis. 
Early blight caused by Alternaria solani occurred to some extent in 
plant beds causing a leaf-spot and also an elongated, blackened stem
