 fiehls ahove mentioned, with an av(>rafr(> inciihMice of ~)A''t and a niaxinnini 

 of 40%. In addition, the disease wa>; found in two cmuilies not inchuled in 

 that survey. 



Leaf rust {I'nrcinia disiHrsa) was found in nine of the lis lields with an 

 average ineidence of 4.4% and a niaxiniuni of hl'r. It is (piite likely, 

 however, that leaf rust occurred to some extent in all lields. .Mains repurts 

 that leaf rust \vas very severe on rye cover crops late in the fall of r.tis, 

 citini,' one case near Loyans]iort where a Held was quite yellow with the 

 rust. Stem rust { rii<<iiii<i anniiiiiis ) was foinid in fi fields with an a\-era^'e

Leaf-spot can eil hy Scplorin h/copirsici was the most important disease 

 of tield tomatoes and was present in almost all fields to a greater or less 

 degree. This disease usually does not l)econie destructive until late in the 

 season. I'.y killing the lower leav(\s the disea.se not oidy reduces the leaf 

 area of the plant hut exposes the fruit to sunscahl. Tests with copper 

 sprays conducted hy AV. B. Clark of the IT. S. r.iireau of IMaut Ind\istry 

 at I'aoli indicate that leaf-spot may he held in check to some extent hut 

 not satisfactorily controlled hy spraying. This is largely owing to t he 

 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 Indianapoli-; region. 

 The disease was fonnd to some extent in greenhouses near Indianapolis.
