and lime. Definite conclusions could not be drawn, but it seemed 
that the efficiency of the sulphur was somewhat increased by the 
addition of lime. 
During the last three years the experiments were so planned as 
to show three things: (1) The increase in yield due to the use of 
sulphur and lime applied in the drills; (2) whether injury to the 
crop may result from the accumulation of sulphur in the soil 
through repeated applications of the treatment; (3) whether lime 
and sulphur applied broadcast are as effective as when applied in 
the drills. The conclusions reached were as follows: “ There seems 
to be no doubt that onion smut can be prevented to a considerable 
extent, but not wholly, by the application of sulphur and air-slaked 
lime in the drills at time of sowing the seed. What quantity of 
sulphur and lime it is best to use has not been definitely determined, 
but in our experiments excellent results have been obtained from 
the use of 100 pounds of sulphur to fifty pounds of lime (equal 
parts by measure) per acre. We recommend the use of this quan- 
tity until it has been shown by experiment that some other quantity 
gives better results. 
“There is no danger of harmful results from the accumulation of 
sulphur in the soil, provided it is not used in excessively large 
quantities. Broadcast applications of the sulphur and lime have 
little if any effect on smut; the application must be made in the 
drills.” 
The results of these experiments show plainly that the sulphur- 
lime treatment is a practical and profitable remedy for onion smut. 
Yet Orange County onion growers have made no use of it. So far 
as they are concerned the expense of the experiment was absolutely 
wasted. 
The only other onion disease studied by the Station is a bacterial 
rot common in Orange County in 1898. It appears to have been 
brought about by the excessively wet weather during July and 
August of that year. Thorough drainage and clean cultivation 
are recommended as preventive measures. 
PEACH. 
Although several peach diseases have received more or less at- 
tention at the Station, an extended investigation has been made 
of none of them.
