A SO-CALLED BLIGHT CURE. 
BY CARL H. POTTER, 
The “Woodbury Blight Cure” as its name implies, is a 
proprietary article that has recently been placed on the 
market. This “cure” is guaranteed to be a certain remedy 
for the blight of apple and pear trees if used as directed, 
and a destroyer of insect pests as well. Two mixtures are 
sold by the company controlling the cure, a body wash and 
a summer spray. The claims for the remedies and the di¬ 
rections for their use, as set forth by the company, are as 
follows: * 
‘‘The body wash should be used at least once during the season, prefer¬ 
ably early in the spring on account of sun scald, but of immense benefit any 
time in the year. 
“The summer spray should be used at least three times during the 
season for the cure of the blight and the destruction of insect pests. It should 
be used after, or during, every severe electrical storm for an insurance 
against the twig blight. 
“Spray the first time when the trees begin ‘o leaf, again from the mid¬ 
dle to the last of July. Follow these directions carefully, and we will guar¬ 
antee a cure for blight and the practical destruction of the codling moth and 
other injurious insects. The spray is beneficial and will promote a strong, 
healthy growth in all plant life, more especially on roses and vines. It will 
destroy slugs and green flies in the green-house.” 
On account of the fact that a large sale of such cure 
had been made, and that many inquiries had come to the 
Station, it seemed proper for a trial to be made. 
June 29, 1898, a number of bearing apple trees in the 
Station orchards were selected and prepared for trial. 
Eour distinct series or lots of trees were treated, while the 
others, as similar as it was possible to select them, were 
wholly untreated. These entered the test merely as checks 
with which to compare the trees that were treated. All of 
the trees to which the remedies were applied were recorded 
as class “A,” while the untreated, or check trees, were 
class “C.” 
The different series of trees comprised summer, fall, 
and winter apples, and varied from very slight affection of 
the twigs to quite severe cases of blight, in which many of 
the smaller limbs were entirely diseased, the blight even 
forming large and more or less concentric patches on the
