benefit hasbeen and can be derived from the spraying of arsenites 
for the extermination of insects injurious to fruits, ingludws the — 
eurculio. 
SPRAYING FUNGICIDES. 
But very little could be accomplished in this line of work the | 
present season. Owing to the extended wet weather the applica- 
tions made for the scab on the apple and pear gave negative 
results, and the only benefit derived was in spraying the grapes 
attacked with the downy mildew. 
On June thirtieth this fungus made its’ ‘appearance on the bearing 
vineyard. A spray of sulphide of potassium and water of the 
strength of one-half ounce of the sulphide to a gallon of water 
was applied to one-half of each vine. As the atmospheric condi- 
tion seemed favorable to the growth of the fungus at the time 
when its first appearance was noticed, a rapid spread of the 
disease over the whole vineyard was looked for. 
Such was not the case, however, and the greater part of the 
vines and fruit remained healthy. The application was repeated 
on July third, as rain fell soon after the first spraying, and the 
vines were treated for the last time on July tenth. As has been 
stated, observations were confined to a small percentage of the 
vines, but the benefits were marked in all cases where the disease ~ 
fastened itself, amounting in some varieties to fifty per cent of the — 
crop saved, that was attacked by the mildew. 
To Wuat Extent Dors THE CurRcULIO EAT THE FRutIT? 
In looking through the plum orchard, it was noticed that many 
of the fruits were disfigured by having one or more irregular holes 
or pits, eaten in the sides, supposed to be the work of the cur- 
culio. To verify this supposition and obtain more definite data 
in regard to the amount of injury that might be done by one 
individual, the experiment was made. 
On June eleventh a curculio was placed in a bottle with a green - 
plum and left until June fourteenth, when it was taken out and | 
examined. It was found literally covered with the crescent- 
shaped marks indicating the presence of the eggs, and two holes 
had been eaten in the side of the fruit, very close together, either 
one of which was large enough to have buried the curculio out of © 
sight.
