Fire Blight 
Blighted twigs and cankers should be carefully removed when 
pruning is done during the dormant season. If a little blight 
appears during the summer it may be stopped by cutting out 
affected twigs. Cut several inches below the visible blight and 
remove the twig without brushing it against others. Sterilize 
the shears in corrosive sublimate solution. If there is a lot of 
blight the growth of the tree should be slowed by putting in a 
cover crop to uSe excess moisture. Write for leaflet. 
Sunscald 
Sunscald is a type of winter injury that appears as cankers 
on the south or southwest side of trunk or limbs. Anything 
that will keep the sun from shining directly on the trees during 
the winter will help to prevent sunscald. Wrap the trunk 
and lower main limbs with aluminum foil, (Such as is used 
in frozen food storage.) 
Dandelions 
Apply 2,4-D spray (as directed by manufacturer) in the 
morning of a clear day when the temperature is above 70 
degrees F. One application early in the season should keep 
the lawn relatively free for the remainder of the season. 
Later sprays may be applied if necessary. (Warning—keep 
away from garden plants and shrubbery.)

Pocket Gophers 
Cut potatoes or carrots into 14-inch pieces. Dust lightly 
with mixture of % ounce sodium bicarbonate, % ounce 
powdered strychnia alkaloid, 1/80 ounce saccharine, Place

Rabbits 
Wrap the trunk and lower main limbs of young trees 
with aluminum foil. (Such as is used in frozen food storage. ) 
A repellent paint prepared by dissolving 134 pounds of pow- 
dered rosin in 1 quart of ethyl alcohol is fairly effective when 
applied to the trunks and main branches of trees. 
Mice 
Protectors made of % or % inch mesh galvanized wire 
placed around trunk of orchard trees at base will help pre- 
vent girdling by mice and rabbits. Remove weeds and grass 
from base of trees and mound earth around trunk. Write to 
Horticultural Society, University Farm, St, Paul 1, Minn., for 
information on control of mice in orchards with poison grain 
and cost of poison grain available through the society.
