fi es rate of 1 gal. to 80 or 100 square feet. 
For best results and most economical use, apply early when vegetation is 
young and tender. 
If dry application is preferable, use % lb. to every 35 square feet and ,if 
season is dry, wet down area lightly with water after applying. 
TOXIC TO ALL VEGETATION TO KILL PERENNIAL WEEDS 
. Perennials are best treated when nearing maturity or dormant stage; spring 
NONSELECTIVE applications may be made also. Summer applications are not normally rec- 
ommended... rainfall is essential for best results on deep-rooted weeds. For 
FAST-ACTING SPRAY application: add 1 lb. to a gallon of water and spray 1 to 1% gallons 
per 50 square feet on average vegetatoin.

BORASCU destroys weeds Easy ip Use 
and grassed easily, econamically : / 
Useful About Buildings, Fence Lines, and other areas where 
a bare surface is desirable . . . or for noxious weed control 
BORASCU is a safe, economical, and effective weed and grass-killing chemi- 
cal when used properly. Since this chemical is non-selective, being toxic to 
most types of vegetation, it should be used only where a bare surface is 
desired. Effects on adjoining soil or vegetation should not occur if normal 
care is taken to confine the BORASCU treatment solely to those specific 
areas under control and where roots of adjacent vegetation do not extend 
into treated area. BORASCU is applied in its delivered form and may be 
handled freely for it is non-poisonous and non-combustible; neither will it x 
corrode ferrous metals. Applied in dry form, BORASCU must be dissolved 
(usually by seasonal rains) and carried into the soil to become effective. Con- 
trol will continue effective until normal leaching takes the BORASCU below 
® 
the layer of soil in which root growths usually occur. Under favorable con- 
ditions, results may last for two years or longer. 
Apply Borascu during Fall, Winter, or early Spring months for best re- 
sults. LATE SPRING AND SUMMER APPLICATIONS are not recom- 
mended as rains during that period are irregular, and may be in the form 
of heavy thunderstorm which could cause loss of material through wash-offs. 
In general, apply BORASCU before plants appear or when they are young WEED «i Serie 
and tender and more susceptible to chemical action.

applications may be made). WINTER ANNUALS: Apply in fall or winter. A’20 MULE TEAM’ P PRODUCT
