or fall application is favored, as it gives the grass a 
better chance to fill in the bare places. On turf 
areas where bent grass is predominant, use the min- 
imum amount for control. Where clover is maintain- 
ed, use the minimum amount suggested; although the 
flowering will be inhibited, most of the clover 
will survive the treatment. Most of the seedling 
grasses are sensitive to 2,4-D, so it is suggested that 
spraying be delayed until the root systems are well 
established and a sod has been formed. For the 
control of crabgrass, use 4 pints of WEEDAR 64 or 
5 pints of WEEDONE CONCENTRATE 48 per acre, 
applying it before the crabgrass seeds germinate. 
(b) For the control of turf weeds in seed grass crop, use 
(c 
— 
% to 2 pints of WEEDONE CONCENTRATE 48 or 
1 to 3 pints of WEEDAR 64 appliec per acre de- 
pending on the susceptibility of the weeds. Use these 
sprays after the young grass seedlings have estab- 
lished roots and formed sod or before the boot stage. 
For control of weeds in spring wheat, barley, rye, 
oats, use 4% to %, pints of WEEDONE CONCEN- 
TRATE 48 or % to % pints of WEEDAR 64 per acre 
for the control of such weeds as mustards, French- 
weed, marshelder, ragweed, sunflower, cocklebur, 
wild buckwheat, and hedge bindweed.-Apply at full 
tiller stage or when 6” high to early boot stage. On 
oats, wait until crop is 10” high. For the control of 
such resistant weeds as field bindweed, Canada 
thistle, sow thistle and similar weeds, apply 1 to 2 
pints of WEEDONE CONCENTRATE 48 or 
WEEDAR 64 per acre. 
(d) For control of annual weeds in winter wheat and 
(e 
— 
rye, apply 4% to 1% pints of WEEDONE CONCEN- 
TRATE 48 or WEEDAR 64 in the spring. 
For the control of weeds in corn, we suggest that 
you follow either pre-emergence or post-emergence 
treatment: 
For pre-emergence treatment of corn, apply between 
2 and 4 pints of WEEDAR 64 or WEEDONE CON- 
CENTRATE 48 per acre 4 to 8 days after the corn has 
been planted. This treatment is recommended for the 
control of grass weeds as well as broadleaf weeds in 
corn; it eliminated the need for cultivation on many 
farms last year. Until further research is reported, 
do not attempt pre-emergence treatment on light 
sandy soils. 
For post-emergence treatment of corn and sorghum, 
apply % to 1% pints of WEEDONE CONCENTRATE 
48 or WEEDAR 64 per acre after corn reaches 6” 
and before tasseling. Use the lowest recommenda- 
tion on the susceptible weeds like cocklebur, rag- 
weed, mustard, and sunflower, and the higher dosages 
on the more resistant perennials like the thistles, 
the nettles, and bindweed. Most corn varieties 
are more susceptible during the rapid growth stage, 
when about 10” to 30” high. If it is necessary to 
treat with the higher dosages during this stage of 
growth, it is advisable to place an extension on your
