For control of annual broadleaved weeds in North-Central region: Amine or sodium 

 salt of MCPA at 1/8 to 1/3 pound in 5 to 20 gallons of water applied when weeds are 

 small and peas are 3 to 8 inches tall. Will inhibit growth of Canada thistle and other 

 perennial weeds, and control them under some conditions. 



Comnnents and precautions . --When using DNBP compounds, apply lower rates in 

 the range if temperature is over 70° F.; use higher rates if temperature is lower 

 than 70° F. Avoid applications if temperature is 85° F. or higher. 



Potatoes 



(1) Pre -emergence . --For control of broadleaved annual weeds and annual grasses: 

 DNBP at 3 to 6 pounds, PCP at 10 to 20 pounds, or TCA at 8 to 10 pounds in 20 to 40 

 gallons of water per acre applied following blind cultivation and prior to emergence of 

 potatoes. 



Spinach 



(1) Pre -emergence, early spring planting. --For control of annual grasses and many 

 broadleaved weeds: CIPC at 1 to 2 pounds on sandy soils, 4 to 6 pounds on heavier 

 nnineral soils, and 6 to 8 pounds on muck soils, in 10 to 20 gallons of water per acre. 

 When temperatures are higher and the loss of CIPC through volatilization is greater, 

 CIPC as a pre -emergence spray should be applied at 4 pounds per acre on sandy soils 

 and 6 pounds per acre on heavier mineral soils. The lowest rates in the suggested 

 range should be used when temperatures are 60° F.or less, and the higher rates when 

 temperatures are above 60° F. Results have varied widely with soil and climatic con- 

 ditions. 



Comments and precautions. --In the Mississippi River delta and some other agri- 

 cultural areas, fall-planted spinach may be seriously injured by CIPC at rates 

 required to control weeds. 



Sweet Corn 



(1) Pre-emergence. --For control of annual broadleaved weeds and grasses: Low 

 volatile ester of 2,4-D at 1-1/2 to 2 pounds, DNBP at 4 to 8 pounds, or PCP at 12 to 20 

 pounds per acre. Effective for 4 to 6 weeks after treatment. 



(2) Post-emergence .--For control of sensitive broadleaved weeds: Annine salt or 

 ester of 2,4-D at 1/4 to 1/2 pound in 5 to 20 gallons of water per acre applied when 

 weeds are small and while corn is 4 to 12 inches tall. Does not control grassfes. 



Comments and precautions . --Follow those given for weed control in field corn. 

 Pre-emergence applications of 2,4-D, however, may result in some injury if applied 

 to shallow-planted stands (1/4 to 1/2 inch). 



Watermelons 



(1) Pre-emergence and post-emergence. --Same as for cantaloupes and muskmelons. 



SMALL FRUITS 



Brambles (Raspberries, Blackberries) and Blueberries 



(1) For control of weeds In early Spring In brambles grown in the hedge or linear 

 system: First application- -2, 4-DES at 3 to 6 pounds or an amine salt of 2,4-D at 1/2 

 to 1 pound In 20 to 40 gallons of water per acre. DNBP at 2 to 4 pounds In 20 to 40 

 gallons of water per acre should be applied prior to emergence of weeds or new canes.
