(3) Post -emergence . --For control of most broadleaved annual weeds in all 

 pea-producing areas: Amine salt of DNBP at 3/4 to 1-1/4 pounds in 20 to 40 

 gallons of water per acre applied when weeds are small and peas are 3 to 8 

 inches tall. 



For control of annual broadleaved weeds in North Central States : 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. These will inhibit groAvth 

 of Canada thistle and other perennial weeds, and control them under some 

 conditions. 



Connments and precautions . --When using DNBP connpounds, apply low^er 

 rates in the range if temperature is over 70°F.; use higher rates if tem- 

 perature is lower than 70°F.; avoid application if temperature is 85°F., or 

 higher. 



Potatoes 



(1) Preplanting. --For control of nutgrass and annual broadleaved weeds and 

 weed grasses: EPTC at 4 to 8 pounds in 20 to 40 gallons of water per acre. 

 Incorporate immediately after application by disking or suitable cultivation. 

 Granular formulations are also effective. 



For control of quackgrass: Dalapon at 10 pounds applied in 20 to 40 gallons 

 of water per acre. 



(2) Pre -emergence . - -For control of germinating annual broadleaved Aveeds 

 and w^eed grasses: DNBP amine salt at 3 to 4-1/2 pounds or sesone at 3 to 4 

 pounds in 20 to 40 gallons of water per acre applied just before emergence of 

 potatoes. 



For control of annual grasses: Apply dalapon at 3 pounds in 20 to 40 gallons 

 of water per acre just before potatoes emerge. 



For control of quackgrass: Apply dalapon at 7-1/ 2 pounds per acre after 

 grass ennerges but before potatoes emerge. 



(3) Post -emergence . --For control of germinating annual grasses, lambs - 

 quarters, and pigAveed: Sesone at 3 to 4 pounds in 20 to 40 gallons of water per 

 acre applied immediately after clean cultivation at lay-by. 



For control of growing quackgrass: Apply dalapon at 10 pounds in 20 to 40 

 gallons of water per acre. 



Sweetpotatoes 



(1) Transplanting -time . - -For control of annual grasses and important broad- 

 leaved weeds: NPA imide at 2 to 3 pounds in granular form per acre after 

 setting the plants. Use lower rate on sandy soil. 



(2) After Last Cultivation . --For control of annual grasses and important 

 broadleaved weeds: NPA imide orClPCat2to3 pounds in 40 gallons of water 

 per acre after last cultivation. Use lower rate on sandy soils. 



Comments and precautions . - -Apply treatments only when soil is moist 

 enough for rapid w^eed seed germination.
