Peas 



(1) Preplanning . --For control of wild oats and other grasses in Inter- 

 mountain region: IPC at 3 to 6 pounds in 10 to 40 gallons of water per acre 

 applied to the soil, and thoroughly disked into soil surface 2 to 4 weeks 

 before planting. 



(2) Pre -emergence . --For control of annual weeds inNortheasternStates: 

 Any one of several amine salts of DNBP at 4 to 6 pounds in 10 to 20 gallons 

 of water per acre. 



(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. Will inhibit 

 growth 67f Canada thistle and other perennial weeds, and control them under 

 some conditions. 



Comments 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. 



Irish Potatoes 



Post- emergence .- -For control of annual grasses, lambsquarters, and 

 pigweed: Sesone at 3 to 4 pounds in 40 gallons of water per acre after the 

 last cultivation. Granular applications appear to be as effective as sprays. 



Sweetpotatoes 



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

 broadleaved weeds: NPA, imid formulation, at 2 to 4 pounds in 40 gallons 

 of water per acre after setting the plants. Use lower rate on sandy soil. 

 Granular forms appear to be as effective as spray forms. 



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

 broadleaved weeds: NPA, imid formulation, or CIPC at 2 to 4 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 weed seed germination. 



Sweet Corn 



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

 grasses: Low-volatile ester of 2,4-D at 3/4 to 1 pound, 2,4-D amine salt 

 at 1 to 1-1/2 pounds, DNBP at 4 to 8 pounds, or PCP at L2 to 20 pounds in 

 20 to 40 gallons of water per acre. Effective 4 to 6 weeks after treatment. 



(2) Post- emergence . --For control of sensitive broadleaved weeds: Amine 

 salt of 2,4-D at 1/4 to 1/2 pound or the 2,4-D ester at 1/8 to 1/4 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 grasses.
