PEANUTS 



(1) Pre -emergence. --For control of annual grasses and broadleaved weeds, such as 

 crabgrass, pigweed, lambsquarters, morning glory, cocklebur, and others: DNBP at 6 

 to 8 pounds in 10 to 20 gallons of water per acre applied during the planting operation 

 or any time after planting and prior to emergence. Will not control such perennial 

 weeds as nutgrass, Johnson grass, and Bermuda grass. The treatment is often not 

 effective in controlling deep germinating seedlings of cocklebur and other annuals, 



Z,4-DES at 3 pounds in 20 gallons of water per acre has proved effective in con- 

 trolling annual grasses and broadleaved weeds in peanuts. 



Comments and precautions . --Both DNBP and 2,4-DES may cause some injury to 

 peanuts on light sandy soils if heavy rains following application leach herbicides into 

 zone of germination. If average daily temperatures are 88° F. or higher from time 

 of application to emergence of crop, DNBP compounds will volatilize. This will reduce 

 the effective period of weed control, and the vapors may injure germinating peanut 

 plants. Effectiveness of 2,4-DES is reduced if prolonged drought follows application. 

 Where 2,4-DES or other herbicides are used, peanuts should be planted as deeply as 

 feasible to minimize herbicide injury. 



RICE 



(1) Post-emergence . --For control of coffeeweed and other broadleaved weeds: 

 Amine salt formulations of2,4,5-T, MCPA, or 2,4-D at 1/2 to 1 pound in 5 to 20 gallons 

 of water applied any time after rice is well tillered but prior to jointing or reaching 

 boot stage. Will not control annual or perennial grasses. The rice plant is sensitive 

 to 2,4,5-T, MCPA, and 2,4-D in the early seedling, boot, and early heading stages. 

 Applications at these stages should be avoided unless heavy weed infestations seriously 

 threaten the crop. If applications are necessary during sensitive stages of growth, use 

 minimum rate required to control the weeds. 



Comments and precautions . --Cotton, soybeans, and other crops sensitive to 

 2,4,5-T, MCPA, and 2,4-D may be seriously injured by vapors or spray drift from 

 these herbicides. These three herbicides rank as follows according to their toxicity 

 to cotton, with the least toxic first: 2,4,5-T, MCPA, and 2,4-D. Several esters of 

 these three herbicides are highly volatile while others are much less volatile. In 

 cotton producing areas, use only amine salt or low volatile ester formulations to 

 control weeds in rice. Avoid application when wind direction is toward cotton or 

 other susceptible crops. In certain States it is not permissible to use esters of the 

 phenoxy compounds. State regulations should be complied with in all cases. 



SUGAR BEETS 



(1) Preplanting .--For control of wild oats and other annual grasses and some broad- 

 leaved annual weeds: IPC at 3 to 6 pounds in 10 to 40 gallons of water per acre applied 

 to surface of soil and thoroughly disked into soil surface 2 to 4 weeks before planting. 



(2) Pre -emergence . --For control of most annual grasses (except wild oats) and some 

 broadleaved weeds: TCA at 5 to 7 pounds in 10 to 20 gallons of water per acre just 

 prior to emergence of beets. 



Several herbicides have been studied in localized areas as pre-emergence sprays 

 to control weeds not controlled by TCA. These treatments have involved an evaluation 

 of the use of dalapon at 4 to 8 pounds, PCP at 6 to 10 pounds, IPC at 3 to 6 pounds, and 

 DCU at 6 to 24 pounds per acre. Rates of applications have varied considerably,
