at 3/4 to 1-1/2 pounds or NPA at 4 to 6 pounds in 40 gallons of water per 

 acre applied on soil surface between rows and on bases of cotton stalks 

 in the row just before, or after, the last cultivation. NPA has not been as 

 consistent in controlling annual morning-glory as monuron and diuron. 



Comments and precautions . --These treatments are suggested only 

 for use under the irrigated conditions of the Western cotton producing 

 area. Residual activity of urea herbicides (including monuron and diuron) 

 on crops following cotton in a rotation is being investigated. Available 

 information indicates small grains planted after cotton that has been 

 treated with monuron or diuron may be seriously injured by residual 

 activity of these herbicides. Crops that are more tolerant to urea 

 herbicides, such as grain sorghum or cotton, should be planted the 

 spring following cotton that has been treated with monuron or diuron 

 for weed control. 



SOYBEANS 



Pre -emergence .- -For control of annual weeds, such as crabgrass, fox- 

 tail, giant foxtail, pigweed, lambsquarters, morning-glory, cocklebur, and 

 others: DNBP at 4 to 8 pounds or PCP at 18 to 24 pounds in 10 to 20 gallons 

 of water per acre applied immediately after planting. Deep germinating 

 annuals are usually less likely to be controlled than shallow germinating 

 weeds. Perennial weeds, such as nutgrass, quackgrass, Johnsongrass, 

 Canada thistle, and milkweed are not controlled. To reduce the cost of 

 chemical weed control in soybeans, "band treatments" may be applied as 

 described for cotton. 



Comments and precautions .- -If heavy rains follow application before 

 crop emergence, treatment may injure soybeans. If prolonged drought 

 follows application, weed control may be erratic. DNBP compounds pro- 

 duce vapors toxic to soybean seedlings if temperatures of 88° F. or 

 higher prevail for 5 to 10 days following treatment. Temperatures of 

 90° F. or higher cause rapid evaporation of DNBP, and may greatly 

 reduce the period of effective weed control. 



PEANUTS 



Pre-emergence .--For control of annual grasses and broadleaved weeds, 

 such as crabgrass, pigweed, lambsquarters, morning-glory, cocklebur, 

 and others: Sesone at 3 pounds in 20 gallons of water per acre or DNBP 

 at 6 to 9 pounds in 10 to 20 gallons of water per acre applied during the 

 planting operation or any time after planting and before emergence. Will 

 not control such perennial weeds as nutgrass , Johnsongrass, and Bermuda- 

 grass. The treatment often is not effective in controlling deep germinating 

 seedlings of cocklebur and other annuals. 



Comments and precautions. --Both sesone and DNBP may cause some 

 injury to peanuts on light sandy soils if heavy rains following applica- 

 tion leach herbicides into zone of germination. Effectiveness of sesone 

 is reduced if prolonged drought follows application. Where sesone or 

 other herbicides are used, peanuts should be planted as deep as feasible 

 to minimize herbicidal injury. If average daily temperatures are 88° F., 

 or higher, from time of application to emergence of crop, DNBP com- 

 pounds will volatilize. This will reduce the effective period of weed 

 control, and the vapors may injure germinating peanut plants.
