depending on the weed species, soil type and available soil moisture, and several other 

 soil and climatic factors. 



(3) PQSt-ennergence. --For control of many broadleaved weeds on acid or neutral 

 soils in the humid regions: Sodium chloride at 200 to 300 pounds in 100 to 200 gallons 

 of water per acre applied when beets are in 2- to 4-true-leaf stage. Will not control 

 lambsquarters or purslane. In preliminary studies, dalapon at 4 to 6 pounds per acre 

 has looked promising as a post-emergence spray for the control of seedling weedy 

 grasses and certain broadleaved weeds in sugar beets. 



Comments and precautions . --Chemical weed-control practices in sugar beets vary 

 widely depending on weeds present and several soil and climatic factors. 



TOBACCO (PLANT BEDS) 



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

 tobacco plant beds: 1 pound of uramon and 1/2 pound of calcium cyanamide or 1 to 1-1/2 

 pounds of calcium cyanamide per square yard, or 1 pound of methyl bromide per 100 

 square feet of plant bed area. Applications of uramon-cyanamide or cyanamide alone 

 should be made in October in the mid -Atlantic States and thoroughly mixed in the upper 

 3 inches of soil by disking and raking. Methyl bromide is a volatile soil sterilant, and 

 the plant bed must be covered with a gas-tight cover for the chemical to be effective. 

 Methyl bromide may be used in the spring without residual toxicity to tobacco plants.
