INSECT PESTS OF CIGAR-TYPE TOBACCOS oil 
free-flowing carrier. Finely ground, sterilized tobacco dust has 
been found satisfactory for this purpose. The barium fluosilicate 
and the tobacco dust are mixed in the proportions of 8 parts by 
weight of the poison to 2 parts of tobacco dust. Applications of the 
mixture should be made at the rate of from 4 to 6 pounds per acre. 
The poison mixture when evenly applied at this rate should be safe 
on newly set tobacco plants. The use of this insecticide on large 
tobacco is not recommended, however, since it may cause burning or 
discoloration of the leaves under certain weather conditions. 
Paris green in the dust form may be used to control flea beetles on 
newly set tobacco. While the poison is quite toxic to the insect, it

CAUTION: Operators of hand dusters should protect the body with aprons

CUTWORMS 
Although cutworms are considered one of the minor tobacco pests 
in the South, they are present, under certain conditions, in sufficient 
numbers to cause serious damage. With the exception of the damage 
produced by climbing forms, the injury invariably occurs in the 
spring in plant beds or on newly set tobacco. The injury consists 
in the cutting off of young plants near the surface of the ground 
and in the devouring of the leaves (fig. 35). The resetting of plants 
adds to the expense of growing the crop and is frequently unsatis-
