PURE PARA-DICHLOROBENZENE 

 For Peach Borer Control. 



Very powerful and effective remedy just 

 coming into general use as a result of the 

 experiments of the Department of Ento- 

 mology. Should be applied September 1st 

 to October 10th, according to latitude. 

 Some growers prefer to make two applica- 

 tions, the first being in the month of Juhe. 

 One pound is sufficient for 10 to 30 trees, 

 according to size. It is not advisable to 

 treat tre^s under 4 years of age with Para- 

 Dichlorobenzene, and apple trees should 

 never be treated. 



Remove all grass, weeds and rubbish from 

 around the tree, make a smooth, bare sur- 

 face and about sixteen inches wide around 

 the tree at the soil level. 



Remove any gummy exudation ahering 

 to the crown or collar of the tree. 



After the ground is prepared, distribute 

 the crystals of Para- Dichlorobenzene even- 

 ly in a narrow circular band around the 

 tree, keeping the inner edge of the band at 

 least two inches away from the bark of the 

 tree. 



After the crystals are placed on the. soil 

 around the tree cover them with earth, at 

 first lightly so as not to disturb the chemi- 

 cal^ and complete by monuding the earth 

 against the trunk of the tree until a cone 

 shaped mass of dirt four or five inches deep 

 has been made, tamping the dirt down with 

 the back of the shovel. 



Use one ounce to a tree 6 years old or 

 older; in case of very large tree, 1^2 ounces 

 may be needed to form a satisfactory band. 

 On trees four or five years old, use ^ to 24 

 ounces to a tree.

 tionized seed disease treatment and repre- 

 sent the most remakable advancement of 

 the century in scientific agriculture. 



Semesan — The only chemical that can 

 be applied in either the liquid or conve-

 parasitic diseases and fungoid growths 

 borne by seeds, bulbs and seed pieces. 

 Semesan controls diseases such as "Damp- 

 ing-Off," "Brown Patch" and "Crow-n 

 Gall," and is just as effective for flower and

 trolling diseases of similar roots and tubers 

 fo other vegetables and flowers. Semesan 

 Bel exerts an invigorating effect upon plant 

 growth by removing disease handicaps and 

 repelling the attacks of soil-borne organisms 

 so that yields are greatly increased. Ask

 spray. Applied 'in the fall it controls scale 

 of all kinds, bud-moth, pear psylla, peach 

 leaf-curl, and fungous cankers. The delay- 

 ed dormant 'spray with Scalecide controls 

 scale, aphis, pear thrips, leaf miner, case 

 bearer, leaf roller, European red mite, bud- 

 moth, ahd fungous cankers. And in addi- 

 tion year after year use of Scalecide in- 

 vigorates the trees. Scalecide is guaran- 

 teed to make a better ordhard than^lime- 

 sulfui. 



Scalecide is pleasant to use; it does not 

 injure even the eyes. It is non-poisonous.. 

 It saves half the labor of spraying — a tank- 

 ful of dilute Scalecide goes as far as two 

 tankfuls of dilute lime-sulfur. Scalecide 

 saves the cost of nicotine; saves the cost of 

 spreader; saves more than three-fourths 

 the freight and haulage. A fifteen-gallon 

 dru m of Scalecide covers the same trees as a

 tremely fine sulfur in its most active fungi- 

 gicidal form. Prices— Pt., 70c; qt., $1.00;
