attacks the fruit stems and hulls " cutting off the supply of nourish- 

 ment from the berries and disfiguring them bj the withering of 

 the calyx." 



When the spots first appear on the leaves they are of a deep 

 purple color, but later they enlarge and the center becomes gray or 

 nearly white. Portions of the infested leaves frequently assume 

 bright red tints and when badly diseased finally wither and die. 



Treatment. — Bordeaux mixture, 1 to 11 formula, used as advo- 

 cated by Hunn in the Annual Report of this Station, 1892 : 6S2, 

 gives beneficial results. When setting a new plantation be particu- 

 lar to remove the diseased leaves before taking the plants to the 

 field, or if the plants must he trimmed in the field the diseased 

 leaves should not be left where they can communicate the disease to 

 the new foliage as it grows out. The following treatment is then 

 suggested : 



Spray the newly set plants soon after growth begins and follow 

 with three or four treatments during the season as seems necessary. 

 The following spring spray just before blossoming, and again in 

 from ten days to two weeks. As soon as the fruit is gathered it is a 

 good plan to mow off the foliage of badly diseased beds and burn it 

 if the beds are to be fruited a second season. 



Ctkubs — The larvae of the May Beetle, a white grub, frequently 

 does much injurj'^ to strawberries by eating off the roots. It is said 

 that the insect lays its eggs chiefly in sod ground. These hatch into 

 the larvie or grubs which feed on roots of various plants till the 

 third year afterwards, when they come from the ground in the form 

 of May beetles. Since the grubs live in the ground till the third 

 season after the eggs are laid, it is a good practice not to use land 

 for strawberries till the third 3^ear after it was in the sod.

Bean. 



Anthracnose. — In many parts of the State the bean crop is 

 severely injured by a disease known as anthracnose. It attacks the 

 bean plant in all stages of its growth, and survives the winter in the 

 beans themselves. The badly diseased beans can be readily told by 

 the discolorations, which vary in size from a small spot to large 

 pits and blisters. When such seed is planted the fungus begins to
