FARMERS BULLETIN 



Arsenic and Paris green are deadly poisons. Handle them with 

 qreat care. 



It is advisable to keep young children, live stock, and chickens 



away from this bait. 



In severe attacks by cutworms on 

 loAv-growing plants, such as parsley, 

 a lead-arsenate spray will answer 

 in place of the bait. 



Clean cultural methods and crop 

 rotation are advisable, as are also 

 deep fall plowing and disking, to 

 prevent recurrences of cutworm at- 

 tacks. Experienced growers become 

 expert in detecting cutworms and 

 remove them by hand. This often 

 can be done with profit on small 

 patches.

WmTE GRUBS. 



When new land is used for plant- 

 ing vegetables, especially land that 

 has been in sod or grown up with weeds, white grubs are almost 

 certain to make their appearance, sometimes in large numbers, doing 

 great damage to plants from the time they attain any growth until 

 the fruit is ready for harvest. They feed chiefly on roots and attack 

 especially potatoes, corn, and strawberries, but they are general 

 feeders. "Wliite grubs, or 

 " grub worms," are the larvae 

 or young of the brown May 

 or June beetles, with which 

 most persons are familiar. 

 (Fig. 11.) The beetles occur 

 in the North as late as Au- 

 gust, while in the South they 

 appear in April or earlier. (. 



Control. — Deep plowing is 

 the most effective remedy for 

 white grubs. Cross plowing and deep disking are sometimes neces- 

 sary, and the ground should be disturbed often and kept clean of 

 weeds so that the grubs can be eliminated. 



Rotation of crops, avoiding the planting of potatoes, beets, sweet 

 corn, and other crops on land which has been for some time in the 

 same crops or in strawberries, grasses, or weeds is advisable. Fer-
