Weevil : Ad ults lav eggs 

 in the pods in the field and 

 keep on breeding in the 

 dried seed, finally ruining it 

 for planting or for food.

 using about two fluid ounces

 the seed in a tightly-covered 

 barrel will kill the weevils 

 Bean Weevil without injuring the beans 

 for food or for plantmg. 

 Mixing the beans with an equal weight of 

 air-slaked lime will prevent damage. If to 

 be used for food only, the beans may be 

 heated in the oven to kill weevils, but if 

 the temperature approaches 150° F. the 

 vitality of the seeds is endangered.
