by L. J. Klotz, W. S. Stewart

Weed control: Effectiveness of soil treatment compared with contact sprays in rank growing crops
by A. S. Crafts
| Full text HTML  | PDF  
Not available – first paragraph follows: One of two contrasting methods might be used to control weeds in rank growing crops such as cotton, sugar cane, milo and corn: 1. A temporary sterilization of the soil to prevent the growth of weed seedlings and protect the crop; 2. A series of contact sprays beginning with a premergence treatment and following through with one or more post-emergence sprays until the crop is ready to lay by.

by H. S. Fawcett, E. C. Calavan
| Full text HTML  | PDF  
Not available – first paragraph follows: A defect or break in the bark is often the first outward symptom of wood pocket in a certain strain of semidense Lisbon lemon. A discoloration of the wood immediately inward from the break is found at the cambium.
