6. Insure an early crop by early planting of early-maturing 

 varieties, and by fertilizing where necessary. 



7. Continue the procuring of an early crop by early chopping 

 to a stand and early and frequent cultivation. Do not lose the fruit 

 the plants have set by cultivation too deep or too close to the rows. 



8. Where the labor is sufficient, pick the first appearing weevils 

 and the first infested squares. Do not destroy the squares, but 

 place them in screened cages. By this means the escape of the 

 weevils will be prevented, while the parasites will be able to escape 

 to continue their assistance on the side of the farmer. 



9. Use a crossbar of iron or wood, or some similar device, to 

 cause the infested squares to fall early to the ground, so that they 

 will be exposed to the important effects of heat and parasites. 



10. Do not poison for the leaf-worm unless its work begins 

 at an abnormally early date in the summer.
