INSECT PESTS AND DISEASES 59 



not really be accomplished by one spraying. For 

 that reason, let two applications be made at first, 

 within a few days. Afterwards, the frequency of 

 spraying may depend on the condition of the vege- 

 tables. Once in two or three weeks is often enough 

 while the plants look healthy. Wherever this 

 covers and as long as it remains, it prevents the 

 development of the spores of fungi. We must not

 is danger, in spite of the lime, of burning the 

 leaves. Keep in mind the natural hindrance to 

 growth from closed leaf pores. Nevertheless, its 

 continued application is indispensable. Bain may 

 wash off the spray. New growth keeps coming; 

 new shoots continually come into sight. We must 

 be ever on guard. At the appearance of a fresh 

 onslaught by our ambushed foes on new growth 

 or always after a rain, counter attacks by 

 the bordeaux should be made every few days to 

 guarantee safety. The best apparatus for this 

 work is a force sprayer. A garden sprinkler may 

 be used with fair success, however. During the

 without help from the gardener. Beetles and
