176 Insects and Sprays 



Motor goggles should be worn when spraying 

 trees or high shrubbery to protect the eyes, other- 

 wise serious trouble may result. 



When the apple blossoms begin to fall, the fruit 

 grower should begin to spray. When the calyx 

 lobes close a couple of weeks later, the spraying 

 should stop. 



The little brown slug that eats the foliage of 

 cherry, plum, and pear trees in the summer time is 

 not difficult to control. It can be destroyed by 

 spraying with two ounces of hellebore in one gallon 

 of water. 



Pine-mice destroy fruit trees, attacking below the 

 surface, and their deadly work is not discovered 

 sometimes before the tree is dead. Bury a little 

 poisoned bran (mixed with Paris green) near tree 

 but not on the roots. 



When a greenhouse has been infested with insects, 

 all good plants should be taken out and the house 

 thoroughly disinfected. Burning 6 ounces of sul- 

 phur to every 1000 cubic feet of space and keeping 

 the house tightly closed for 24 hours will destroy 

 any insects. Any plants infected should be de- 

 stroyed, and this can be done by leaving them in 

 the greenhouse when the disinfecting is being done.
