REMEDY NO. 47. 



The greatest care should be taken in procuring nursery stock

 be dipped in No. 11 or 12 — one pound of the mixture to each 

 one gallon of water used ; or No. 13 — one pound to each 1^ 

 gallons of Avater used, excepting the roots, which should be 

 dipped in No. 5 or 7 — one pound to each one gallon of water

REMEDY NO. 48. 



To prevent the spread of the black scale, soft orange scale, 

 red scale, cottony cushion scale, etc., on citrus trees, the branches 

 should be thinned out, to give free access to light and air, and 

 also to give an opportunity for thoroughly spraying. All 

 prunings taken from the infested trees should be immediately 

 burned. 



REMEDY NO. 49. 



The best season for destroying scale insects on citrus and 

 evergreen trees is when the young larvae are just hatched, and 

 are creeping over, the fruit, foliage, etc. Then apply No. 5 or 

 7, four pounds of the mixture to every five gallons of water 

 used, excepting for red scale, when one pound of the mixture 

 to each gallon of water used Avill be more effective. The sul- 

 phur is necessary for destroying the black smut or fungus. 

 The application should be repeated when the second brood of 

 larva? appears. Effective results have been obtained by using 

 No. 4. Care should be taken not to spray the trees in very 

 warm weather, or in the heat of the day, as it may cause some 

 of the foliage and fruit to fall off. But to get rid of the pests 

 some inconvenience must be expected. A])i)ly the above solu- 

 tions at a temperature of 130° Fahr.
