NOTES ON SOME OF THE INSECTS AND FUNGOUS 

 DISEASES AFFECTING HORTICUETURAE 



CROPS. 



Only the insects and fungous diseases enumerated by 

 the Board of Horticulture, as very dangerous pests, are 

 here described, and while they do not represent all those 

 that injure our horticultural crops, yet, they do repre- 

 sent the more dangerous ones. 



The good old adage ''an ounce of prevention is worth 

 a pound of cure" must be our motto, for, in fact, it is 

 the foundation on which our Horticultural Law is built, 

 i. c, to examine all nursery stock so as to keep out the 

 various insects and fungous pests. 



Unfortunately the San Jose scale is found in many 

 parts of Alabama. It was brought here on nursery stock 

 from infested localities, and there is no hope of entirely 

 ridding our state of this scale, but with the earnest ef- 

 forts of the various growers, we should be able to keep 

 it from spreading farther. 



The State Horticulturist is ready to do all he can, to 

 help in preventing the spread of the various pests on 

 nursery stock, and to aid the owners of infested orch- 

 ards to rid their premises of them. 



Recommendations. — The best, as well as the most 

 practical way of treating nursery stock, is to fumigate 

 it with hydrocyanic acid gas. This is usually done by 

 the nurseryman before the stock is packed for shipment. 

 It should not be considered as an entirely safe remedy, 

 but, rather, as one of the safeguards to use in securing 

 clean stock. All growers should be continually on the 

 watch for the first indication of any trouble foreign to 

 the natural growth or habit of plant or tree. 



After the trees have been pruned and ready to be 

 planted, they may be dipped in the lime, sulphur and 

 salt solution for a moment. This covers the trunk and 

 branches with this insecticide, and should destroy most 

 of the living scales. 



Caution — In doing this only dip the top, do not submerge the 

 roots, and do not treat at all when the buds have started. Fumi- 

 gation or dipping can only be done when the trees are dormant — 

 never after growth has started.
