 Spray Calendar. 



COMPILED BY THE GOVERNMENT ENTOMOLOGIST AND 

 PUBLISHED BY THE BOARD OF HORTICULTURE. 



THE object of this Spray Calendar is to enable the fruit 

 grower to see at a glance what treatment should be given to 

 his trees to avoid or check injury from specific insects or 

 diseases. Only such insects and diseases are mentioned as 

 are known to be present and injurious in the Colony. It is 

 impossible to give technical information within the scope of 

 this calendar, but descriptions of all or nearly all of the 

 insects and diseases herein mentioned have been published 

 in the " Agricultural Journal," to which the reader is 

 referred. Information in regard to these, or to any par- 

 ticular insect or disease, with recommendations for treatment 

 to remedy or prevent the same, can be had of the Depart- 

 ment of Agriculture upon application to the Secretary, or 

 to the individual officers. 



Specimens of the insect or of the disease should accom- 

 pany the letter in all cases possible, and these specimens 

 should always be sent in a tight tin or wooden box. 



The time to apply the sprays is expressed by such 

 phrases as " When buds swell," since the actual date varies 

 greatly in different sections. No hard and fast rules can 

 be laid down as to how often the sprays should be used ; 

 but in general, adherence to the given directions will be 

 followed by success. Let the treatment in all cases be 

 prompt, thorough and persistent. If not effectual, communi- 

 cate with the Department of Agriculture, stating just what 

 has been done, under what conditions, and what results 

 were obtained. The officers of the Department will pro- 

 bably be able to explain your lack of success, and to advise 

 you how to proceed. 



For Red Spider on all plants, use Paraffine Emulsion as 

 for aphides persistently thoroughly drenching the lower 

 side of the leaves. Dry sulphur is also highly recommended. 

 On plants with hirsute leaves, such as the Cape Gooseberry, 

 Eed Spiders are very difficult to destroy, as the hairs 

 shelter them from the insecticide.
