Insecticides. 



Award of Merit. 



" Katakilla " Powder Insecticide Wash, from Messrs. McDoiigall; 

 Port Street, Manchester. This preparation was tried on fruit 

 trees of different kinds and on roses, especially for aphis attack. 

 It gave excellent results, in most cases completely clearing the 

 trees of the pest. It was also tried on black fly of bean with like 

 results. No damage whatever was done to foliage. The preparation 

 is easy to mix and apply by any ordinary spraying machine. 



Highly Commended. 

 " Carlton " Arsenate of Lead, from Messrs. Voss, Glengall Road, 

 Millwall, E. This preparation was used against the caterpillars 

 of winter moth, &c., on fruit trees. It was easily mixed and applied, 

 and proved deadly to the caterpillars. 



Soluble Green Fly Insecticide, from Mr. Henry Morris, Baltic 

 Works, Newport, Mon. The preparation was tried against aphis 

 in the greenhouse, on Cinerarias, Pelargoniums, and potatos. The 

 aphis was killed without damage to the plants. It was also used 

 outdoors on roses with the same beneficial result.

 edge, and in one form, with several small perforations.

 diameter.
