growing parts of the world, it does not appear to be prevalent 

 in India. Possibly this may have some connection with the 

 following statements : — 



On page 75 of the Annual Report of the Imperial Department 

 of Agriculture in India for 1904 and 5, in a paragraph dealing 

 with fungus pests, is written : " Spraying, which is in its infancy 

 even amongst the more highly educated farmers of Europe, is 

 not likely to be generally adopted by the ryots for some time to 

 come, and, indeed, the number of diseases that I have seen in 

 India which are likely to repay spraying is small. No special 

 attempts have been made, therefore, to introduce spraying into 

 practice." 



In the same volume, p. 91, the following statement occurs: 

 *' Every opportunity has been tal^en of testing remedies which 

 are of use in other parts of the world. This investigation is 

 only possible Avhere injurious insects are met with in sufficient 

 number, and cannot be carried on continuously. The conditions 

 under which agriculture is practised in India differ so much 

 from those of countries where these remedies are discovered, so 

 that any attempt to introduce European and American methods 

 must be preceded by exhaustive trial." 



From the above it seems probable that up to the end of the 

 year 1905 at least, spraying was not practised to any extent in 

 India. In none of these reports can I find any reference to the 

 presence of codlin moth, and I have unfortunately been unable 

 to obtain 'a copy of Mr. Miaxwell-Lefroy's Indian Insect Pests, so 

 that I am not able to say to what extent the codlin moth occurs 

 in India. 



Mr. Pescotti Avrites : " It is stated that where the codlin moth 

 has obtained a foothold in India it is impossible, owing to 

 climatic influences, to use arsenate of lead, as it burns the trees 

 severely, so chromate of lead is used in its place, reputedly with 

 good results." 



This spray was used at Burnley over a limited area of the 

 orchard, but Mr. Pescott says wherever it is sprayed it leaves 

 yellow blotches and spots, otherwise its success as an insecticide 

 is absent.
