are, however, required before deciding on lime sulphur as 

 the routine treatment. 



For the Coniothyrium disease the same sprays were used. 

 In general the superiority of the fruit on the sprayed rows 

 was very marked. The home-made lime sulphur and 

 Berger's mixture both gave good results and did no damage 

 to the trees. Burgundy, however, caused so much damage 

 to fruit and leaves as to be largely a failure. This bears 

 out recent work in English orchards with this mixture. 



There was little Leptothyrium present but the trees 

 sprayed with lime sulphur and Burgundy had certainly 

 less than the others. Burgundy injury was again marked. 

 Peach leaf curl was entirely controlled by all three sprays. 



The variation between different varieties in suscepti- 

 bility to disease as well as in resistance to Burgundy injury 

 is so marked that it is useless to expect comparative results 

 unless the tests are made on the one variety. Northern Spy 

 is so susceptible to mildew that it is being discarded on at 

 least one estate. -King of the Pippin was immune to 

 Coniothecium. Burgundy injury was very bad on Cox 

 Orange Pippin and the leaves were scorched on Esopus 

 Spitz, while King of the Pippin was quite free from it. 



I visited Ramgarh in October with Dr. Shaw and dis- 

 cussed future work on the spot. The proprietors of the 

 Allen Orchard are kindly placing at our disposal a small 

 building for mycological work. Owing to Dr. Shaw's 

 absence no new experiments have been carried out in the 

 1920 season. 



(3) Cereal diseases. It has long been apparent to 

 mycologists in India that there is a large group of parasites 

 belonging to Fusarium, Helminthosforium and allied 

 genera which attack cereals throughout the country. Some 

 of these, such as the stripe disease of barley, are well known 

 in other countries, others appear to be peculiar to India or 

 at least have not been previously described. Mr. M. Mitra 

 took up the study of the species allied to 11 elminthosporium 

 and has made considerable progress in this enquiry, which 

 is likely to extend over several years.
