referred to are amongst the most destructive in Indi? 

 and will well repay study. The experiments at Poona 

 farm to raise a resistant strain of pigeon-pea, have been 

 in progress four years and are promising well. 



10. jhdherry Disease of Kashmir. — In a visit to 

 Kashmir during the months of July, August and Septem- 

 ber, 1908, the Imperial Mycologist enquired into the 

 diseases of mulberry and also those of apple, pear, peach, 

 quince, cherry, apricot and grapevine. The results of 

 part of this work have been published, and recommenda- 

 tions made for dealing with mulberry diseases. The 

 study of the other diseases is in progress. A large col- 

 lection of fungi was also made for the herbarium and these 

 are being gradually worked out in the laboratory. 



11. Ginger Disease. — This disease causing consider- 

 able damage in Eastern Bengal was investigated, and the 

 probable cause of the disease determined. Experiments 

 are still being carried out with the disease. 



12. Other Diseases of Plants. — A new anthracnose of 

 val (Dolichos lablab), some species of the rare genus, 

 Choanephora, and the two maize smuts of India, have been 

 studied, and a successful attempt has been made, to work 

 out the life-history of the very obscure paddy smut. As 

 usual a large number of other diseases of crops were 

 examined, and this work has formed a large portion of 

 the routine work of the staff.

 Entomologist an attempt was made to ascertain the cause 

 of the heavy mortality amongst eri-silkwovms during the 

 hot weather of 1908 at Pusa. The mortality appears to 

 be due to a specific disease allied to, but not identical with, 

 that known as " flacherie " in ordinary silkworm, 



14. Programme for 1909-10. — It is proposed to continue 

 the work with sugarcane diseases and to publish a further 

 contribution to our knowledge of red rot. If sanctioned 

 by the Government of Madras, the palm disease campaign 

 in the Godaveri delta will be continued. An account of
