VI Crop Diseases and Insect Pests. 



7. Red bugs on cotton, sagarborer on Jowar, catterpillar on 



Sau, bugs and leaf-eating beetles on almost all the crops were 

 among the insect pests. The damage from these was not of 

 a serious nature. The red cotton bugs were collected and 

 destroyed. The other pests were checked by hand-picking where 

 possible. 



Smut appeared on both Bajri and Jowar. The smutted heads 

 of Bajri were sent to the Imperial Mycologist for examination. He 

 writes thus: "This is the first occasion I have seen such a disease 

 on this cereal and the fungus is probably a new species. 53 



The wheats were attacked by rust the common Puccinia 

 Grammonis, and the gram by wilt caused by a species of 

 Fusarium, 



8. Tikka disease of groundnut. In all five varieties of 

 groundnuts were grown on the plot devoted to the study of this

 germination of all was fair. The disease first made its appearance 

 on the 23rd of July 1906 on three varieties, mz. t Spanish peanuts, 

 small Japanese and Virginia and gradually spread to all the rest. 



The diagrammatic statements overleaf show the relative
