DISEASE OP CHILLIES. 



VERY closely related to and perhaps identical with the black rot of 

 the tomato is the present rot of the Chilli. The fungus, whose spores 



are shown in Fig. 96, occurs on the 

 fruit, often in its eye. In this 

 respect as well as in the form of the 

 spores it resembles the similar rot 

 of the tomato. 



I have met this disease but once, 

 and have no experience as to the 

 effect of fungicides on it, nor do I 

 recollect any writings on the sub- 

 ject of diseases of the Chilli. The 

 best suggestion seems to be that remedies found useful for the black 

 rot of the tomato may be expected to act favourably on this very 

 similar disease of the Chilli. 



ONION DISEASE.' 



THE following appearances were noted on some imported onions, and 



gave rise to inquiry 

 as to whether there 

 was any danger to the 

 crops of the State from 

 the importation of 

 such bulbs. 



Most of the bulbs 

 composing the ship- 

 ment were perfectly 

 sound. Yellowish 

 holes through the 

 outer scales appeared 

 on some of the speci- 

 mens. These holes 

 were six to ten milli- 

 metres across. The 

 sunken and diseased 

 tissue contained a strong growth of colourless mycelium, in the midst 

 of which dark, spherical, smooth or warty spores were found which 

 measured 4-5 micromillimetres in diameter. There was no positive 

 evidence that the spores were connected with the mycelium beyond 

 that of juxtaposition. The examination was conducted for the 

 guidance of inspectors under the vegetation diseases act. The 

 evidence was not considered of sufficient definiteness and importance 

 to warrant any definite action. 



ANTHRACNOSE OF THE PIG. 



With us the foliage of the fig does not suffer much from fungus 

 disease ; but there is an anthracnose not uncommon, which sometimes 

 does considerable damage. The appearances produced by this disease 

 are shown in the plate opposite. As a result of the disease, the fruit
