Fusarium, and an unusual development of chlamydospores was 
found (Fig. 11) after twenty days.

The chlamydospores were of typical size and took origin from 
any conidium. In fact, the fungus seemed to be passing into a 
resting stage for the hyphae also broke up into thick-walled 
portions and chlamydospores. 
CoNTROL MEASURES. 
A direct attack on the Fusarium or, indeed, on any soil- 
inhabiting and wilt-producing Fusarium, appears to hold out 
little hope of success, as witness the efforts made with regard 
to cotton wilt in U.S.A. There is, unfortunately, no progress 
_ to report from the experiments carried out in Uganda. It was 
mentioned in the carnation wilt paper cited that treatment 
consisting of a soaking with a solution of carbolic acid (one ounce 
to one gallon of water) at the rate of one gallon of solution to 
every four or five square feet was not successful in killing off the 
Fusarium, and it was indicated that the soil-fungicide Fungal 
which liberates formalin might be of greater avail. Van der Bij! 
in South Africa had no positive results when endeavouring to 
free soil of the same Fusarium, the cause of a carnation wilt, by 
the use of two-hundred gallons per acre of one per cent. formalin, 
but injections of formalin were proved to destroy the fungus 
of a carnation wilt disease, Fusarium dianthi, Pril. and Del., in 
France 
It was decided to experiment with Fungal and Izal. A drop 
of a five per cent. solution of the latter in a culture was found to
