An account of the disease caused by this fungus; suitable remedies 

 are suggested with a view to prevention. The disease has only been 

 known in Australia a few years. A. D. Cotton.

 (Isaria farinosa [Dichs.] Fr.) (Journal of the Department of 

 Agriculture of Victoria. Vol. II. Jan. 1904. p. 468-471.) 



Describes the attack of the Codlin Moth grub by a parasitic fungus, 

 which in some parts of Victoria has assumed almost the nature ot an 

 epidemic. The fungus agrees very closely with Isaria farinosa (Dicks.) Fr. 



The author discusses the possibility of the use of the fungus as an 

 insecticide, and concludes, that it is only in certain seasons and in cer- 

 tain localities, that the fungus is produced in sufficient abundance to 

 effect noteworthy results, and that it could only be used at present as 

 an addition to, and not a Substitute for, other means which have proved 

 themselves effectual. A. D. Cotton. 



Mc Alpine, D., „Take-all" and „White-Heads" inWheat. 

 (The Journal of the Department of Agriculture of Victoria. 

 Vol. II. Jan. 1904. p. 410—426.) 



The diseases of wheat popularly known as „Take-all u and „White- 

 heads" in Australia, are shown to be one and the same disease, and 

 caused by the fungus Ophiobolus graminis Sacc. 



The fungus exists in the soil and attacks the roots of the wheat 

 plant, causing it to die in its early stages (Take-all), or after producing 

 its ears usually without the development of grain. (White-heads). 



The remedy most strongly recommended is a proper rotation of 

 crops, since the fungus may be starved out by depriving it for a time 

 of its normal food, the wheat plant. Oats grow well in „Take-all" patches 

 and are not attacked by the fungus. 



Numerous photo-micrographs are given and a map showing the 

 distribution of the fungus in Victoria. A. D. Cotton.
