Winter Washing of Fruit Trees. The Journal of the Board 



of Agriculture, Vol. XVI, N. 10, p. 832. London, January 1910. 

 . 



" A neglected orchard not only harbours during the winter all 

 manner of insect enemies which commence their ravages in spring, 

 but forms a nursery or breeding-ground from which other orchards 

 are infested with noxious insects. The first step, therefore, is to 

 destroy these pests as far as possible, and for this purpose winter 

 washing is practised." 



Some formulae for winter washes are given. 



Protection of Timber against White Ants. -- Abs: Nature, 

 vol. 84, n. 2133, September 15, 1910, p. 342. London. 



A Note on the protection of timber against white ants appears 

 in the Transactions of the Royal Scottish Arboricultural Society 

 (vol. XXIII, part II). Three processes are described, of which one 

 is a contrivance for destroying white ants by pumping a poisonous 

 smoke through their galleries, while the others are timber-treatment 

 measures. Details of the Powel process are not disclosed, but 

 blue oil is the specific which apparently has received recognition 

 at the War Office. 



Report by T. H. Middleton on Destructive Insects and Pests, 

 in application of the Destructive Insects and Pests Acts, 

 during 1908. The Journal of the Board of Agriculture, vol. XVI, 

 No. 10, London, January 1910, p. 845, Cd. 4934. 



One of the early steps taken under this Act was the passing 

 of an Order designed to some extent to protect the country against 

 the introduction of new pests by requiring the occupier of any 

 premises on which certain pests are discovered to report the fact 

 to the Board. The pests selected include five insects and four 

 fungi, which are among the most serious enemies of plants abroad. 

 Of these, the Vine Louse or Phylloxera, the San Jose Scale, the 

 Mediterranean Fruit Fly, the Colorado Beetle, Black Knot, and 

 White Root Rot are not known to exist in this country, though 

 some of them do occur occasionally. On the other hand, the 

 Large Larch Sawfly, Black Scab of Potatoes, and American Goose- 

 berry Mildew are, unfortunatly, prevalent. Each of these pests 

 is dealt with in the Report, and the action taken in regard to 

 them is described.
