Dusting and spraying- trials in the orchard to determine (1) the 

 effect of Bordeaux liquid on lead arsenate when the two are used in 

 conjunction in the control of codling moth; (2) the relative efficiency 

 of lead arsenate paste, lead arsenate powder, calcium arsenate paste, 

 calcium arsenate powder, and arsenate of soda in the control of 

 codling moth ; the practicability of dusting in place of spraying in the 

 control of codling moth and fusicladium.

Fruit and Vegetables : A Great Manufacturing Scheme. 



Representatives of certain well-know^n British manufacturers have 

 recently been touring the Union with a view to establishing a number 

 of factories for jam-making and vegetable canning, commodities for 

 which their firms are world-famous. Fully conversant with both the 

 business and technical aspects concerning' the numerous preserved food 

 products dealt with, these representatives have visited a large number 

 of centres, keeping in view the possibilities, present and future, of 

 starting similar manufactures in the Union. Their first aim is to 

 select centres, promising sufficient produce, labour, etc., to warrant 

 the establishment of, say, four factories, mostly on the coast or at 

 any rate in a big town,. each factory to be on not less than a twenty 

 acre stand so as to provide ample room for expansion. The chief 

 products required are apricots, plums, peaches, apples, pine- 

 apples, Seville oranges, vegetables (such as beans, tomatoes, etc.), 

 and, in a lesser degree, tropical and sub-tropical fruits, such as 

 mangoes and pawpaws. 



When it is mentioned that such huge quantities as 10,000 tons 

 each of apricots, plums, and Seville oranges — quantities far beyond 

 the present capacity of the Union — could be dealt with by the pro- 

 jected factories, as a start, and that several millions of money will 

 be forthcoming for investment in these operations, the magnitude of 

 the scheme and its importance to the Union will be realized. Indeed, 

 the firms concerned, it is understood, are prepared to face considerable 

 initial financial loss, provided supplies of raw materials are in sight 

 ensuring an annual expansion of the trade. Naturally the impetus to 

 fruit-growing would be great. It is understood that the scheme 

 provides for assisting growers to establish and maintain large areas 

 of fruit, etc., provided that portion of their produce is supplied to the 

 factories for a number of years, either at a contract price or 

 prevailing market rates. 



What the outcome of the visit will be is not yet known. That 

 the required annual supply of fruit, etc., cannot be met in full for 

 some years to come is certain, but we believe that as a result of their 

 tour, the representatives are favourably impressed with the outlook 

 and the possibilities of development for fruit-growing- in South Africa.
