40 JoruisAL OF THE IJEPAUXMEiS'T OF Agricultuee. JuLY, 1922. 



(1 :45 or 1 :50) is as effective as bordeaux, but causes a little burning 

 of the foliage, altliou<j:h not sufiicient to affect the fruit crop. (4) 

 The vseasons 1920-21 and 1921-22 have shown very markedly that 

 the times of application of the sprays for the control of disease 

 should vary with the seasons, and meteorolofjical data, especially in 

 lespect to temperatiires and rainfall, M'ould greatly assist in the 

 economy of carryino- out the spraying operations. 



It is quite possible that the two sorays before blossoming were? 

 unnecessary for the 1921-22 season at Elsenburg. Worse infestation 

 of fusicladivim appeared during this season after the fruit was 

 removed. A similar occurrence happened in the Paarl district with 

 regard to the control of nidiuvi. The worst infestations appeared 

 on the foliage after the crop had been picked. 



It would, therefore, seem that our present recognized times of 

 applying treatment may be at fault in so far as fusicladium is 

 concerned, and that with more definite knowledge of weather condi- 

 tions at certain times during the season, it may be to the best 

 advantage to omit one or two sprayings, or with adverse weather 

 conditions, it may be wise to apply an additional spraying. 



No literature apjiears to have been published on this aspect of 

 spraying, and in conjunction with the entomologist, meteorological 

 records are now being noted from month to month. 



Citrus Export : New Regulations. 



The Trade Commmissioner states that in view of the numerous 

 complaints made during the last citrus season in regard to the 

 grading of oranges, he circulated among those concerned in the 

 trade in London copies of the new regulations, which were published 

 in the May, 1922, issue of the Journal, and that, as far as he can 

 ascertain, these regulations meet with general approval, the trade 

 being of opinion that if they are strictlj^ enforced the confidence of 

 buyers will be increased and the trade generally benefited by the 

 higher standard of quality of fruit that may be expected to I'esull 

 therefrom .
