The lower leaves were first affected and the mildew gradually spread upwards. 

 Affected leaves were covered with a dense white mycelium and conidia were 

 abstricted profusely. 



Tomato ( Lycopcrsicum esc}ilentiim Mill). 



The chief tomato disease was "mosaic" indicating in all probability that the 

 variety propagated was running out. This view was supported by the reduced 

 yield as compared with previous crops. 



Leaf Mold caused by Cladosporiuni fulviim Ckc. was also prevalent especial- 

 ly towards the latter end of the season. 



Violet {Voila odorata). 



Leaf spot caused by Altcrnaria vlolac G . and D. was very destructive, the 

 leaves being in most cases killed. The spread of the disease was checked by the 

 use of Bordeaux but spraying the plants with Bordeaux spoils the foliage for 

 commercial purposes. Careful attention at watering time is essential in the green- 

 hause. 



ECONOMY IN SPRAYING 

 Rev. Father Leopold, Oka Agrlc. Institute. 



Spraying is one of the most important i:)ractices in fruit-growing ; in fact, 

 I believe that it is the most important. You may not care to go to the trouble 

 •of cultivating the soil of the orchard, to put in a cover crop, even to prune, but 

 if you wish to market first class fruit, you must spray. 



With every item in orchard practice to-day costing much more than a few 

 years ago, it is up to the fruit-grower to practise the strictest economy in all his 

 operations, but especially is this so of spraying with ECONOMY IN SPRAY- 

 ING. 



Economy. — What I mean by economy, you readily understand, is not to 

 spare anything when the time of spraying has arrived or not to put on each 

 tree the quantity and the quality of either dust or li(|uid applications. 



\. — Economy procured by thorough pruning. It is evident that in an orchard 

 which is not regularly pruned and well pruned there is a great loss of time and 

 material in applying unduly liquid or dust sprays to ])arts of trees which should 

 have been eliminated prior to the spraying of each tree. But that is not the main 

 point. 



Both insects and fungi harbor on the litter and rubbish distributed on parts 

 of the tree which should have been previously removed by thorough pruning. 

 Preventing the spores of diseases from germinating and the eggs of insects from 

 hatching are so much done in the prevention of pests that may require consider- 

 able spraying to overcome. We overlook this i)oint too frequently 



Insects and fungi harbor also on the litter and rubbish distributed on the 

 ground and particularly in the accumulation of growth and litter along fence rows
