NOTES ON SOME INJURIOUS FUNGI. 93 



under side of the leaf in the centre of the white spots. They are cylin- 

 drical and supported on stalks about twice the length of the spore. 

 This disease is increasing all over the country and is now recognized 

 as one of the worst pests of the strawberry. Lime dusted on the leaves 

 is one of the best known remedies. It should be applied every two or 

 three weeks, beginning in April, and continue until the fruit sets. The 

 disease rarely attacks healthy plants ; keep i)lants in a healthy condi- 

 tion by good cultivation, and by giving them a sufficient quantity of 

 plant food, and you will experience little trouble with the fungus. 



DISEASES OF THE GRAPE. 



Many of you are doubtless aware that two kinds of mildew occur 

 on the foliage of the grape ; both species of which were fully described 

 at the last winter meeting. The first. 



Peronospora vitieola (American grape mildew) joins certain definite 

 spots on the under side of the leaf. In the centre of the spots may be 

 seen little mealy tufts; these are the reproductive bodies, the plant 

 body or mycelium is internal. 



The second. Uncinula spiralis (European mildew) occurs on the 

 upper surface of the leaf, and the plant body is superficial. This 

 fungus causes no great amount of damage* in this county: it is the first 

 mentioned species {Peronospora) that is the most destructive. 



Sulphur and copperas have been used with success, but the fol- 

 lowing mixtures is highly recommended by M. A. Millardet of Bor- 

 deaux, France. We would advise you to try the remedies and report 

 at the next winter meeting. The following is Millardet formula: 



In twenty-six and one-half gallons of water desolve seventeen and 

 one-half pounds sulphate of copper, also make with eight gallons of 

 water and thirty-three pounds of lime a thick lime milk, and mix with 

 the solution of sulphate of copper. It will form a bluish paste. Some 

 of this is poured into a bucket (thoroughly stirring it) and is applied 

 to the leaves with a broom or brush taking care not to touch the 

 grapes. 



Another remedy is simplj- a lime wash made as follows ; Lime, five 

 and one-half pounds; water, twenty-six and one-half gallons. Sprinkle 

 the foliage with the wash every two or three weeks, beginning in May. 

 A single application of the first mixture made about the time the Per- 

 onospera appears (1st of July) is sufficient. 



Hoping the suggestions offered will be of some value to you, I 

 remain, EespectfuUy,
