Exper. 9. Solulion conluining 0-13 % S.S. and 1 % sojl soap. 



1st day. Mildew greatly checked, with mycelium collapsed. 



3)rf (lai/. All the patches showing completely collapsed and flocculent mycelium, 

 quite sterile. 



Ilk day. All the patches apparently dying. 



lOlli day. As above. 



I5thday. All the patches with qiiilc sterile, oollapscd inyeeliuiii and evidently 

 dying. 



Exper. 10. Solulion conluining 0-13 % S.S. and 1 % soft soap. 

 Isl day. Mildew greatly checked, with mycelium collapsed. 

 8lh day. All the patches with collapsed, sterile mycelium. 

 Wthday. The mildew still white, but quite sterile and dying. 



Exper. 11. Solution containinfi ()-16 % S.S. and 1 % soft soap. 



l.sV day. Mildew greatly checked, with mycelium collapsed, short conidiophores 

 visible on a few patches; no injury apparent to the leaves. 



3rrf day. The short conidiophores still visible. 



llh day The patches of mildew dead (with collapsed and partially disintegrated 

 mj-celium) on the young leaves, which showed no injury from the spray; the two 

 older sprayed leaves curled up and turning brown, wliilc the control leaves remained 

 uninjured. 



10/7* day. The two young sprayed leaves now turning yellow and dying, and 

 falling at a touch. 



Exper. 12. Solution containing 0-16 % S.S. and 1 % soft soap. 



Isl day. Minute injury apparent at the tips of two of the leaves; patches 

 showing short, old conidiophores. 



3rd day. The old conidiophores still visible. 



8^/( day. AH the patches with collapsed, sterile mycelium ; the yovmg leaves 

 all seriously injiued at their tips. 



Wthday. The tips of all the sprayed leaves scorchccl and brown; large brown 

 dead area.s where the patches of mildew had been. 



Gooseberries. 1915. 



With tiie object of ascertaining the behaviour of the leaves to 

 ammonium sulphide before using the solution against American 

 Gooseberry-mildew the following three experiments were carried out. 

 Gooseberry bushes in pots in a greenhouse were used and the leaves, 

 fully-grown berries and tips of shoots were sprayed. Two varieties 

 of Gooseberry were used. 



Exper. 1. {Lancashire Lad.) Solulion containing 0-08% S.S. and 

 1 % soft soap. 



9lh day. Very slight injury ai)parent in the form of the yellowing and dropping 

 olT of a few leaves. 



1 1//( day. Xo further injujy. The whole of the injury caused was not appreciable 

 from the practical (commercial) standpoint.
