Milk is a good fungicide
I got this note from my friend in Swaziland. Thot I'd sent it along. Ruthie
>I must say I was shocked to read that syraying ordinary cows milk mixed with
>water in a 1:9 dilution is as effective at preventing the growth of the
>powderey mildew mould /Sphaerotheca fuliginea/ on cucumbers and zuccini as
>any commercial chemical fungicides!
>This was a discovery by Wagner Bettoil in Embrapa, the Brazilian
>Agricultural Research Corp. He sprayed it on heavily affected plants twice
>a week. It worked as well as Fenarimol or Benomyl. In many cases milk was
>faster and more effective. In some cases it was 6 times more effective as a
>fungicide. It qualifies as an organic treatment.
>Effective control can be maintained with a 5% spray once a week. It is not
>yet clear why it works but it might boost the plant's immune system.
>Powdery mildew is a serious problem in Swaziland where we cannot grow
>certain crops in some areas because of its endemic presence.
