intended for use for protecting the grape vine, the hop plant, or like plants, or
cereal, or root, crops from parasites, insects, or fungus, but can also be used for

alkali waste and oxidise it to such an extent that the sulphides are converted into
sulphites. I then finely divide, or grind, the material thus prepared, and it is then
ready for use, as a powder, for distributing over the plants, or with the seed. If
it be desired to apply the preparation, or material, in a liquid form, I may mix it
with water, or other liquid, preferably agitating it whilst applying it, and in
this case I may use the unoxidised alkali waste.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that
what I claim is: ---
1. For protecting plants, or vegetable life, from parasites, or injurious germs,
