HC Deb 01 August 1912 vol 41 c2282W

asked the President of the Board of Agriculture whether his expert advisers share the view expressed by some scientific experimentalists that a heavy dressing with kainit or other potassic manure in the first week of January of land about to be sown with oats is a certain preventative of stem eelworm and frit-fly in that crop; and, if so, whether he will publish advice to farmers to this effect so as to avoid the recurrence of the present widespread oat sickness?


Dressings of potash salts have been shown to be beneficial in cases of attack by stem-eelworm, and are already recommended in the Board's leaflet on this pest. But the Board are not aware of any scientific evidence indicating that kainit or other potash manures act as a preventive of frit-fly.
