My animals were most carefullyselected for the work
they had to do and for the local climate. This eelworm story is being continued in
Rhodesia. FOOT-AND-MOUTH DISEASEIf this holds for plants, why should it not apply to
animals?
John Tarves at Heversham in SouthWestmorland. The
veterinary surgeon reports that it is the best T. I secured samples of the roots
ofthese thriving strawberry plants and asked Dr.
The difference is most pronounced in those years
when clover seed isgenerally a poor crop.
Foot-and-mouth is considered to be a virus
disease.
This was one of the best examples of the retreat of
virusbefore soil fertility I have so far seen.
The control plot alongside was a red carpet of this
pest. The rootsystem of these three sets of types was then explored. Has the potato
in thecourse of years lost something, or was its original introductionimperfect?
Three further questions suggest themselves. The same results were invariably
obtained.
Its use, as was to be expected,was not usually
beneficial on virgin soil. The crops were excellent and no soiltroubles or pests
were to be seen.
It may well bethat the efficiency of this
association is one of the chief factors inseed formation.
But all my efforts to get this done failed
toovercome the inertia of departmentalism.
The veterinary surgeon reports that it is the best
T.
After two or three years the potatoes of one crop
cannotbe used to raise the next.
Theplots were arranged side by side on land well
manured with compost. Everything will then be readyfor a simple experiment in
disease prevention.
The difference is most pronounced in those years
when clover seed isgenerally a poor crop.
The coat of the working animal mustalso be kept
clean and free from dung.
Is the mycorrhizalassociation, which is known to
occur in sugar-cane, involved in thismatter? Has the potato in thecourse of years
lost something, or was its original introductionimperfect?
This is collected by theislanders and used for
their potato patches. All thisconsolidated the moist silage and allowed the proper
fermentation tobegin. Such attempts to control anoutbreak should cease. The twigs
and leaves are nowhealthy and quite free from pests.
In due course answers to thesequestions will no
doubt be provided.
Ifthese soils begin to respond to artificials,
attention should be paid tothe humus supply.
