indigenous to the country or locality; besides these, there is always
the possibility of pests belonging to other parts of the globe being
introduced. It is of great importance that the Agricultural
Departments of these different countries should be notified of any
such outbreaks, not only for administrative purposes, so that
regulations to prevent the spread of such outbreaks can be enforced,
but for the information of their entomologists and mycologists, whose
work might be greatly assisted by any available information regarding
the pests’ life histories, how the disease may be spread, meteorological
and ecological conditions which favour their spread and what chances
there are for such spread.
Unauthorised reports of outbreaks may cause unnecessary alarm
in adjoining territories, but if the Agricultural Department concerned
were to issue a full report on this, which could be circulated to other
countries, it might help all concerned. For example, last year the
Government entomologist of a certain colony discovered the pink
bollworm in an isolated district: it also occurred in the adjoining
district of a neighbouring colony. From information collected by
him, it was probable that this pest occurred north of that area on the
native indigenous kidney cotton. It was only by chance that the
Government entomologist was called to go up to this district to
examine native cotton crops, when he discovered the infection. If
it is true that the pest does occur to the north of this tract and that
there was a danger of infection, then such information, if it had been
furnished by one Government to the other, would have been of the
greatest importance both from an administrative and entomological
point of view. From an administrative point of view because the
District Administrative officer had been doing his best to foster cotton
cultivation in his district and with considerable success, when
suddenly he had to tell the people that they were not allowed to
grow cotton any longer: also from the point of view of movements of
cotton from this area. If a full statement of the outbreak had been
issued and circulated to other countries, stating what steps had been
taken to prevent the possible spread of this pest elsewhere, where the
area was situated, what were its boundaries and what possibility
there was of its spreading by cultivation, it might quite well have
allayed any alarm created by any unauthorised reports which may
have been circulated.
Such reports also, following on such a Conference as this, where
scientific officers concerned with ‘cotton diseases have a chance to
meet and confer, will undoubtedly lead to closer co-operation and
collaboration in the future, esvecially if information concerning such
pests is circulated as suggested in this note.
(8) SEED IMPROVEMENT: METHOD OF TESTING NEW AND
IMPROVED STRAINS OF COTTON IN DIFFERENT PARTS
OF THE COUNTRY.
(Note by Mr. H. C. Sampson of the British Empire Cotton Growing
Corporation.—T.C.(C)Cot.4.)
It is taken for granted that, when new and improved strains of
cotton have been produced on a central station, they will have to be
tested to find out how far they are suitable for different parts of the
country.
