PART IV. 5 on his return to South Africa, to ascertain what action the Union Government would be able to take and to inform the Agricultural Department of Kenya what measures would be possible. In this connection, Mr. Holm stated that he would write officially to the South African Department of Agriculture, informing them that this question had been brought up by the Conference and that he had asked Mr. Fuller to make further enquiries on his return. Mr. HOLM observed that even if special regulations were introduced to prevent the spread of Codling Moth to Kenya, there would seem to be a possibility, if similar regulations were not in force in Tanganyika, that the Codling Moth might be introduced via Tanganyika. He would like the opinion of the entomologists as to the possibility of the moth establishing itself in Tanganyika on native plants and then spreading to Kenya. It was generally thought by the Conference that such spread would be improbable but that it was impossible to be definite on this point until more information was available as to the host plants: so far, no instance of Codling Moth on native vegetation had been recorded. Mr. KIRKPATRICK expressed the view that the probability of developing an export trade in apples from Kenya should be the deciding factor in this discussion. If such export were probable, the risk of introduction of the pest was not justified and importation should be prohibited. If, on the other hand, it were improbable that an export trade would be established, it was not fair to the present generation to deprive them of such fruit. It was generally thought by the Conference that there were prospects of an apple industry being established in certain areas in Kenya; such being the case, every precaution should be taken to minimise the risk of the introduction of the Codling Moth. MEASURES SUGGESTED FOR THE PREVENTION AND SPREAD OF PLANT DISEASES. Mr. VAN DEN ABEELE said that, in order to prevent the spread of plant diseases, it appeared desirable that the transport of seed from one Colony to another, or even from one part of a Colony to another part, should be so regulated as to make examination and perhaps disinfection obligatory under the control of a competent service of the country of origin, whose certificate, valid for three months, should be attached to each invoice. He suggested that the Conference might discuss the methods of disinfection, and make suggestions for the different botanical species (cotton, maize, ete.) It was most important that all kinds of seeds should, on importation, be examined by the special service of the importing country, and that the results of investigation should be communicated to the country of origin, together with any enquiries which might be necessary. (Platyedra gossypiella was recently found on cotton seed imported from Egypt.) (The above was circulated as a note under T.C.(C)Ag.20.) Mr. FULLER thought that no efficient method of protection could be evolved by means of certificates from the exporting countries. From experience in South Africa he had no faith in any certificates 2),
