1.PRES. 1      Good evening listener! It is another time we are happy to wel-come you to listen
              to your programme “CONTROL IRISH POTATO FUNGUS FOR MORE
              PROFITS”! Your hosts in the studio are Lilian Isindu and.......

 2.PRES 2     Jared Mukarebe! Very pleased to bring you to-day’s programme .A programme
              that will focus mainly on the deadly disease of Irish potatoes “Late potato blight

 3. PRES 1    In to-day’s programme we shall focus on how the disease affects the plant, how
              you can identify the disease on your crops and how afarmer can manage the
              disease. On top of that we shall read and answer listener’s letters and our
              competition will not be left behind.

 4. PRES 2    For along time, Irish potatoes have been grown in our country. They are ranked
              number two in terms of important food crops.

 5. PRES 1    In our country, Irish potatoes are grown in plenty in Central province, Riftvalley
              province and in Eastern provinces.

 6. PRES 2    Besides being an important food crop, many Kenyans derive their livelihoods
              from growing the crop.

 7.PRES 1     However, late Potato blight is abig threat to irrish potato production in our

 8. PRES 2    But the good news to our farmers is that our scientists are spending the better part
              of their time, looking for solutions to fight the blight.(threat)

 9. PRES 1    We set out to findout what the scientists are doing to combat the disease.We
              talked to a number of research scientists.

 10. PRES 2   First we talked to Dr. Betty Gondwe! And from her we wanted to find out what
              they have done so far in terms of research that is useful for the farmers.


             A lot of research work has been carried out. One of the m has been to find
             resistant varieties to this disease, we have also carried out research to find
             out the sources of the disease for example how seed from infected potato ca n
             be asource. We have also conducted various researches with various
             fungicides to acertain how they can effectively be used by farme rs to manage
             the disease in their farms.We have given recommendations which farme rs
             can use in their areas .

11. PRES 1   Dr, Betty Gondwe with on going research!

12. PRES 2   But if the farmer will be able to follow recommendations and be able to manage
             the disease, then they must be able to identify the disease! Here Dr, Gondwe
             explains how the farmer can identify the disease on his/her crops.

          Late potato blight disease which is caused by a fungus can be seen on the
          leaves,stems and even on the tube rs.On the leaves it starts with brown spots .
          If you inspect the leave closely on the underside especially in the morning,it
          will have a white mass and on the branches the fungus causes breaking of
          branches, the fungus also affects the tube rs.

13. PRES 1   But if the farmer started with clean certified seed, where does the disease come
             from? This question we asked Ms Grace Ngatia.

          This disease can come in from neibouring farms. May be there is afellow
          potato farme r who did not plant resistant varieties and the disease is already
          on his farm, the disease can spread from there to your farm. The disease can
          also come from other crops and weeds of the same family with potatoes like
          tomatoes.The disease can also come from volunteer potatoes which we re left
          in the farm and already are infected.

14. PRES 2   This disease can spread from neibouring farms to other farms. But what is the
             cause of the disease?

          Many farme rs have mistakenly believed that the disease is caused by cold or
          frost to an extent of nicknaming the disease”the disease of frost” I would like
          to correct this and tell the m that the disease is caused by a fungus and when

              we have a lot of humidity brought about by lot of rain is when the disease
              spreads quickly and the effect is seen on crops. This is why many farme rs
              believe that it is this condition that causes the disease but the truth is that this
              weather conditions are only conducive for the growth of the fungus which
              causes the disease.

15. PRES 1    Ok! So it is not cold! The cause is afungus!

16. PRES 2    It is not only you Lilian! Even me I thought it was caused by a lot of rain. Now
              we have been told! Let us listen to some music as we think about the fungus that
              causes late blight. When we come back we will hear how farmers can manage the

                             INSERT MUSIC

17. PRES 1    Jared I hope by now the music has relaxed you and you are now ready to continue
              with the programme isn’t it?

18 PRES 2     absolutely Lilian let’s continue!

19 PRES 1     Then let’s join Mercy Wahiu explaining how afarmer can manage the disease..

          Acording to the research we have carried out concerning this disease, we
          recommend that farmers should combine use of resistant varieties together
          with use of fungicides. Among the resistant varieties we have are Asante and
          Tigoni which can be found from Tigoni Kari research station.For good
          results, these varieties should be sprayed with fungicides; It is important that
          afarme r sprays the potato crop imme diately after germination s pray with
          aprotectant such as dethane m 45 which is acontact fungicide that stays on
          the leaves to protect the plant. Incase the diseae sets in even after the farme r
          has sprayed with aprotectant, the farmer should s pray a second time using
          asystemic fungicide like Ridomil which enters the plant and heals from
          inside. Incase the disease persists, it is important for the farmer to s pray a
          third and the last time using a contact fungicide like the one we have already
          mentioned dethane M 45 to stop the disease from spreading.

18. PRES 2    But earlier on we were told that this disease can enter a farm from neibouring
              farms! The big question is. How does the disease spread?
              Dr. Betty Godwe

          When there is heavy rain, rain water washes the fungus spreading it to other
          leaves and even to othe r plants this continues and whe n the conditions are

              humid the disease spreads very quickly such that the farm can appear to be
              O.k today but when the farme r comes the following day finds the whole farm
              has been infected in one day.The disease will continue to spread from plant
              to plant and even from farm to farm. This is why we say even if you have
              used resistsnt variety you should spray with contact fungicide to prevent
              infection from other farms where the faemer may not have used resistant

19. PRESS 1 But Dr. Betty Gondwe. Incase the farmer does not take any step to control the
            disease when it comes what will happen?

          This is avery bad disease because if it starts to attack the leaves and the re is
          enough humidity with enough rain it will spread and a ffect the whole farm
          and we have seen that it attacks the leaves, branches and even the tubers.
          so all the leaves and branches will rot hence the whole plant will rot the refore
          the farmer will lose the whole crop or in other words total loss or 100% loss.

20. PRES 2    What aloss Lilian! The whole farm?

21 PRES 1     Ah! That should not scare you off Jared. She said that it is when the farmer does
              not follow the advice given! Infact here is Ms. Grace Ngatia explaining to farmers
              where they can access information to avoid such losses in their farms.

          For more information farmers can contact the agricultural offices/ offices at
          district ,divisional and locational levels. We also have leaflets which have
          been developed and are available from farm input outlets where farmers buy
          their inputs and also Kari research institutions are open to farme rs they can
          walk in and present their problems.

22 PRES 2     Very good news for farmers especially potato grower! They have leaflets and
              field officers ready to assist.

23 PRES 1     As if that is not enough , the research stations have open doors to farmers any
              time they can walk there and get assistance. Finally Ms. Grace Ngatia appeals to
              the farmers.

          I would appeal to our farme r to take note of what we have said in this
          programme especially knowing that the best way to prevent the disease is the
          use of clean certified seed which can be found from research stations, use of

             chemicals as recomended and use of resistant varieties which have been
             released from research stations.

 24 PRES 2   It is with that appeal that we end our investigation into the fungal disease Late
             blight today.

                            INSERT STING

 25 PRES 1   And now it is time to read our listeners letters and our competition.

 26 PRES 2   Am sorry Lilian, because of time we are not able to read and answer their letters
             but next week we will read letters and ask questions in our compe tition.

 27 PRES 1   Next week’s programme will focus on how the farmer can effectively spray and
             how the farmer can store the chemical for future use!

 28 PRES 1   Dear listener! With that we end our programme to- day! Incase you have a
             question you can write to us! Our address is P. O. Box 66730

29. PRES 2   On behalf of our producer Susan Moywaywa, and our client CIP these have been
             your presenters Jared Mukarebe....

30 PRES 1    With me Lilian Isindu.
