• AFTER PLANTING ON THE 11/11/2020.

TOGAREPI IN HIS LANDS AFTER PLANTING WAS COMPLETED.

AFTER 1 WEEK ALL SEEDLINGS HAD TAKEN. ORIGINALLY TOGAREPI USED TO PUT AN IN THE PLANTING HOLE WHICH WE ADVISED HIM NOT TO AND TO RATHER PUT AN AFTER 2 WEEKS. HE SAID THE CROP HAD TAKEN MUCH BETTER WITHOUT THE AN IN THE PLANTING HOLE.

DUSTY SURFACE BEETLE HAD BEEN FOUND IN THE LANDS. WE DUG AROUND THE STEMS IN ROWS 4,5,6,7&8 WHERE WE USED 400MLS/HA OF CYANTRANILIPROLE IN THE PLANTING WATER AND FOUND THERE WAS NO DAMAGE.

2 WEEKS AFTER PLANTING. DUSTY SURFACE BEETLE WAS STILL AROUND BUT NO DAMAGE HAD BEEN DONE TO ANY OF THE ROWS.

A CLOSE UP OF THE STEM OF A PLANT IN ROW 5. THERE ARE INSECTS AROUND BUT THERE IS NO DAMAGE TO ANY OF THE TOBACCO.

04/01/2021 ALL ROWS ARE APHID FREE AND NO INSECT DAMAGE IS VISIBLE ON ANY OF THE TOBACCO PLANTS

A SINGLE TOBACCO PLANT

FROM ROW 3

11/01/2021 ALL ROWS WHERE FLUMETRALIN DUO HAD BEEN USED THE SUCKERS WERE STILL SHOWING. (ALL THE SUCKERS WERE DISTORTED)

11/01/2021 ALL ROWS WHERE N’DECANOL HAD BEEN USED THE SUCKERS HAD BEEN BURNT AND HAD FALLEN OFF.

ALL TRIAL ROWS ARE FREE OF ANY INSECTS AND APHIDS.

TOGAREPI’S TOBACCO (IN A DIFFERENT FIELD) HAS SOME INSECTS. THERE DOESN’T SEEM TO BE MUCH INSECT DAMAGE BUT THE INSECTS ARE PRESENT.

A FEW PLANTS HAD BEEN

AFFECTED BY WIND DAMAGE.

A TOBACCO PLANT FROM ROW 1 AND ROW 6 HAVE BEEN PULLED AND SENT TO KUTSAGA FOR

NEMATODE TRIALS.

ALL THE SUCKERIDES THAT HAD BEEN APPLIED HAD STARTED WORKING AND BURNT THE SUCKERS AND CAUSED THEM TO BECOME DISTORTED

BUD WORM HAD BEEN FOUND ON ONE TOBACCO PLANT IN ROW 10. ONLY THE PLANT WHERE BUD WORM WAS SEEN WAS THERE ANY DAMAGE VISIBLE TO THE

LEAVES. ALL OTHER PLANTS IN ALL ROWS HAD NO DAMAGE.

ROW 10 AND 9 HAVE SOME LARGE SUCKERS ON THEM. ALTHOUGH THEY SEEM TO BE DISTORTED, THEY ARE STILL GROWING.

27/01/2021

• TOGAREPI IS ABOUT TO START REAPING HIS TOBACCO FROM THE TRIAL AREA.

ROW 10 STILL HAS SOME BUD WORM AND ARMY WORM, WHICH HAS DAMAGED A FEW OF THE LEAVES.

05/02/2021THE TOBACCO IS ALL UNIFORM.

ROWS 1,8,9 &10 ALL HAVE LARGE SUCKERS. THE ROWS WHERE FLUMETRALIN DUO HAS BEEN USED HAVE NO SUCKERS. (THOSE WERE THE ROWS WHICH HAD SUCKERS FIRST AND NOW THEY ARE FREE OF SUCKERS)

ROW 10 HAS LACE WORM IN IT. SOME PLANTS DON’T SEEM TO HAVE ANY ARMY WORM OR ANY DAMAGE FROM ANY ARMY WORM HOWEVER SOME PLANTS HAVE ONE OR SOMETIMES TWO LACE WORMS PER PLANT.

TOGAREPI’S TOBACCO IN HIS BARNS. HEAT SEEMS TO BE HIS BIGGEST ISSUE IN THE

BARNS.

15/02/2021 TOGAREPIS CROP IS LOOKING HEALTHY AND HIS REAPING ON THE TRIAL AREA IS ALMOST COMPLETE

AFTER THE TOBACCO HAS BEEN THROUGH THE BARNS WE WILL RECORD AND COMPARE THE WEIGHTS OF THE LEAVES FROM EACH ROW AND EACH REAPING

23/02/2021 THREE REAPINGS HAVE BEEN DONE SO FAR FROM THE TRIAL AREA.

THE TOBACCO IN THE BARNS FROM THE TRIAL AREA IS FREE OF ANGULAR. IN THE FIRST PICTURE YOU CAN SEE THE TOBACCO FROM ROW 4 WHERE BION WAS USED AGAINST THE TOBACCO FROM TOGAREPIS CROP WHERE NO BION WAS USED.

AFTER TWO REAPINGS THE FOLLOWING WEIGHTS WERE RECORDED.

ROW 2 FIRST REAPING

TOGAREPI’S CROP AFTER REAPING. THE ROWS WHERE FLUMETRALIN DUO HAD BEEN USED HAD NO ‘SUCKERS AND FLOWERS WHEREAS THE ROWS WHERE N’DECANOL HAD BEEN USED HAD SUCKERS AND FLOWERS ON THE STRIPPED STALKS.

TOGAREPIS CROP THAT WAS PLANTED AT THE SAME TIME HAS FINISHED BEING

REAPED, THE TRIAL CROP STILL HAS UP TO SIX LEAVES ON SOME PLANTS.

ALL THE TOBACCO HAS BEEN REAPED AND THE LAST THREE REAPINGS ARE IN THE BARNS.

15/3/2021 ALL OF THE TOBACCO HAS BEEN REAPED AND CURED. THE FOLLOWING RATES WERE WHAT WE RECORDED FOR EACH ROW.

FINAL SUMMARY CHEMICALS BELIEVED TO HAVE BENEFITED THE

TOBACCO IN EACH ROW

SUMMARY

• ROWS WHERE BION WAS APPLIED HAD A BETTER RECORDED WEIGHT OVER THE ROWS WHERE NO BION WAS APPLIED.

• ROWS WHERE CALSAP OR EZYFLOW LIME WAS APPLIED HAD A BETTER RECORDED WEIGHT OVER ROWS WHERE NO CALSAP OR EZYFLOW LIME HAD BEEN APPLIED.

• THE SUCKER CONTROL WAS BETTER ON THE ROWS WHERE FLUMETRALIN DUO HAD BEEN APPLIED RATHER THAN THE ROWS WHERE N’DECANOL HAD BEEN APPLIED.
