Abstract
FIELD TESTS WITH THE CHEMICAL BIRD REPELLENT "METHIOCARB" WERE CONDUCTED ON RIPENING WHEAT AT NANYUKI AND NAKURU, KENYA AND ON RIPENING RICE AT RUJEWA, TANZANIA. TWO OF THE THREE FIELD TESTS SHOWED THAT METHIOCARB, APPLIED AT A RATE EQUIVALENT TO 3 LBS. AL/ACRE, WAS EFFECTIVE IN REDUCING DAMAGE TO BOTH WHEAT AND RICE BY ABOUT 90%. RESULTS FROM THE THIRD TEST, WITH METHIOCARB APPLIED AT 1.5 LBS. AL/ACRE, WERE STATISTICALLY INCONCLUSIVE BECAUSE OF UNSEASONABLE RAINS AND UNEVEN BIRD PRESSURE. FURTHER TESTS OF THE CHEMICAL ON A LONG-TERM BASIS AND COLLECTION OF ADDITIONAL DATA ON THE QUELEA"S LIFE HISTORY ARE RECOMMENDED.
