Item An Attempt to Reduce the Cost of Pyrethrum Aerial Sprays against Glossina Swynnertoni Aust. In Savannah Woodland(1972) Tarimo, C. J.; Parker, J.D.; Kahumbura, J.MAn air spray experiment carried out with percent synergized pyrethrum in power kerosene against Glossina swynnertoni Aust. and Glossina pallidipes Aust. in savannah woodland indicated that pyrethrum might be used effectively and economically to control tsetse from the air (Tarimo et a 1971b). The cost per hectare after three applications of the pyrethrum formulation was £0.3848 (£99.7 per square mile), but it was felt that the cost might be lowered either by using a lower concentration of the spray formulation or by extending the swath width. In this experiment, an attempt was made to reduce the cost by using a lower concentration of the pyrethrum formulation.
