Farmers were interviewed on the management of the heartwater burden within their respective sub-districts and they reported that their animals were affected by heartwater despite 17 out of the 27 farmers interviewed attempting to control vectors through acaricide use. (bvsalud.org)
Githaka said the rise of acaricide resistance in Africa is mainly due to farmer misuse of these chemicals including, under-dosing, more frequent acaricide application than is necessary, poor chemical mixing, failure to rotate in other tick repellants when resistance is noticed and, in many cases, use of inferior products and counterfeits.
