PURPOSE:An agrochemical dust that contains agrochemical active ingredients, a mineral dust carrier and a hydrocarbon tackifier such as process oil, thus showing reduction in dusting, flying and drifting with increased storage stability and efficacy. CONSTITUTION:The objective agrochemical dust is composed of agrochemical active ingredients, a mineral dust carrier such as clay, silica or calcium carbonate, and a hydrocarbon tackifier. The resultant dust shows inexpensively improved drifting without any adverse effects on adhesion, spreadability and absorption in the plant bodies and the decomposition of the agrochemicals can be prevented. The hydrocarbon tackifier is, e.g., ethylene-alpha-olefin oligomer, or a mixture thereof with isobutylene oligomer, process oil or butadiene oligomer or a mixture thereof with isobutylene oligomer and the amount thereof is 0.2-5.0pts.wt. per 100pts.wt. of the dust.
