Plant protection products in root vegetable

Abstract

The production, value and quality of root vegetables are endangered by numerous phytopathogenic fungi and pests. Numerous causal agents cause economically significant diseases of root vegetables like carrot leaf blight and black rot of carrots (Alternaria dauci and Alternaria radicina), powdery mildew of carrot and sugar beet (Erysiphe heraclei and Erysiphe betae), Cercospora leaf spot of carrot (Cercospora carotae), black blight (Septoria apiicola), leaf bright parsley (Septo-ria petroselini), downy mildew (Peronospora farinosa f.sp. betae and P. farinosa f.sp. spinaciae), rust (Puccinia spp.) etc. Nine fungicides based on nine different active substances have been registered in the Republic of Serbia for the control of phytopathogenic fungi in root vegetable crops. The most important pests of root vegetables are wireworms (Elateridae), carrot flies (Psila rosae), celery flies (Acidia heraclei), onion flies (Delia antiqua), aphids (Aphididae), common spider mite (Tetranychus urticass), cabbage moth (Mamestra brassicae), cotton bollworm (Helicoverpa armigera) and others. The overall number of insecticides, registered in our country, for the control of root vegetable pests is eight, based on seven different active substances. The aim of this paper is to present registered plant protection products for the control of the most economically import-ant pathogens and pests of root vegetables, in the Republic of Serbia, classified according to the mode of action.
