In course of the research there was studied the effect of protective means on the productivity of winter rape (Brassica napus) oilseeds. The research was realized in the conditions of the Republic of Belarus in Gomel region (Rogachev) on light sod-podzolic pithy sandy loam soils. The agrochemical indicators of arable horizon were the following: humus content - 2.1%, pHKCl -6.0, P2O5 - 240 mg/kg, K2O - 285 mg/kg of soil. Spring cereals were preceding crops. In spring nitrogen in dose of N160 was applied twice (N100 - in the beginning of vegetation, N60 - in a bud-formation period) under winter rape. Protective measures on winter rape crops were realized according to a scheme of the experiment. As a result of realized research it was revealed that in winter rape crops the greatest seed yield (37.5 c/ha) was obtained by applying the full range of protective measures, such as: Butisan Star (2.0 l/ha), Lontrel (0.4 l/ha), Fusilade forte (2.0 l/ha), Fastak (0.15 l/ha), Decis Profi (0.05 l/ha), Alto Super (0.4 l/ha), New Film-17 (1.0 l/ha). Cost recovery amounted to 1.38 belarusian roubles.
