Abstract

Abstract: Effects of imidacloprid (Gaucho) coating on aphids in fields of oilseed rape were studied. Seeds were treated by Gaucho in different ratios of 1∶5, 1∶25 and 1∶125 (weight of chemicals versus seeds). The results showed that vegetative growth (plant height, leaf area, number of leaves, chlorophyll contents and plant weight) at seedling-stage and reproductive growth at flowering-stage (flower size, flower weight, proline/soluble protein/ soluble sugar and starch contents in the flowers) were not significantly affected by treatments; but the fruiting was significantly inhibited, i.e. empty pods were increased as the treated concentration elevated, size/weight/ seeds of pods together with the seeds weight were significantly decreased. Results above suggested that imidacloprid as a seed-coating agent could significantly affect the fruiting, but showed no effect on the seedling and flowering of oilseed rape.

Key words: seed-coating agent, imidacloprid, oilseed rape, field population
