Karel Sikora
Poppy seed (Papaver somniferum L.) is an annual autumn or spring plant. This crop is cultivated generally for seed which is used as a foodstuff in food processing industry. The biological efficacy of different tested active ingredients (lambda-cyhalothrin, bifenthrin, aplha-cypermethrin, DE-225 and combination chlorpyrifos + cypermethrin) on poppy weevil (Stenocarus ruficornis S.) was evaluated in comparison with reference active ingredient (carbofuran) used as a standard treatment. The active ingredients were applied against the mentioned pest once in the season and were used in doses which were similar to those used against stem weevils in winter oil seed rape. Reference active ingredient was used in the dose which was authorised in the Czech Republic as standard ones against the poppy weevil. All active ingredients revealed efficacy which was measured (as a size of injuries) both on leaves and roots. Two trials were performed in 2001–2002 in which efficacy and selectivity were assessed.
