The work was done in years 1998/1999 - 2000/2001 on plantations and field plot experiments. Aim of the work was evaluation of take-all occurrence on winter wheat in milk-wax growth stage in dependence on forecrop (oilseed rape, wheat or barley) as well as seed treatment with Latitude 125 FS when wheat was planted on fields after wheat or barley. Percentage of infected plants when seeds were not treated with Latitude 125 FS varied from 82-100 on fields after wheat or barley, and 54-69 on fields after oilseed rape. In treatments with wheat grown after wheat or barley the percentage of infected plants amounted 20-100 when seeds were not treated with Latitude 125 FS and 13-86 when seeds were treated with Latitude 125 FS. Mean degree of infection was low when percentage of infected plants was low and high when percentage of infected plants was high.

Seed treatment with mineral nutrients in spring oilseed rape (SOR) under cold climatic conditions has the potential to improve the outcome of production. The objectives of this study were to investigate the effects of mineral nutrients applied as seed treatment on germination and growth of roots and biomass in SOR. In addition, seed yield and oil content were also measured. Seed vigour tests and in-field experiments were performed in Central Sweden in 2016 and 2017. Seven products with different composition of mineral nutrients were applied to the seed in a combination with binder, filler and fungicide (BFF), or applied directly onto the seed. The results showed that a treatment with mineral nutrients increased the plant size at stage BBCH 60 (early flowering stage) when the products were applied in combination with BFF in the field experiments. However, the increased plant size did not influence seed yield. Furthermore, when seeds were treated only with a nutrient product the addition of BFF decreased plant size by 10% on average and seed and crude fat yields by 4% on average. The use of BFF may thereby be questioned and is subject to further investigation.

The Impact

Small plot trials studying the impact of different seed treatments on the occurrence of pests and diseases in autumn were carried out during 2000–2003. The aim was to verify the efficiency of different fungicidal and insecticidal oilseed rape seed treatments and to determine the economical effectiveness of this method of protection. The following insecticidal seed treatments were used: Promet 400 CS (furathiocarb), Cosmos 500 FS (fipronil), Chinook 200 FS (imidacloprid & beta-cyfluthrin) and Marshal ST (carbosulfan). The seed treatment Chinook 200 FS in combination with newly developed fungicidal compound was also assessed. The most effective treatment was Chinook 200 FS (imidacloprid & beta-cyfluthrin), particularly against flea beetles (Phyllotreta spp.), and lower infestations by larvae of the turnip gall weevil (Ceutorhynchus pleurostigma Marsh.) were also found. However, the efficiency lasts no more than 4–5 weeks after sowing. The use of common insecticidal treatments in cases of necessity was found to be beneficial. Plant density in autumn and in spring was greatest in the Chinook 200 FS treatment and in some years a positive influence on yield was also observed with this treatment.

Abstract The risk exposure of bee colonies to the toxicity of systemic neonicotinoid insecticides was assessed. Various methods of chemical prevention of commercial winter and spring oilseed rape crops in field-realistic conditions were taken into account in the assessment. Pesticides were applied in accordance with the actual agricultural practice. Commercial crop protection products with thiamethoxam, clothianidin or imidacloprid were used as seed treatment. Formulations containing acetamiprid or thiacloprid were used for spraying. Fifteen healthy bee colonies were placed in close proximity to each of the oilseed rape fields throughout the blooming period. During florescence, the samples of nectar (directly from flowers and nectar flow from combs) and pollen loads were collected repeatedly. Samples of honey, bee bread and adult bees were taken one week after the end of plants flowering. To ensure high specificity and sensitivity of analysed pestcicides modified QuEChERS extraction method and liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) was used. The five of neonicotinoid insecticides (imidacloprid, clothianidin, thiametoxam, acetamiprid and thiacloprid) were analyzed in multi-residue method with 0.1 - 10 ng/g limits of detection. Palynological analysis was done to determine the botanical origin of the nectar, honey and pollen. Development of bee colonies (brood area, worker biomass, colony health) was assessed every 3 weeks until the end of the beekeeping season. The amount of pollen collected by bees per hive, bee bread area and rape honey yield was also measured. The long-term effects of insecticides on bees were estimated using the same methods in April of the following year. All the neonicotinoid insecticides applied to control oilseed rape pests were present in the samples of nectar and pollen. Their residue levels were lower than the acute oral and contact LD50 values. Among five examined neonicotinoids, the most frequently detected were: thiamethoxam, thiacloprid and acetamiprid. These substances were present in 65, 64, and 51% of the nectar samples and in 37, 62, and 45% of the pollen samples, respectively. The highest level of residues were noted after the thiamethoxam seed treatment; on average, 4.2 and 3.8 ng/g in the nectar and pollen samples. In the nectar and pollen samples from winter rape fields, lower levels of neonicotinoid residues were found in comparison to spring rape samples. The contaminations of neonicotinoids applied as seed dressing in nectar samples were significantly higher in comparison to the pollen samples. No negative effects of neonicotinoids on the bee mortality, brood development, strength, and honey yield of healthy bee colonies were found throughout the study period. However, the risk exposure of bee colonies on adverse impact of pesticide residues is high in areas of intensively cultivated oilseed rape.
