Efficacy of microbiological treatments and trap crop against pests of winter oilseed rape
نویسندگان
چکیده
Winter oilseed rape was cultivated in monoculture or in combination with turnip rape as trap crop sown in trap strip. Preventative microbiological treatments for diseases control in winter oilseed rape were tested using Trichoderma asperellum and product based on effective microorganisms. Microorganisms were effective to protect of oilseed rape and allowed to obtain higher yield comparing to untreated plants. No effect of turnip rape as trap crop stripe on infestation by insect pest was observed. There was no statistically significant influence of presence B. rapa on total yield. Statistically higher percentage of infected pods collected from area with turnip rape compared to monoculture area was noted.

Oilseed rape (Brassica napus) is an important combinable break crop in the UK, which is largely protected from arthropod pests by insecticidal chemicals. Despite ongoing debate regarding the use of neonicotinoids, the dominant seed treatment ingredients used for this crop, there is little publicly available data comparing the efficacy of insecticides in controlling key arthropod pests or compar...
متن کاملCharacterization of the pollen beetle, Brassicogethes aeneus, dispersal from woodlands to winter oilseed rape fields
Many crop pests rely on resources out of crop fields; understanding how they colonize the fields is an important factor to develop integrated pest management. In particular, the time of crop colonization and damage severity might be determined by pest movements between fields and non-crop areas. Notably, the pollen beetle, Brassicogethes aeneus, previously named Meligethes aeneus, one of the mo...

Management of nitrogen fertilization in crops is one of the most important components of integrated weed management. A two-year field experiment was conducted to determine the direct effects of wild mustard aboveground biomass and N content of wild mustard on oilseed rape yield. A set of factorial treatments was arranged in a randomized complete block design with four replications. Treatments w...
متن کاملTransformation And Light Inducible Expression of cry1Ab Gene in Oilseed Rape (Brassica napus L.)
Rapeseed (Brassica napus L.) is the third most important oil crop in global productions. One of the major limiting factors for oilseed rape production is lepidopteran pests of the Brassicaceae family. Transgenic plants expressing Bacillus thuringiensis (Bt) genes are powerful tools in the integrated pest management of crop plants. In the present study, we used a synthetic Bt insecticidal crysta...

greater than CO2 (Callander et al., 1995). Therefore, the objective of the present work was to quantify the annual emission of N2O from winter rye, M. ‘Giganteus’ and winter oilseed rape. Furthermore the N2O emission will be related to the estimated net CO2-displacement. The annual emissions of N2O were measured using a closed-chamber technique and were based on results obtained by Jørgensen et...
