A Guide to Integrated Pest Management for Brassica - Insect Pest, Disease, Virus, Nematode and Weed Control [PDF]

open access: yes, 2010
This guide outlines the key issues that should be considered in relation to the implementation of Integrated Pest Management (IPM) for brassica crops on a whole of crop basis.

Synthetic polymer nanocarrier enhances dsRNA stability but not RNAi efficacy in Brassicogethes aeneus

open access: yesPest Management Science, EarlyView.
Experimental setup for dsRNA feeding in Brassicogethes aeneus to evaluate the effect of a synthetic polymer nanocarrier on RNAi efficiency. The experiment assessed whether the nanocarrier enhances RNAi after oral dsRNA delivery. (a) Stability of dsRNA–nanocarrier complexes was tested in simulated gut conditions. (b) Gene expression of αCOP and dre4 was

Studies on Bolting in Brassica

open access: yesJournal of the Japanese Society for Horticultural Science, 1969
It had observed that after flowering, the axillary buds were growing vegetatively in C-genome varieties of Brassica. This phenomenon is called“Semi-vegetative growth”. In this experiment, semi-vegetative growth was studied. Several varieties with different ecotypes in C-genome were used. The seeds were sowed in Autamun 1967 and the plants were grown in

Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape

open access: yesPest Management Science, EarlyView.
Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.

Biochar and trehalose synergistically mitigate antimony toxicity in Brassica napus by enhancing physiological functions and stress-responsive gene expression

open access: yesNotulae Botanicae Horti Agrobotanici Cluj-Napoca
Antimony (Sb), a toxic metalloid, severely threatens crop productivity and human health. Biochar (BC) and trehalose (Tre) are known individual stress mitigators, but their combined effect against Sb toxicity remains unexplored.

Evolution of linked avirulence effectors in Leptosphaeria maculans is affected by genomic environment and exposure to resistance genes in host plants

open access: yes, 2010
Brassica napus (canola) cultivars and isolates of the blackleg fungus, Leptosphaeria maculans interact in a ‘gene for gene’ manner whereby plant resistance (R) genes are complementary to pathogen avirulence (Avr) genes.

Temporal dynamics of co‐inoculation of Leptosphaeria maculans and Leptosphaeria biglobosa determine interspecific competition and disease development on oilseed rape

open access: yesPest Management Science, EarlyView.
This study provides evidence that the timing of co‐inoculation of Leptosphaeria maculans and Leptosphaeria biglobosa determine the outcome of interspecific competition and disease development on their host oilseed rape. Abstract BACKGROUND Phoma stem canker is one of the most economically damaging diseases of oilseed rape, caused by co‐existing fungal ...

Seedling resistance and chemical defenses against Psylliodes chrysocephala: the roles of seed age and sinapinic acid in Sinapis alba and Brassica napus

open access: yesPest Management Science, EarlyView.
The cabbage stem flea beetle (Psylliodes chrysocephala) is a major pest of winter oilseed rape (Brassica napus). We tested B. napus and Sinapis alba seedlings for feeding resistance and underlying chemical defenses. S. alba was least damaged, while metabolite profiles revealed resistance‐linked compounds, highlighting breeding potential for insect ...

Community composition, abundance and activity‐density of carabids and staphylinids depend on prey abundance and adjacent habitat even in diverse agricultural landscapes

open access: yesPest Management Science, EarlyView.
Carabid and staphylinid communities are shaped by adjacent habitat type, prey availability and landscape context, influencing natural pest control across agricultural landscapes. Abstract BACKGROUND The functioning of agroecosystems depends on key ecosystem processes that deliver ecosystem services, yet agricultural management has increasingly shifted ...

Parasitoid load affects plant fitness in a tritrophic system

open access: yes, 2008
Plants attacked by herbivorous insects emit volatile compounds that attract predators or parasitoids of the herbivores. Plant fitness increases when these herbivorous insects are parasitized by solitary parasitoids, but whether gregarious koinobiont ...
