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

Pest 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.

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

Pest 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 ...

Determining frequencies of fungicide resistance in Leptosphaeria maculans that render demethylation inhibitor fungicides ineffective in the field

Pest Management Science, EarlyView.
As little as 1–10% of the population is needed to be resistant for demethylation inhibitor fungicides to be rendered ineffective. Following a single round of selection, the frequency increases by more than 15% with limited fitness penalty detected when no selection is present.

A Trp574–Leu substitution confers resistance to three classes of acetolactate synthase inhibitors in Australian brome grass (Bromus diandrus)

Pest Management Science, EarlyView.
Target‐site based imidazolinone resistance in brome grass was found to be conferred by a mutation at position 574 in the ALS gene and to severely impact the efficacy of the herbicide Intervix®, a co‐formulation of imazamox and imazapyr. Abstract BACKGROUND Brome grass (Bromus diandrus) is a prevalent weed in southern Australian cropping regions which ...

Breeding maize under biodynamic-organic conditions for nutritional value and N efficiency/N2 fixation

Open Agriculture, 2019
An overview is given for an ongoing maize breeding program that improves populations, inbreds, and hybrids in the Midwestern USA. Breeding and selection occurred under biodynamic conditions in Wisconsin, on an organic winter nursery in Puerto Rico, a ...

Host plant‐specific volatiles of Beauveria bassiana‐colonized plants initiate trophic plant–aphid–predator cascades

Pest Management Science, EarlyView.
Endophytic colonization of melon plants by B. bassiana modifies the crop volatile profiles in a genotype‐dependent manner. A predator choice is biased toward endophytically colonized plants infested with aphids revealing a guardian within effect of the fungus of great potential in integrated pest management.

Essential oils as bioherbicides: effects of orange and citronella oils on weed germination and early growth

Pest Management Science, EarlyView.
Essential oils from orange and citronella showed dose‐dependent inhibition of weed germination and early growth, highlighting their potential as bioherbicides and sustainable tools for integrated weed management. Abstract BACKGROUND Increasing selection of herbicide‐resistant weed biotypes has intensified the search for alternatives to the intensive ...

Disease control in oilseed rape: Current insights and perspectives for next‐generation integrated pest management

Pest Management Science, EarlyView.
Winter oilseed rape in Europe suffers frequent pathogen losses. This review outlines key integrated pest management (IPM) strategies, rotation, residue and tillage management, optimized sowing, resistance, and targeted fungicides supported by forecasting.
