Take flight: predation risk induces wing polyphenism and dispersal in the aphid Myzus persicae

Pest Management Science, EarlyView.
Predator risk above a critical density induces winged morphs in Myzus persicae, promoting dispersal and reducing predation compared with wingless aphids. This density‐dependent phenotypic plasticity enhances survival but may compromise biological control by facilitating aphid dispersal.

The effect of catch crops cultivated in accordance with the agri-environment scheme on weed infestation of spring wheat stand

Plant, Soil and Environment, 2016
The aim of the conducted study was to assess the effect of two types of stubble catch crops (a mixture of legumes and white mustard) as well as varied nitrogen fertilization on weed infestation of a spring wheat stand depending on the adopted tillage ...

Interference Periods of Weeds Infesting Maize Crop

Journal of Agricultural Science, 2018
When competing with crops, weeds interfere with their growth and consequently reduce grain yield. The purpose of this research was to determine the periods of interference; PIP (pre-interference period), TPWC (total period of weed control), and CPWC (critical period of weed control) of the weeds Alexandergrass (Urochloa plantaginea) and southern ...

Controlled incubation, leachate, and pot assays of shrimp shell‐based compost for suppressing Verticillium dahliae in olive

Pest Management Science, EarlyView.
Shrimp shell compost suppresses Verticillium dahliae microsclerotia, enhances chitinase activity, lowers olive wilt severity and improves plant recovery under controlled conditions. Abstract BACKGROUND Verticillium wilt of olive (Olea europaea L.), caused by Verticillium dahliae Kleb., is difficult to manage because long‐lived microsclerotia persist in

Weed Tolerance and Suppressive Ability of Potato Cultivars to Natural Weed Infestations

Journal of Crop Health
Abstract Concerns such as herbicide-resistant weeds and environmental pollution have increased an interest in using weed-competitive crop cultivars for weed management. Potato plants are highly vulnerable to weed competition, especially during early and late growing seasons. In this context, a two-year field experiment assessed weed tolerance

Procedures of image analysis for weed recognition in cereals [PDF]

, 2012
An automatic weed recognition system is a prerequisite for site specific weed control when using weed threshold concepts. Segmentation, a preprocessing step, is applied to two- or three-dimensional images. In the following step, methods of graph matching,

Sublethal herbicide exposure alters cotton susceptibility to aphid infestation

Pest Management Science, EarlyView.
Sublethal herbicide exposure altered cotton susceptibility to aphids. Aphid severity was highest when applications occurred at early vegetative stages and declined as the crop matured. In glasshouse, herbicide effects were dose‐dependent. Abstract BACKGROUND Herbicides remain vital tools for weed control, yet their effects can extend beyond weeds to ...

Biocontrol and plant growth‐promoting potential of Streptomyces strains against fungal pathogens of tomato and wheat for a sustainable agriculture

Pest Management Science, EarlyView.
This study highlights the biocontrol potential of Streptomyces strain Strep_22. In vitro, it inhibits key fungal pathogens by 91.52%. In vivo, it significantly reduces disease incidence in wheat and tomato while enhancing biomass, shoot, and root development, offering a highly promising, sustainable ecological alternative to chemical pesticides ...
