Soil‐dependent variation in strigolactone signaling distance revealed by a parasitic seed germination bioassay

open access: yesPest Management Science, EarlyView.
A parasitic seed germination bioassay reveals strong soil‐dependent variation in strigolactone signaling distance, controlled by physical and biological soil properties, which shapes signaling range and parasitic weed infection risk. Abstract BACKGROUND Strigolactones are root‐exuded plant metabolites acting as germination stimulants for several ...

Response of 10 Elite “Green Super Rice” Genotypes to Weed Infestation in Aerobic Rice Systems

open access: yes, 2015
In recent years, water and labor shortage in Southeast Asia is driving the farmers towards dry-seeded rice systems. Weed infestation is a serious threat for adoption of these systems.

2‐Amino‐3H‐phenoxazin‐3‐one is a lead inhibitor of Cuscuta campestris early development: structure–activity relationships of o‐aminophenol‐derived allelochemicals

open access: yesPest Management Science, EarlyView.
Phenoxazinones caused differential types of phytotoxic effects in C. campestris early development. APO is a coherent lead inhibiting C. campestris germination and early seedling growth. Abstract BACKGROUND 2‐Amino‐3H‐phenoxazin‐3‐one (synonym: questiomycin A; abbreviated as APO or Phx‐3) is a naturally occurring phenoxazinone‐type allelochemical with ...

Wpływ zróżnicowanej uprawy roli i pielęgnacji roślin na zachwaszczenie łanu jęczmienia jarego

open access: yesAgronomy Science, 2004
A 4-year-field experiment (2000–2003) carried out on loessial soil in the central Lublin Region evaluated the influence of four systems of soil tillage (conventional, simplified with intercrop, simplified and direct sowing) and plant cultivation on the ...

Investigations on the weed suppression in sole and intercropped stands of winter peas of contrasting growth habit

open access: yesJulius-Kühn-Archiv, 2014
Currently, normal-leafed long-vined and semi-leafless short-vined winter pea cultivars are available commercially. The weed infestation in pea crop stands is affected by both pea growth habit and cropping system.

Mortality in an invasive ant does not scale linearly with fipronil exposure

open access: yesPest Management Science, EarlyView.
Increasing fipronil concentration did not linearly increase yellow crazy ant mortality when introduced via horizontal transfer; high doses may limit food sharing. Queen mortality was low, and surviving workers were averse to feeding. Abstract Background Controlling eusocial invasive and other pestiferous insects is difficult.

The impact of different weed control methods on weed infestation in maize (Zea mays L.) [PDF]

open access: yesActa agriculturae Serbica, 2019
The aim of the study was to evaluate the occurrence and development of weed species as actual weed infestation of maize in sustainable farming systems. The specific goals of the study were to assess the dynamics of occurrence of each weed species in integrated and ecological farming systems, and to evaluate the impact of farming system, manure or ...

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

open access: yesPest 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.
