Stacking tools on a wheel hoe to improve weed control for small-scale farmers

Weed Technology
Small-scale vegetable farmers rely on hand tools for weed management, including wheel hoes, stirrup hoes, and tine rakes. They also pull weeds by hand in crop rows, with costs increasing in proportion to weed density.

A composite, host‐participatory haustorium links host compatibility to defence bifurcation in Alectra vogelii (Orobanchaceae)

PLANTS, PEOPLE, PLANET, EarlyView.
Parasitic weeds of the family Orobanchaceae are among the most damaging constraints on food production in the tropics, draining water and nutrients from their hosts and threatening the livelihoods of millions of smallholder farmers. Yellow witchweed (Alectra vogelii) can destroy entire legume harvests across sub‐Saharan Africa, where these crops are a ...

Impact of seedbed preparation and macro-fertilizers on yield and radiation use efficiency (RUE) of rainfed chickpea growth under weed competition

Discover Sustainability
Sustainable intensification of rainfed chickpea (Cicer arietinum L.) production relies on optimizing agronomic practices, especially in seedbed preparation, fertilization, and weed control.

Ryegrass and wild radish seed bank dynamics and wheat yield under management strategies

Pesquisa Agropecuária Tropical
In cropping systems, the persistence of weed seed banks is a major challenge for sustainable weed management. This study aimed to evaluate the efficiency of pre-sowing and post-emergence herbicide management, combined with pre-harvest ...

Carbon sequestration strategies for climate resilience: Sorghum‐based innovations for sustainable agriculture in dryland regions

PLANTS, PEOPLE, PLANET, EarlyView.
Climate change is intensifying heat, drought, and food insecurity, threatening dryland farming and carbon management worldwide. We reviewed research on sorghum, a drought‐adapted C4 crop, covering physiology, roots, biomass allocation, soil carbon, bioenergy, breeding, phenotyping, management, and policy.

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

Pest 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 ...

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

Pest 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 ...

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

Pest 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.
