Strip Crops and Intercrops Outperform Crop Rotations for Weed Management Under Conservation Agriculture in Zimbabwe

open access: yesWeed Research, Volume 66, Issue 1, January/February 2026.
ABSTRACT High weed infestation remains a major constraint on crop productivity for smallholder farmers practising Conservation Agriculture (CA). Fewer, more diverse weeds are desirable to reduce competition and provide ecosystem services. Crop diversification can help, but it is not yet clear which species combinations and layouts are most effective ...

Ecological Diversity of Summer Maize Weed Species in the Western Mid‐Hills of Nepal

open access: yesInternational Journal of Agronomy, Volume 2026, Issue 1, 2026.
Maize (Zea mays L.) cultivation in the mid‐hills of Nepal is vital for food security but faces significant yield losses due to weed competition. The two‐year (2023–2024) phytosociological study on summer maize was conducted to assess weed diversity and dynamics in randomly selected 40 farmers’ fields of Puranchaur, Dhikidada, Gharmi, and Lamachaur at ...

Impact of Pre‐Emergent Herbicides and Soil Management on Weed Community Dynamics and Soybean Yield

open access: yesInternational Journal of Agronomy, Volume 2026, Issue 1, 2026.
Pre‐emergent herbicides are key tools in managing herbicide‐resistant and hard‐to‐control weed species in soybean (Glycine max L.) cultivation. This study aimed to evaluate the effects of pre‐emergent herbicides on weed phytosociology, soybean phytotoxicity, and grain yield under different soil management systems and environmental conditions.

The immature stages and biology of two Xenapates species in West Africa (Hymenoptera, Tenthredinidae) [PDF]

open access: yes, 2016
The immature stages and host plants of Xenapates Kirby, 1882 were hitherto unknown. We describe the larvae, prepupae and pupae of X. braunsi (Konow, 1896) and X. gaullei (Konow, 1896), and record observations on aspects of their biology. The relationship
