W075-Cotton Defoliation Timing [PDF]

open access: yes, 2010
Defoliation is an often-overlooked process that, if done properly, can pay large dividends. Defoliation is relatively easy in some situations and extremely difficult in others.

Screening for Fall Armyworm (Spodoptera frugiperda J. E. Smith) Resistance in Early‐Maturing Tropical Maize Adapted to Sub‐Saharan Africa

open access: yesPlant Breeding, EarlyView.
ABSTRACT Fall armyworm (FAW) (Spodoptera frugiperda J. E. Smith) has emerged as a serious pest since 2016 in Africa, affecting the food security and livelihoods of millions of smallholder farmers, especially those growing maize. Native genetic resistance to FAW is essential for reducing yield loss.

Revealing the Key Genetic Basis of Late Leaf Spot Resistance in Peanut by Combining QTL Mapping, QTL‐seq and RNA‐seq

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Late leaf spot (LLS) is the most widespread and destructive fungal disease affecting peanut worldwide, yet relatively little is known about its genetic basis. In this study, QTL mapping using a 1327‐bin map (derived from 9533 SNP/InDel markers) and multi‐environment phenotypic data repeatedly detected two major LLS‐resistance QTLs on ...

Tiller defoliation patterns under frontal, continuous, and rotation grazing.

open access: yes, 1994
An investigation was conducted to characterize the intensity and frequency of tiller defoliation in 'Plains' Old World bluestem (Bothriochloa ischaemum (L.) Keng) under frontal, continuous, and 2-paddock rotation grazing systems.

Impact of cultural practices on two‐spotted spider mite (Tetranychus urticae Koch) infestation in tomato cultivation in the Central Rift Valley of Ethiopia

open access: yesCrop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.
Abstract The two‐spotted spider mite (TSSM; Tetranychus urticae Koch) is a major pest of tomato (Solanum lycopersicum L.), causing substantial yield and quality losses in Ethiopia and worldwide. The present study evaluated the impact of tomato branch pruning and trellising on TSSM populations and yield in the Central Rift Valley tomato production area ...

Enhancing spring green‐up of warm‐season turfgrasses through late‐winter scalping

open access: yesCrop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.
Abstract Rapid spring green‐up of warm‐season turfgrasses in the transition zone is often desired to improve early‐season turfgrass quality, thereby increasing the acceptance of these species in arid and semi‐arid climates. This study evaluated the effects of late winter scalping on spring green‐up speed in 41 cultivars of bermudagrass (Cynodon spp ...

The effect of frequency of defoliation on Themeda triandra in the false thornveld of the eastern Cape.

open access: yes, 1989
Tufts of Themeda triandra were subjected to different frequencies of defoliation during a single season under irrigated and non-irrigated conditions. Frequent defoliation (> 5 times per year) severely reduced clipped yield on both moisture treatments. On

Sustained Livestock Grazing Enhances Soil Organic Carbon Storage in Sub‐Arctic Grassland

open access: yesGlobal Change Biology Communications, Volume 1, Issue 4, December 2026.
We studied long‐term effects of grazing cessation on 34 grassland and heathland sites in Iceland. Grazing cessation was associated with lower SOC, nitrogen and root carbon in the top 10 cm of soil providing evidence for enhanced SOC in grazed land, showing that grazing is a climate change mitigation strategy.

Determination of the impact of continuous defoliation of Lolium perenne and Trifolium repens on bacterial and fungal community structure in rhizosphere soil

open access: yes, 2005
To determine the effects of defoliation on microbial community structure, rhizosphere soil samples were taken pre-, and post-defoliation from the root tip and mature root regions of Trifolium repens L. and Lolium perenne L.

Multiple ortho‐mosaicking software pipelines produce comparable imagery‐derived wheat phenotypes

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Unmanned aerial systems (UAS) equipped with multispectral and RGB sensors offer valuable data for monitoring crop health and assessing disease severity. However, the wide range of available photogrammetric software complicates software selection for high‐throughput plant phenotyping.
