Relationship between soybean plant defoliation and Asian soybean rust severity

, 2019
Data from experiments conducted in the field with eight fungicide mixtures added of five mancozeb levels were used to generate gradients of soybean rust severity, plant defoliation, and soybean grain yield. The data were subjected to correlation analysis

Verticillium dahliae CFEM Effector VdCR Stabilises the Susceptibility Factor GhAGP31 to Suppress Host Vascular Immunity and Promote Cotton Verticillium Wilt

Plant, Cell &Environment, EarlyView.
ABSTRACT Plant pathogenic fungi secrete a wide array of effector proteins to manipulate host immunity, including those containing CFEM (Common in Fungal Extracellular Membranes) domains. Here, we identified a CFEM domain‐containing effector VdCR from Verticillium dahliae, the causal agent of cotton Verticillium wilt.

Effect of defoliation on patterns of carbon exudation from Agrostis capillaris

, 2004
Grassland ecosystems are important global sinks and sources of atmospheric carbon (C). In this study, we used an in-situ 13CO2 tracer approach to quantify differences in short-term C exudation from defoliated and non-defoliated Agrostis capillaris (L ...

Alterations in plant architecture and physiology allow maize to sustain yield after early defoliation

Agrosystems, Geosciences & Environment
Maize (Zea mays L.) tolerance to early defoliation is shaped by genotype‐specific physiological and morphological responses. Defoliation disrupts the source–sink balance, altering carbon allocation and plant development.

Effects of Defoliation at Different Fertility Stages on Material Accumulation, Physiological Indices and Yield of Cotton

Agriculture
In recent years, severe hailstorms have caused damage to cotton leaves and stalks. In order to identify the effects of cotton leaf damage on its dry matter accumulation, protective enzyme activity and yield in different periods, in this experiment ...

Cotton rotation with single and multispecies cover crops affects yield, quality, and economic outcomes

Agrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.
Abstract Cover crops (CCs) have gained popularity in continuous crop production systems due to their agroecosystem benefits. This study evaluated the effects of nine CC treatments (single or multispecies) and no cover crop (noCC) on cotton (Gossypium hirsutum L.) growth characteristics, production, and economic returns in the Mid‐South United States ...

Minimising sunburn necrosis on Vitis vinifera L. ‘Riesling’ grapes by defoliation, photo- and thermal protection [PDF]

Sunburn on grapes has emerged as an economic concern in recent decades. The phenomenon can be attributed to climatic changes, characterised by elevated air temperatures and intense solar radiation, leading to increased crop failures as well as quality ...

Leaf economics and tissue turnover dynamics in four perennial C4 grasses

Agrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.
Abstract Warm‐season perennial grasses are important components of pasture systems in the United States, yet their functional characteristics and relationships with productive attributes remain poorly understood. This study evaluated tissue flow dynamics and leaf economic traits in four C4 forage grasses: eastern gamagrass (Tripsacum dactyloides (L.) L.

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

Crop, 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 ...
