Severity of foliar fungal diseases and soybean defoliation under seeding densities

, 2022
Cultural practices such as adjusting the sowing density of soybeans have contributed significantly to the prevention and management of foliar diseases, through changes caused in plant growth, closure of inter-rows and the penetration rate of pesticides into the crop canopy.

Generation Rather Than Sex Shapes Wing Morphology in Cydalima perspectalis (Lepidoptera, Crambidae): Insights From Geometric Morphometrics and Climate‐Based Projections

Entomologia Experimentalis et Applicata, EarlyView.
An integrated framework combining geometric morphometrics and ecological niche modeling was applied to Cydalima perspectalis to assess intergenerational morphological variation, test sexual dimorphism, and predict future distribution under climate scenarios. Wing shape effectively discriminated between generations but not between sexes.

Effect of adding fungicide to mixtures of triazoles and strobilurins in the control of downy mildew and Asian soybean rust

Pesquisa Agropecuária Tropical, 2019
Fungicides used to control the Asian soybean rust are composed almost entirely of mixtures involving the systemic (triazoles) and meso-systemic (strobilurins) modes of action.

Morphogenic and structural characteristics of guinea grass pastures submitted to three frequencies and two defoliation severities [PDF]

Revista Brasileira de Zootecnia, 2011
It was evaluated the morphogenic and structural characteristics of guinea grass under rotational at three grazing intervals and two defoliation intensities. Grazing intervals corresponded to the time needed by the forage canopy to reach 90, 95 or 100% of incident light interception during regrowth and they were evaluated combined to two defoliation ...

Fly me to the canopy: Diptera communities in oak forest crowns as bioindicators of stand decline

Insect Conservation and Diversity, EarlyView.
Diptera diversity: Oak decline increases the overall Diptera diversity, particularly in saproxylic and floricolous guilds, likely due to more open canopies and greater deadwood and floral resource availability. Family responses: Dolichopodidae, Empididae, Hybotidae and Anthomyiidae thrive in declining stands, whereas Mycetophilidae and other fungus ...

Effects of defoliation by the pine processionary moth Thaumetopoea pityocampa on biomass growth of young stands of Pinus pinaster in northern Portugal

iForest - Biogeosciences and Forestry, 2010
Biomass growth models for 13-year-old maritime pine tree stands (Pinus pinaster Ait.) in the north-eastern Portugal were developed and used to analyse the effects of the defoliation by the pine processionary moth, Thaumetopoea pityocampa (Den. & Schiff.)

Genome assembly of Elcysma westwoodi provides insights into host‐plant cyanogenic glucoside detoxification and chemical defence gene evolution

Insect Molecular Biology, EarlyView.
A chromosome‐level genome of Elcysma westwoodi was assembled. The genome encodes 272 detoxification‐related genes. A single‐copy bCAS was retained for cyanide detoxification. CYP405A and CYP332A were recruited into cyanogenic defence evolution. UGT33A retained a conserved GT‐B fold and catalytic domains.

Chemical control of the soybean target spot (Corynespora cassiicola) in the cerrado of tocantins - Brazil

Journal of Bioenergy and Food Science, 2017
The fungus Corynespora cassiicola (Berk. & M.A. Curtis), the causal agent of the target spot in soybean, have occurred frequently in the North Central region of Brazil and may, under high temperature and high humidity conditions, cause serious damage to ...

Staurosporine Targets Mitochondrial Regulator VdAtuA3 to Disrupt Mitochondrial Homeostasis to Control Verticillium Wilt

Plant Biotechnology Journal, EarlyView.
ABSTRACT Mitochondria serve as cellular powerhouses that generate ATP via electron transport chain complexes and orchestrate metabolism‐apoptosis cross‐talk, yet genes maintaining mitochondrial homeostasis remain underexplored as antifungal targets. In this study, a previously uncharacterised protein VdAtuA3 was identified as a novel interactor with ...

Carbon partitioning between shoot organs following early leaf removal

BIO Web of Conferences, 2019
In grapevines, basal leaf removal at bloom often induces a reduction of fruit set. The effect is related to a reduction in carbon availability for different plant organs competing for photosynthates.
