Tolerance of cowpea cultivars to pre-emergence application of sulfentrazone

open access: yesRevista Ceres, 2021
Improved methods of weed control are required to support expansion of large-scale cowpea cultivation in mid-west Brazil. With the aim of testing our hypothesis that the tolerance of cowpea cultivars to sulfentrazone is dose- and genotype-dependent, we ...

Residual herbicides increase the period prior to interference in soybean cultivars [PDF]

open access: yesPlanta Daninha, 2020
Background: The pre-emergence herbicides diclosulam and flumioxazin are used to weed control in soybean. We hypothesized management of the new emergence of weeds in the early development stages of the soybean could alter the periods of interference ...

Neutralizing antibody vaccine for pandemic and pre-emergent coronaviruses [PDF]

open access: yesNature, 2021
Betacoronaviruses (betaCoVs) caused the severe acute respiratory syndrome (SARS) and Middle East Respiratory Syndrome (MERS) outbreaks, and the SARS-CoV-2 pandemic1–4. Vaccines that elicit protective immunity against SARS-CoV-2 and betaCoVs circulating in animals have the potential to prevent future betaCoV pandemics.

HELIOSEISMOLOGY OF PRE-EMERGING ACTIVE REGIONS. III. STATISTICAL ANALYSIS [PDF]

open access: yesThe Astrophysical Journal, 2014
The subsurface properties of active regions prior to their appearance at the solar surface may shed light on the process of active region formation. Helioseismic holography has been applied to samples taken from two populations of regions on the Sun (pre-emergence and without emergence), each sample having over 100 members, that were selected to ...

Dactyloctenium aegyptium (L.) Willd. (Poaceae) Differentially Responds to Pre- and Post-Emergence Herbicides through Micro-Structural Alterations

open access: yesAgriculture, 2022
Herbicides are widely used to kill weeds and increase crop production all over the world. Nevertheless, some weeds show certain structural modifications in response to herbicide application that impart mostly partial or sometimes complete tolerance to ...

Chemical Control of Morning Glory Species in Sugarcane Harvested in the Dry and Semi-Wet Seasons1 [PDF]

open access: yesPlanta Daninha, 2016
The control of morning glory (Ipomoea spp. and Merremia aegyptia) was evaluated in five commercial sugarcane-production fields receiving applications of the herbicides sulfentrazone (0.9 kg ha-1), amicarbazone (1.4 kg ha-1), imazapic (0.147 kg ha-1), and
