Crop protection in organic agriculture - a simple matter? [PDF]

open access: yes, 2002
This report was presented at the UK Organic Research 2002 Conference. Crop protection strategies in organic agriculture and horticulture aim to prevent pest, disease and weed problems through optimisation of the cropping system as a whole.

From Reactive to Proactive Volatility Modeling With Hemisphere Neural Networks

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT We revisit maximum likelihood estimation (MLE) for macroeconomic density forecasting through a novel neural network architecture with dedicated mean and variance hemispheres. Our architecture features several key ingredients making MLE work in this context.

Compound Hot‐Dry Days (CHDDs) and Their Implications on Maize Yields in the Free State Province, South Africa

open access: yesInternational Journal of Climatology, EarlyView.
Compound hot‐dry events occurring during the maize growing period are increasing significantly (p < 0.05) with time, with the median values ranging from 93 to 120 days. El Niño Southern Oscillation (ENSO) influences the variability of compound hot‐dry events with high significance (p < 0.05) positive Pearson correlation.

Regulatory mechanisms of reproduction in locusts and grasshoppers

open access: yesNew Plant Protection, EarlyView.
Regulatory networks composed of numerous coding and noncoding genes play crucial roles in the reproduction of locusts and grasshoppers. This review integrates mechanistic advances in reproductive regulation, highlighting environmentally adaptive pathways and providing prospective targets for eco‐friendly pesticides.

Defense heterosis as a novel plant protection strategy: From theory to breeding practice

open access: yesNew Plant Protection, EarlyView.
Defense heterosis, the enhanced disease resistance of hybrids compared to their parents, has evolved from early observations of hybrid vigor to a novel research concept. Advances are now clarifying its diverse genetic and molecular mechanisms across various plant–pathogen interactions.

Hemophilia A: An Ideal Disease for Prenatal Therapy

open access: yesPrenatal Diagnosis, EarlyView.
ABSTRACT Hemophilia A (HA) is the most common inherited coagulation defect. Current state‐of‐the‐art treatment consists of frequent administration of prophylactic infusions of coagulation factor VIII (FVIII) protein or bispecific antibodies that replace the cofactor function of FVIIIa to maintain hemostasis. However, these treatments are far from ideal,

Detecting and attributing climate change effects on vegetation: Australia as a test case

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Climate change is contributing to vegetation changes that threaten life support systems. Yet, inherent climatic variability and past and present human actions—such as clearing, burning and grazing regimes—also alter vegetation and complicate understanding of vegetation change. Australian ecosystems exemplify such complexity.

Towards an evidence‐based and research‐driven restoration strategy for Britain's temperate rainforests

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Woodlands globally are threatened by environmental change and biodiversity loss. Temperate rainforests are an ecologically rich ecosystem found in wet regions of the temperate zone, and Britain has the potential for major temperate rainforest coverage in its nature‐depleted landscape.

Fungal diseases on tomato plant under greenhouse condition

open access: yesEuropean Journal of Biological Research, 2017
The cultivation of crops in the greenhouse is the most intensive form of horticultural production. Greenhouse climatic conditions provide an ideal condition for the development of many foliar, stem and soil-borne plant diseases.
