Calibrating the Severity of Forest Defoliation by Pine Processionary Moth with Landsat and UAV Imagery [PDF]
Sensors, 2018 The pine processionary moth (Thaumetopoea pityocampa Dennis and Schiff.), one of the major defoliating insects in Mediterranean forests, has become an increasing threat to the forest health of the region over the past two decades. After a recent outbreak

Defoliation Dynamics in Kikuyugrass Pastures Subjected to Intensities of Defoliation
Agronomy, 2020 Some recent papers have recommended moderate intensities of defoliation in order to maximize herbage intake at different time-scales. Most of them, however, did not assess the grazing dynamics of individual tillers during the stocking period.

Detection of Annual Spruce Budworm Defoliation and Severity Classification Using Landsat Imagery [PDF]
Forests, 2018 Spruce budworm (SBW) is the most destructive forest pest in eastern forests of North America. Mapping annual current-year SBW defoliation is challenging because of the large landscape scale of infestations, high temporal/spatial variability, and the short period of time when detection is possible.

Effect of Severity of Defoliation on the Viability of Reproductive and Vegetative Axillary Buds ofTrifolium repensL. [PDF]
Annals of Botany, 1996 This glasshouse experiment was performed to assess the effects of a range of constant defoliation regimes applied to cuttings of a single large-leaved genotype ofTrifolium repensL. on the viability of its axillary buds. Plants were established to comprise a single main stolon (axillary branches were removed) and defoliation treatments were applied by ...

Relationship between soybean plant defoliation and Asian soybean rust severity [PDF]
Summa Phytopathologica, 2019 ABSTRACT 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 between defoliation and severity, defoliation and grain yield, and grain yield and rust ...

Australian Journal of Grape and Wine Research, 2016 Background and Aims: Early defoliation has been proposed as a tool to reduce bunch susceptibility to fungal infections through a reduction in bunch compactness. This research aims to determine the desired level of defoliation producing looser bunches and to investigate the impact of the application of early defoliation on Pinot Noir vines under cool ...
