Drought and surface‐level solar radiation predict the severity of outbreaks of a widespread defoliating insect [PDF]

Ecosphere, 2018
AbstractDefoliating insects are a major factor impacting tree growth in temperate and boreal forests, but the effects of climate change on the severity and frequency of outbreaks of these insects are not well understood. Dendrochronological reconstruction of forest tent caterpillar (Malacosoma disstria) outbreaks on trembling aspen (Populus tremuloides)

Controlled incubation, leachate, and pot assays of shrimp shell‐based compost for suppressing Verticillium dahliae in olive

Pest Management Science, EarlyView.
Shrimp shell compost suppresses Verticillium dahliae microsclerotia, enhances chitinase activity, lowers olive wilt severity and improves plant recovery under controlled conditions. Abstract BACKGROUND Verticillium wilt of olive (Olea europaea L.), caused by Verticillium dahliae Kleb., is difficult to manage because long‐lived microsclerotia persist in

MORTALITY IN IMMATURE BALSAM FIR FOLLOWING SEVERE BUDWORM DEFOLIATION

The Forestry Chronicle, 1960
In northwestern New Brunswick mortality is being followed in a 40- to 50-year-old stand of fir and spruce which was subjected to severe spruce budworm defoliation from 1951 to 1957. This paper reports some early findings by diameter and dominance classes.

Defoliation of sweet corn plants under irrigation depths and its impact on gas exchange

Revista Brasileira de Engenharia Agrícola e Ambiental
The objective of this work was to evaluate leaf gas exchanges of sweet corn as a function of defoliation when submitted to different irrigation depths. The experimental design was randomized blocks in split-plot scheme, with four irrigation depths in the

Temporal progress of teak rust in a tropical area of Tocantins State, Brazil [PDF]

Acta Amazonica, 2017
Rust, caused by Olivea neotectonae, stands out as the main teak disease, causing premature defoliation regardless of the tree’s growth stage. In this study, we aimed to assess the temporal progress of rust in adult teak plants in southern Tocantins State
