Effect of defoliation interval and height on the growth and quality of Arachis pintoi cv. Amarillo [PDF]

, 2007
The effect of defoliation on Amarillo (Arachis pintoi cv. Amarillo) was studied in a glasshouse and in mixed swards with 2 tropical grasses. In the glasshouse, Amarillo plants grown in pots were subjected to a 30/20°C or 25/15°C temperature regime and to

An extinction‐emergency metacollection: Maximising future recovery options for Rhodomyrtus psidioides (Myrtaceae), threatened by Myrtle Rust

PLANTS, PEOPLE, PLANET, EarlyView.
A challenge for wild plant conservation is the rising incidence of plant pathogens that are difficult to interdict, contain and manage. Invasive, fast‐moving, broad‐spectrum pathogens impose societal costs through losses of intrinsically valuable wild biodiversity, ecosystem function, current and potential genetic and biological assets, culturally ...

Consequences of repeated defoliation on belowground bud banks of Carex brevicuspis (Cyperaceae) in the Dongting Lake wetlands, China

Frontiers in Plant Science, 2016
Despite the predominant role of bud banks in the regeneration of clonal macrophyte populations, few studies have examined the way in which clonal macrophytes adjust the demographic features of bud banks to regulate population dynamics in response to ...

The functional role of ants in no‐till cropping systems

Pest Management Science, EarlyView.
Ants provide valuable ecosystem services in tropical agriculture, but their roles in temperate row crops remain poorly understood. Conservation practices such as no‐till farming and cover cropping support ant communities that contribute to pest suppression, weed seed removal, and soil quality, which can increase crop productivity.

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

Absorption and translocation of 14C‐propiconazole associated with two adjuvants in young coffee plants

Pest Management Science, EarlyView.
Experimental workflow evaluating 14C‐propiconazole absorption and translocation in Coffea arabica with two biodegradable adjuvants, quantified at six post‐application time points using radioscanner and liquid scintillation spectrometry. Abstract BACKGROUND This study evaluated the absorption, translocation and distribution of 14C‐propiconazole applied ...

Defoliation of Oaks [PDF]

Nature, 1922
A REFERENCE to the defoliation of oaks, particularly on the borders of Surrey and Hampshire, by the larvae of Tortrix viridana, was made in NATURE on June 10. It concludes with the remark that the effect of the defoliation is to check “the growth of the trees to some extent for the time being, but is rarely more serious.”

Critical impact of defoliation on garlic yield during key developmental stages [PDF]

Pesquisa Agropecuária Brasileira
The objective of this work was to evaluate the effect of defoliation levels at different growth stages of garlic plants on total and marketable yields. The experiments were conducted during two crop seasons, when five dates (30, 60, 90, 110, and 130 days

Environmental Stress Effects on Vigor, Mortality, and Growth in Northern Hardwood Forests Along a Pollution-Climate Gradient [PDF]

, 1998
Concern exists over the effects of interacting environmental stresses on the ecological integrity of temperate forests. Coincidence of sensitivity to drought, increasing occurrence of defoliation, and elevated pollutant deposition has produced ...

Persistence of seed‐applied pesticides in soybeans: environmental influences and implications for crop protection

Pest Management Science, EarlyView.
Early soybean planting in cool, wet soils slows emergence and results in about half the insecticide and fungicide concentrations at vegetative emergence compared with standard planting, where faster emergence maintains roughly double the pesticide concentrations, yet pesticide persistence remains similar across both planting dates.
