Roots induce stronger soil water repellency than leaf waxes

, 2014
Hydrophobic organic compounds in soils, mainly derived from plants, cause soil water repellency (SWR). The relation between such hydrophobic compounds, which we call SWR-markers, and SWR has been rarely known.

Evolutionary trade‐offs between beauvericin production and growth define divergent virulence strategies in Beauveria

Pest Management Science, EarlyView.
Two virulence strategies in Beauveria: a growth strategy characterized by rapid within‐host proliferation, and a toxin strategy involving antimicrobial activity and toxicity to insects Abstract BACKGROUND Pathogen virulence is often attributed to toxin production, yet toxins are metabolically costly and may not universally enhance fitness.

EPICUTICULAR WAXES AND THE ENERGY BALANCE OF SORGHUM [Sorghum bicolor (L.) Moench] [PDF]

, 2019
Epicuticular waxes are hypothesized to enable plants to cope with drought. There is evidence that waxes alter the energy balance of plants through increase in reflectivity of solar radiation and through decrease in conductance of water vapor from the ...

Experimental dissection of phenotypic variation for quantitative disease resistance in canola (Brassica napus) – Leptosphaeria maculans interactions

Pest Management Science, EarlyView.
This graphical abstract illustrates how quantitative resistance to Leptosphaeria maculans in canola is experimentally estimated through multi‐environment replicated trials measuring crown canker severity. Genotype, environment and pathogen sources feed into phenotyping, followed by variance partitioning using mixed models and beta regression to ...

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 ...

Leaf litter decomposition from native and non-native species in a freshwater forested wetland of Chile

Gayana, 2019
Decomposition of leaf litter is a fundamental process for the functioning of forested wetlands. The rapid increment of forest plantations has involved a greater contribution of leaf litter of exotic origin to these ecosystems.

Survival and behavior of Plutella xylostella larvae on cabbage with waxes altered by treatment with Sethyldipropylthiocarbamate.

, 1992
Cabbages (Brassica oleracea L.) treated with S-ethyl dipropylthiocarbamate (EPTC) herbicide had reduced amounts of leaf surface waxes (40.6~o of controls) and reduced densities of leaf surface wax crystallites (20.8~o of controls).

Strain‐specific monitoring of Bacillus amyloliquefaciens AH2 in strawberry fields using a specific molecular marker

Pest Management Science, EarlyView.
A novel strain‐specific TaqMan quantitative polymerase chain reaction assay targeting the hsdM gene was developed to monitor Bacillus amyloliquefaciens AH2 in strawberries, providing a foundational tool to optimize biocontrol management. Abstract BACKGROUND The biocontrol agent Bacillus amyloliquefaciens AH2 is effective against Botrytis cinerea in ...

Assessing the capacity of trees and shrubs species to accumulate of particulate matter (PM10, PM2.5 and PM0.2)

سلامت و محیط, 2019
Background and Objective: Today, the presence and increase of particulate matter is one of the serious factors that threaten human health. In the meantime, trees can accumulate airborne particles by their foliage.

Comparison of nonchemical, organic and synthetic Varroa destructor control strategies in honey bee colonies: effects on parasite load, colony strength and health

Pest Management Science, EarlyView.
Combining intensive drone‐brood removal with brood interruption provided the most effective and consistent seasonal Varroa control. Abstract BACKGROUND Varroa destructor remains the most significant biotic threat to honey bee colonies, and increasing resistance to synthetic acaricides necessitates alternative control strategies.
