Generating Gerbera Foliar Nutrient Interpretation Ranges with a Meta-analysis Sufficiency Range Approach

open access: yesHortScience
Foliar tissue analysis is an important method for diagnosing nutritional problems in greenhouse crops. Currently, gerbera foliar tissue standards are based on small sample populations and limited rate studies. This study expands prior work and presents a

Chlorantraniliprole: bioactivation in coffee seedlings and control of resistant Leucoptera coffeella populations

open access: yesPest Management Science, EarlyView.
Chlorantraniliprole enhanced growth and biomass in coffee seedlings infested by susceptible Leucoptera coffeella, while resistant populations limited its insecticidal performance. These findings emphasize both the bioactivator potential of chlorantraniliprole and the challenges of managing resistance in coffee leaf miner control.

Systematic Foliar Morphology of Phyllanthoideae (Euphorbiaceae). II. Phenetic Analysis

open access: yesAnnals of the Missouri Botanical Garden, 1986
Cladistic analysis of 43 foliar characters was used to explore the phylogeny of genera in Phyllanthoideae and to test the systematic value of foliar morphology. Character polarities were assessed by outgroup analysis treating other subfamilies of Euphorbiaceae and primitive genera in Flacourtiaceae as outgroups.

Integrating bioassays and transcriptomics to detect neonicotinoid resistance in Australian Bemisia tabaci MEAM1

open access: yesPest Management Science, EarlyView.
The Bemisia tabaci MEAM1 strain GR15‐1R shows partial resistance to neonicotinoids (bottom), which correlates with an increased expression of the P450 gene CYP6CM1 compared to the insecticide‐susceptible strain SU07‐1 (top). Abstract BACKGROUND Bemisia tabaci MEAM1 is a highly invasive and polyphagous pest species of agricultural and horticultural ...

Epidemiological drivers of turnip yellows virus and its vector Myzus persicae in Australian canola (Brassica napus) systems: a 3‐year study of commercial crops and noncrop vegetation

open access: yesPest Management Science, EarlyView.
A 3‐year study across southern Australia aimed to characterize drivers of infection in the Myzus persicae–turnip yellows virus–Brassica napus pathosystem. Identification of key reservoir hosts and the strong association between earlier sowing and increased disease incidence highlight opportunities for targeted weed management, strategic sowing ...

Ineffectiveness of foliar nutrient sprays on cotton lint yield after riverine flooding

open access: yes
Irrigated Australian cotton (Gossypium hirsutum L.) is primarily produced on Vertosols, which are susceptible to waterlogging due to their highwater retention capacity and poor drainage.
