Dispersal and genetic variability of Sonchus oleraceus L. in relation to its resistance to ALS-inhibiting herbicides. [PDF]

, 2011
The work described in this thesis investigates the existence and level of acetolactate synthase (ALS)-inhibiting herbicide resistance in Sonchus oleraceus in Australia. It further discusses the sensitivity of different S.

Logistic Analysis for Monitoring and Assessing Herbicide Efficacy

, 1992
Two relatively new methods for analyzing herbicide efficacy data are described. Weighted multiple regression using the logit transformation for plant mortality data is illustrated and compared with the more accurate maximum likelihood logistic regression

Neonicotinoid seed treatments do not consistently reduce insect feeding damage nor increase yields in Maryland soy

Agricultural and Forest Entomology, EarlyView.
We compared soybean plants from untreated and treated seeds across 4 sites and 3 years in Maryland. Neonicotinoid seed treatments (NST) provided little reduction in insect stippling damage and no reduction in chewing damage. NST did not result in increased plant biomass or bean yield. Abstract The use of neonicotinoid insecticides in seed treatments in

Pro‐environment behaviors, invasive plant management, and the gap between motivations for behavioral intention and action

Conservation Science and Practice, EarlyView.
Invasive plant species pose significant challenges to natural resources and communities around the world. However, invasive plant management may require different motivations than other pro‐environmental behaviors because mitigation of invasive plants often comes at high individual cost, has limited effectiveness when undertaken in isolation, and ...

Effective control of loose silky-bent (Apera spica-venti (L.) P.B.) in winter cereals using highly efficacious herbicide treatments. Results of comparative trials in the federal states Brandenburg, Hessen, Saxony, Saxony-Anhalt and Thuringia from 2001 to 2011

Julius-Kühn-Archiv, 2012
In recent years, an increasing occurrence of resistance to Apera spica-venti, especially to ALS inhibitors and partially to ACCase inhibitors has been reported for the new federal states, too.

Efficacy and selectivity of post-emergent application of flumioxazin and oxyfluorfen in sunflower

Plant, Soil and Environment, 2011
Four efficacy and selectivity small plot field trials were carried out in four sunflower hybrids at two localities in Middle Bohemia during 2008 and 2009 with herbicides containing the active ingredients flumioxazin and fluorochloridone.

Biology of the Gall Midge Spanolepis selloanae (Diptera, Cecidomyiidae), a Candidate Biological Control Agent of the Invasive Grass Cortaderia selloana

Entomologia Experimentalis et Applicata, EarlyView.
Spanolepis selloanae (Diptera, Cecidomyiidae) infests Cortaderia selloana (pampas grass). It lays eggs in the spikelets, where larvae feed on female parts. The high prevalence of the midge and its combined impact in seed production, condition and viability strongly reduces the reproductive output of C. selloana.

Biodiversity versus transgenic sugar beet : the one Euro question [PDF]

, 2002
The decision whether to release transgenic crops in the EU is one subject to flexibility, uncertainty and irreversibility. The case of herbicide tolerant sugar beet is analysed.

Smart double‐screening system of propagating male‐sterile lines for maize hybrid seed production

Journal of Integrative Plant Biology, EarlyView.
The Seed and Seedling Marker Method double‐screening system for maize hybrid seed production integrates Ms45‐mediated fertility restoration, Mn1/Sh1‐RNAi‐based seed selection, and Lc‐based seedling selection. It thus enables efficient, high‐purity propagation of male‐sterile lines by combining fertility maintenance with sequential visual selection at ...
