Pest categorisation of Blissus insularis. [PDF]

EFSA J, 2023
Abstract The EFSA Panel on Plant Health performed a pest categorisation of Blissus insularis (Hemiptera: Heteroptera: Blissidae) for the European Union (EU) territory. B. insularis, known in the US as the southern chinch bug, primarily feeds on St. Augustine grass (Stenotaphrum secundatum, Poaceae, subfamily Panicoideae).

Growth and Development of Digitaria insularis Biotypes Susceptible and Resistant to Glyphosate [PDF]

Planta Daninha, 2017
The study aimed to evaluate the growth and development of biotypes of Digitaria insularis susceptible and resistant to glyphosate. Samples of biotypes were collected in Western Paraná in Cascavel, one susceptible (24o57'29.06" S and 53o30'23.73" W) and ...

Species-specific effects of post-application relative humidity on glufosinate efficacy and absorption in Bassia scoparia and Chenopodium album. [PDF]

Pest Manag Sci
Glufosinate efficacy and absorption are mediated by post‐application relative humidity duration in Bassia scoparia and Chenopodium album, but the effects are species‐specific. Abstract Background In the semi‐arid United States, where relative humidity (RH) in summer ranges from 25% to 35%, suboptimal glufosinate efficacy is a recurrent issue, but ...

Genetic diversity and population structure of ALS-resistant Amaranthus hybridus across Brazil's primary soybean-growing regions. [PDF]

Pest Manag Sci
We identified two distinct target‐site mutations, Asp‐376‐Glu and Trp‐574‐Leu, that confer resistance to acetolactate synthase inhibitors in Amaranthus hybridus populations across Brazil's soybean‐growing regions. These findings suggest multiple independent origins of resistance, with its spread primarily driven by local herbicide selection pressure ...

Foliar structural differences between glyphosate-resistant and glyphosate-susceptible biotypes of Digitaria insularis (L.) Fedde [PDF]

Revista Ceres, 2023
Digitaria insularis (L.) Fedde stands out for its resistance to glyphosate and this characteristic may have a relationship with structural alterations. In such context, this research aimed at the characterization of the foliar anatomical structure of two

Target-site mutations Ile1781Leu and Ile2041Asn in the ACCase2 gene confer resistance to fluazifop-p-butyl and pinoxaden herbicides in a johnsongrass accession from Arkansas, USA. [PDF]

Plant Direct
Abstract Johnsongrass [Sorghum halepense (L.) Pers.] is a troublesome weed species in different agricultural and non‐agricultural areas. Because of its biology, reproductive system, and seed production, effective management is challenging. An accession with low susceptibility to the acetyl‐CoA carboxylase (ACCase)‐inhibiting herbicides fluazifop‐p ...
