Manejo de rebrotes de Digitaria insularis no plantio direto de milho Management of Digitaria insularis sprouts under no-till corn cultivation [PDF]

Planta Daninha, 2009
Com a dessecação da vegetação espontânea, nem sempre se consegue obter controle total das espécies daninhas, o que leva à perenização e ao aumento da importância daquelas selecionadas.

Population genomics of Digitaria insularis from soybean areas in Brazil. [PDF]

Pest Manag Sci, 2021
AbstractBACKGROUNDDigitaria insularis is a weed species that has gained considerable importance in Brazil's soybean production areas that rely on glyphosate‐resistant cultivars. Herbicide‐resistant weed populations of this species have been reported in many regions in Brazil, first in the south, followed by later reports in the north.

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).

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 ...
