Hairy crabgrass (Digitaria sanguinalis (L.) Scop.) is a troublesome weed in most agricultural crops worldwide. Considerable efforts are made to limit the invasiveness and impact of crabgrass on crop productivity, including evaluation of fungi as biocontrol agents (3). In September 2005, a severe
Maize (Zea mays) has become an important crop in Poland with a constant increase in crop acreage since the 1990s. In 2007, maize plants with characteristic leaf mosaic were observed in two locations in the Wielkopolska Region near Poznań and Krotoszyn. Ninety-two samples from plants showing leaf
In a survey of fungi and mycotoxin conterminating acha (Digitaria exilis Stapf) in Plateau State of Nigeria, 96 fungal isolates were made. Screening of the fungi isolates for their mycotoxin-producing potentials showed that Aspergillus quadrilineatus (Thom and Raper) produced some of the most toxic
A carboxylic ester group was introduced to three series of isoindolinedione substituted benzoxazinone derivatives. Some of these analogues exhibited good herbicidal activities, and the injury symptoms against weeds included leaf cupping, crinkling, bronzing, and necrosis, typical of protox inhibitor
Drechslera gigantea, a potential mycoherbicide of grass weeds, was isolated in Florida from naturally infected large crabgrass (Digitaria sanguinalis); it produces phytotoxic metabolites in liquid culture. The main metabolite was identified by spectroscopic methods and optical properties as
