Complete floret abortion on sorghum panicles due to sorghum midge (Stenodiplosis sorghicola) infestation was observed just after flowering onset in early August (2008) in fields near Montpellier (France). With the aim of controlling these infestations, mathematical models simulating the biological development of the insect as a function of temperature, which were developed in Texas (USA) and ad...

A study was undertaken to evaluate effectiveness of foliar spray with 33 plant extracts against leaf spot (Tikka) of groundnut caused by Cercospora arachidicola and Cercosporidium personatum. Bavistin and BAU-Biofungicide were included in the experiment as checks and spray of plain water represented control. Almost all treatments gave considerable reduction in disease incidence and increase in ...

The aim of this work was to study the fungal diversity in Paspalum notatum, order determine potential biological control disease-causing pathogens and their effects on growth promotion. Two isolates Cercospora dianellicola were identified from asymptomatic P. notatum leaves, as an endophytic species. possible benefits for host plant remain be analyzed.

Abscisic acid production by Cercospora rosicola Passerini in liquid shake culture was measured with different amino acids in combination and singly as nitrogen sources and with different amounts of thiamine in the media. Production of abscisic acid was highest with aspartic acid-glutamic acid and aspartic acid-glutamic acid-serine mixtures as nitrogen sources. Single amino acids that supported ...

A series of pyrazole carboxamide and isoxazolol pyrazole carboxylate derivatives were designed and synthesized in this study. The structures of the compounds were elucidated based on spectral data (infrared, proton nuclear magnetic resonance and mass spectroscopy). Then, all of the compounds were bioassayed in vitro against four types of phytopathogenic fungi (Alternaria porri, Marssonina coron...

Triphenyltin hydroxide (TPTH) has been used extensively in the Northern Great Plains in recent years for the control of Cercospora leaf spot on sugarbeet. Although mancozeb and, to a lesser extent, the benzimidazole fungicides often are implemented in conjunction with TPTH for optimum leaf spot control, TPTH continues to be the most widely used compound for control of the disease. Eminent (tetr...
