The chemical management of the black leaf streak disease in banana caused by Mycosphaerella fijiensis (Morelet) requires numerous applications of fungicides per year. However this has led to fungicide resistance in the field. The present study evaluated the activities of six fungicides against the mycelial growth by determination of EC50 values of strains collected from fields with different fu...

Seed dressing, i.e., the treatment of crop seeds with insecticides and/or fungicides, aiming to protect seeds from pests and diseases, is widely used in conventional agriculture. During the growing season, those crop fields often receive additional broadband herbicide applications. However, despite this broad utilization, very little is known on potential side effects or interactions between th...

Maize is a socioeconomically important crop in many countries. Recently, a high incidence of stalk rot disease has been reported in several maize fields in Gangwon province. In this report, we show that maize stalk rot is associated with the fungal pathogens Fusarium subglutinans and F. temperatum. Since no fungicides are available to control these pathogens on maize plants, we selected six fun...

Cover: Scanning electron micrograph of 7-day-old colony of powdery mildew (Blumeria graminis f.sp. tritici) on a wheat leaf. Insert shows a 2-day-old colony at higher magnification. Although the sensitivity of mildew populations towards certain fungicides has changed considerably over the years, implementation of resistance management strategies has helped to sustain an overall satisfactory deg...

In order to study the contamination of Aspergillus flavus and aflatoxin production in pistachio cultivars in the Semnan province, eight cultivars of pistachio were collected from major pistachio growing areas. Using the serial dilution method, ground pistachio kernels were inoculated on plates containing AFPA medium and incubated at 28° C. This experiment was performed using three replications ...

Stored product fungi cause severe degradation of food items during storage and also cause health hazards by secreting various mycotoxins. Due to negative concerns on health and environment, many synthetic fungicides have been removed through the Food Quality Protection Act in the United States which hinted the exploration of plant products as safe fungicides. Different in vitro studies have dem...

In 1930 the writer (7Y presented the results of early experiments on the control of barley covered smut (Ustilago hordei (Pers.) Kell, and Sw.) with dust fungicides, together with a rather comprehensive review of the pertinent literature on the subject up to that time. The development since then of new fungicidal dusts, some of which were effective in controlling barley stripe (Helminthosporium...
