fungicidal efficiency of iranian made benzalkonium chloride named akhgar, afshang and hamoon were evaluated on pure culture species of aspergillus nijer, candida ablicans and mucour according to the standard method no. 2442 issued by the institute of standards and industrial research of iran, from october 1993 to march 1994. suspensions were prepared in a way that each cubic centimeter having 3...

The management of common apple diseases relies heavily on effective fungicide applications. However, the evolution of fungicide resistance by many pathogens has resulted in management failures and significant economic losses. With time and the increasing development of fungicide resistance in apple scab, and possibly bitter rot, more and more apple growers rely on Captan, an older fungicide, be...

A simple method to determine the toxicity of fungicides on male gametophyte in Brassica campestris subsp. oleiferae is described. The calculation of fungicide concentration used in the test is derived from doses used in field application. The expression of regression curves and calculation of regression equations require the logarithmic transformation of fungicide concentration. The range of th...

Study Examines Epigenetic Effects of Fungicide Exposure A mother’s environmental exposure can result in transgenerational effects that are inherited through successive generations, even in the absence of exposure of the offspring. A new proof-of-principle study reports that great-grandchildren of rats exposed to the common fungicide vinclozolin showed a more profound behavioral and neurodevelop...

Pseudomonas fluorescens strain LRB3W1 inhibited the mycelial growth of Fusarium oxysporum f. sp. lycopersici and suppressed the Fusarium wilt of tomato. The chemical fungicide, benomyl, did not suppress the disease incidence at low concentrations. However, the disease incidence was decreased by the combined application of benomyl at low concentrations with strain LRB3W1. Combined application of...

Copper-based fungicides can be effectively digested by treatment with a mixture of concentrated sulfuric and nitric acid in exactly 15 minutes for the rapid determination via copper using flame atomic absorption spectrometry (AAS). Under optimum conditions, the results of copper fungicide analysis were consistent to those obtained by the AOAC’s recommended method. Recovery values ranged from 98...

introduction: biofertilizers have been identified as alternative to chemical fertilizers to increase soil fertility and crop production in sustainable farming systems. one of the most useful kind of biofertilizers include plant growth promoting rhizobacteria (pgpr). azospirillum is an associative rhizobacteria which can be very useful for plants such as wheat. it can help plant by fixing nitrog...

almond red leaf blotch is the most important fungal disease that is caused by the fungus polystigma amygdalinum. symptoms depending on the cultivar almond trees can be seen almost all year. in this study the effect of 5 fungicides (copper oxychloride  2000 µg/ml, bordofix 2000 µg/ml, mancozeb 200 µg/ml, bordo compound 10000 µg/ml, triforin 300 µg/ml with rep.control) was examined in a randomize...

background: antifungal drug resistance and few numbers of available drugs limit therapeutic options against fungal infections. the present study was designed to discover new antifungal drugs.   m aterials and methods: this study was carried out in two separate steps, that is, in silico lead identification and in vitro assaying of antifungal potential. a structural data file of a ternary complex...
