Experiments to investigate the effect of various thermotherapy and fungicide treatments on the germination of single-budded setts (SBS) of sugarcane are described. Treatment in water at 52OC for 10 minutes significantly increased germination and plant growth. Immersing setts in cold water containing Eria@ (62,5 ppm carbendazim + 31,25 ppm difenoconazole; 0,5 m1 in 1 L) for 10 minutes also impro...

The endophytic fungus strain 0248, isolated from garlic, was identified as Trichoderma brevicompactum based on morphological characteristics and the nucleotide sequences of ITS1-5.8S- ITS2 and tef1. The bioactive compound T2 was isolated from the culture extracts of this fungus by bioactivity-guided fractionation and identified as 4β-acetoxy-12,13- epoxy-Δ(9)-trichothecene (trichodermin) by spe...

The potential of variable angle synchronous spectroscopy (VASS) for fluorescent mixtures resolution was assessed and compared with the rank annihilation method (RAM). For this purpose, a set of excitation-emission matrices from three standard cyclodextrin fluorescence-enhanced solutions of the pesticides aminocarb, carbendazim and coumatetralyl and a mixture of them was obtained. Careful select...

The binding and inhibitory properties of 11 benzimidazoles for bovine brain tubulin were investigated. The effects of the benzimidazoles on the initial rates of microtubule polymerization were determined by a turbidimetric assay. The median inhibitory concentrations (I50) for nocodazole, oxibendazole, parbendazole, mebendazole and fenbendazole ranged from 1.97 . 10(-6) to 6.32 . 10(-6) M. Benom...

A series of novel trifluoromethylcoumarinyl urea derivatives were designed, synthesized, and characterized by ¹H-NMR, 13C-NMR, and HR-ESI-MS. The fluorescence spectra of the target compounds were recorded. The spectra show that most of the title compounds glow green with λmaxem of 500-517 nm, while compounds 5r, 5s, 5u, and 5l (compounds named by authors) glow violet with λmaxem of 381-443 nm. ...

Pesticides residues in aquatic ecosystems are an environmental concern which requires efficient analytical methods. In this study, we proposed a generic method for the quantification of 13 pesticides (azoxystrobin, clomazone, diflufenican, dimethachlor, carbendazim, iprodion, isoproturon, mesosulfuron-methyl, metazachlor, napropamid, quizalofop and thifensulfuron-methyl) in three environmental ...

We estimated the amount of test solution absorbed by each Chromosorb W AW particle (60-80 mesh) using an isotopic technique to quantitate the particle method. 14C-Labeled standard compounds like carbendazim (MBC), 5-O-methylcochliophilin A, sucrose and proline were dissolved in several solvents, and Chromosorb carrier particles were treated with the solution to coat the particle with these test...

The antifungal effect of aqueous extracts of four plant species viz; Azadaracta indica A. Juss., Datura metel L. var. quinquecuspida Torr., Ocimum sanctum L. and Parthenium hysterophorus L. was determined in vitro study. It was found that all the plant extracts at 40% concentration were effective in reducing the mycelial growth of F. oxysporum f. sp. ciceri. Among these plants extracts, A. indi...
