In this study, a bioherbicide was produced by solid-state fermentation (SSF) using Diaporthe sp. Adjuvants were employed in a formulation to enhance the herbicidal activity towards the target (Cucumis sativus). The study was divided into two steps: (1) the fermentation condition for bioherbicide production was assessed; (2) evaluation of different formulations containing palm oil, Tween® 80 and...

Soil degradation is an unavoidable phenomenon that poses a real threat, as it limits soil utility and reduces its resources. Early assessment of can prevent further deterioration. Various parameters microbial activity may be helpful in this evaluation. Therefore, the purpose study was to assess usefulness microbiological (total abundance oligotrophic bacteria filamentous fungi), biochemical (so...

The phytotoxicity of the three major monoterpene constituents of the essential oil from leaves of Artemisia scoparia Waldst. & Kit. (redstem wormwood) was investigated. GC/GC-MS analysis revealed that the essential oil (yield 0.84%) is a complex mixture containing 19 monoterpenes, 7 sesquiterpenes and 15 other compounds--aliphatic alcohols, ketones, aromatic hydrocarbons and esters. The three m...

This study investigated the phytotoxicity of herbicides applied singly or as mixtures to different crops under greenhouse conditions. Growth inhibition of the crops was taken as an indicator of phytotoxicity. Phytotoxicity of mixtures was estimated by calculating EC50 value in toxic units. EC50 (mg/kg soil) of Alachlor, Bromacil and/or Diuron were: 11.37, 4.77, 1.64, respectively, on melon; 0.1...

background: this study investigated the effects of some important meteorological parameters and filler type compounds on phytotoxicity of captan in peach trees in the north of iran. captan is a phthalimide fungicide which has frequently been used in northern regions of iran to control certain plant diseases. this fungicide has caused intense phytotoxicity in peach trees which was first observed...

Chiral 3,3a,5,9b-tetrahydro-2H-furo[3,2-c][2]benzopyrans (TFBs) were synthesized and some of them were found to be herbicidally active against annual paddy weeds through intensive structure–activity relationship studies. These compounds were synthesized from D-glucose, which was used as a natural chiral source. This was the result of a series of studies based on the findings that certain benzyl...

Replacing biosilicon and biocarbon in soil via biochar amendment is a novel approach for soil amelioration and pollution remediation. The unique roles of silicon (Si)-rich biochar in aluminum (Al) phytotoxicity alleviation have not been discovered. In this study, the alleviation of Al phytotoxicity to wheat plants (root tips cell death) by biochars fabricated from rice straw pyrolyzed at 400 an...

The effectiveness of 12 chemical compounds (azoxystrobin, carbendazim, chlorothalonil, fenarimol, folpet, mancozeb, myclobutanil + mancozeb, prochloraz + carbendazim, tebuconazole + triadimefon, tetraconazole + chlorothalonil, tiophanate-methyl, tridemorph + epoxiconazole) in the control of Puccinia horiana was tested on chrysanthemum cv. Fiji Yellow. Additionally, their influence on plant grow...
