Dose-response studies of some herbicides on Echinochloa spp. in Japanese paddy fields

response of rice and barnyardgrass (echinochloa crus-galli) to rate and time of application of some paddy herbicides

this study was carried out in 2008 and 2012 in rice research institute of iran (rasht) in order to study the response of barnyardgrass and rice to oxadiargyl (oxa), butachlor (buta) and thiobencarb (tb) herbicides. treatments included herbicide doses in six levels up to three times the recommended rate, and time of application in two levels before transplanting (bt), and after transplanting (at...

Determination of Dose-Equivalent Response of A Typical Diamond Microdosimeter in Space Radiation Fields

Introduction: Microdosimeters are helpful for dose equivalent measurement in unknown radiation fields. The favorable physical and mechanical properties of the detector-grade chemical vapor deposition diamond materials have made the diamond microdosimeters suitable candidate for radioprotection applications in space. The purpose of this work is the investigation of the dose equivalent response o...

residual phytotoxic effect of some paddy herbicides on the growth of cress and lettuce

one of the crucial issues before the second cropping is having enough knowledge about the residue effect of first crop herbicides on second crops. this experiment was conducted to investigate the possible inhibitory effect of some selective paddy herbicides residues to second cropping. experimental factors were included common paddy herbicides (thiobencarb, butachlor, oxadiargyl, bensulfuronmet...
