  A field experiment was conducted at Rasht, in 2014, to investigate controlling weeds in native Hashemi cultivar paddy fields by different methods of herbicide applications and inoculated with Azotobacter chroococcum. The factorial experiment based on a randomized complete block design with three replicates was performed. Factors were Azotobacter application with two levels (inoculation with or without Azotobacter chroococcum) and weed management regimes with six levels (pretilachlor plus a supplementary hand weeding, bensulfuron methyl plus a supplementary hand weeding, and pretilachlor + bensulfuron methyl plus a supplementary hand weeding, hand weeding during rice growing period + no herbicide, un-weeded during rice growing period + no herbicide). Results indicated that paddy rice yield was significantly increased by 16% after Azotobacter chroococcum inoculation. Rice paddy yield was significantly reduced in un-weeded plots compared to hand weeded and herbicide treated plots. ANOVA also revealed that there was no interaction effect between Azotobacter chroococcum applications and weed management regimes on paddy and biological yields, indicating that the herbicides had no adverse effect on Azotobacter efficiency in promoting growth and paddy yield of rice. Weed dry weight was reduced by 88, 91, 92, and 94 percentages in weeded plot and plots treated with pretilachlor, bensulfuron methyl, and pretilachlor + bensulfuron methyl, respectively, compared to un-weeded plots. Azotobacter chroococcum inoculation had no significant effect on weed biomass. Overall, the result of this experiment confirmed the feasibility of chemical weed control in paddy fields inoculated with Azotobacter chroococcum. Manuscript profile

  Micro algaes have a major role in food chains and aquatic ecosystems. Among the mono cellular algaes in the paddy fields which locted in Mazandaran state, Chlorella vulgaris is an important species in Chlorophyta phylum. Influence of herbicides as the most serious particle of pesticides on the algaes is very considerable. Thererfore this study is performed in orther to determination effect of pertilachlor on the some properties of Chlorella vulgaris. Nine treatments (0, 20, 30, 40, 50, 75, 100, 150 and 300 mg herbicide per 1 liter) prepared in one litter bottle, then 100 cc algae solution and stock culture was added, next this system aerated. Treatments with three replications during 24, 48, 72 and 96 hours were investigated. After treating, effect of pretilachlor on the desity, chlorophyll a concentration, activity of catalase, peroxidase, ascorbat peroxidase, polyphenoloxidase enzymes and lipidic peroxidation were examined. Herbicide increasing at the all times resulted in significant reduction about cellular density (p < 0.0001). Maximum and minimum cellular density was measured in the control (without herbicide) and 300 mg pertilachlor treatment, respectively. The less Chl a consentration was obsereved in the most dose herbicide. Activity rate of quadruple enzymes in long term (9 days), indicated significant loss with increasing herbicide dose. Also lipidic peroxidation in all treatments was more relative to control. In this study was shown enzymes activity in high pretilachlor concentrations was not enough that can prevent the reactive oxygen species and this material was targeted by herbicide. Manuscript profile
