In this procedure, infected explants were regenerated on MS medium containing ribavirin at concentrations of 10, 20 and 30 mg/l for 20 and 40 days, followed by a thermotherapy treatment for 30 days at 38 °C for 16 hours and 22 °C for 8 hours per day. The complex of rose viruses (ArMV and PNRSV) were effectively eradicated from regenerated rose plantlets as verified by doubleantibody sandwich enzymelinked immunosorbent assay (DAS-ELISA). Thermotherapy alongside with chemotherapy (containing 30 mg/l per one month) during the period of four weeks was the best treatment for plantlet regeneration and virus elimination. The virus elimination efficiency from ArMV, PNRSV and ArMV + PNRSV infected plants were determined as 63.33%, 90.09% and 85.18%, respectively. A detailed procedure for elimination of mixed viruses is described.","PeriodicalId":15396,"journal":{"name":"Journal of Crop Protection","volume":"5 1","pages":"497-506"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67685035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To characterize 16SrII group phytoplasmas associated with this disease, symptomatic and asymptomatic plants were collected during 2013-2015 and subjected to direct and nested polymerase chain reaction (PCR) using P1/P7, R16mF2/R16mR2 and R16F2n/R16R2. PCR amplicons of ~1.8, ~1.4 and ~1.25 kb respectively, were obtained only from all symptomatic plants. Restriction fragment length polymorphism (RFLP) analysis of R16F2n/R2 amplicons showed that the phytoplasma associated with AWB disease were members of 16SrII group subgroups 16SrII-D and -C. Blast analysis of these amplicon sequences and sequence homology of collected strains and strain sequences retrived from GenBank (AWB strains Chahgeer, Juyom and Bushehr) confirmed that AWB phytoplasmas collected from Bafg, Ardakan, Bahabad and Herat (Yazd province), Nikshahr (Sistan-Baluchestan), Bam, Zarand, Jiroft (Kerman province), Bushehr (Bushehr province), Tabas (South Khorasan province), Jowkar (Hamedan province) and Zardenjan (Esfahan province) cluster with phytoplasma strains enclosed in the 16SrII-D subgroup, while AWB strains from Chahgeer (Yazd province) and Juyom (Fars province) cluster with phytoplasma strains in the 16SrII-C subgroup. Based on these results the predominant strains of 16SrII phytoplasmas associated with AWB disease in Iran were classified in the 16SrII-D subgroup.

In the present study farmers’ practice (Regime 1: Repeated use of different insecticides viz., Cypermethrin, Monocrotophos, Chlorpyriphos and Triazophos once or twice at weekly intervals) was compared with two IPM regimes, during 2010-12. The IPM regimes were: 1) Regime 2: weekly shoot clipping of infested twigs at the time of infestation along with installation of pheromone traps at 100/ha (lure was changed at 25 days intervals); and 2) Regime 3: weekly shoot clipping of infested twigs at the time of infestation along with installation of pheromone traps at 100/ha (lure was changed at 25 days interval) and need based application of NSKE at 4% and cartap hydrochloride at 1 g/l.

Under field conditions for two seasons and glasshouse experiments, plants treated with salicylic acid showed substantial and significant decrease in the disease severity on the leaves and the stem compared with the control and the fungicide. Salicylic acid was highly effective and controlled the disease better than Carbendazim which provided only partial protection. In vitro, the inhibition of fungal growth was investigated and showed that salicylic acid was the best inhibitor of fungal growth (48%) followed by oxalic (39%), ascorbic (33%) and citric (10%) acids 6 days after incubation. An important increase of total phenols was recorded in treatment by salicylic acid in the healthy and infected leaves of faba bean 12, 24, 48, 72, 96 and 120 hours after inoculation.

Integration of gamma radiation and R. officinalis oil enhanced the mortality of C. maculatus compared with control treatments of either irradiation or fumigation alone. Synergistic effects of mortality on 1-2 days old adults of C. maculatus were observed when exposed to combination of gamma radiation and essential oil. It was found that pretreatment with fumigation followed by irradiation was perfectly effective.
