Experiment consists of 8 treatments (neem extract, tobacco extract, garlic extract, datura extract, lantana extract, eucalyptus extract, flonicamid (synthetic insecticide) and control following RCB Design with 3 replications. Treatments were applied thrice after 15 days interval. Results revealed that the three times application of the tested treatments showed varying toxicity against S. dorsalis 24, 48, 72 hours and 7 days after spray applications while ladybird beetle and green lacewing were also significantly affected when recorded 7 days after spray application. However, Flonicamid 50%WG proved to be the most effective till 7th and had lowest pest population followed datura and neem extract. neem extract in all the three spray application . Garlic and eucalyptus also produced significant results compared to control. Neem, tobacco, datura and flonicamid were found to be comparatively more hazardous to ladybird beetle and green lacewing population compared to eucalyptus, garlic and lantana to in all three spray application. Tomato yield was highest with flonicamid (12533 kg/ha) followed by datura and neem (11810 kg/ha and 11300 kg/ha) respectively, while lowest (8133 kg/ha) in control. It is concluded from the current research that flonicamid performed better against S. dorsalis but comparatively more hazardous to natural enemies however lantana, garlic and eucalyptus extract showed better result against S. dorsalis and comparatively safe towards natural enemies thus recommended to be incorporated in IPM program.","PeriodicalId":17469,"journal":{"name":"JOURNAL OF WEED SCIENCE RESEARCH","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89535999","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}

Okra seeds of cultivar Swat Green were planted into two different types of sowing methods (ridges and flat beds), and reduced to various number of picking (3, 4, and 5 intervals). The results of the present study revealed that okra plants sown on the ridges recorded maximum germination percentage (96.9%), fruit weight (22.41g), pod length (14.44 cm), seed pod-1 (48), 100 seed weight (6.41 g), seed yield (102.2 kg ha-1) and fresh yield (0.165 tons ha-1). Data regarding number of picking intervals showed that maximum germination percentage (92.7%), fruit weight (20.97 g), pod length (12.25 cm), highest seed yield (103.3 kg ha-1), and seed pod-1 (43) were recorded in 3 pickings. Whereas, data for maximum 100 seed weight (6.6 g) for picking intervals was recorded in 4 pickings and maximum fresh yield (0.148 tons ha-1) in 5 pickings. Infestation of weeds can cause a significant loss in okra yield which needs urgent integrated management. Cyperus rotundus, Echinochloa crusgalli and Digitaria sanguinalis were the main weeds observed during the study against which local farmers used various manual, mechanical and chemical control methods. It is concluded that okra plant sown on ridges and almost 3 picking intervals have significantly affected the growth and seed yield. Excessive use of chemical herbicides should be avoided to prevent environmental and human health hazards.","PeriodicalId":17469,"journal":{"name":"JOURNAL OF WEED SCIENCE RESEARCH","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83807725","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}

The phenomenal size properties enable nanoparticles to anchor a prominent place in various biomedical applications. Silver is known for its antimicrobial nature. This study elucidates the qualitative phytochemical properties of three plant extracts, its biogenic synthesis of silver nanoparticles and their antimicrobial activity. Green Silver nanoparticles (AgNPs) were synthesized from 1mM Silver Nitrate (AgNO3) solution using leaf extracts of Cynara scolymus (Artichoke), Alkanna tinctoria (Alkanet), and Lavandula angustifolia (Lavender) respectively. The synthesized silver nanoparticles were characterized visually, via UV–vis spectrophotometer and X-ray Diffraction (XRD). The biogenic particles were tested against pathogenic bacterial strains (Staphylococcus aureus, and Escherichia coli) and Plant pathogenic fungal strains (Aspergillus flavus and Aspergillus niger). The formation of AgNPs with size <100 nm was ensured by UV vis spectrophotometer and XRD. Antibacterial activity of lavender mediated AgNP was highly significant, followed by artichoke mediated AgNP and finally, alkanet AgNP were effective. However, in contrast, Artichoke mediated AgNP showed significant activity against plant fungal strains, followed by Alkanet AgNP, and finally by Lavender mediated AgNPs. We concluded that the three plants have versatile biochemical molecules responsible for broad spectrum of AgNP against bacterial and fungal strains. Studies on combined use of AgNPs with other antimicrobial agents may solve the problem of toxicity and possible risk of drug resistance.","PeriodicalId":17469,"journal":{"name":"JOURNAL OF WEED SCIENCE RESEARCH","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89030713","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}

There were five different locations in district Chitral from where the soil samples were collected which included Drosh, Shen Lasht, Garam Chashma, Ayun and BoonyLasht. A total of 300 samples were collected from all locations with 60 samples from each location. The 300 soil samples collected were placed in trays of medium sizes i.e. 27 cm x 21 cm x 4 cm = 2268 cm3. The trays were arranged in three repetitions having 100 samples in each repetition. Each repetition of 100 samples contained samples from 5 locations, in each location 4 sites (east, west, north and south each at 100 m distance from each other) and at each site samples were collected from 5 different depths, making a total of 100 samples in one repetition i.e. 5 x 4 x 5 = 100 and with repetitions making a total of 300 samples in one district. The results indicated that in the soil samples of district Chitral a total of 31 noxious weeds were recorded. Out of the 31 different weeds, 23 were broad leaves, eight were grasses and one was sedge. In another angle, 24 weeds were annuals while the rest were perennials out of the 31 weeds identified. A total of 17 different plant families were represented by the weeds recorded in the soil samples of Chitral region. Among the different locations of Chitral, the highest weed seed bank was recorded in the soil samples of ARS Shen Lasht area. Weed seed banks have always been higher in areas with mild winters, where the Shen lasht area is having milder winters as compared to the other areas in Chitral. The lowest seed bank was recorded in the soil samples of Garam Chashma, which was however statistically at par with the rest of the locations studied in Chitral. As far as the seed banks in the depths are concerned, largest weed seed bank was observed in the depth of 6 to 12 cm. The smallest seed bank was at the depth of 30 cm followed by the depth of 24 and 18 cm. Therefore, it is evident that the major weed seed bank lies in the upper 6-12 cm depth of the soil. In case of the interaction, the largest weed seed bank was recorded at ARS Sheen lasht at the depth of upper 6 cm of the soil profile whereas the weed seed bank was very low below the 12cm depth of soil upto 30 cm in the Garam Chashma area of Chitral. Out of the total 31 weeds recorded in soil samples of Chitral, the top 10 weeds in terms of the relative weed densities, relative weed frequencies and importance value indices were Convolvulus arvensis, Rumex crispus, Poa annua, Galium aparine, Avenafatua, Trianthemaportulacastrum, Silybum marianum, Sorghumhalepense, Euphorbia helioscopia, and Loliumtenulentumspecies. The IVI values for these weeds were 14.01, 13.96, 13.07, 11.83, 11.57, 11.12, 10.35, 10.09, 10.02, and 9.99, respectively.
