In the present study, we evaluated the antifungal activity of Bunium persicum essential oil (EO) and its main constituents on mycelial growth, sporulation and spore germination inhibition of C. lindemuthianum. The main objective of this study was to investigate the effect of EO and its main constituents on decreasing the activity of cell wall degrading enzymes (CWDEs) produced by C. lindemuthianum, which are associated with disease progress. Also, the effects of seed treatment and foliar application of EO and its main constituent, cuminaldehyde, on anthracnose disease severity was investigated. The essential oil of B. persicum, was obtained by using a clevenger apparatus and its major constituents were identified by gas chromatography-mass spectrometry (GC-MS). The EO was characterized by the presence of major compounds such as cuminaldehyde (37.7%), γ-terpinene (17.1%) and β-pinene (15.4%), which indicated antifungal effects against C. lindemuthianum. This pathogen did not grow in the presence of EO, cuminaldehyde and γ-terpinene, β-pinene at 1,500; 1,010 and 1,835 ppm concentrations, respectively. Also, sporulation and spore germination of C. lindemuthianum was completely inhibited by EO and cuminaldehyde. Synergistic effects of the main constituents showed that combing γ-terpinene with cuminaldehyde induced a synergistic activity against C. lindemuthianum and in combination with β-pinene caused an additive effect. Activities of pectinase, cellulase and xylanase, as main CWDEs, were decreased by EO and its main constituents at low concentration without affecting mycelial growth. Seed treatment and foliar application of peppermint EO and/or cuminaldehyde significantly reduced the development of bean anthracnose. We introduced B. persicum EO and constituents, cuminaldehyde and γ-terpinene, as possible control agents for bean anthracnose.","PeriodicalId":16848,"journal":{"name":"Journal of Plant Protection Research","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41709952","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}

Therefore, the aim of this study was to assess the control failure likelihood of Plutella xylostella and the physiological selectivity active ingredients to parasitoid Oomyzus sokolowskii (Hymenoptera: Eulophidae) and to predators Polybia scutellaris (Hymenoptera: Vespidae) and Lasiochilus sp. (Hemiptera: Anthocoridae). In bioassays, P. xylostella larvae and O. sokolowskii, P. scutellaris and Lasiochilus sp. adults were used. Concentration-mortality curves of six insecticides for P. xylostella were established. These curves were used to estimate the mortality of P. xylostella at the recommended concentration, in order to check a control failure of insecticides to this pest. Furthermore, the lethal concentration for 90% of populations (LC90) and the half of LC90 were used in bioassays with the natural enemies to determine the selectivity of these insects to insecticides. All tested insecticides showed control failure to P. xylostella, indicated by high LC90 and low estimated mortalities (less than 80%). The cartap insecticide was selective in half of LC90 to Lasiochilus sp. and moderately selective in LC90 and the half of LC90, to Lasiochilus sp. and P. scutellaris, respectively. Deltamethrin was moderately selective in the half of LC90 to predator Lasiochilus sp. Cartap, carbaryl, and deltamethrin reduced the mortality of Lasiochilus sp. in the half LC90. The results also showed that the insecticides methamidophos, carbaryl, parathion methyl and permethrin were not selective to any of the tested natural enemies. The role of insecticides in IPM systems of Brassica crops is discussed based on their control failures to P. xylostella and selectivity to their natural enemies.","PeriodicalId":16848,"journal":{"name":"Journal of Plant Protection Research","volume":"1 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68943170","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}

A number of 16 fungal isolates were isolated from tomato plants displaying the above symptoms. These isolates were classified as belonging to six species, namely: Alternaria solani, Chaetomium globosum, Fusarium solani, Fusarium oxysporum, Pythium spp. and Rhizoctonia solani. Isolates of Pythium spp. were prevalent and were found to be more pathogenic than the other fungal isolates. This species causes damping-off, root rot, sudden death, stem rot and fruit rot. The pathogen was identified as Pythium aphanidermatum based on morphological, cultural, and molecular characteristics. Biogenic silver nanoparticles (AgNPs) were produced using the F. oxyspo rum strain and characterized by transmission electron microscopy (TEM). The size of these spherical particles ranged from 10 to 30 nm. In vitro, biogenic AgNPs showed antifungal activity against P. aphanidermatum. In greenhouse and field experiments, AgNPs treatment significantly reduced the incidence of dead tomato plants due to root rot caused by P. aphanidermatum compared to the control. All of the investigated treatments were effective and the treatment of root dipping plus soil drenching was the most effective. To the best of our knowledge, this study describes P. aphanidermatum on tomato in Egypt for the first time. Also, biogenic AgNPs could be used for controlling root rot disease caused by this pathogen.","PeriodicalId":16848,"journal":{"name":"Journal of Plant Protection Research","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48398897","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}

This research involved the monitoring of winged morphs of aphids in allotment gardens in the area of Poznań with the use of Moericke traps. The fauna structure of aphids in two large allotment gardens was demonstrated by comparing the activity of winged morphs of aphids in 2000–2001 and 2014–2015. The vegetation of these gardens was accompanied by the rich fauna of aphids. For four growing seasons, 113 species or groups of aphid species were captured with the traps. Major changes were reported in the structure of the collected fauna in the period of time when the research was conducted. The differences concerned particular positions of collected species in aphid communities. The abundance of Anoecia corni, Aphis sambuci, Phorodon humuli and Periphyllus testudinaceus increased, and now hold the position of subdominants of the communities, whereas Myzus persicae and Hyalopterus pruni decreased in comparison with the situation more than ten years ago. Rhopalosiphum padi still remains an eudominant in the communities. The main reason for this phenomenon is thought to be due to changes in the vegetation composition of gardens because the gardens are being used differently. The production function has changed to recreation.","PeriodicalId":16848,"journal":{"name":"Journal of Plant Protection Research","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44218799","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 improve and enhance the detection procedure, a colorimetric loop-me-diated isothermal amplification (LAMP) technique was developed. Six LAMP primers were newly designed and tested to determine the optimal conditions using a recombinant plasmid of CSVd as a DNA template. The optimal conditions for colorimetric LAMP were incubation at 65°C for 45 min. Under these conditions, a ladder-like pattern of LAMP products was detected along with a change of color from pink to yellow in the positive reactions. Limits of the detection (LOD) of colorimetric LAMP were up to 1 fg ∙ µl –1 of plasmid DNA concentration which was 10 4 times greater than that of polymerase chain reaction (PCR). The developed colorimetric LAMP was not cross reacted to other viruses and viroids. From detection of actual samples and chrysanthemum plantlets which were obtained from meristem tip culture, the colorimetric LAMP showed effective potential in detecting CSVd. Therefore, the colorimetric LAMP can be used as a main technique to detect CSVd and ensure CSVd-free chrysanthemum plantlet production due to its accuracy, rapidness and sensitivity.","PeriodicalId":16848,"journal":{"name":"Journal of Plant Protection Research","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45700223","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 two used products were Biosept Active Spray (grapefruit extract) and Miedzian 350 SC (copper oxychlo-ride) which were sprayed on mulberry leaves used to feed silkworms from the beginning of the 4th instar. As to measure the level of impact, the mortality of larvae (percentage of dead specimens) and cocoon shell ratio (percentage of shell weight in whole cocoon) were checked. The highest mortality was recorded in the group treated with 0,7% Miedzian solution (92,5%) as well as the lowest shell ratio (12,06) comparing to the control group (mortality 7,5% and shell ratio 17,43). In the Biosept group, no significant mortality was recorded (comparing to the control group) but mean shell ratio showed a significant decrease in the cocoon quality.
