Leaf blight and root rot indices were 3 when fungal pathogen was inoculated alone and indices were 5 when pathogens were inoculated together. Use of R. irregularis/NPs with A. dauci/R. solani reduced indices to 2, indices were reduced to 1 when R. irregularis was used with SiO2 NPs. Root colonisation by R. irregularis was higher when alone but reduced in plants sprayed with NPs. Inoculation of test pathogens reduced colonisation by R. irregularis.

Spores of all the isolates were observed under scanning electron microscope (SEM) and light microscope for spore size, spine length and colour. Differences in colony characters were observed where the highest mycelial growth was observed in isolate Uv2 with 5.33 cm colony diameter and lowest mycelial growth was observed in Uv9 (3.70 cm). Most of the isolates produced white and circular colony. Spores of all the isolates observed under a light microscope appeared to be olive green in colour, however, a significant variation in spore size and spike length under SEM was observed. Spores size and spike length of different isolates ranged between 4.533 μm to 6.169 μm and 362.567 nm to 799.533 nm, respectively.

Cowpea is one of the most highly consumed grain legumes in Nigeria, but its yearly production is usually affected by fungi attacks. Disease presenting browning of the aerial parts of the cowpea plant was observed during the dry season between 2021 and 2022 in the country. This disease caused stunted growth in the affected plant stand. The fungi were isolated from the symptomatic aerial parts. The fungi were viewed under the microscope and identified by molecular and phylogenetic tools using the Internal Transcribed Spacer (ITS) gene region. The fungi isolated from the symptomatic aerial part of cowpea were identified as Nigrospora sphaerica and Culvularia penniseti. The pathogenicity of the isolated fungi was tested on detached leaves and stems and on intact cowpea seedlings. The test gave a positive result, which confirms the pathogenicity of the isolated fungi on the cowpea plant. This is the first report of N. sphaerica and C. penniseti infecting cowpea cultivated on farmland in Nigeria. Early detection of foreign fungi causing disease in the country’s cowpea crop will aid researchers in addressing the negative effects on crop yield.","PeriodicalId":8323,"journal":{"name":"Archives of Phytopathology and Plant Protection","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2023-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48077749","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}

Samples were tested against carrot virus Y (CarVY), carrot red leaf virus (CtRLV), carrot red leaf virus-associated RNA (CtRLVaRNA), carrot mottle virus (CMoV), carrot torradovirus 1 (CaTV), carrot yellow leaf virus (CYLV), carrot thin leaf virus (CTLV) and cucumber mosaic virus (CMV) agents by Reverse Transcriptase-PCR (RT-PCR). To determine phytoplasmas, samples were tested using universal primers by nested PCR. Molecular tests conducted to investigate the aforementioned viruses produced negative results, but phytoplasma infections were widely found. 16SrVI-A “Candidatus Phytoplasma trifolii” and 16SrI-B “Aster yellows” subgroups were detected by in vitro/in silico RFLP and sequencing analyses.

The process of evolution of resistance in various cotton insects directly affects the life of people. Among the cotton insect pests, pink bollworm (Pectinophora gossypiella) and army bollworm (Spodoptera litura) have turned out to be destructive. The development of seed using gene stacking approach has tremendously reduced the applications of agrochemicals making the technology greener for society. A gene cassette containing Cry11 and Cry1H genes was constructed. The cassette was cloned into the pCAMBIA2300 plant expression vector using the CAMV3-35S promoter. The construct was transformed into cotton line FBS-222 using the shoot apex-cut Agrobacterium-mediated transformation method. The expression of the Cry genes was 3-fold higher in transgenic than the non-transgenic cotton plants using qRT-PCR. Finally, the insect bioassay with transgenic cotton showed 90% mortality against pink bollworms and 80% against cotton army bollworms. The results demonstrate the development of seeds using the gene pyramiding approach is an effective strategy to control insect pest attacks.","PeriodicalId":8323,"journal":{"name":"Archives of Phytopathology and Plant Protection","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2023-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48576196","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}

Colony growth and conidia characteristics of both isolates showed high resemblance with Colletotrichum species in the C. gloeosporioides species complex. Molecular characterisation of the isolates using the partial internal transcribed spacer rDNA and TUB2 regions identified the pathogens as C. tropicale MBRAM001B and C. siamense MBRAM003B. Leaf spots developed on rambutan leaves three days after inoculation and the same pathogens were isolated from the diseased leaves, establishing Koch’s Postulate. In conclusion, this study identified C. tropicale MBRAM001B and C. siamense MBRAM003B as causal agents of leaf spots in rambutan species in the Philippines.

The treatments each replicated thrice were factorially combined and laid out in a split-plot design with four tomato varieties namely: UC-82, Dan Syria, Roma VF and Tima and three concentrations of amorphous silica nanoparticles (1000 ppm, 2000 ppm and 3000 ppm) and cypermethrin (as a check). Insecticides were applied during the fruiting stage at 7 days interval for 8 weeks. Larval holes and marketable fruit yield were recorded. Silica nanoparticles at 3000 ppm resulted in fewer larval population (39.25) at p < 0.05 with a resultant decrease in number of damaged fruits (36.58) as compared to lower doses of 1000 ppm and 2000 ppm. Cypermethrin also gave minimum population of larvae (39.12). In all tested varieties, Roma VF had the lowest larval population (28.79). Variety Roma VF in combination with both cypermethrin and silica nanoparticle at 3000 ppm resulted in lower larval population (19.67) and (28.67) respectively. These results show that silica nanoparticle at 3000 ppm acting together with Roma VF appreciably controls H. armigera in tomato, making both practices important components of IPM against this larval pest.","PeriodicalId":8323,"journal":{"name":"Archives of Phytopathology and Plant Protection","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2023-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42839273","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}
