“…Some of the previously reported as seedborne and pathogenic fungi were recovered from the current seeds [9,25] (Table 1). For cucumber (Cucumis sativa), 7 seedborne fungi were isolated from this vegetable in Bangladesh [28]). These include Aspergillus flavus, A. niger, Fusarium oxysporum, F. moniliforme, Penicillium spp., Doratomyces sp.…”

“…On the other hand, numerous fungi were reported as seedborne and seed transmitted causing many diseases to B. vulgaris [22][23][24], and phylloplane and seedborne mycoflora of C. olitorius were reported [25,26]. Many fungi were reported as seedborne fungi of C. sativa [27][28][29]. Many fungi were either isolated from the seeds of E. sativa [30,31] or as foliar and root diseases [32][33][34][35][36].…”

Seedborne fungi present on or inside the seed or as contaminant with the seed debris adversely affect seed viability, germination, emergence, plant growth vigour and eventually production and productivity. In the present study, seedborne fungi of 7 imported vegetables were examined. 29 species of fungi belonging to 23 genera were recovered from the seeds. Of these fungi, 6 species and one genus are new records to the mycoflora of Sudan, whereas different species are new to the micobiota of these vegetables. These include 15 species for Beta vulagris, Petroselinum crispum (14 species), Solanum melongena (12 species), Portulaca oleracea (8 species and 1 genus), Eruca sativa (5 species and 3 genera), Corchorus olitorius (2 species), and Cucumis sativa (1 species). The seeds were highly contaminated with saprophytic and pathogenic fungi (25-100%), which apparently inhibited seed germination (15-79%) and seedling emergence (12-75%) of these vegetables. The genus Aspergillus and Drechslera (4 species each) were the most prevalent genera followed by Alternaria, Curvularia, Fusarium, Pithomyces (2 species) and 1 species for the remaining genera (Aureobasidium, Beltrania, Chaetomium, Cladosporium, Memnoniella, Microascus, Rhizopus, Sordaria, Stachybotrys, Stemphylium, Trichothecium, Ulocladium, and Wellernia). Therefore, there is urgent need for development of proper standard laboratory seed testing methods, fungal eradication measures, and adopting strong legislations and quarantine regulations. The use of certified and high grade seeds is a priority.

“…The finding was also following Sesan et al (2017) who reported that Allium sativum was the greatest inhibitory activity among nine plant species against Fusarium oxysporum. The use of Allium sativum has a great potential in suppressing several plant pathogenic fungi (Amin et al 2009;Charimbu et al 2009;Panchal and Patil 2009;Su and Cheng et al 2008;Taskeen-Un-Nisa et al 2011;Amsalu et al 2011). The present finding of this study compares to other studies to become sometimes contrary for our study when used common materials that same plants may have different antimicrobial activity in same solvents on different organisms or same organisms.…”

Background: Tomato (Lycopersicon esculentum Mill.) belongs to the family Solanaceae. In Ethiopia, control of early blight is largely dependent on fungicidal application. There is a research need to identify effective botanical extracts to control Alternaria solani that cause early blight of tomato and for evaluation of plant extracts through different solvents on the target pathogen. Methods: In vitro experiment was conducted to evaluate the effectiveness of crude extracts of 16 selected medicinal plants against Alternaria solani. Thus, crude extracts were extracted from medicinal plants with different solvents (methanol, ethanol and petroleum at (25%, 50% and 100%) concentrations. The Alternaria solani was isolated from infected tomato leaves showing early blight symptoms. Evaluation of plant extracts was carried out against Alternaria solani using food poisoned technique on PDA. Result: Results showed that most of the methanolic extract plants were showed significant inhibition of the mycelial growth as compared to ethanolic and petroleum ether extracts. A higher rate of mycelial reduction was recorded by ethanol extracts of Allium sativum at all concentrations (100%) followed by methanol extracts of Allium sativum at 25%, 50%, 100% concentration (90.02%, 97.01%, 100% respectively). The effectiveness of extracts against Alternaria solani depends on use at the higher concentrations and various solvents. For crude extracts that have shown higher inhibitory effects against Alternaria solani in vitro conditions, actual chemical compounds should be identified. Furthermore, it is also important to evaluate these plants on other microbes, study to test in vivo and to assess their real potential field condition wherever early blight is an important disease of tomato.

“…Several botanicals such as Mahogany (Swietenia mahagoni), Neem (Azadirachta indica), Zinger (Zingiber officinale), Marigold (Tagetes erecta), etc. contain several essential compounds which are effectively used to control various crop diseases including anthracnose of chili (Amin et al 2009, Kabir et al 2014. The combination of Trichoderma and botanicals might help to control plant diseases more efficiently in field conditions.…”

Mango production in Bangladesh is enormously affected by the infestation of hopper which punctures and sucks sap from tender shoots, inflorescences, and leaves of mango tree, causing non-setting of fruits and dropping of immature fruits. Control of mango hopper in recent days is solely done by synthetic insecticides. This study was conducted in the laboratory during January to October 2022 to know the toxicity of four commonly used insecticides, namely Desis 2.5 EC (Deltamethrin), Ripcord 10 EC (Cypermethrin), Relothrin 10 EC (Cypermethrin), and Sumithion 50 EC (Fenitrothion) on mango hopper. The doses of Desis 2.5 EC, Ripcord 10 EC and Relothrin 10 EC were prepared as 1200, 1000, 750, 500 and 100 ppm, and Sumithion 50 EC solutions were 2500, 2200, 1500, 1000 and 500 ppm. Results showed that the tested insecticides with their recommended doses revealed 51.4±2.5 to 70.6±1.8% mortality of hopper at 4 hours after treatment where Desis 2.5 EC showed the highest mean mortality of the insect. Desis 2.5 EC also showed the lowest LC 50 and LC 95 values (426.0 and 4331.4 ppm, respectively at 4 hours after treatment) signifying its higher effectiveness compared to other tested insecticides.
