“…Though mixed infections due to Fol and Fs have been reported globally (Abdesselem et al, 2016) in India, no mixed infections have been reported (Sidharthan et al, 2019). In assessing the genetic diversity of 18 isolates of the two species representing the four Indian states using ITS sequences, the isolates of either of the species did form a distinct group.…”

Though the vascular wilt of tomato caused by the species of Fusarium is globally reported to be a complex disease in certain countries, for example, India, our studies indicated that the disease is caused by either Fusarium oxysporum f. spp. lycopersici (Fol) or Fusarium solani (FS) with the Fol being widely prevalent. In assessing the genetic diversity of 14 Fol strains representing the four Indian states by the unweighted pair group method with arithmetic averaging using Inter Simple Sequence Repeat (ISSR) amplicons, the strains distinguished themselves into two major clusters showing no correlation with their geographic origin. In pot experiments under polyhouse conditions, the seed dressing and soil application of a talc-based formulation of a biocontrol treatment, TEPF-Sungal-1 (Pseudomonas putida) + S17TH (Trichoderma harzianum) + CG-A (Chaetomium globosum), which inhibited Fol, was equally effective like the cell suspensions and was even better than the fungicidal mixture (copper oxychloride-0.25% + carbendazim-0.1%) in promoting the crop growth (52.3%) and reducing vascular wilt incidence (75%) over the control treatment, despite the challenge of inoculation with a highly pathogenic TOFU-IHBT strain. This was associated with significant expressions of the defense genes, indicating the induction of host resistance by a biocontrol consortium. In field experiments on two locations, the bioconsortium was highly effective in recording maximum mean fruit yields (54.5 and 60%) and a minimum mean vascular wilt incidence (37.5%) in comparison to the untreated control. Thus, Chaetomium-based bioconsortium demonstrated consistency in its performance across the two experiments in 2 years under the two field conditions.

Fusarium cotton wilt (FW) is one of the most economically devastating cotton diseases worldwide and the threatening agent of this disease is Fusarium oxysporum f.sp. vasinfectum (FOV). This study aimed to add more information towards the isolation and identification of F. oxysporum f. sp. vasinfectum (FOV), which could probably be responsible for the wilting of their corresponding host, Gossypium hirsutum. Roots samples were collected from plants showing typical symptoms of wilting from three different regions (Kasur, Faisalabad, Multan) of province Punjab, Pakistan. For further analysis, samples were immediately transported to the microbiology laboratory of Government College University Faisalabad, Pakistan (GCUF). After surface sterilization of root, each cut piece (5 mm) of the root was inoculated on Potato Dextrose Agar (PDA) media and incubated at 25°C±2 °C for 7 days. The different obtained co1lonies were identified using the standard microbiological techniques such as macro-morphological, microscopic, and Polymerase Chain Reaction (PCR). The pathogenicity test was also performed in the greenhouse for confirmation of Koch's postulate. This test showed that plants infected with FOV start wilting and yellowing of leaves which confirmed that FOV was linked with cotton wilt and responsible for significant economic loss. Good agricultural practices and proper management of FOV will permit the production of healthy seedlings and subsequently aid in the improvement in cotton yield.

Tomatoes (Lycopersicon esculentum L.) are the most extensively grown vegetable in the world. It belongs to the Solanaceae family and is commonly planted for its tasty fruits. Pests, weeds, diseases, and parasites are just a few of the numerous variables that significantly affect tomato growth and yield. The most common disease affecting tomatoes is fusarium wilt. Fifteen rhizobacterial strains were identified by morphological and biochemical analyses in this work, and they were employed as an antagonist against Fusarium oxysporum f.sp. lycopersici. Fifteen isolates were investigated for their antagonistic properties against Fusarium oxysporum f.sp. lycopersici using an invitro dual culture approach. The growth of Fusarium oxysporum f.sp. lycopersici was suppressed by each isolate. Out of the 15 rhizobacteria isolates, isolate RBS-5 exhibited the highest level of growth inhibition and strongly suppressed the development of Fusarium oxysporum f.sp. lycopersici, resulting in a 57.28 percent reduction in pathogen growth as compared to the control. The development of Fusarium oxysporum f.sp. lycopersici was suppressed by isolates RBS-12, RBS-6, and RBS-15, in decreasing order of merit, compared to the control by 53.7, 51.91, and 51.73 percent. Isolate RBS-13 showed the least amount of pathogen growth inhibition 20.83 percent. The data was statistically analyzed.
