This study examined the effects of abiotic (low nitrogen fertilizer) and biotic (southern leaf blight infection) stresses on maize plants and their associated leaf bacterial communities. The maize inbred B73 was exposed to single and combined low nitrogen and high southern leaf blight infection levels. Bacterial diversity was found to decrease under higher southern leaf blight disease severity, and nitrogen fertilization further intensified the decline in bacterial diversity. While no single bacterial species was consistently linked to disease severity, some sets of bacterial types were predictive of disease levels. Differences in early-season leaf bacterial communities were correlated with later plant disease severity, supporting the potential use of epiphytic microbial profiles to predict disease progression.

This document outlines various aspects of rust management in wheat. It discusses three main types of rust that affect wheat yields: leaf rust caused by Puccinia triticina, stripe rust caused by Puccinia striiformis, and stem rust caused by Puccinia graminis. Yield losses from rust can reach 50% for leaf rust, 70% for stripe rust, and 100% for stem rust. The document then covers several methods for controlling rust, including breeding for resistance, genetic modification, biological control using bacteria, agricultural practices like cultivar mixtures and removing alternate hosts, and application of fungicides. It emphasizes using multiple resistance genes and integrated management strategies for effective rust control.

Abstract— In this study, we have used well-known, efficient methods and bioassay for systematic screening of R. solanacearum for identification of its phenotype and biochemical profile, as well as for pathogenicity and virulence. As a result, an aggressive race — Biovar 3 — was most isolated from the potato fields of the Issyk-Kul region, especially in fields where the Picasso variety was grown. The isolated indigenous strains of Streptomyces diastatochromogenesstrain sk-6 and Streptomyces bambergiensis strain k1-3 has the potential to be used as a biocontrol agent for the management of the bacterial wilt of potatoes, as indicated by the reduced percentage wilt incidence. Root zone and soil application of Streptomyces diastatochromogenesstrain sk-6 and Streptomyces bambergiensis strain k1-3 at a dose of 108 cell/ml significantly reduced disease incidence and increased the growth of potato plants. The disease’s progress was reduced by 60% and 56% in plants inoculated with Streptomyces diastatochromogenesstrain sk-6 and Streptomyces bambergiensis strain k1-3, respectively.
This document provides a literature review on breeding approaches for resistance to Maize Lethal Necrosis (MLN) disease in Ethiopia. MLN is caused by a synergistic infection of two viruses, Maize chlorotic mottle virus and Sugarcane mosaic virus, and emerged as a major threat to maize production in Ethiopia in 2014. The review summarizes research on the distribution of MLN, maize response to the disease, conventional breeding methods like backcrossing used to develop resistant varieties, and molecular breeding approaches including marker-assisted selection, genomic selection, transgenesis, and genome editing. It concludes that combining conventional and molecular breeding methods is an important new strategy for developing improved maize genotypes with
Grain mold, considered the most important disease of sorghum, is associated with several fungal genera. The disease reduces both yield and quality. In this study, over 300 sorghum seed samples collected from Texas, Florida, and Georgia were evaluated for grain mold severity, seed weight, germination rate, and seed fungal community. Grain mold severity of the seed samples, except for those collected from Cameron, Texas, were rated 3 or higher, indicating that these sorghum lines were moderately susceptible under naturally-infected field conditions during the 2016 and 2017 growing seasons. Seed weight across surveyed locations ranged from 1.1 g to 4.0g for samples collected in Texas during the same period. Percent germination rates for samples collected in Texas ranged from 59.6% to 86.7%. Sorghum samples collected from Florida and Georgia exhibited moderately susceptible response to grain mold infection. Mean seed weight was 1.9 g for samples collected from Florida, while in Georgia, mean seed weight was 2.3 g. Germination rate was low for samples collected from Florida and Georgia. Mycological analysis of sorghum seed samples collected from farmers’ fields in Central and South Texas during the 2016 and 2017 growing seasons showed Alternaria species as the most frequently isolated fungal genus, accounting for 40% and 42 % in 2016 and 2017, followed by Fusarium incarnatum, F. acuminatum, F. equiseti, & F. semitectum Complex. In Florida and Georgia, Fusarium incarnatum, F. acuminatum, F. equiseti, & F. semitectum Complex was the most frequently recovered fungal species, accounting for 77% and 72% of the total. genera/species isolated from seed samples. Other fungal species, including Curvularia lunata, Bipolaris sp., Colletotrichum sublineola, F. verticillioides, Penicillium sp., Aspergillus flavus, F. thapsinum, F. oxysporum, F. sporotrichioides, F. graminearum, F. proliferatum, and Aspergillus niger were also isolated from sorghum seeds in various frequencies. In conclusion, the presence of large number of fungal genera associated with grain deterioration and their effect on other traits, makes management of this disease complex challenging. To identify grain mold resistant sources in a region, using the most dominant species in that region to screen the sorghum germplasm is recommended.
ABSTRACT- Corynespora leaf fall (CLF) disease of rubber incited by the fungal pathogen Corynespora cassiicola is
one of the major threats for natural rubber cultivation in rubber growing regions of India. The CLF disease occurs
regularly in rubber plantation during dry period after re-foliation and intensity rise during March to April and subsides
during wet months. Study was undertaken to investigate on survival mechanism of the pathogen in rubber plantations over
the seasons. The results of the studies revealed that the pathogen survived up to 11 days in infected leaf litter and showed
good growth on potato dextrose agar medium. The pathogen was able to survive on intact infected leaves on the plant and
also on plant debris as thick dark brown dormant mycelium under the bark of dried infected twigs.

Vancomycin-resistant Staphylococcus aureus (VRSA) is a serious antibiotic-resistant bacterial infection. Overuse and misuse of antibiotics has encouraged the emergence of resistant strains like VRSA. VRSA was first identified in the 1990s and cases have been reported worldwide since then. VRSA poses a major health risk as it can be difficult to treat and has the potential to spread rapidly internationally through human travel and contact. Proper infection control practices and antibiotic stewardship are important to prevent the further emergence and spread of VRSA.

This study investigated how two pathogenic Yersinia bacteria, Y. enterocolitica and Y. pseudotuberculosis, can survive and adapt to acidic environments like orange juice at different pH levels (3.9, 4.0, 7.0). The bacteria were inoculated into orange juice at these pH levels and stored at 4°C for up to 30 days. Results showed that both bacteria survived longer at pH 3.9-4.0 than 7.0. Bacteria surviving at low pH showed increased urease enzyme activity and genetic changes that may help them tolerate stomach acid after ingestion and cause infection. The ability of these pathogens to survive in acidic foods like orange juice has implications for food safety and

The white mango scale insect, Aulacaspis tubercularis (Newstead) (Hemiptera: Diaspididae) is one of the most destructive pests of mango trees in Egypt. The main objective of the present work is to estimate the spatial distribution pattern and minimum sample size for monitoring populations of A. tubercularis on six different cultivars of mango through the two successive years of 2017/2018 and 2018/2019 at Esna district, Luxor Governorate, Egypt. Data on the indices of distribution and Taylor’s and Iwao’s regression analyses indicate significant aggregation behaviour during each year in all the tested cultivars of mango trees, that may be caused by environmental heterogeneity. The regression models of Taylor’s power law (b) and Iwao’s patchiness (β) were both significantly >1, indicating that A. tubercularis had an aggregation distribution with a negative binomial distribution during each year in all the tested mango cultivars. The Iwao regression coefficients were used to determine the optimum sample size required to estimate populations at three fixed precision levels. The optimum size decreased with increased density in all levels of precision (5, 10 and 15%) in all tested mango cultivars. These can be deployed to develop a sampling plan to estimate the population density accurately. Results suggesting that the optimum sample size was flexible and the precision levels of 5 and 10% were suitable for ecological or insect behavioral studies of A. tubercularis where a higher level of precision is required, whereas, for pest management programs, a 15% level would be acceptable. Furthermore, the distribution, different mango cultivars, and sampling protocol presented here could be used as a tool for future research on pest management methods for this pest.

Control of plant diseases can be achieved through various methods:
1. Breeding resistant plant varieties, using chemicals and altering the environment for protection, and implementing quarantine and regulatory measures to control the spread of diseases.
2. The amount of disease is determined by the interaction between the host, pathogen, and environment, known as the disease triangle. Control strategies aim to reduce one or more components of this interaction.
3. Common control methods include using resistant plant varieties, biological controls like antagonistic microorganisms, cultural practices that manipulate the environment, legislative controls on movement of plants/materials, and application of pesticides and fungicides.
This review article summarizes biocontrol strategies for managing Colletotrichum species that cause anthracnose disease in postharvest fruits. It discusses strategies using bacteria, filamentous fungi, and yeasts to control three main Colletotrichum clades: C. acutatum, C. gloeosporioides, and C. truncatum. The most effective bacterial biocontrol agents for C. acutatum were Bacillus subtilis, Paenibacillus polymyxa, and Bacillus amyloliquefaciens. Filamentous fungi like Cryptococcus laurentii and Aureobasidium pullulans showed promise for controlling multiple Colletotrichum species. Several
This document discusses a study on managing Valsa canker disease of apple trees through adjustments to tree potassium nutrition. The study found that higher leaf potassium levels in apple trees were correlated with lower incidence and severity of Valsa canker disease. Greenhouse and field experiments demonstrated that increasing potassium fertilization enhanced apple tree resistance to the Valsa canker fungus and significantly reduced disease incidence. Proper management of tree nutrition, especially maintaining optimal potassium levels, shows promise as an effective strategy for controlling this destructive apple disease.

Control of plant diseases can be achieved through various methods:
1. Breeding resistant plant varieties, using chemicals and altering the environment for protection, and implementing quarantine and regulatory measures to control the spread of diseases.
2. The amount of disease is determined by the interaction between the host, pathogen, and environment, known as the disease triangle. Control strategies aim to reduce one or more components of this interaction.
3. Common control methods include using resistant plant varieties, biological controls like antagonistic microorganisms, cultural practices that manipulate the environment, legislative controls on movement of plants/materials, and application of pesticides and fungicides.
This review article summarizes biocontrol strategies for managing Colletotrichum species that cause anthracnose disease in postharvest fruits. It discusses strategies using bacteria, filamentous fungi, and yeasts to control three main Colletotrichum clades: C. acutatum, C. gloeosporioides, and C. truncatum. The most effective bacterial biocontrol agents for C. acutatum were Bacillus subtilis, Paenibacillus polymyxa, and Bacillus amyloliquefaciens. Filamentous fungi like Cryptococcus laurentii and Aureobasidium pullulans showed promise for controlling multiple Colletotrichum species. Several
This document discusses a study on managing Valsa canker disease of apple trees through adjustments to tree potassium nutrition. The study found that higher leaf potassium levels in apple trees were correlated with lower incidence and severity of Valsa canker disease. Greenhouse and field experiments demonstrated that increasing potassium fertilization enhanced apple tree resistance to the Valsa canker fungus and significantly reduced disease incidence. Proper management of tree nutrition, especially maintaining optimal potassium levels, shows promise as an effective strategy for controlling this destructive apple disease.

Pseudomonas fluorescens as plant growth promoting Rhizo- Bacteria and biologi...Innspub Net
The use of plant growth promoting rhizobacteria (PGPR) to control disastrous diseases in many crops has been considered important recently. The research was conducted to evaluate several bacterial strains to control white rust in chrysanthemum. The research consisted of two chronological experiments, in vitro and in vivo testing of bacterial isolate against the disease. 16 bacteria isolates were collected, purified and applied on the rust-infected leaf. Three isolates showed more effective in suppressing white rust during in vitro testing and further identification confirmed these strains, Pf Kr 2, Pf Smd 2 and Pf Ktl were grouped into P. flourescens. In vivo testing of the Pf isolates also revealed consistent performances of these three Pf isolates in retarding the growth of fungal Puccinia horiana and even more effective than Azotobacter sp. and Azospirilium sp. The production of ethylene on the leaf was coincidence with the slower development and lower disease intensity on the treated plants. Among the three strains, Pf Kr 2 showed stronger suppression to the disease. Further investigations are needed to further elucidate the existence of specific interrelation between Pf strains and plant genotypes or cultivars. Prior to a selection of good bacterial inoculants, it is recommended to select cultivars that benefit from association with these bacteria.

Demand and Supply Situation for Medicinal PlantsAI Publications
From 2020 to 2015, it was predicted that the demand for medicinal plants in India will increase at an annual pace of between 17 and 23 percent to meet the needs of both domestic and international consumers. Small-scale farmers stand to gain financially and economically from a well-organized medicinal plant production and administration system. Ayurveda, Unani, and Siddha are the three main Indian medical traditions, and together they are expected to bring in more than $500 million annually. In 2015, the gap between demand and supply of MAPs was predicted to be between 50,000 and 250,000 tons. In 2020, this hole was predicted to grow from 250,000 to 500,000 metric tons. Modified accelerated production (MAP) industries provide labor opportunities in economically depressed states, raising the standard of living and tax base of the area.

Vegetable Microbiology: Concern for Human Health | Crimson PublishersCrimsonpublishersCJMI
In the health conscious society of 21st century, vegetables
form an integral part of human diet. They provide us essential
vitamins and minerals, dietary fiber, phytochemicals, and also
help in reducing the risk of dangerous diseases [1]. World Health
Organization (WHO), European Food Safety Authority (EFSA), Food
& Agricultural Organization (FAO) and French Agency for Food
Safety (AFSSA) recommended the intake of atleast five servings
of vegetables and fruits per day [2]. In general, freshly consumed
vegetables are considered to be more vital than the cooked ones.
However, they are usually accompanied with many food borne
diseases, thus poses safety threats [3]. Ready to Eat (RTE) vegetables,
generally grown near the metropolitan cities are cultivated in
unhygienic environments [4], irrigated with poor quality water
[5], and fertilized using organic and inorganic amendments [6,7].
This all leads to microbial contamination and spread of infectious
diseases like diarrhoea, Salmonellosis and Shigellosis etc. in
humans. Bacteria are reported to be the major villain (Figure 1)
among the causes of food borne illness [8]. Bacteria associated or
isolated from different raw vegetables have been documented in article entitled “Recent Trends in Microbiological Safety of fruits and vegetables” by [9].
