Damping-off |Symptoms, Causes, Control and Management Mamoona Ghaffar
It's an overview about most prevalent plant disease attack on seedlings .the disease incidence is dependent more upon the conditions under which the seedlings are grown than upon the particular species of plant concerned.
Ustilaginoidea virens, perfect sexual stage Villosiclava virens,[1] is a plant pathogen which causes the disease False Smut of rice which reduces both grain yield and grain quality. The disease occurs in more than 40 countries, especially in the rice producing countries of Asia.[2] but also in the U.S.[3] As the common name suggests, it is not a true smut (fungus), but an ascomycete. False smut does not replace all or part of the kernel with a mass of black spores, rather sori form erupting through the palea and lemma forming a ball of mycelia, the outermost layers are spore-producing.[4] Infected rice kernels are always destroyed by the disease.
Symptoms of bacterial infection in plants are much like the symptoms in fungal plant disease.
They include
leaf spots,
blights,
wilts,
scabs,
cankers and a
soft rots of roots,
storage organs and fruit,

Undergraduate students' slide presentation of Plant pathogenesis caused by fungi for SHEQ3329 Agricultural Microbiology under Dr. Khanom Simarani (2014/2015).
Downy mildew of grapes refers to any of several types of oomycete microbes that are obligate parasites of plants. Downy mildews exclusively belong to Peronosporaceae. In commercial agriculture, they are a particular problem for growers of crucifers, grapes and vegetables that grow on vines. slide contains vivid descrition of the plant pathogen.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

• What is plant Disease ?
• Symptoms of plant disease
• Type of plant disease
3. What is plant Disease ?
•Any disturbance of a
plant that interferes
with its normal growth
and development.
4. Symptoms of plant disease
What is symptoms ?
- The external signs on the plant which indicate
disease are called symptoms.
1. Fungal disease symptoms
- Birds eye spot on berries
- Damping off a seedlings
- Leaf spot
- chlorosis
6. Type of plant disease
• A Disease is any abnormal condition that
damages a plant and reduces its productivity
or usefulness to man.
• There are two basic type of Diseases.
1. Non infectious disease (Abiotic)
2. Infectious Disease (Biotic)
7. 1. Non infectious Disease
• Non infectious Disease are caused by
some environmental factor.
- Moisture
- Temperature
- Toxic chemical
- PH etc.
8. 1. Moisture
• Deficient or excessive moisture
(water ) can cause disease.
• Moisture deficiency produces stunted
stressed or wilted plants.
• In addition this stress may predispose
plants to infection by infectious
organisms or increase the effects of
infectious disease.
9. 2 . Temperature
• Frost is common problem in spring and fall
affecting tender farm crops and garden
vegetables.
• Extremely high temperature in summer
can also cause problems.
•Foe examples excess heating causes
scorching in plants.
10. 3. Toxic chemicals
• Toxic chemical injure plant.
• Salt may damage or kill farm crops growing
in saline seeps roads salt may severely
damage boulevard trees and other
vegetation.
• Air pollution also damages vegetation.
11. 4 . PH
• The Soil reaction also plays a major role .
• Acidic pH predisposes the plant to certain
disease. (club roots of cabbage alkaline pH
predisposes the plant to certain diseases.)
12. 2. Infectious Disease
• Infectious disease are not caused by a
living parasitic organism.
- Bacterial
- Viruses
- Nematodes
- phytoplasmas etc.
13. 1. Bacteria
• Bacteria are tiny one celled organisms that
multiply by cell division.
• They can be seen only with a microscope.
• Example of common bacterial disease include
bacterial blights of dry beans , bacterial
blights and black chaff of wheat and barley
14. 2. Viruses
• Viruses are 1000 times smaller than the tiniest living
cell.
• Most viruses have a core of nucleic acid the basic unit
of heredity and have a protein coat covering the core.
• Examples of virus disease that can cause serious losses
are wheat streak mosaic , barley yellow dwarf , bean
common mosaic.
15. 3. Phytoplasmas
• Phytoplasmas lack a rigid cell wall , have no
defined shape and can only be seen with an
electron microscope.
• They are usually systemic in the host and are
transmitted by leafhoppers.
16. 4. Nematodes
• Nematodes are tiny roundworms.
• Most can be seen only with a microscope but a few
can be seen with the naked eye.
• Reproduction is by formation of eggs.
• Some parasitic forms attack plant root and can cause
severe damage.
