This document discusses crop pests and diseases. It introduces how pests and diseases damage crops, lower yields and quality, and increase production costs. To effectively manage these issues, it is important to understand pest life cycles, feeding habits, and causes of crop disease. The document then discusses different types of crop pests, both direct and indirect, and some examples. It also outlines several negative effects of crop pests, such as destroying seeds, damaging roots, and lowering photosynthesis. Pests are classified in the document according to their feeding method, the crops they attack, the damage they cause, and their scientific grouping.
The broadest definition of plant disease includes anything that damages plant health. This definition can include such diverse factors as pathogens, insufficient nitrogen, air pollution, lawnmower damage, and deer damage.

Eco friendly management of fungal seed borne pathogens through bio-agentsAnkit Chaudhari
Seed borne diseases causes heavy losses in the crops at all stages of growth like seed germination, seedling and maturity of plants.
Bio-control technologies have gained momentum in disease control of crop plants, in recent times as these technologies not only minimize or replace the usage of harmful chemical pesticides, but also found to be ecofriendly, environmentally safe, cheaper and efficient in certain disease control programmes.
Fungal bio-control agents like Trichoderma spp. successfully used for the control of many seed borne diseases caused by Aspergillus spp., Alternaria spp., Curvularia spp., Colletotrichum spp., Fusarium spp., Pyricularia spp., Helminthosporium spp. etc. in several crops.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
2. Introduction
Pests and diseases cause damage to crops; in fields and stores.
They lower crop growth rates hence reduced yield and quality of crop products.
They also raise the cost production in the effort to eliminate them thus lowers
farmers’ gross margins or profits.
To manage crops and diseases effectively and at minimal costs, one must
understand the pests’ life cycles, feeding habits, damages they cause and their
natural enemies. It is also of essence to know causes and effects of diseases.
3. CROP PESTS AND THEIR CONTROL
A crop pest is a living organism that destroy crops; directly or indirectly.
Direct destruction includes physical damage to the plant while indirect
includes introduction of disease-causing organisms (pathogens); viruses,
bacteria or fungi.
Examples of crop pests include; insects, nematodes, birds, rodents, mites and
large animals such as elephants. Some birds are also pests.
Domestic animals can become pests if not take good care of.
4. Negative Effects of Crop Pests
Unearth planted seeds resulting in low plan population e.g. squirrels.
Damage crop roots leading to wilting and death of crops e.g. nematodes.
Destroy leaves thereby reducing photosynthetic area thus lowering crop yields.
The pests that suck plants’ sap deprive them food leading to retarded growth.
Lower crop quality and quantity by attacking fruits, berries and/or flowers.
Attack and destroy embryo of seeds and lowering their germination potential.
Some pests transmit crop diseases e.g. aphids while other give way to secondary
infections.
Some e.g. stalk borers consume growing parts causing retarded growth.
6. According to the mode of feeding continued
ii. Piercing and sucking mouth parts e.g. an aphid
7. CLASSIFICATION OF PESTS contd…..
2. According to crops attacked
Some pests are very specific to the crops they attack e.g. coffee pests.
8. CLASSIFICATION OF PESTS contd…..
3. Stage of development at which pest is harmful/destructive.
4. Stage of growth of the crop attacked.
5. Scientific classification.
6. The level of damage caused.
7. The habitat of the pest/ ecological niche of the pest.
