Importance of Agricultural Parasites


Importance of Agricultural Parasites


1.       Late  blight : phytophthora infestans

Pathogen description:

·         Late blight of potato is a devastating disease caused by an oomycete, phytophthora infestan.
·         It requires living plant tissue for growth , but can survive on dead plant material for a limited time.
·         In the 1990s it was shown that p.infestans is not a fungus, it was reclassified as a member of protists. P.infestans also cause late blight of tomato attacking both leaves and fruit.

Symptoms


  •          Leaves, stems and tubers may all be infected.
  •          Water soaked spots appear on leave, turn purple brown & finally black color.
  •          White growth develops on underside of the leaves.
  •          Stem breaks at these points and the plant fall.
  •          In tubers- purplish brown spots & spread to entire surface.
  •        Tuber show rusty brown necrosis spreading from surface to the center.


Mode of infection



  •        Spores germinate on the leaf surface, producing germ tubes which penetrate epidermal cells.
  •          Rain can wash spores into the soil where they infect young tubers, and the spores can also travel long distances on the wind
P.infestans initially lives off the plant tissue without killing it. Later, it switches to necrotrophic  growth, resulting in cell death and the appearance of necrotic lesions(dead tissue) on the infected tissue.

Mode of spread and survival


  •          Infected tubers and infected soil-source of primary infection
  •          Survival of parasite in fruiting stage or as dormant parasite in the soil
  •          Persisting parasite in affected tubers from the field, stored and used as seed in next season

Epidemiology

·         Cool  and humid ( above 90% ) weather with rains alternating with warm moist period.

Control


  •          Breeding for disease resistant varieties of plant.
  •          Bruising tubers at harvest should be avoided.
  •          Regular spraying during growing season gives effective control 10-15 days interval.

Pragmatism

Pragmatic philosophy started by the Greek philosopher Heraclius, but the spread of this philosophy was coupled with name of the American philosopher John Dewey. It considers that everything must be experimented in order to prove it, therefore it represents a new progressive trend in philosophical thoughts.

Basic principles of pragmatic philosophy

Among the basic principles of pragmatic philosophy are those which emphasize that the individual is part of society and has a certain role in it. Adding to that, man has a neutral nature, since he is neither good nor bad but he has the willingness to be this or that, depending on the type of education reveived. Other principle is that knowing the divine self and how the universe exists is impossible.

Role of students

Regarding the role of student, pragmatist sees that students should collaborate with others, able to solve problem by self, and producing new methods for solving them. Pragmatists prefer students to have a well developed personality with the ability to communicate socially and self proof.

Role of teachers

Pragmatists ensure that teachers should suggest problems and lead students to find ways to solve them,  also teach them how to think and work. What is important that building educational attitudes on problems to better understand the surrounding.

Methods and curriculum

Pragmatists do not advocate a fixed curriculum in advance, yet it should be evolved according the requirement of situations. Thus pragmatists claim to flexible curriculum so that the nature of the learner has to be taken into consideration. Pragmatists try to include activities from daily life into the curriculum. It emphasizes only utilitarian aspect therefore, neglect subjects like poetry and art. Learning by doing is one of the basic methods of teaching in pragmatism. It is applied by encouraging students to learn through self-effort , not by reading books, but by actual doing things. Also including real life situations with topics learned in class. The learner is given a real and purposeful activity to carry out, by doing so he acquires principles, skills, and methods. Thus the learner obtain knowledge by experiences gained from tasks and activities.

Al FARABI EDUCATIONAL PHILOSOPHY


Image result for al farabi educational philosophy"

 Al farabi is considered one of the largest Muslim philosophers, and his contemporaries called him “ the second teacher ’’ because of his great interest in work of Aristotle “ the first teacher ’’ , and its interpretation. One of his characteristics is that he tried to reconcile between the philosophy of Aristotle and that of Plato from one hand, and between religion and philosophy from the other hand. (http://www.mawhopon.net/?p=4333). Regarding education, he considered it as one of the most important  social phenomena. The aim of this education to prepare individuals into perfection since they are prepared to this. He combined learning with practical action and he considered that applications are important to understand ideas. Al farabi considered that the teacher should have a good character and seeks truth in all conditions. For educating the people, virtuous people shall be employed and trained in the logical arts. In his opinion. The teaching profession should be adopted voluntarily without any obligation and should be able to demonstrate.  (Rauf, Ahmad, & Iqbal, 2013)
Al farabi was the first Muslim philosopher who classified the sciences and learning. For al farabi, learning must start with the languages and its structures. The foundation for all other kinds of knowledge is because of mastery of common language. Al farabi was well aware of importance of language. Next to language comes logic, which is the instrument of sciences and their methodology. It gives sound reflection to science. It is also closely related to language. The Arabic word for” logic’’ is mantiq which include the verbal expression of intellectual process. This is why, in al- Farabi’s opinion, language comes before rules to enrich the mind. (Rauf, Ahmad, & Iqbal, 2013)

Going beyond the ABC song: Music that Naturally Supports Children's Language Development


                                Image result for musical notes

This evening, i watched a webinar titled as Going beyond the ABC song.This webinar highlights the importance of music and how it affects learning. Its objective was to connect between language learning and music. It demonstrated several kinds of songs that benefit language learning. Some songs enhance the knowledge of vocabulary and spelling. As the children sings with the teacher, they try to imitate the teacher by repeating the words of the song so they learn as they sing. Others support narrative story telling and rhythmic sounds.These songs contain short stories that are told through a song with rhymes. As they sing, they start to acknowledge similar sounds rhyming together. Also they develop the awareness of story telling- in case it sung with book- and print awareness and motivation. In addition, some songs contain "tongue-twister"that help in the learning process. They are repetition of sound-letter associations that enhance vocabulary development, articulation of muscles, active listening, coordination of breathe, of speech, and fun with sounds. while singing, repeating tongue twisters make the children use all muscles in the mouth. Combined with rhymes they learn to use active listening to coordinate between breathe and speech and thus having fun with sounds.

Finally, music learning supports and encourage social and emotional learning. its important to add music to learning since it helps self control, learn math skills by training brains, and the most important thing is that it help kids getting excited about learning.
