🌸🌈INTRODUCTION 🌸🌈

We are student from Politeknik Jeli,Kelantan. Our group member's name are Nurmawardah, Nur Aisyhah Syaheerah and Siti Nurfarah. We are now in semester 2 which is we have a task to identify the problem of durian from subject E-Agricultural. We studies in Diploma Agrotechnology. Our lecturer name is Abdul malek bin A manap. We hope that all of you can learn or get some information in our blog 👀❤.

🌸INTRODUCTION OF DURIAN🌸

The durian (/ˈdjʊəriən/) or /ˈdʊriən/) is the fruit of several tree species belonging to the genus Durio. There are 30 recognized Durio species, at least nine of which produce edible fruit, and over 300 named varieties in Thailand, 102 in Indonesia, and 100 in Malaysia. Durio zibethinus is the only species available in the international market: other species are sold in their local regions. Regarded by many people in Southeast Asia as the "king of fruits", the durian is distinctive for its large size, strong odour, and formidable thorn-covered rind. The fruit can grow as large as 30 centimetres (12 in) long and 15 centimetres (6 in) in diameter, and it typically weighs one to three kilograms (2 to 7 lb). Its shape ranges from oblong to round, the colour of its husk green to brown, and its flesh pale yellow to red, depending on the species. Some people regard the durian as having a pleasantly sweet fragrance, whereas others find the aroma overpowering with an unpleasant odour. The smell evokes reactions from deep appreciation to intense disgust, and has been described variously as rotten onions, turpentine, and raw sewage. The persistence of its odour, which may linger for several days, has led to the fruit's banishment from certain hotels and public transportation in southeast Asia. By contrast, the nineteenth-century British naturalist, Alfred Russel Wallace, described its flesh as "a rich custard highly flavored with almonds". The flesh can be consumed at various stages of ripeness, and it is used to flavor a wide variety of savory and sweet desserts in southeast Asian cuisines. The seeds can also be eaten when cooked.

THIS VIDEO ARE FROM OUR GROUP INTERVIEW SIR WONG SOON THEAM AT 142 MK 2 SG. PINANG 11010 BALIK PULAU. WE LIKE TO IDENTIFY THE DISEASE OF DURIAN BECAUSE WE WANT TO PREVENT DISEASE OF DURIAN. 

FOLIAGE DISEASE 😯

Subject to various pests and diseases throughout the year .this article discuss about durian foliage disease mostly found in Malaysia. Durian disease divided to seedling and root disease, trunk and branch disease, foliage disease and fruit disease. Total production of durian estimate about 297,700 metric tonnes annually. However, about 15,000 mt of durian import from Thailand annually  for domestic market mostly during of season. I would like to share my knowledge about durian disease base on various study in Malaysia, Thailand< Indonesia and other growing durian countries.

💣Canker Branch Disease💣          

This disease is caused by a fungus called Phytophthora palmivora. It causes canker branch, rotting of root, seedling’s death, and rotten fruit. Canker branch is the most serious of all durian diseases. It usually targets trees which are starting to produce fruit. This fungus destroys the bark of the tree resulting in leaf-shedding and then causes the tree to die. Patch Canker of durian or known as Stem Canker together with root rot and dieback are serius disease of durian. The main cause of this disease are Phythopthora palmivora. The first sypmtom of this disease is the appearance of of wet lession on the trunk surface usually near the crotch region. Bark necrosis is accompanied by discoloration of the bark and exudation of  a reddish brown resinuos substances. The infection sometimes deep into the wood and when we knocked with hard object it sounds hollow. As the lesion expands, I always saw the tree exhibits the sign of stress with the foliage wilt and began to dry up followed by branch dieback. The entire tree may defoliate and die where the entire bark become riddled with pin-holed made by pin-bole boring beetle (Platipus capulatus). The root underground infected with necrosis and decayed. This disease are the mos serious disease of durian tree and must use a multi-pronged approach to control. The combination of various chemical, environmental and biological measure should apply.

💣Hawar daun Rizoctonia💣  

This disease causes leaves to shed during the rainy season.After attacking the leaf, this fungus will then spread to the whole tree.

💣Termite💣

Termites that have been reported to attack durian trees are Microtermes pallidus. Termites can cause a bigger problem if they attack a young durian tree. During that period, the termite attacks the roots. This later kills the tree.

💣Platypus Beetle💣

This insect usually attacks a tree without any early sign. It usually attacks an adult tree.

💣Worms💣

(Left) A Mudaria worm. (Right) The Mudaria larva, pupa and moth.

Worms that attack branches, twigs and stems are Batocera gultala and Zeuzera coffeae. The parts that are affected by these worms must be pruned. Worms that attack the fruits are Mudaria magniplaga, Conogethes puncliferalis and Tonick terracella.

💣Teritip💣

 

Twigs and leaves attacked by teritip

Teritip that attacks durians are identified as Pectenococus. Trees that are affected will look pale. They will then dry up and die.

💣Koya(Mealy bugs)💣

A durian(right) attacked by koya.

Koya is a kind of white insect that attacks the flower, leaf and fruit. The insect does not cause damage but it makes the durian look as if it has been infected by disease. Koya emit a kind of sweet substance that encourages the growth of sooty mould.

💣Squirrel💣

A durian attacked by squirrel.

💣Monkey💣

Monkeys do not cause damage to the tree or the fruit but they tend to make durians fall for the fun of it. These durians are usually unripe ones.

💣White Flea💣

White fleas pests (Psendococus sp.) are rounded greenish and the growth is covered by a layer of wax slightly whitish. This flea attacks the durian plants by sucking leaf fluids, this pest also attacks soot dew. Her sweet cravings invites the ants so that her followers follow the ants. Flowers and fruit can suffer from bleeding eruptions at the same time with shoot dew and ants that become the means of eradication can use insecticides and acarisides.

CONCLUSION 💡💡

So as a conclusion, we know that the Durian have many problem in pest and diseases. The farmers can control to reducing attacks from diseases and pests. Farmers can identify the problem early and can curb durian trees from getting pest infestation.  From the report we know the use of internet to increase the yield of agrotechnology. Besides we can use the blog as an advantage to promote our product to public just not using the old way .
