How did Ireland get rid of potato blight?
How did Ireland get rid of potato blight?
However it was not until 1882, almost 40 years after the famine, that scientists discovered a cure for Phytophthora Infestans: a solution of copper sulphate sprayed before the fungus had gained root. At the time of the famine there was nothing that farmers could do to save their crop.
What ended the Irish Potato Famine?
1845 – 1852
How was the Irish Potato Famine solved?
BBC News reports a research team led by The Sainsbury Laboratory in Norwich, England, used dried leaf cuttings — some of which are nearly 170 years old — to reconstruct the spread of the HERB-1 strain of Phytophthora infestans, a fungal disease that came to Ireland via Mexico in 1845.
What did the potato blight look like?
What does potato blight look like? Blight turns the leaves brown and fungal spores develop. Dark brown blotches appear around leaf tips and edges, spreading towards the middle, shrivelling and rotting the leaf.
How do you prevent potato blight?
Store only potatoes in perfect condition and regularly inspect stored potatoes for signs of deterioration. Practice good crop rotation and buy seed potatoes only from certified suppliers as explained earlier. Choose potato varieties which are naturally resistant to potato blight.
What happens if you eat a potato with blight?
Potatoes can become infected both before or after harvest, with the disease appearing as brown, dry and sunken areas. “The unaffected parts probably are safe to eat. “Since there is no documented harm from eating blight-infected fruit, it may be tempting to simply cut off the infected portion.
How do I know if my potatoes have blight?
Blight in potatoes is characterised by a rapidly spreading, watery rot of leaves which soon collapse, shrivel and turn brown. Close up of leaves affected by potato blight. Affected tubers have a reddish-brown decay below the skin, firm at first but soon developing into a soft rot.
Is there a cure for potato blight?
There is no cure for potato blight when your plants are infected. The first action to take is to cut off all growth above soil level and burn it as soon as possible. This will minimise the infection on your soil and also reduce the risk of you passing potato blight on to neighbours and that includes neighbouring farms.
Why did the Irish not eat fish in the famine?

What was the problem with the potato in Ireland?
The potato crop was very vulnerable to disease and no cure existed in Ireland for potato blight. Even if a cure had existed, it would not have been affordable. In 1844, a new form of potato blight was identified in America which turned a potato into a mushy mess that was completely inedible.
What was the name of the disease that killed the potato?
It wasn’t until the early 20th century that improvements in crop breeding yielded potato varieties that proved resistant to HERB-1 that the deadly infection was stopped in its tracks. Scientists believe that the HERB-1 strain is now extinct.
How did the potato blight spread to Europe?
It is now known that the same potato blight struck in the USA in 1843 and 1844 and in Canada in 1844. It is thought that the disease travelled to Europe on trade ships and spread to England and finally to Ireland, striking the south-east first. The picture on the left shows what a blighted potato looks like.

Boston, New York City, Philadelphia and Phoenix in the United States, as well as Montreal and Toronto in Canada, have erected Irish hunger memorials, as have various cities in Ireland, Australia and Great Britain.
What caused potato famine?
The Great Famine was caused by a failure of the potato crop, which many people relied on for most of their nutrition. A disease called late blight destroyed the leaves and edible roots of the potato plants in successive years from 1845 to 1849.
How did the Great Potato Famine affect Ireland?
The famine was caused by “the potato blight”, a fungus-like organism which quickly destroyed the potatoes in Ireland, and throughout Europe. The effect was particularly severe in Ireland because potatoes were the main source of food for most Irish people at the time.
How did Irish Potato Famine affect immigration?
The largest impact the Irish Potato Famine had was the mass migration of Irish people. During the Famine, thousands of Irish emigrated to the United States in hope to find a new life. Many of these immigrants started associating with Irish freedom and liberation groups.
How and why did the Irish Potato Famine end?
The famine mainly ended due to the reduce population from 8 million to 4.5 million by the end of the century either by emigrating or by the Irish dying. By 1852 the potato crop had recovered and could be planted again.
