Phytophthora infestans is an oomycete that causes the serious potato disease known as late blight or potato blight. (Early blight, caused by Alternaria solani, is also often called "potato blight".) Late blight was a major culprit in the 1840s European, the 1845 Irish and 1846 Highland potato famines. The organism can also infect tomatoes and some other members of the Solanaceae. At first, the spots are gray-green and water-soaked, but they soon enlarge and turn dark brown and firm, with a rough surface. This year due to higher temperature on day time, Fog, and excess humidity weather was unfriendly potato plants. So that plant has contaminated by Phytophthora infestans on early stage. Moreover uncertain precipitation influence rapid contamination of disease. As we do not have any higher combined fungicide as like “200 g/lazoxystrobin 125 g/ ldifenoconazole” I have made a new combination by using our product 6.25 g /Mancozeb 3.20 g/ Metalayxyle 1.28 g/Iprodion . It means Maxgold 4gms + Ipron 1.56 gms per litter of water. The combined solution of chemicals has protect potato plant from Phytophthora infestans. On the basis of the field demonstration we can say that, the combination of 6.25 g /Mancozeb 3.20 g/ Metalayxyle 1.28 g/Iprodion can prevent and cure Phytophthora infestans

Technical report on “Efficacy of Ipron and Max gold on Phytophthora infestans”
Dear Sir,
Respectfully I would like to let you know that this year above mentioned two products are performing an
effective role in order to protect plant from Phytophthora infestans. I have conduct several demonstrations
on early and let potato breed. Early breed has already harvested and let breeds are under control from blight.
Here I am submitting the technical report of above mentioned subject for your kind consideration.
Introduction: Phytophthora infestans is an oomycete that causes the serious potato disease known as
late blight or potato blight. (Early blight, caused by Alternaria solani, is also often called "potato blight".)
Late blight was a major culprit in the 1840s European, the 1845 Irish and 1846 Highland potato famines.
The organism can also infect tomatoes and some other members of the Solanaceae. At first, the spots are
gray-green and water-soaked, but they soon enlarge and turn dark brown and firm, with a rough surface.
This year due to higher temperature on day time, Fog, and excess humidity weather was unfriendly potato
plants. So that plant has contaminated by Phytophthora infestans on early stage. Moreover uncertain
precipitation influence rapid contamination of disease.
Chemical Combination: As we do not have any higher combined fungicide as like “200 g/lazoxystrobin
125 g/ ldifenoconazole” I have made a new combination by using our product 6.25 g /Mancozeb 3.20 g/
Metalayxyle 1.28 g/Iprodion . It means Maxgold 4gms + Ipron 1.56 gms per litter of water. The combined
solution of chemicals has protect potato plant from Phytophthora infestans.

3. Result dissociation:

Before Application
After precipitation the potato plant
was highly infected. It this image
we can see the leaf has rooted and
spore of the pathogen has
developed (Whitish Mold)
Image -2
After Application
After application of mentioned
chemicals solution infected area
has dried. Infection dose not
spayed out.

Disease prevention
The combined chemicals create a
protective stick layer on outer leaf.
The protective layer has covered
stomata (Microscopic leaf cave) so
that fungi’s spore ware unable to
enter.

Crop Recovery
After spraying three times (5 days
interval) the crop has saved from
Let blight not only that we did not
get any single sign of Early blight
on this field.

5. Hypothesis:
On the basis of the field demonstration we can say that, the combination of 6.25 g /Mancozeb 3.20 g/
Metalayxyle 1.28 g/Iprodion can prevent and cure Phytophthora infestans.
Recommendations:
Ned to conduct huge promotional activities in order to promote the product.
Product weight of each packet shall be same as mentioned weight of packet.
