Climate change is not just the increasing temperature, snow melting its more than that. |

Climate change: increasing temperature, melting snow caps and glacier, global warming, greenhouse effect. Here I got an interesting topic to discuss. Grey leaf spot of maize: also known as climate change disease by the pathologists of the agriculture. This disease is cause by the cercospora zea maydis. Symptoms seen on corn include leaf lesions, discoloration (chlorosis), and foliar blight. The fungus survives in debris of topsoil and infects healthy crop via asexual spores called conidia. Environmental conditions that best suit infection and growth include moist, humid, and warm climates. Poor airflow, low sunlight, overcrowding, improper soil nutrient and irrigation management, and poor soil drainage can all contribute to the propagation of the disease. A reason for this disease to call climate change disease, few years back this disease was not a matter of concern in the Nepal but with increasing temperature now this disease has taken the epidemic in the mid hills of Nepal. This disease appears on the shrawan after the initiation of monsoon and with leaf wetness and increased temperature takes epidemic form and devastating damage in the maize. Along with new disease there is back ward motivation of disease like Bunt which has seen poorly with increasing temperature and seen poorly. Climate change has not only affected the just the air, temperature or snow caps its more than that. |

Another hazardous effect of climate change. It is very horrible. I want to ask, so far is there any solution or treatment for plants who has grey leaf spot of maize?

This is really grim situation, Sabin, well reported. Climate change is a serious threat. Hope to find a viable solution ASAP.

The effect of climate change is unimaginable. If we think throughly we can find out how everything in this worl is interlinked and how warming up of the climate change has devastated life of many people, decreased the yield of crops and deteriorated human and Animal health along with increasing in the aa tack by pest and diseases.
So we must take action, start from ourselves and inspire other too.
Thanks for the report with the picture Subin bro 😊. We need to bring the issues you have raised in the lime light

There is no doubt that climate change is posing serious threats to all forms of life including spoiling the crops , increasing the diseases vulnerability. Thanks for throwing light on climate change impact on plant diseases incidence.

Dear friend Sabin, I am glad to see your report about Grey leaf spot of maize which is a consequence of climate change. Agriculture is one of the prime area to get affected with climate change include shift in cropping patterns, evolving new diseases or existing in more prominent form, reproductive failures, stress in livestock and so on. (Just a suggestion- Had you said July/ August month instead of Shrawan as we are Global family :) ) Keep on writing dear :)

Thank you for coming up with an important issue, Sabin. Here in Korea, similar problem is changing the geography of agriculture in Korea. Also the forest is changing. Pine trees are endangered to extinction because of disease caused by climate change.
