  Cowpea Mosaic        Casual organism: cowpea aphid borne mosaic virus Symptoms:first appears dark and light green patches  on leaf surface area.When the disease advances leaf become yellow and dry up.Affected plants have prominent leaf vein,smaller young leaves,stunted plant growth and distorted fruit.Aphid,whiteflies and thrips can transmit viruses from plant to plant on which they feed.Aphid feeding may cause the leaves and fruit to become distorted.Thrips cause severe damage to the young crop by sucking the           cellsap.Whiteflies also feeds on the under surface of the leaf.Disease will transmit through seeds having viruses . Control measures:No adequate control for mosaic disease only we can control vector transmission. *Use only healthy seeds *Spray malathion50EC@2ml/litre or Quinalphose25EC@1.25ml/litre *Spray botanicals like nee oil emulsion *Place yellow sticky trap in fields.

Banana Banana is growing in more than 150 countries and having more than 1000types which subdivided into 50 groups. It is a staple food for many countries and has a greater value in nutritional aspects Kerala is bestowed with many varieties of Banana. My search ends with more than fifty varieties of Bananas including all groups. Here I am finding the evolutionary history of two important crops called Banana and coconut. But both belong to different Genus. It is very difficult to find the traces of similarities to two crops and maybe unnecessary to the academics. The evolution of plants always a fascinating subject to me. I believe the evolution of plants happens from one plant to another. So I studied the following characteristics of two crops.

Bananas globally rank fourth in the position after rice, wheat, and maize as food for human. They are grown in more than 130 countries worldwide.  Bananas are native to tropical southeastern Asia but are widely cultivated in the tropical region of other parts of the world. Banana is a herbaceous flowering plant arising from the underground rhizome.               Now the UN Food and Agriculture Organization (FAO) has warned that wild banana species are rapidly going extinct as Indian forests are destroyed while many farmers varieties are also disappearing from the fields. So it is very urgent to take a global effort to save the banana's gene pool                               The majority of cultivated bananas arose from the Eumusa group of species. This section is the biggest in the gen
