Peanut Stripe

 

 

General

• PStV is seed transmitted as well as trasmitted by aphids (Aphis craccivora, A. gossypii and Myzus persicae)

 

 Symptoms

• Symptoms vary, depending on the virus types (isolates) and groundnut cultivar.

• Stripes appear in stripe isolate and groundnut cultivar.

• Stripe isolates cause severe yield reductions. Mild mottles and blotches appear in the other isolates.

Managenent:

1. Production and distribution of virus-free seed should be given a high priority.
   

2. Selection of large seeds for sowing could reduce the source of prmary inoculum and this decreses the incidence of disease.
   

3. Control vectors (Aphids) with Dimethoate @1ml/lt of water.
