Groundnut rosette

Groundnut Rosette


General :

  •  The most destructive virus disease on groundnut in sub-Saharan Africa(SSA).Three casual agents are invoved in GRD such as Groundnut rosette assistor virus (GRAV), Groundnut roselte virus (GRV) and a satellite RNA (satRNA)Trasmitted by an Aphid, aphis craccivora


  • Two symtom variants ,chlorotic rosette and green rosette

  • Both forms of the diseases cause plants to be severely stunted, with shortened internodes and reduced leaf size , resulting in a bushy appeaerance of plants.

  • In chlorotic rosette , leaves are usually bright yellow with a few green islands and leaf lamina is curled.

  • In the green rosette , leaves appear dark green,with light green to dark green mosaic


  1. Destroy virus sources: Remove infected plants after harvest , volunteer plants or that can harbor vector aphids.

  2.  Cultural practices:


  •     Sow early in the rainy season to take advantage of low-aphid population.

  •     Remove and destroy early infected plants and fill the gap.

  •     Maintain optimum plant population in the field, which covers ground thereby discourages landing of vector aphids on the crop.



     3.  Chemical treatment:  Seed  treatment with imidaclorprid and followed by regular systemic insecticide spray in the early stages of the crop growth  ( from emergence to 40th day ) will control vector aphids.



    4. Cultivate resistant variables : Some resistant cultivators available for cultivation in SSA are ICG 12991 ,      ICGV-SM 99568 , ICGV 93437 , ICGV-IS 96894, ICGV-SM 99541
