Management of mungbean yellow mosaic virus in urdbean. Management of mungbean yellow mosaic virus in urdbean through chemical and host plant resistance

      Аннотация: Urdbean (Vigna mungo (L.) Hepper) is an important pulse crop grown worldwide. MYMV is an important disease of urdbean and causes huge losses. The urdbean crop can be protected by seed treatment with imidacloprid 17.8 SL @ 5 ml/kg seed along with two foliar spray with imidacloprid 17.8 SL @ 0.03%, which recorded 24.73 % disease reduction over control and brought out significant increase in the growth and yield parameters assessed resulted in maximum seed yield (2.68 g per plant). This treatment found to be cost effective and profitable among all other treatments tested and recorded highest net returns with ICBR of 1:11.40. To combat this disease, eighty two urdbean genotypes were screened against MYMV. Four genotypes i.e. VBN (BG) 7, IPU 2-43, KUG 586, & KUG 503 were found to be superior for seed yield as well as resistant to MYMV.
