Abstract

Coriander (Coriandrum sativum L., 2n=22) is a vital herb extensively used for culinary and medicinal purposes. However, its cultivation is significantly impacted by leaf blight caused by Alternaria alternata (Fr.) Keissler. This study aims to investigate the effectiveness of various management strategies to control coriander leaf blight. Specifically, it investigates the efficacy of different phytoextracts and cow-based products were evaluated against A. alternata under in vitro and in vivo conditions. Among phytoextracts tested under in vitro condition, Allium sativum at 10 per cent concentration showed the maximum mycelial growth inhibition (65.23%). In the case of cow-based products, the maximum mycelial growth inhibition (88.56%) was observed in Panchagavya at 60 per cent concentration. To validate the efficacy of phytoextracts and cow-based products, a trial was also conducted under field conditions. The results showed that foliar application of Panchagavya was significantly superior over the rest of the treatments and showed minimum disease intensity (10.55%) at 60 per cent concentration with 84.16 per cent disease control. Looking to the yield, the treatment Panchagavya at 60 per cent gave maximum seed yield (1406 kg/ha) with 86.21 per cent yield increased over control. The effective phytoextracts and cow-based products discovered in this study can be incorporated into an integrated disease management approach for A. alternata in coriander

Conclusion

Leaf blight caused by Alternaria alternata (Fr.) Keissler poses a significant threat to coriander crops. From our investigations, it is evident that among the tested phytoextracts, Allium sativum at 10 per cent concentration showed the maximum 65.23 per cent mycelial growth inhibition. Similarly, among different cow-based products evaluated, Panchagavya at 60 per cent concentration showed the maximum 88.56 per cent mycelial growth inhibition. In field conditions, Panchagavya at 60 per cent concentration was significantly superior over the rest of the treatments and showed minimum disease intensity (10.55%) with 84.16 per cent disease control
