ratio
The results are in line the findings of Sarlach & Kaur (2013) and Singh et al. (2018) who
observed reduced incidence of para wilt after application of 10 ppm cobalt chloride in cotton.
Results are in line with Sarlach et.al (2008) who observed that foliar application of ethylene
inhibitor (Cobalt chloride 10 μg mL -1 during 36-48 hrs.) after irrigation helped in complete
recovery from parawilt within 5-7 days of spray. However, there was no recovery when
permanent wilting has already set in.
Conclusion
Owing to better results in the demonstration of climate resilient interventions, their adoption
percent increased among the farmers with time and presently hundreds of farmers in NICRA
village and nearby villages having similar agro-ecological conditions are practicing these
interventions.
