Management Of Pre And Post Harvest Fruit Rot Diseases Of Ber

Abstract

The main focus of this research is to produce the good quality and disease free fruits. In this aspect, the investigation was carried out to reduce or control the pre and post-harvest fungal fruit rot. The study on pre and post-harvest management of fruit rot diseases of ber caused by Alternaria and Colletotrichum was carried out and the results showed that two pre-harvest sprays of Thiophanate Methyl (0.1 %) at 15 day intervals during the marble stage of ber fruit was found effective against Alternaria fruit rot recorded 6.8 PDI compared to untreated control recorded 43.6 PDI. Two pre-harvest sprays of 0.1 per-cent carbendazim at 15 day intervals was found effective against Colletotrichum fruit rot during the pea fruit stage of ber recorded 6.6 PDI compared to untreated control recorded 44.2 PDI. The post-harvest studies revealed that dipping of ber fruits in 2 per cent sodium chloride solution for 10 min. recorded the lowest PDI of 5.27 against post-harvest fungal rot as compared to untreated control recorded 25.27 PDI.
