ABSTRACT

Grey mould of grapes (Vitis vinifera L var. red globe) caused by Botrytis cinerea Pers. ex. Fr. is recorded as an economically serious pathogen found in stored and imported grapes in India and which may cause heavy loss in all grape producing countries. Therefore the management of grey mould is equally important. In conventional agriculture the application of fungicides to grapes after harvest to reduce decay has been increasingly, curtailed by the development of pathogen resistance, the lack of knowledge of fungicide, negative public approach regarding the safety of pesticides and consequent restrictions on fungicide use. The study of alternative methods to control of grey mould decay has developed over several decades. Twenty five isolates of B.cinerea were isolated from infected samples of grape collected from various localities of Maharashtra. Out of which isolate Bc-19 was highly sensitive (290.8 mg/ml) while isolate Bc-11 was resistant (1095.1 mg/ml). Sensitivity of B. cinerea was tested using thiophanate methyl by food poisoning methods. Experiments were performed in Research Laboratory, KVP to find out the natural and safe alternative method to control of resistant Bc-11. Six fungicides viz. dithane M-45, thiram, zineb, benomyl, carbendazim and captafol were used individually and in mixture with thiophanate methyl. Benomyl gave a significant PCE individual at 50 碌g/ml (70.01) and at 100 碌g/ml PCE value (83.12) when compared with thiophanate methyl at 100 碌g/ml (58.12), Captafal 50 碌g/ml and 100 碌g/ml (64.18), zineb 50 碌g/ml (62.13) and 100 碌g/ml (75.15) PCE values, thiram at 50 碌g/ml (54.12) and 100 碌g/ml (PCE- 65.10) and dithane M-45 at 50 碌g/ml PCE (38.02) and 100 碌g/ml (48.15) PCE values. Dithane and thiram was less effective. Trichoderma viride was found to be the most effective in reducing the colony diameter of B. cinerea (69.89 - 68.12). Thus T. viride proves better and safe for the management of B. cinerea of grape as a biocontrol agent.
