Abstract:
Groundnut (Arachis hypogaea L.) is one of the principal oilseeds and food crops of the world. Groundnut suffers from many diseases among them early (Cercospora arachidicola Hori.) and late leaf spot [Phaeoisariopsis personata (Berk. and M. A. Curtis) Arx.] is most widely distributed and economically important foliar diseases of groundnut causing severe damage to the crop. An experiment was conducted for management of early and late leaf spot disease. Out of sevan fungicidal sprays, First spray of the fungicides was done immediately after the initial appearance of disease symptoms and control plot was sprayed by water. The minimum disease intensity was recorded by tebuconazole 50% + trifloxystrobin 25% at 0.05% (26.53%) followed by spraying of carbendazim 12% + mancozeb 63% at 0.15% (31.83%) in checking the leaf spot of groundnut. The maximum disease intensity (55.96%) was recorded in untreated control during both the Years individuals as well as polled also. The economics of spraying of different fungicides revealed that the highest incremental cost: benefit ratio (ICBR) was obtained by three spraying of carbendazim 12% + mancozeb 63% at 0.15%, followed by Hexaconazole 5% at 0.005% (1:10.00).
