Efficacy of neem products and insecticides for the control of shoot fly Formosina flavipes Mall. of Cardamom (Elettaria Cardamomum Maton.).
Experiments were conducted at Zonal Agricultural Research Station, Mudigere, India, for two years with an objective to study the population fluctuation, seasonal incidence and evaluation of neem products and insecticides for their efficacy against cardamom shoot fly. During the study period, it was noticed that shoot fly population the increased during the dry months (March, May and October) but was low from June to September months. The population exhibited a negative correlation with rainfall, minimum temperature and maximum relative humidity and positive correlations with maximum temperature and sunshine h. Among the six insecticides tested, phorate, phorate with neem cake and neem cake alone were found superior over other treatments. The present study clearly indicated that application of neem cake helps not only in reduction of shoot fly incidence but also enhances the production of side suckers compared to other treatments.
