Evaluating Compatibility of Pulse Wonder with Insecticides and Fungicides in Greengram

A field experiment was conducted in greengram to evaluate the compatibility of pulse wonder with insecticides and fungicides. A total of 9 treatments were tested to study the phytotoxic effects of combination of pulse wonder with insecticides and fungicides. The treatments include, five insecticides (Imidachlorprid @ 0.1% (For sucking pest), Chlorpyriphos @ 0.25% (Foliage feeder), Chlorantriniprole @ 100 ml/acre (For pod borer) and 2 fungicides viz., Mancozeb 0.2% (For fungal disease), Copper oxy chloride 0.25% (For bacterial disease) and their 7 combinations along with untreated control. Also tested in combination with fungicides viz.,Mancozeb 0.2% (For fungal disease) and Copper oxy chloride 0.25% (For bacterial disease). Laboratory experiment was also conducted to evaluate the physical compatibility. Physical compatibility test was conducted prior to field study to observe changes in colour, wettability etc., Among 7 combinations of pulse wonder with insecticides and fungicides tested neither foaming nor sedimentation was observed in all 7 combinations of pulse wonder with insecticides and fungicides tested and found to be physically compatible. As the foaming and sedimentation was lower than the prescribed limit (2ml/100ml or 20ml/l), all the combinations of pulse wonder with insecticides and fungicides tested were found to be physically compatible. In the field experiment pulse wonder alone improves the plant growth, flower production, pod number and yield. Whereas pulse wonder along with insecticide and pesticide reduces the pest and disease load but not the flower production and pod number.
