RIGOROUS, A HOMEOPATHIC MEDICINE, EFFECTIVE FOR CONTROLLING APHIDS IN BREAD WHEAT

2 (T2) (Rigorous 1.5% solution @ 1.5 litre + 100 litre of water/acre) revealed minimum aphid population and maximum aphid mortality percentage for all time points. The results showed that aphid population decreased and the mortality rate increased with the passage of time from 24 hour to 7 days. The treatment, T 3(water only) was the least detrimental for the coccinellids predator for all time po ints. There was a positive correlation between aphid population per tiller and number of coccinellids per plant for all durations. Rigorous application resulted in significant increase in grain yield per hectare as compared to control. The results conclude d that Rigorous could be efficiently utilized for controlling aphids in bread wheat in addition to less detrimental effects to the natural enemies of aphids.
