Bio-efficacy of indoxacarb 15 EC against pod borer, Helicoverpa armigera (Hubner) hardwick infesting pigeonpea

Front Line Demonstration on foliar application of broad spectrum insecticide Indoxacarb 14.5 SC for control of pod borer, Helicoverpa armigera in green gram was conducted on farmers field in Nagaur district during 2019-20. Through the demonstration of the technology, 35.1% increase in green gram production has been observed with the production of 6.35 q/ha as compared to farmer’s practice (4.7 q/ha). Under demonstrated practices farmer were advised to alternate spray of the given insecticide on appropriate time. Under demonstrated practices, farmers got maximum net return of 21,667 Rs./ha, whereas, it was 12,285 Rs./ha in farmer’s practices.

Weekly larval populations of pod borer, Helicoverpa armigera (Hubner) collected from 20 districts of Maharashtra under Crop Pest Surveillance and Advisory Project (CROPSAP) during 2010-2015 were analyzed to work out the effect of weather variables on the incidence of this insect on soybean. The appearance of larva was observed throughout the soybean growing season, and the peak incidence was observed during third week of August to first week of September (34-35 SMW). The correlation analysis of the data revealed that larval population was significantly and positively influenced by the minimum temperature and rainfall of current week as well as previous two weeks. For the development of forewarning model, data for the period from 2010 to 2013 were used as training dataset and two year (2014-2015) data as validation dataset. The mean model used for forewarning the incidence of pod borer larval population was developed by using step-wise multiple regression analysis in polynomial form. The results of mean model revealed that the significant variables affecting the pod borer larval population in soybean were maximum temperature (current and 1st lag week), and rainfall (current week) and the model explained 48.93% variation. The pre-disposing conditions for the incidence of larvae have been worked out as maximum temperature ranging from 26.1 to 31.47 ºC and rainfall ranging from 6.63 to 141.46 mm with low or medium rainfall in previous weeks followed by high in current week. The model was validated with 2014-15 independent dataset with predicted R2 (R2 ) value 28.13%. Two sample t-test showed no Pred significant difference between observed and predicted values (p = 0.3691 > 0.05).

An experiment was conducted to develop an 1PM approach for the management of pod borer, Helicoverpa armigera (Hubner) in chickpea field. Out of seven modules studied, module 5 consisting of sequential first spray with Helicoverpa nuclear polyhedrosis viruses (HNPV) @ 500 LE/ha and second spray after seven days interval with Cypermethrin @ 1 ml/ litre gave the best protection with the lowest pod borer damage (4.62%) and provided the highest yield (2096 kg/ha) and maximum net return (Tk. 43746/ha) followed by module 3 where only RNPV was sprayed twice. But the most economic module for pod borer management was M2 where chickpea intercropped with mustard was sown on 15 November. For best protection against pod borer, the most effective 1PM module was chickpea sown on 15 November and first spraying with HNPV @ 500 LE/ha just at 100% plant pod formation stage and second spray after 7 days with Cermethrin @ 1 ml/L, ensuring higher yield and return.

Background: Pod borer, Helicoverpa armigera (Hubner) and pod fly, Melanagromyza obtusa (Malloch) are important pod boring insects infesting the pigeonpea, Cajanus cajan (Linn.) Millsp. throughout the world. A number of synthetic insecticides are known to be effective against these borers but most of them have been phased out as a result of high toxicity to the pollinators and other biotic agencies, therefore, a new molecule, chlorantraniliprole has been tested for bioefficacy against these insect pests.Methods: The experiment was conducted during Kharif, 2017 in a Randomized Block Design (RBD) with 7 treatments and 3 replications. Observations were made to record pod borer, H. armigera and pod fly, M. obtusa maggot present before treatment imposition and 3, 7 and 14 days after each spray from five randomly selected and tagged plants/ plot. From the data recorded per cent reduction in population over control was calculated. The per cent pod damage was calculated by counting damaged pods out of healthy pods. The numbers of coccinellids and spiders were recorded on 5 randomly selected plants before treatment and 7 and 14 days after spray (DAS) in each treatment.Result: The chlorantraniliprole 18.5 SC was found most effective @ 200 ml/ha which was found at par with chlorantraniliprole 18.5 SC @ 150 ml/ha and chlorantraniliprole 18.5 SC (Market sample) @ 150 ml/ha for suppression pod borer, H. armigera and pod fly, M. obtusa. The yield was maximum and at par in the chlorantraniliprole 18.5 SC @ 200 ml/ha (18.25 q ha-1), chlorantraniliprole 18.5 SC @ 150 ml/ha (17.82 q ha-1) and chlorantraniliprole 18.5 SC (Market sample) @ 150 ml/ha (17.42 q ha-1). Predatory population of coccinellids and spiders after imposing the treatments declined to some extent at seven days after treatment, however, increased after 14 days. Based on the results, the use of chlorantraniliprole 18.5 SC @ 150 ml/ha was most effective to control pod borer and pod fly in pigeonpea crop.
