abstract
Chilli (Capsicum annuum L.) is native to the Mexican region, an inevitable part of the Indian culinary world and renowned for its medicinal uses, and India is the world's leading chili grower and exporter. The present investigation was carried out at the Institute of Agricultural Sciences, Banaras Hindu University, vegetable research farm, Varanasi to study “management of major sucking pests of chilli (Capsicum annuum L.) with newer combination product”. Mite infestation started from first week of December and the peak was observed during the last week of December, mites showed a negative but significant correlation with maximum and minimum temperature and there was a positive non-significant correlation between mite population and relative humidity (morning and evening) and wind, there was negative non-significant correlation between rainfall and the population of mite. The newer molecules used to determine bio-efficacy of mite are spirotetramat, fenpropathrin and diafenthiuron along with combination of spirotetramat + diafenthiuron in different doses, it was observed that (spirotetramat 30g/l +diafenthiuron 120 g/l w/v SC) @ (75+300) g a.i./ha, gave an overall per cent population reduction of 65.06% in mites. Along with bio-efficacy of insecticide, its yield treatment wise found that the plot treated with spirotetramat + diafenthiuron @ (75+300) g a.i./ha gave maximum yield 4.35 tonnes/ha and about 39.04% increase in yield compared to untreated plot. Such combination products can fit into the insect pest management programme of chilli.
