Abstract:
The field experiment was conducted at Instructional farm of Barrister Thakur Chhedilal College of Agriculture and Research Station, Bilaspur, Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh) during kharif 2022. The studies revealed that the first appearance (7.7 aphid per 10 cm. twig/plant) of Aphid on Black gram was observed during the 32nd standard week in vegetative stage, which continued to build up with intermediately up and downs and reached maximum (13.5 aphid per 10 cm. twig/plant) during second week of September in pod filling stage and observed up to maturity stage of crop. The correlation studies revealed that population of aphid was exhibited significant negative correlation with maximum temperature (r = -0.774) and all other weather parameters were non-significantly correlated with population of aphid.
