(Malhotra Publishing House, 2019) Babli Bagri; N.N. Singh; V.K. Mishra; G.T. Shruthi
The occurrence of aphid populations started during the 2 nd week of January and attained its peaked during the 2nd week of February, 2018 with 117.96 aphid / 10 cm central shoots. The temperature (maximum, minimum) on the observation day was 24.1 and 10.65°C, 83.25% and 48.25% was maximum and minimum relative humidity respectively. Thereafter, the population decline more or less gradually being minimum 1st week of March 2018 recording 0.06 aphid /10 cm central shoots. The correlation between aphid population and temperature (maximum, minimum) showed a negative correlation with 'r' value of -0.4288 and -0.2741, respectively. Whereas a positive correlation with morning relative humidity, a negative correlation with evening relative humidity. The correlation between aphid population and temperature, relative humidity was found statistically non-significant. © 2019 Malhotra Publishing House.
Evaluation of some insecticides and biopesticides for the management of pod bug, Clavigralla gibbosa (Spinola) on long duration pigeonpea
(Malhotra Publishing House, 2023) Babli Bagri; Ram Keval
Study revealed that the acetamiprid 20% SP was found superior and showed minimum pod and grain damage during 2-year trial followed by fipronil 80% WG, azadirachtin 1500 PPM, thiamethoxam 25% WG, Beauveria bassiana 1.15% WP and deltamethrin 2.8% EC. The highest damage due to pod bug was found in Clothianidin 50% WDG treated plot over control. Acetamiprid 20% SP treated plots also showed maximum yield followed by other treatments. © 2023 MPH J ent Res. All Rights Reserved.
