Performance of PDKV Bacillus thuringiensis formulations against green semilooper Chrysodeixis acuta on soybean

The present investigation entitled “Performance OF PDKV Bacillus thuringiensis formulations against Green Semilooper Chrysodeixis acuta on Soybean” was carried out during the year 2024-2025 in the Department of Entomology, Post Graduate Institute, Dr. Panjabrao Deshmukh Krishi Vidyapeeth Akola. The results were found to be statistically significant. However, numerically minimum cumulative mean of larvae of semilooper was recorded after three spraying in descending order of their efficacy in treatment of (T12) PDKV-SGd-1 (75%SC) (1.29/mrl), (T11) PDKV-SGd-1 (25%WP) (1.31/mrl), (T14) PDKV-SGn-4 (75%SC) (1.35/mrl), (T22) PDKV-SY-4 (75%SC) (1.35/mrl), (T20) PDKV-I-3 (75% SC) (1.36/mrl), (T16) PDKV-SGn-6 (75%SC) (1.37/mrl), (T6) PDKV-SA-20 (75% SC) (1.38/mrl), (T10) PDKV-SAK-9 (75%SC) (1.38/mrl), (T21) PDKV-SY-4 (25% WP) (1.38/mrl), (T3) PDKV-SA-18 (25%WP) (1.42/mrl), (T9) PDKV-SAK-9 (25%WP) (1.42/mrl), (T15) PDKV-SGn-6 (25%WP) (1.42/mrl), (T19) PDKV-I-3 (25%WP) (1.42/mrl), (T23) Delfin WG (1.42/mrl), (T17) PDKV-SBn-2 (25%WP) (1.45/mrl), (T5) PDKV-SA-20 (25% WP) (1.48/mrl), (T18) PDKV-SBn-2 (75%SC) (1.52/mrl), (T4) PDKV-SA-18 (75%SC) (1.58/mrl), (T2) PDKV-SA-6 (75%SC) (1.60/mrl), (T13) PDKV-SGn-4 (25% WP) (1.60/mrl), (T1) PDKV-SA-6 (25% WP) (1.62/mrl), (T8) PDKV-SAK-6 (75%SC) (1.67/mrl) and were proved to be effective in controlling the semilooper.
