Other claims from this paper (19)
- Observation HPLC detected 14 phenolic and flavonoid compounds in Calotropis procera leaves, some with insecticidal effects.
- Observation The C. procera extract had an LC90 of 709.7 µg/mL on Myzus persicae.
- Intervention effect In location 1 the treatment PE + Bb gave an aphid reduction rate of 100% on pepper.
- Intervention effect In location 1 the treatment PE + Ma gave an aphid reduction rate of 97.47% on pepper.
- Intervention effect In location 1 the treatment pesticide gave an aphid reduction rate of 95.53% on pepper.
- Intervention effect In location 1 the treatment Bb gave an aphid reduction rate of 87.83% on pepper.
- Intervention effect In location 1 the treatment PE gave an aphid reduction rate of 81.29% on pepper.
- Intervention effect In location 1 the treatment Ma gave an aphid reduction rate of 75.98% on pepper.
- Intervention effect In location 2 the PE + Bb treatment gave a reduction rate of 96.1% (aphids, pepper).
- Intervention effect In location 2 the pesticide treatment gave a reduction rate of 93.4% (aphids, pepper).
- Intervention effect PE + Ma gave a reduction rate of 86.4%, significantly lower than PE + Bb and pesticide but higher than PE alone (78.23%).
- Intervention effect A similar trend was recorded for whitefly, with a reduction of 96% for PE + Bb and pesticide.
- Intervention effect Whitefly reduction for Bb, PE and PE + Ma was 86-88%.
- Intervention effect Ma gave the lowest whitefly reduction rate, 77.48%.
- Intervention effect In location 2 whitefly reduction reached 100% for PE + Bb, PE + Ma and pesticide.
- Intervention effect In location 2 Bb gave a whitefly reduction of 96.11%, with significant differences from other treatments.
- Intervention effect In location 2 PE (87.98%) and Ma (89.76%) gave lower whitefly reduction with no significant difference between them.
- Intervention effect Commercial entomopathogenic fungi, especially B. bassiana, combined with C. procera leaf extract gave higher reduction rates of aphids and whiteflies than either used alone.
- Recommendation The fungus and plant extract could be used together in integrated pest management of piercing sucking insect pests on pepper.
