Title
Control of the cocoa pod borer (Conopomorpha cramerella) with Lambdacyhalothrin.
C K Ngim; Shiaw Hooi Ho 1990
Other claims from this paper (9)
- Intervention effect Lambdacyhalothrin was effective against cocoa pod borer in trials.
- Intervention effect Fortnightly lambdacyhalothrin spray at 14-25 ppm significantly reduced cocoa pod borer damage.
- Intervention effect Direct cocoa crop loss was significantly lower than untreated control after six or seven insecticide rounds.
- Intervention effect Five mistblower rounds of lambdacyhalothrin protected the subsequent cocoa peak crop.
- Observation Under that treatment, cocoa pod infestation was below 20 percent.
- Observation Under that treatment, direct cocoa crop loss was well below 5 percent.
- Observation Pod infestation differed greatly between trunk and branch pods on tall unpruned cocoa bushes.
- Intervention effect Adding insecticide further reduced the cocoa pod infestation differential.
- Recommendation The authors recommend canopy practices to improve pod removal and spray coverage for pest control.
