Other claims from this paper (9)
- Intervention effect NPA plus Ethrel significantly enhanced pear defoliation.
- Intervention effect Defoliation at 1000 ppm NPA was not superior to 500 ppm.
- Intervention effect In 1992, two applications were generally no better than one.
- Intervention effect In 1993, two applications were often more effective than one.
- Intervention effect Adding Ethrel to NPA generally enhanced defoliation when the combination was applied twice.
- Intervention effect Alanap and NPA were generally equally effective defoliants.
- Intervention effect Ethrel added to Alanap enhanced defoliation in only three of nine cultivars, generally with two sprays.
- Intervention effect Alanap plus Ethrel was as effective at 300 ppm Alanap as at 500 ppm.
- Intervention effect Ethrel by itself seldom increased defoliation.
