e0“In Worcester Pearmain thinning was stimulated by applications of carbaryl over a 4–5 week period from petal fall, the cessation of thinning activity coinciding with the end of the main period of natural fruitlet shedding.”

- Intervention effect Carbaryl thinning was negligible at 0·0028% a.i.
- Intervention effect Carbaryl thinning rose rapidly between 0·0083% and 0·075%.
- Intervention effect Increasing carbaryl concentration beyond 0·075% added little thinning.
- Association Thinning intensity was greatest at petal fall and declined with later carbaryl application.
- Observation Two 7–13 day intervals interrupted the decline in thinning intensity, during which it stayed relatively constant.
- Observation Induced fruitlet shedding began up to 12 days after carbaryl application.
- Intervention effect Carbaryl thinned within rather than between fruitlet clusters.
- Intervention effect Carbaryl stimulated lateral fruitlet abscission more than terminal fruitlet abscission.
- Intervention effect Carbaryl briefly retarded young fruitlet growth.
- Intervention effect Thinning increased mature fruit size.
- Intervention effect In the year after carbaryl treatment, increased blossom was most marked in biennial Laxton’s Superb trees.
- Intervention effect In the year after treatment, increased cropping was most marked in biennial Laxton’s Superb trees.
- Intervention effect In regularly cropping Worcester Pearmain, thinning moderately increased subsequent blossom.
- Intervention effect In regularly cropping Worcester Pearmain, thinning had no detected residual cropping effect.
