1-aminocyclopropane carboxylic acid as a fruit thinner
View Patent ↗The present invention relates to agricultural methods and compositions of 1-aminocyclopropane carboxylic acid (ACC) alone or in combination with 2-chloroethylphosphonic acid (ethephon) to reduce crop load of fruit trees.
1. A method to reduce crop load by inducing ethylene production comprising applying 100 to 1000 ppm 1-aminocyclopropane carboxylic acid to stone fruit or pome fruit trees during bloom or at the fruitlet stage.
2. A method of reducing crop load of trees by inducing ethylene production comprising foliar applications of 100 to 1000 ppm 1-aminocyclopropane carboxylic acid during bloom or at the fruitlet stage.
3. The method of claim 1 wherein the stone fruit trees are peach trees.
4. The method of claim 1 wherein the stone fruit trees are nectarine trees.
5. A method to reduce crop load by inducing ethylene production comprising applying 100 to 1000 ppm 1-aminocyclopropane carboxylic acid to apple trees during bloom or at the fruitlet stage.
