A plant growth regulator for the improvement of fruit size in oranges and mandarins.

Active Ingredient: 25g/L Dichlorprop-p
Formulation: Emulsifiable concentrate

  • An innovative crop management tool to increase the marketable yield of citrus trees.
  • Increases the proportion of large, high value fruit at harvest.
  • Registered for use on oranges and mandarins.


How does it work?

Corasil is a plant growth regulator for oranges and mandarins. When applied at the correct time Corasil will increase fruit size by 2-3mm in diameter, delivering more premium grade fruit, increased yield and return on investment.


Mode of Action

The active constituent in Corasil is dichlorprop-P, an auxin based growth regulator. The product mimics a group of natural plant hormones known as auxins and increases fruit size by causing an increase in the size of locules and juice vesicles in fruit.


Increased Fruit Size

In field trials conducted by Nufarm, local industry groups and research organisations, Corasil has increased fruit size and as a result significantly improved pack-out performance.


Other Benefits

  • Earlier harvest may occur which has the potential to attract higher prices
  • Rind colour may be improved however Corasil does not increase rind thickness
  • Corasil may increase stalk strength by increasing the thickness of stalks making them less likely to abcise
