Jim,

1. GA has only been found to increase fruit size in a few species such as 
grapes. If it was applied foliarly to pumpkins, it would only cause an 
increase in the rate of stem elongation (vine and petiole elongation). It 
has also been found to increase the number of female flowers in cucurbit 
species.

2. Chemical companies such as Sigma.
