With the industrialization of agriculture, companies have been testing various methods to increase efficiency and quantity of products (Curry, 2013). A particular method is to decrease the amount of time needed for the desired food product to grow to a harvestable quality. This can be done by using chemicals and hormones to trick plants into growing faster than normal.
Gibberellins are a group naturally occurring hormones that are involved in plant growth (Dar et al., 2015). Gibberellic acid (GA3) is a gibberellin that can be found in most crop plants as it regulates ripening of fruit and shoot growth (Bhattacharyya and Jha, 2012; Narula, et al., 2006). However, agricultural companies provide more than natural occurring amount of gibberellic acid to their plantations. When gibberellic acid is sprayed in the fields, it can contaminate bodies of water through run-off or off target spraying.
It is required by the Federal Insecticide, Fungicide and Rodenticide Act (7 USCS 136, et seq.) and the Toxic Substance Control Act (15 USCS 2601) to use a model organism to test the effects of a crop additive. Daphnids are typical model species used for aquatic toxicity studies (Jaafarzadeh et al., 2013). Daphnids are a vital part of the aquatic food chain as they are primary consumers (Lovern and Klaper, 2006); therefore, any disruption to their livelihood could have a dramatic effect on the ecosystem. Gibberellic acid has been tested by the US Environmental Protection Agency (EPA), but…
