Plant growth regulators products

The ideal plant growth regulator should leave no harmful persistent residue in a finished product or crop and the paradigm compounds are ones that have high specific activity, are target specific, and are environmentally biodegradable.

Ultraviolet irradiation of the fungicide and plant growth regulator 69 in solution yields four products, with overall conversion of 37% in 3 days. The photodimer 70, which is the product obtained in lowest yield in solution, is obtained as the sole product (quantitative yield) after only 5 hrs of irradiation of the solid (149). 

Other products represent only a small share of the crop protection market with plant growth regulators being the largest of this sector and other product types including rodenticides, molluscicides, avicides and nematicides. 

The notion of using exogenous chemicals to control plant growth, and hence productivity, is not new. Many of the first commercial herbicides (auxin herbicides) were developed as a direct consequence of plant growth regulator research (see Chapter 1, Section 3.3).
