“…Terpenoids present in cotton plants are known to deter feeding by leaf‐chewing insects as well as to reduce the growth rate of several species of pests . Gossypol is the best studied cotton terpenoid and it is present in different parts of the plant such as seeds, roots and leaves . Other toxic terpenoids such as hemigossypol and desoxy‐hemigossypol are present in the roots and the so‐called gossypol‐like terpenoids such as hemigossypolone, heliocide H1, heliocide H2, heliocide H3 and heliocide H4 are present in seeds, flowers, buds and leaves .…”

“…Cotton plants produce a range of non-volatile terpenoids, such as gossypol and a variety of other gossypol-like terpenoids, that are toxic for a wide range of herbivores and pathogens. 50,51 Terpenoids present in cotton plants are known to deter feeding by leaf-chewing insects as well as to reduce the growth rate of several species of pests. [51][52][53][54] Gossypol is the best studied cotton terpenoid and it is present in different parts of the plant such as seeds, roots and leaves.…”

Enhancing cotton pest management using plant natural defenses has been described as a promising way to improve the management of crop pests. We here reviewed various studies on cotton growing systems to illustrate how an ancient technique called plant training, which includes plant topping and pruning, may contribute to this goal. Using examples from cotton crops, we show how trained plants can be brought to a state of enhanced defense that causes faster and more robust activation of their defense responses. We revisit the agricultural benefits associated with this technique in cotton crops, with a focus on its potential as a supplementary tool for integrated pest management (IPM). In particular, we examine its role in mediating plant interactions with conspecific neighboring plants, pests and associated natural enemies. We propose a new IPM tool, plant training for induced defense, which involves inducing plant defense through artificial injury. Experimental evidence from various studies shows that cotton training is a promising technique, particularly for smallholders, which can be used as part of an IPM program to significantly reduce insecticide use and to improve productivity in cotton farming. © 2018 Society of Chemical Industry.

“…Classically, analysis of cottonseed or other material for gossypol has been carried out using colorimetric methods, usually based on the formation of colored condensation products with aromatic amines (Nazarova et al 1981). More recently, these methods have been entirely replaced by HPLC methods.…”
