NAA and 2, 4-D are often employed for inducing flowering in litchi and pineapple. Application of auxins (e.g., IAA, IBA) and conjugate auxins {e.g., IBA-alanine) to unpollinated pistils make them develop into seedless fruits (or parthenocarps) which carry a better market price than the normal fruits having seeds. 2, 4-D and 2, 4, 5-T are used as weedicides (herbicides) which destroy broad leaved weeds in cereal crops and lawns. Dalapon (2, 2-dichloropropionic acid) kills grasses in broad leaved crops.
