4-Chlorophenoxyacetic acid imatha kulimbikitsa kusintha kwa biosynthesis ndikusintha kwachilengedwe kwa zomera. Sizingateteze kugwa kwamaluwa ndi zipatso, kuwonjezera kuchuluka kwa zipatso, kuonjezera kukula kwa zipatso, kulimbikitsa kukhwima koyambirira, komanso kukwaniritsa cholinga chokhazikitsa mtundu wazomera, komanso uli ndi ntchito ya herbicide. Amagwiritsidwa ntchito makamaka mu tomato, mphesa, ndiwo zamasamba, kukonza zokolola komanso mtundu wa mbewu, ndipo imakhala yothandiza kwambiri.

4-Chlorophenoxyacetic acid ndi phenoxy chomera chokula chowongolera chomwe chimakhala ndi zochitika za auxin. Imadzala ndi mizu, zimayambira, masamba, maluwa ndi zipatso, zomwe zimakhalako kwanthawi yayitali. Mphamvu yake yakuthupi ndiyofanana ndi ya aminoxin yamkati. Zimathandizira magawano am'maselo ndi kusiyanitsa minofu, zimathandizira kukulitsa kwa ovary, kuyambitsa chipatso chimodzi, kupanga zipatso zopanda mbewu, kulimbikitsa kolowera zipatso ndi kukulitsa zipatso, kupatsa zipatso zopanda mbewu, kupewa maluwa ndi kutsika kwa zipatso, kulimbikitsa kukula kwa zipatso, kukhwima kale, kuwonjezera zokolola, kusintha mtundu, etc.

Amagwiritsidwa ntchito makamaka ku tomato pofuna kupewa maluwa ndi zipatso kuti zisagwe. Itha kugwiritsidwanso ntchito kukulitsa kupanga ndi kupeza mbewu zosiyanasiyana monga biringanya, tsabola, mphesa, zipatso, mpunga, tirigu ndi zina zotero.

Itha kupitsitsanso kukhazikika ndikuchepetsa kuchepa kwamasamba posungira
