Phatikizani Kukonzekera

Bicyclopyrone ikhoza kuphatikizidwa ndi mankhwala ophera udzu osiyanasiyana monga Mesotrione, Isoxaflutole, Topramezone, ndi Tembotrione.Posakanikirana ndi zoteteza benoxacor kapena cloquintocet, Bicyclopyrone imatha kupititsa patsogolo chitetezo ku mbewu.Mitundu yosankha ya herbicide imakhala ndi ntchito yabwino yolimbana ndi udzu wambiri komanso udzu wosatha komanso wapachaka, ndipo itha kugwiritsidwa ntchito m'minda ya chimanga, tirigu, balere, nzimbe ndi mbewu zina.

Ngakhale kuti Bicyclopyrone yakhala pamsika posachedwa, ntchito yake ya patent inalipo kale, ndipo patent yake yapawiri ku China (CN1231476C) yatha pa June 6, 2021. Kuyambira pano, Shandong Weifang Runfeng Chemical Co., Ltd. 96% ya mankhwala oyambirira a Bicyclopyrone.Ku China, kulembetsa kwa zokonzekera zake sikunali kanthu.Opanga osowa amatha kuyesa mankhwala ake apawiri ndi Mesotrione, Isoxaflutole, Topramezone, ndi Tembotrione.

Chiyembekezo cha Msika

Chimanga ndiye mbewu yofunika kwambiri yogwiritsira ntchito Bicyclopyrone, yomwe imawerengera pafupifupi 60% ya msika wake wapadziko lonse lapansi;Bicyclopyrone ndi yomwe imagwiritsidwa ntchito kwambiri ku United States ndi Argentina, yomwe imawerengera pafupifupi 35% ndi 25% ya msika wapadziko lonse lapansi, motsatana.

Bicyclopyrone imakhala ndi mphamvu zambiri, kawopsedwe kakang'ono, chitetezo chambiri cha mbewu, sichosavuta kupanga kukana mankhwala, ndipo ndi otetezeka komanso ochezeka ku chilengedwe.Zikuyembekezeka kuti malondawo adzakhala ndi chiyembekezo chabwino pamsika m'minda ya chimanga m'tsogolomu.
