Ingano nigihingwa cyingenzi cyibiribwa kwisi, kandi abarenga 40% byabatuye isi barya ingano nkibiryo byingenzi.Umwanditsi aherutse gushishikazwa n’imiti yica imirima y ingano, kandi yagiye ashyira ahagaragara abasezerewe mu mirima itandukanye y’ibyatsi.Nubwo ibintu bishya nka pinoxaden bihora bisohoka, urebye ko kugenzura ibyatsi bimwe bidasanzwe mumirima yingano hamwe nintego imwe yibikorwa bishya bisaba ibicuruzwa bifite uburyo bwihariye bwibikorwa & ntibyoroshye kubyara imbaraga zo kuvangwa kugirango bigerweho ingaruka za kurandura kabiri, kugabanya ikiguzi cyo gukoresha umurima, nibindi, amasura amwe aracyari imbaraga nyamukuru yo guca nyakatsi mumirima yingano, kandi akomeza kugira uruhare rudasimburwa.Igicuruzwa cyasobanuwe hano hasi ni umwanzi wibyatsi bigari mumirima yingano, ikoreshwa cyane, irwanya ubushyuhe buke cyane, irinda cyane ingano, nubukungu.Iyi miti yica ibyatsi ni Florasulam.

Florasulam ni pirimidine ya gatanu ya triazole yakozwe neza na Dow AgroSciences hagati ya za 90 nyuma ya sulfentrazone, sulfentrazone, dicoxsulam na sulfentrazone.Sulfonamide ibyatsi.Byatangajwe mu 1998-1999, ahanini bikoreshwa mu kurwanya nyakatsi nini y’amababi mu murima w ingano.Ingaruka zo gukumira.Kuva yashyizwe ku isoko mu 2000, yabaye imwe mu ntera yo kugurisha kwa Dow AgroSciences, kandi umuvuduko w’ubwiyongere wabaye mwiza mu myaka yashize.

Uburyo bwibikorwa

Florasulam ni iyitwa triazolopyrimidine sulfonamide yo mu bwoko bwa herbiside kandi ni synthase ya acetolactate (ALS).Muguhagarika synthase ya acetolactate mubihingwa, ibuza biosynthesis ya aside amine acide kuruhande nka valine, leucine na isoleucine, kugirango igabana rya selile ridahagarikwa, imikurire isanzwe yibyatsi irarimbuka, kandi urumamfu rurapfa.

Florasulam ifite uburyo bwiza bwo kwifata, bushobora kwinjizwa namababi y’ibiti n’imizi, bikanduzwa mu bimera byose, kandi bikarundanyirizwa muri meristem kugira ngo bitere urupfu rw’ibimera.Kubwibyo, urumamfu rwariciwe rwose kandi ntihazongera kubaho ukundi.

Gusaba

Florasulam ikoreshwa cyane cyane mugihe cyo kuvuka no kuvura amababi mumirima yingano kugirango irinde ibyatsi bibabi byamababi, harimo Artemisia somnifera, isakoshi yumwungeri, gufata kungufu ishyamba, ibyago byingurube, inkoko, inkoko zinka, icyari kinini, umuceri chakra, Inkware yumuhondo, Maijiagong hamwe nibindi bigoye-kurwanya-nyakatsi, kandi bifite ingaruka nziza cyane zo kubuza Ze Lacquer (Euphorbiaceae) mu murima wingano.Irashobora kandi gukoreshwa kuri sayiri, ibigori, soya, ipamba, urumuri rwizuba, ibirayi, imbuto za pome, igitunguru nicyatsi, urwuri, nibindi. Igihe cyo kubisaba ni kinini, kandi gishobora gukoreshwa mbere yimbeho kugeza mu mpeshyi.

Outlook

Florasulam ifite ibyiza byo gukoresha kandi ni ibyatsi bidashobora guhingwa kumirima yingano.Nyamara, ibibi bya Florasulam nuko umuvuduko wibyatsi byapfuye bitinda kandi aho ibikorwa byakorewe ni umwe.Kubwibyo, birakenewe gukoresha byuzuye birebire kandi ukirinda bigufi kugirango ubuzima bwisoko bwiyongere.
