Bitandukanye nuburyo bwinshi bwo guhitamo imiti igabanya ubukana mu bice byumuceri, buriwese ufite ibyiza n'ibibi, kuri ubu pymetrozine nibicuruzwa byayo bivanze biracyafite umwanya munini ku isoko mubashinzwe kugenzura ibihingwa byumuceri, nibindi bicuruzwa ntibizashobora kunyeganyeza nimero ya mbere yo gukoresha umwanya mugihe gito. imiterere.

Dilemma ya Pymetrozine

Mugihe ubushobozi bwibikorwa byamasosiyete atandukanye yibiyobyabwenge byasohotse buhoro buhoro, irushanwa ryimiti yo mumirima riragenda rikomera. Pymetrozine ikoreshwa cyane mugucunga aphide ahantu h'umuceri no mubice bimwe byimbuto byimbuto. Kugeza ubu, nta cyerekezo kigaragara aho dosiye ishobora kwiyongera, bigatuma iki gicuruzwa gihinduka uruganda rukora ibiyobyabwenge. , abategura imyiteguro, ndetse nababigurisha nabacuruzi bose baragabanutse mugihe inyungu zoroheje zahindutse ibicuruzwa.

Ibura ry'itangwa mu nganda zikenewe byanze bikunze bizatuma habaho kwaguka ku buryo budasubirwaho ubushobozi bwo gutanga umusaruro. Ababikora benshi bazinjira mumasoko ashyushye kugirango bahatane, bivamo inyungu ntoya kandi ntoya. Kubera iyo mpamvu, pymetrozine imwe rukumbi yatangiye guhatanira ibiciro, buhoro buhoro ihinduka ibicuruzwa bivangavanze, nabyo byatangiye guhatanira ibiciro. Bitewe nimpamvu nyinshi nko guhererekanya ubushobozi bwumusaruro, ubugenzuzi bukomeye bwo kurengera ibidukikije, no kudahuza itangwa nigihe cyagenwe, igiciro cyibiyobyabwenge cyambere cyahindutse kirenze uko byari byitezwe na buri ruganda, bigatuma abakora ibicuruzwa byo hasi bakora pymetrozine bagwa mubibazo, cyane cyane abakora formulaire badashyigikiwe nibiyobyabwenge byumwimerere.

Isoko ryumuceri ni ikibuga cyuruganda rukora inganda nyinshi, ariko usibye triflufenac, yamenyekanye cyane mumyaka yashize, kubakora inganda nyinshi, ntabicuruzwa byinshi byiza usibye pymetrozine yo gukumira no kugenzura ibihingwa byumuceri. Guteza imbere. Imikorere yisoko ya dinotefuran nibyiza, ariko ugereranije na pymetrozine, dinotefuran irasa nkumunywanyi mwiza mubijyanye no kuzamurwa kwukuri, kubishyira mubikorwa no gukora neza, ntabwo ari umusimbura utandukanye, kandi bizashira vuba. Yakurikiranye inzira ishaje yo guhatanira igiciro hamwe na pymetrozine, ntabwo rero yari ifite imikorere ishimishije cyane.

Icyerekezo cy'isoko

Ibicuruzwa bihendutse nibiciro byumusaruro nibintu bibiri byibanda kubakora muri rusange. Ugereranije n’umusaruro rusange w’umusaruro w’ubuhinzi, ikiguzi cy’imiti yica udukoko ntikigizwe n’igice kinini, ariko ubu abahinzi barangiza barita cyane ku bicuruzwa bishobora kuzigama igihe n’ibiciro by’umurimo.

Kugena igiciro cyo kugura ibikoresho fatizo nigikorwa cyingenzi kubakora ibicuruzwa byo hasi mugucunga ibiciro byumusaruro. Isoko ryibiyobyabwenge byumwimerere birasa neza, ariko bigenda bihindagurika rimwe na rimwe. Niba abakora imyiteguro bakorana cyane nabatanga ibicuruzwa bishobora gutanga amasoko meza nindirimbo, bivuze ko bashobora kuzigama neza ibiciro byamasoko kandi bagashyira imbaraga zabo hamwe nubutunzi bwabo mukwitabira amarushanwa kuruhande rwitegura. Muri iri soko ryisi yose, Kugirango ushimangire umwanya waryo mwisoko "ryiyongera".
Tuzategereza turebe uzavamo iyi mirwano kandi azakurikiraho gukurikira kurwanya udukoko twumuceri.
