The Allium Leaf Miner inowanikwa kuEurope, asi yakawanikwa kuPennsylvania muna 2015. Inhunzi ine makonye anodya zvirimwa zverudzi rweAllium, kusanganisira hanyanisi, gariki, nerikisi.
Kubva payakasvika kuUnited States, yakapararira kuNew York, Connecticut, Massachusetts, Maryland, uye New Jersey uye inoonekwa senjodzi huru yekurima.Chikwata chevaongorori chinotungamirwa naCornell chakaita bvunzo dzemumunda pane gumi nemana zvinoshandiswa mumishonga yezvipembenene uye vakazvishandisa nenzira dzakasiyana siyana kuti vanzwisise nzira dzekurapa dzakanakisa.
Zvakawanikwa nevaongorori zvakatsanangurwa muongororo yakabudiswa muna Chikumi 13 mu “Journal of Economic Entomology” yakanzi “The Digger for Management of Alliums: Emerging Diseases and Pests of Allium Crops in North America.”
Boka rekutsvagisa rinotungamirwa nemunyori mukuru Brian Nault, purofesa wezvezvipembenene paCornell Agricultural Technology, uye mumwe weanotungamira Allium mashizha ekuchengetedza zvipembenene muUnited States, akawana akawanda echinyakare mishonga yekuuraya zvipembenene yemakemikari Iyo ine simba rakanakisa pazvipembenene zvinopinda.
Nault akati: “Kumapurazi asingashandisi maturusi ekushandisa zvakanaka-anogadzira mishonga yezvipembenene-dambudziko reallium foliaricides rinowanzonyanya kukura.
Phytomyza Gymnostoma (Phytomyza Gymnostoma) ine zvizvarwa zviviri pagore, uye vanhu vakuru vanoonekwa munaEpril uye pakati paSeptember.Muchirimo, hanyanisi zhinji dzinokura, uye panombomira pakati pezviviri izvi, izvo zvinoita kuti goho ripukunyuke tumbuyu.Saizvozvowo, magirobhu ehanyanisi anokura nekukurumidza, izvo zvinoita kuti nguva yeshizha itadze kunyatsotsvaga chikafu.
Pakati pevakuru vemigodhi, zvirimwa zvine mashizha akasvibira zvinonyanya kutyisidzirwa.Kuchamhembe kwakadziva kumabvazuva kweUnited States, chirimo chinosanganisira mariki, mascallions negariki, uye matsutso anosanganisira mascallions nerikisi.Mhuka dzemusango dzinotora zvizvarwa zviviri dzinogona kuva dura rekukura kwezvipembenene.
Makonye anotanga kufura pamusoro pechirimwa achienda kuzasi kuti akwire.Makonye anogona kuparadza tsinga dzeropa, zvichikonzera hutachiona hwehutachiona kana fungal uye kukonzera kuora.
Chikwata chekutsvagisa chakaedza nzira dzakasiyana dzekutarisira nehanyanisi, leeks uye girini hanyanisi muPennsylvania neNew York muna 2018 uye 2019. Kumwaya mishonga inouraya zvipembenene (dimethylfuran, cyanocyanoacrylonitrile uye spinosyn) ndiyo nzira inowirirana uye inoshanda, inoderedza kukuvadzwa kusvika ku89% uye kupedza zvipembenene kusvika pa95%.Dichlorofuran uye cyanocyanoacrylonitrile inoshandiswa nedhip irrigation haishande.
Mimwe mishonga yezvipembenene (abamectin, paracetamol, cypromazine, imidacloprid, lambda cyhalothrin, methomyl uye spinosyn) yakaderedzawo kuwanda kweallium foliaricides.Spinosyn inoshandiswa kumidzi isina midzi kana mapulagi ekushandiswa kwechirimwa, kuderedza kukuvadzwa kwezvipembenene mushure mekusimwa ne90%.
Kunyange zvazvo vanochera onion veallium vasati vava dambudziko rehanyanisi kusvika pari zvino, vatsvakurudzi nevarimi vanonetsekana kuti vanogona kuzonetsa kana vakakwanisa kudhonza uye vakatamira kumadokero (kunova ndiko kurimwa kwehanyanisi).Nat akati: "Iri ragara riri dambudziko rakakura kuindasitiri yehanyanisi yekuAmerica."
