Momwe mungachotsere psyllids (psyllids)

Pali mitundu yopitilira 100 ya timapepala yomwe imapezeka ku North America konse. Umu ndi momwe mungawazindikire ndikuchotsa pogwiritsa ntchito mankhwala otsimikiziridwa, achilengedwe komanso achilengedwe.

Nsabwe zamasamba, zomwe nthaŵi zina zimatchedwa kudumpha zomera, zimadya zomera zosiyanasiyana, kuphatikizapo mitengo yambiri ya zipatso ndi zipatso zing’onozing’ono, komanso tomato ndi mbatata. Akuluakulu ndi anapiye amadya poboola pamwamba pa tsamba ndi kutulutsa madzi a m'maselo. Izi zimapangitsa masamba (makamaka masamba akumtunda) kukhala achikasu, kupindika, kenako kufa. Uchi wotulutsidwa kuchokera kumasamba umalimbikitsa kukula kwa nkhungu zakuda, za sooty. Mitundu yambiri imakhala ndi ma virus omwe amafalitsa matenda.

Chizindikiritso

Akuluakulu (1/10 inchi utali) ndi ofiira-bulauni mu mtundu, ndi mapiko oonekera ndi amphamvu kudumpha miyendo. Zimakhala zokangalika ndipo zimalumpha kapena kuwulukira ngati zasokonezedwa. Mbalamezi ndi zathyathyathya komanso zowoneka ngati elliptical, pafupifupi mamba. Sagwira ntchito kwambiri kuposa akuluakulu ndipo ndi ochuluka kwambiri pamunsi mwa masamba. Nymphs zomwe zangotuluka kumene zimakhala zachikasu, koma zimasanduka zobiriwira zikamakula.

Taonani: Masamba amakhala amodzi, kutanthauza kuti amakhala enieni (mtundu uliwonse umadya mtundu umodzi wokha wa mbewu).

Mayendedwe amoyo

Akuluakulu overwinter m'ming'alu ya mitengo ikuluikulu. Kumayambiriro kwa kasupe, zimaberekana ndipo zazikazi zimayamba kuikira mazira achikasu-lalanje m'ming'alu yozungulira masamba ndi masamba pamene masamba atseguka. Kutulutsa kumachitika pambuyo pa masiku 4-15. Mbalame zobiriwira zachikasu zimadutsa m'miyendo isanu mkati mwa masabata 2-3 asanafike msinkhu. Malingana ndi mitundu, pali mibadwo imodzi mpaka isanu pachaka.

Momwe mungadzilamulire

1. Utsi horticultural mafuta kumayambiriro kasupe kupha overwintering akuluakulu ndi mazira.
2. Tizilombo zopindulitsa monga ladybugs ndi lacewings ndizofunikira kwambiri zodya tizilombo toyambitsa matenda. Kuti mupeze zotsatira zabwino, masulani pamene milingo ya tizirombo tatsika kwambiri.
3. Ngati anthu ali ochuluka, gwiritsani ntchito mankhwala ophera tizilombo osakhalitsa komanso osakhalitsa kuti muwalamulire, kenako mutulutseni tizilombo tolusa kuti tipewe kuwononga.
4. Dziko la Diatomaceous liribe ziphe zapoizoni ndipo limagwira ntchito mwachangu mukakumana. Kuwaza mbewu zamasamba mopepuka komanso molingana kulikonse komwe kuli akuluakulu.
5. Sopo ya Safer® insecticidal imagwira ntchito mwachangu ku matenda oopsa. Mankhwala achilengedwe okhala ndi nthawi yayitali yochitapo kanthu, amagwira ntchito powononga gawo lakunja la tizilombo tofewa, zomwe zimayambitsa kutaya madzi m'thupi ndi kufa mkati mwa maola angapo. Ngati kuli tizilombo, ikani madzi okwanira 2.5 oz/gallon, bwerezani masiku 7-10 aliwonse ngati pakufunika.
6. Zozungulira WP (dongo la kaolin) limapanga filimu yotchinga yotchinga yomwe imakhala ngati chitetezo choteteza mbewu kuti zisawonongeke ku tizirombo.
7. BotaniGard ES ndi mankhwala othandiza kwambiri ophera tizilombo Boveria Basiana, bowa wa entomopathogenic womwe umakhudza mndandanda wautali wa tizirombo, ngakhale mitundu yosamva! Kugwiritsa ntchito mlungu uliwonse kumatha kuletsa kuphulika kwa tizilombo komanso kupereka chitetezo chofanana kapena chabwinoko kuposa mankhwala ophera tizilombo.
8. Mafuta a neem 70% amavomerezedwa kuti agwiritsidwe ntchito ndi organic ndipo amatha kupopera masamba, mitengo yazipatso ndi maluwa kuti aphe mazira, mphutsi ndi tizilombo tating'onoting'ono. Sakanizani 1 oz/gallon yamadzi ndikupopera masamba onse (kuphatikiza pansi pa masamba) mpaka anyowe.
9. Ngati tizilombo tating'onoting'ono sitingathe kupirira, samalirani madera masiku 5 mpaka 7 aliwonse ndi mankhwala ovomerezeka kuti agwiritse ntchito organic. Kuwongolera moyenera kumafuna kuphimba bwino pamwamba ndi pansi pa masamba omwe ali ndi matenda.

Langizo: Osachulukitsa feteleza - kuyamwa tizilombo monga mbewu zokhala ndi nayitrogeni wambiri komanso zofewa zatsopano.
