Nzira yekubvisa sei psyllids (psyllids)

Kune anopfuura zana marudzi emapepa anowanikwa muNorth America yese. Heano maitiro ekuvaziva uye kuvabvisa uchishandisa zvakaratidzwa, zvechisikigo uye organic marapirwo.

Inda dzemashizha, dzimwe nguva dzinonzi jumping plant lice, dzinodya zvirimwa zvakasiyana-siyana, kusanganisira miti yemichero yakawanda nemichero miduku, pamwe chete nemadomasi nembatatisi. Vese vakuru nenyuchi vanodya nekuboora pamusoro peshizha uye kubvisa muto wesero. Izvi zvinoita kuti mashizha (kunyanya mashizha ekumusoro) ave yero, kupeta, uye pakupedzisira kufa. Huchi hunoburitswa kubva mumashizha hunokurudzira kukura kwerima, sooty molds. Mhando dzakawanda dzinotakura mavhairasi anoparadzira zvirwere.

Chiratidzo

Vakuru (1/10 inch kureba) vane ruvara rutsvuku-ruvara, vane mapapiro akajeka uye makumbo akasimba ekusvetuka-svetuka. Dzinoshingaira uye dzinosvetuka kana kubhururuka dzichienda kana dzakanganiswa. Mhungu dzakati sandarara uye dzakaita elliptical muchimiro, dzinenge dzine makwapa. Ivo havanyanyi kushanda kupfuura vanhu vakuru uye vanonyanya kuwanda pasi pemashizha. Mhungu dzichangochochonywa dzine ruvara rweyero, asi dzinoita girinhi padzinokura.

Cherechedza: Leaflids ndeye monophagous, zvichireva kuti inogara chaiyo (rudzi rwega rwega runodya pamhando imwe chete yemiti).

Kutenderera kwehupenyu

Vakuru overwinter mumikaha yehunde dzemiti. Mukutanga kwechirimo dzinosangana uye hadzi dzinotanga kukandira mazai eorenji-yero mumikaha yakatenderedza mabuds uye pamashizha kana mashizha angovhurwa. Kuchechenya kunoitika mushure memazuva 4-15. Yellow-green nymphs inoenda nepakati shanu mukati memavhiki maviri-2 isati yasvika padanho revakuru. Zvichienderana nerudzi, kune chizvarwa chimwe kusvika kushanu pagore.

Kudzora sei

1. Pfaya horticultural mafuta mukutanga kwechirimo kuuraya overwintering vakuru nemazai.
2. Zvipembenene zvinobatsira zvakadai sema ladybugs uye lacewings zvakakosha zvisikwa zvinodya chipembenene ichi. Kuti uwane mibairo yakanaka, regedza kana huwandu hwezvipembenene hwadzikira kusvika pakati nepakati.
3. Kana vanhu vawanda, shandisa mushonga unouraya zvipembenene ushoma uye unogara kwenguva pfupi kuti ugadzirise, wobva wasunungura twupukanana kuti urambe uchitonga.
4. Diatomaceous pasi haina chepfu uye inoita nekukurumidza kana yasangana. Mwaya zvirimwa zvemuriwo zvinyoro uye zvakaenzanirana pose pane vanhu vakuru.
5. Safer® insecticidal sipo inoshanda nekukasira pakubata kwakasimba. Mushonga wezvipembenene wechisikigo une nguva pfupi yekuita, unoshanda nekukuvadza kunze kwechipembenene chezvipembenene zvakapfava, zvichikonzera kupera kwemvura uye kufa mukati memaawa mashoma. Kana zvipembenene zviripo, shandisa 2.5 oz/gallon yemvura, dzokorora mazuva ose 7-10 sezvinodiwa.
6. Yakapoteredza WP (kaolin clay) inoumba firimu rinodzivirira rinoshanda sechirimwa chakakura chinodzivirira kudzivirira kukuvadzwa kubva kune zvipembenene.
7. BotaniGard ES mushonga wezvipembenene unoshanda zvakanyanya une Boveria Basiana. Kushandiswa kwevhiki nevhiki kunogona kudzivirira kuputika kwezvipembenene uye kupa dziviriro yakaenzana kana nani pane yakajairwa mishonga yemishonga yemakemikari.
8. 70% yemafuta emu<em>neem anotenderwa kushandiswa ne<em>organic uye anogona kupfapfaidzwa pamuriwo, miti yemichero nemaruva kuuraya mazai, ma<em>larvae uye tupukanana twevakuru. Sanganisa 1 oz/gallon yemvura uye pfapfaidza mashizha ese (kusanganisira pasi pemashizha) kusvikira anyorova.
9. Kana huwandu hwezvipembenene husingatsungiririki, chengetedza nzvimbo mazuva mashanu kusvika manomwe ega ega nemushonga wezvipembenene unotenderwa kushandiswa kweorganic. Kudzora kunobudirira kunoda kufukidzwa kwakakwana kwezvose zviri pamusoro uye pasi pemashizha ane utachiona.

Zano: Usawedzere fetereza - kusveta zvipembenene zvakaita sezvirimwa zvine mwero wenitrogen wakakwira uye kukura kutsva kwakapfava.
