Mealybug ndi amodzi mwa majeremusi owopsa kwambiri pamaluwa apanyumba, omwe amatsogolera kuwonongeka kwawo kwathunthu. Za momwe mungathanirane ndi majeremusi pazomera zamkati, zomwe mitundu ndiyofala kwambiri kuposa yomwe imatha kuwerengedwera.
Mealybug - momwe angamenyere nkhondo zamkati
Khola lotchedwa mealybug, kapena kuti loury, ndiloyamwa ndipo silingayang'anitsidwe zomera. Ichi ndi tizilomboti tating'onoting'ono tokhala ngati maimilimita 4 mpaka 6, kutengera mitundu. Chimawoneka ngati mphero yokhala ndi tinyanga yayitali. Ali ndi thupi loyera la shaggy lomwe limakhala ndi mabatani kumbali.
Pali mitundu itatu:
- nyanja yamchere;
- mwachidule;
- mphesa.
Mealybug
Mtengowo umavulazidwa ndi mphutsi za mealybug, zofanana ndi nkhupakupa. Amafika pamlingo woyambira 3 mm ndipo amasonkhanitsidwa m'magulu. Ali ndi miyendo yolimba, amatha kuyenda kuchoka pachomera kupita ku china. Amawonongera mbewu pomera mphukira, kutola makungwa kapena mababu. Zotsatira zake, maluwa amasiya kukula ndipo pang'onopang'ono amafa.
Zofunika! Ndikofunikira kuthana ndi majeremusi pochita mankhwalawa mwezi uliwonse a mbewu zomwe zili pachiwopsezo ndi sopo kapena mankhwala apadera.
Zimayambitsa tizilombo pazomera
Palibe yankho lenileni la funsoli, malinga ndi mikhalidwe iti, chifukwa chiyani ndipo majeremusi amawonekera. Komabe, nthawi zambiri zimawonekera mu zotsatirazi:
- kuthilira kwamadzi kapena kufota kwa dothi la chomera;
- kutentha kosankhidwa bwino, chinyezi ndi kuyatsa;
- kusoweka kwa miphika, kuchotsedwa kwadzidzidzi kwa ziwalo zouma komanso kusowa kwa njira zamadzi;
- kunyalanyaza kukhala payekha mutagula mbewu zatsopano.
Yang'anani! Kuphatikiza apo, mealybug imawoneka chifukwa cha kufalikira kwakukulu ndi fumbi m'malo okhala mbewu. Chifukwa chake, amafunikira chithandizo chokwanira.
Zizindikiro za matenda
Zizindikiro kuti chikhalidwechi chatenga matenda ndipo muyenera kuyambiranso majeremusi, nthawi zambiri chimawoneka motere:
- Masamba amawoneka ofunda kapena mtundu wa ubweya wa thonje. Pali mazira a tizilombo, pomwe mphutsi zimaswa, zomwe zimakwawa m'maluwa ndikuyambira ndikuziwononga.
- Chikhalidwe chimayamba kutsalira pakukula, kuuma mwachangu ndi kufa.
- Masamba ndi masamba amagwa, maluwa amayima, masamba amakhala povutirapo ndi wachikasu.
- Mphukira ndi zopindika, matumpso oyera otumphukira amawoneka, omwe kenako amasintha.
Kuphatikiza apo, kuchuluka kwa madontho oyera kumatha kuwonekera padziko lapansi la mbewu. Ichi chizikhala poyambira kuti zichotse tizilombo ku maluwa azamba.
Zizindikiro
Zizindikiro za chomera chowonongeka
Mbewu ikakhudzidwa ndi nsabwe za shaggy, imaleka kukula ndikuwonetsa maluwa. Komanso, ikauma, masamba amagwa. Chizindikiro chofunikira kwambiri ndikuwonongeka ndikuwoneka kwovala koyera paz masamba, ndikufanana ndi ufa ndi tizilombo tambiri tambiri tomwe timatha kuchotsedwa ndikuphwanyidwa ndi zala zanu.
Yang'anani! Nthawi zina, chizindikiro cha matenda chimasinthidwa masamba.

Mitundu yazomera
Koyambira nkhondo yolimbana ndi mealybug
Poyang'ana koyamba, nkovuta kudziwa kuti chitsamba chidwala kachilombo, chifukwa chikhalidwecho chimaphimbidwa ndi utoto woyera, wofanana ndi bowa kapena nkhungu. Chifukwa chake, poyambira gawo, ndikofunikira kusankha zomwe mukumenyanabe. Pambuyo pake, muyenera kugwiritsa ntchito njira imodzi yotchuka yothanirana ndi tizilombo. Izi zitha kuchitika pogwiritsa ntchito mankhwala otsimikiziridwa kapena kugwiritsa ntchito njira zamwambo. Ndikofunika kumaliza ntchito ndikuchotsa tizilombo tambiri. Monga lamulo, kuti mugonjetse tizilombo tambiri, zimatenga masiku 10-12.
Yang'anani! Zomera zapafupi ziyenera kuthandizidwa kuti zisamathenso.
Kodi ndingapewe bwanji mealybug pazomera zamkati
Anthu ambiri amagwiritsa ntchito kukonzekera kwa mankhwala azitsamba ndi wowerengeka monga njira zotchuka kwambiri zogwirira ntchito. Mwa omaliza, nthawi zambiri amatembenukira ku sopo yothetsera sopo, kaphatikizidwe kamankhwala azitsamba (mwachitsanzo, calendula kapena mahatchi), mafuta a azitona ndi madzi, yankho lamadzi a adyo, tincture wa lalanje ndi mandimu.
Njira ina yothandiza kwambiri pochiza mizu ya chomera ndi madzi otentha ndikuwuthira mu mphika watsopano wokhala ndi dothi lamiyala yatsopano. Zimathandizanso kutsuka chomera pansi pamadzi ofunda, ndikumasunthira kumalo atsopano ndi gawo lapansi ndikutchinjiriza nthawi ndi yankho la mandimu.
Yankho la sopo
Zithandizo za anthu amchikhalidwe: Njira yothira sopo
Njira yothetsera sokosi ndi mowa ndi imodzi mwazida zabwino kwambiri zothetsera vuto mwachangu ngati mealybug. Zomwe zimafunika ndikutenga sopo wina aliyense ndikuusunthira m'madzi ofunda mpaka atasungunuka kwathunthu. Ndipo onjezerani supuni 1 ya mowa wamphamvu kapena mowa wosamwa. Pogwiritsa ntchito kukonzekera, phulirani mankhaka katatu ndi masiku 7.
Yang'anani! Akatswiri a anthu amatsimikizira kuti sipadzakhala chilichonse chokhala ndi majeremusi, ndikuti mbewu yomwe yakhudzidwa itha kutulutsa maluwa okongola ndikukula.
