Whiteflies ndi tizilombo tating'ono tofanana ndi njenjete, zochepa kwambiri (kukula kwake sizoposa 2 mm), zophimbidwa ndi mungu wofiira kapena wachikasu. Kwa nthawi yoyamba obereketsa mbewu anakumana ndi tizilombo toyambitsa matenda m'ma 80s a zaka za m'ma 1900 ndipo kuyambira apo sipanakhalepo wowonjezera wowonjezera wowonjezera kutentha kumene sikukanatha kuwona mliri uwu.
Whiteflies amawononga kwambiri zomera. Sikuti amadyetsa timadzi timeneti, komanso amadya kwambiri kuposa momwe amafunira kuti azipeza zofunika pamoyo wawo, ndipo ndalamazo zimaperekedwa pamwamba pa masamba. Mu bowa wambiri wamchere amachulukitsa, zomwe zimapangitsa kuphwanya kupuma kwabwino ndi photosynthesis. Kuphatikiza apo, whiteflies ndi odwala matenda osiyanasiyana omwe amavulaza zomera.
Pafupifupi aliyense amene amamera masamba kapena maluwa, posakhalitsa amakumana ndi vuto la momwe angawononge whitefly mu wowonjezera kutentha. Sikophweka kuchita izi, ndipo kupambana kwa njira zowatetezera zomera kumbali ya tizilomboti kumadalira zinthu zambiri, makamaka, pakufala kwa matenda.
Mosakayika, kupewa ndi njira yoyamba komanso yofunika kwambiri yomwe ingayambitsire ndi kuyambitsa vuto lolimbana ndi whitefly mu wowonjezera kutentha. Njira zothandizira ndi izi:
- Kawirikawiri whitefly imabweretsedwa ku wowonjezera kutentha kuchokera kunja komwe mutabzala. Choncho, mosamala mwatsatanetsatane zomwe zinapangidwa kuti zikhale ndi matenda - kukhalapo kwa mazira pa underside wa masamba.
- Misampha yovuta. Ndi ntchito yoteteza, matepi wamba kuti agwire ntchentche zodziwika bwino, koma mukhoza kugula mwapadera kuti muzilimbana ndi mbalame zowonongeka.
Koma ngati whitefly itapezeka kale mu wowonjezera kutentha pa tomato, udzu winawake wambiri, hibiscus ndi zina zotero, uyenera kutenga njira zothana nazo, kuti muteteze zomera.
Whitefly mu wowonjezera kutentha: njira zovuta
1. Kodi kuchotsa whitefly kuchokera ku wowonjezera kutentha ndi njira yotani? Njirayi ndi yoyenera kuti dera lomwe likukhudzidwa ndi tizilombo si lalikulu kwambiri. Choncho, masamba a chomera chilichonse, otetezedwa ndi tizilombo ta parasitic, ayenera kutsukidwa ndi sopo yankho, kutsuka mazira kuchokera kwa iwo.
Komanso pofuna kupewa, kuchotsa whitefly mu wowonjezera kutentha, mungagwiritse ntchito misampha ya glue - yogula kapena yopanga. Kuzipanga izo ndi zophweka: makatoni amadulidwa ndi magalasi 8 pa 8 sm ndipo amaikidwa ndi rosin, honey, Vaselinum. Kawirikawiri njira yamagetsi siilikwanira ndipo wina amayenera kuchita zina zowonjezera.
Njira zachilengedwe - zimagwiranso ntchito pachigawo choyamba cha matenda, pamene chiwerengero cha zomera zogwira ntchito akadakali kakang'ono. Monga njira zachilengedwe zolimbana zimagwiritsidwa ntchito:
- kulowetsedwa kwa dandelion - 40 g masamba ndi 30 g ya rhizomes ayenera kudzazidwa ndi lita imodzi ya madzi ndikuumiriza maola 3, ndiye pitirizani kupopera mbewu mankhwalawa. Ndondomeko iyenera kuchitika milungu iwiri iliyonse mpaka vuto lisathe;
- Mthunzi wa nkhuni - umafalitsa mofanana pamwamba pa nthaka;
- adyo kulowetsedwa - 100 g adyo denticles kutsanulira 500 ml ya madzi ndikuumirira masiku 4-5. Kupopera mbewu mankhwalawa, 5 g wa kulowetsedwa amadzipiritsika pa lita imodzi ya madzi.
3. Njira zamagetsi. Ngati zitsanzozi sizinathandize kuthana ndi whitefly mu wowonjezera kutentha, muyenera kulingalira za momwe mungagwirire ndi tizilombo mothandizidwa ndi tizilombo toyambitsa matenda. Mwachitsanzo, alimi odziwa bwino amalangiza mankhwala acta, omwe amasonyeza bwino kwambiri polimbana ndi tizilombo toyamwa. Ndibwino kuti muzigwirizanitsa ndi chida china - chigamba pazochitikazo pamene pakufunika kuchotsa whitefly mwamsanga.
