Momwe Mungachotsere Whitefly mu Greenhouse: Njira 4 Zotsimikiziridwa

Momwe mungazindikire whitefly mu wowonjezera kutentha

Whitefly pamasamba.

Whitefly ndi cholengedwa chaching'ono kwambiri. M'litali, thupi lake limangofika 2 mm. Kunja, ntchentche yoyera ndi yofanana kwambiri ndi njenjete yaing'ono yokhala ndi mapiko oyera oyera.

Kuwonjezera pa kukula kwake kochepa, tizilombo toyambitsa matenda timakhala ndi moyo wobisika, choncho zimakhala zovuta kuzindikira kukhalapo kwawo. Onse mphutsi ndi akuluakulu amathera nthawi yawo yambiri pansi pa masamba a zomera za chakudya. Mutha kuzindikira kukhalapo kwa tizilombo tating'onoting'ono pazifukwa izi:

• masamba a zomera anayamba kuzimiririka, kutembenukira chikasu, kupindika kapena kuphimbidwa ndi mawanga achikasu;
• tchire lomwe lili ndi kachilomboka limayamba kuchedwa kukula;
• pamwamba pa masamba mbale anakhala zomata;
• chomeracho chikagwedezeka, timizere tating'ono toyera timayamba kuyendayenda mozungulira;
• Pansi pa masamba pali mamba ang'onoang'ono owoneka bwino - mphutsi za whitefly.

Kudziwana kwambiri ndi whitefly kungapitirire pa ulalo uno. 

Momwe mungachotsere whiteflies mu wowonjezera kutentha

Nkhondoyo iyenera kuyamba mwamsanga zizindikiro zoyamba kuonekera, popeza tizilombo timatha kuberekana modabwitsa.

M'miyezi 1-1,5, gulu lalikulu la tizilombo toononga zitha kuwoneka kuchokera ku kagulu kakang'ono, komwe kumakhala kovuta kwambiri kupirira.

Njira zamakina zothana ndi whitefly

Sungani mu greenhouses.

Ngati tizilombo mu wowonjezera kutentha anaonekera posachedwapa ndipo chiwerengero cha anthu ndi ochepa, ndiye makina njira angagwiritsidwe ntchito. Kuti muchite izi, ndikokwanira kuchiza mbewu zomwe zili ndi kachilomboka ndi yankho la sopo. Motero, mazira ndi mphutsi zoikidwa pa izo zidzawonongedwa.

Akuluakulu amatha kuwulukira ku zomera zina, choncho amafunikira kuyika misampha yomata. Zitha kugulidwa m'sitolo kapena zopangira kunyumba, koma misampha yachikasu yowala ndi yabwino, chifukwa izi ndi zomwe zimakopa ntchentche zoyera.

Mankhwala Kukonzekera kulamulira whitefly mu wowonjezera kutentha

Kugwiritsiridwa ntchito kwa mankhwala kuli koyenera pamene chiwerengero cha tizilombo chawonjezeka kwambiri ndipo sikunatheke kulimbana nawo pamanja. Tizilombo tosiyanasiyana tomwe titha kupha ma whitefly mu wowonjezera kutentha, mwachitsanzo:

Mankhwalawa amawonetsa bwino kwambiri polimbana ndi tizilombo ndikuwononga akuluakulu onse ndi mphutsi zawo.

Ndikoyenera kudziwa kuti kugwira ntchito ndi mankhwala m'mikhalidwe yotereyi ndi njira yowopsa, chifukwa izi zimachitika m'nyumba. Musanayambe kupopera mankhwala ophera tizilombo mu wowonjezera kutentha, kugwiritsa ntchito zipangizo zodzitetezera ndizofunikira.

Maphikidwe a anthu

Kugwiritsa ntchito njira zovomerezeka za anthu kumathandizanso kuchotsa tizilombo towopsa. Pochiza mbewu mu greenhouses, njira zotsatirazi ndizoyenera:

Mabomba a utsi wa fodya

Sulfure mbale.

Njirayi imagwiritsidwa ntchito kupha tizirombo tosiyanasiyana posungira mbewu kapena ndiwo zamasamba, komanso ndi yabwino kwa wowonjezera kutentha. Palibe mankhwala omwe ali mu bomba la utsi wa fodya, choncho ndi otetezeka ku mbewu.

Kuti tichotse tizilombo, ndikwanira kuyatsa moto kwa cheki ndikusiya kuti chiwotchere mu wowonjezera kutentha wotsekedwa kwa maola angapo. Kuti tiwononge tizirombo, njira zingapo zoterezi zidzafunika ndi kupuma kwa masiku 2-3.

Bhonasi yabwino ndiyakuti, kuwonjezera pa ntchentche zoyera, wowunika fodya amatha kuthamangitsa tizirombo tina tambiri mu wowonjezera kutentha, kuphatikiza ma moles.

onani zambiri Njira 11 zotetezera bwalo lanu ku ntchentche zoyera.

Momwe mungatetezere wowonjezera kutentha ku whitefly

Tizilombo tawonongeka, ntchito yayikulu ya wolima dimba ndikuteteza wowonjezera kutentha kuti asawonongedwenso. Pofuna kupewa kuoneka kwa whitefly, njira zonse zofunika ziyenera kuchitidwa:

• chotsani nsonga zonse ndi udzu ku wowonjezera kutentha mutatha kukolola;
• kuchitira bwino wowonjezera kutentha ndi mankhwala ophera tizilombo;
• kukumba dothi mkati mwa wowonjezera kutentha mpaka kuya kwa 15-20 cm;
• Tsegulani zitseko ndi mawindo a wowonjezera kutentha m'nyengo yozizira kuti tizilombo tomwe timabisala m'nthaka tife pachisanu;
• mukabzala mbande kapena zomera zatsopano mu wowonjezera kutentha, fufuzani mosamala pansi pa masamba kuti mukhale ndi mphutsi ndi tizilombo toyambitsa mazira.

Pomaliza

Mikhalidwe ya wowonjezera kutentha ndi yabwino osati kwa zomera zokha, komanso kwa tizirombo toopsa, ndipo izi siziyenera kuiwala. Kuti musamamenyere mbewu zanu kwa nthawi yayitali komanso movutikira, muyenera kuyang'anira momwe mbewuzo zilili ndikuchita zonse zofunika zodzitetezera pachaka.
