Mealybug Infestation ndi Control
Matenda a Mealybug amaonekera pa zomera ngati tizilombo tating'onoting'onoting'ono tomwe timayandikana ndi nthendayi yoyera, yoyera pambali ndi masamba. Mealybugs ndi tizirombo toyambitsa matenda .
Mealybugs ooneka kwenikweni ndi akazi. Zing'onozing'ono (pafupifupi khumi pa inchi) tizilombo timene timakhala ndi tizilombo tozungulira matupi awo, malingana ndi mitundu, mapasa awiri. Mealybugs amphongo ndi tizilombo ting'onoting'ono ta mapiko omwe sakhala akuwoneka pa zomera.
Mitundu yayikulu ya mealybugs ndi mealybugs yaitali ( Pseudococcus longispinus ) ndi mandyrus mealybugs ( Planococcus citri) . Njira zogwiritsira ntchito mitundu yonse iwiri ndi zofanana.
Mealybugs amagwirizana ndi tizilombo toyambitsa matenda . Zimayambitsa kuwonongeka mwa kuyamwa madzi kuchokera kwa oyambilira zomera. Mofanana ndi tizilombo tosiyanasiyana tizilombo toyambitsa matenda, mealybugs amavomereza kukula kwatsopano. Patapita nthaŵi, kuwonongeka kwawo kumapangitsa masamba kukhala achikasu ndipo potsirizira pake amataya mmera. Zikhozanso kuyambitsa zipatso, ndiwo zamasamba, ndi maluwa kuti zisagwe. Mu infestation yoipa, awo osakaniza (omwe amadziwika kuti honeydew) amalimbikitsa chitukuko cha sooty mold.
Mealybugs aakazi amabisa mazira awo mumtambo wakuda woyera. Mazira amathamanga mu masiku khumi, kupanga opalasa kapena nymphs. Nymphs amasamukira ku mbali ina ya chomera ndipo amatha masabata ena 4 mpaka 8 akukhala mu mawonekedwe akuluakulu.
Mmene Mungathetsere Mealybugs
Mofanana ndi tizirombo tambiri, njira yabwino kwambiri yowonetsera tizilombo toyambitsa matenda imateteza.
Zomera zamphamvu, zomera zowonjezereka sizingayambe kuchepetsedwa chifukwa cha zomera, zofooka, ndi zolemetsa. Monga mwalamulo, onetsetsani kuti zomera zanu ndi zathanzi, ndipo simungathe kukopa otsutsa okhumudwitsawo poyamba.
Ngati muwona mealybugs pa zomera zanu, pali njira zingapo zoyendetsera:
- Sambani. Mealybugs akhoza kuchotsedwa ndi madzi ambiri. Bwerezani mankhwala ngati n'kofunikira. Izi ndi zabwino kwa zovuta zochepa.
- Sopo la tizilombo toyambitsa matenda. Sopo zamadzimadzi zimapezeka pamsika (monga Safer's Insecticidal Soap ), kapena mungathe kudzipangira nokha pogwiritsa ntchito detergent monga mbale ya Ivory. Yesani kupeza mankhwala opanda zonunkhira ndi zowonjezera zomwe zingawononge zomera. Sakanizani sopoyo m'madzi ofooka (kuyambira supuni 1 pa galoni ndikukula moyenera). Fulumira pa zomera.
- Mafuta apamwamba. Mafuta a nthenda amachokera ku mtengo wa neem. Gwiritsani ntchito molingana ndi malangizo a label. Kuphatikiza pa tizilombo toyambitsa matenda, neem ndi fungicide ndipo imakhala ndi mapindu (kutanthauza kuti mbeu imayimwitsa kotero imatha kuyambitsa tizilombo zomwe sizikugwirizana mwachindunji). Malinga ndi Environmental Protection Association, neem ndi yotetezeka kuti zigwiritsidwe ntchito pa ndiwo zamasamba ndi zomera komanso zakudya zokongoletsera.
- Chipangizo cha tizilombo toyambitsa matenda. Chotsitsika cha tizilombochi chinapangidwa ndi olemba magazini a Organic Gardening ndipo adadza kwa ine kudzera mwa Rodale's Organic Gardener's Handbook of Natural Insect and Disease Control . Pangani batch, pangani 1 babu a adyo, anyezi anyezi 1, ndi supuni 1 ya tsabola ya cayenne mu pulogalamu ya zakudya kapena blender ndikupanga phala. Sakanizani mu madzi okwanira 1 ndipo mukhale ora limodzi. Pewani cheesecloth ndi kuwonjezera supuni imodzi ya sopo mbale. Sakanizani bwino. Kusakaniza kungasungidwe kwa sabata imodzi mufiriji.
Mankhwala ophera tizilombo angapo amavomerezedwa kuti agwiritsidwe ntchito motsutsana ndi mealybugs, komanso tizilombo topindulitsa monga tizilombo toyambitsa matenda ( Cryptolaemus montrouzieri ) ndi mavu a parasitic ( Leptomastix dactylopii ). Komabe, mankhwala ophera tizilombo oopsa akhoza kuwononga zinyama ndi anthu, ndipo olima amaluwa ochepa amangofuna kumasula nyongolotsi ndi kuwomba m'nyumba zawo. Izi zowonongeka zowonjezera zingakhale zogwirizana ndi ulimi wowonjezera kutentha.
Ngati chifuwa sichikhoza kulamulidwa pambuyo pa tizilombo tosonga tizilombo kapena masabata awiri, tilingalirani kuwononga mbewu isanafike kuti tizilombo toyambitsa matenda tithe kufalikira ku zomera zina m'nyumba mwanu.
