Gulugufe waumbombo wa ku udzu ndi wa lepidoptera, yomwe poyamba inkapezeka ku America.Zimayamba makamaka chifukwa cha chimanga, mpunga ndi ma grascomb.Panopa akuukira dziko langa, ndipo pali malo ofalikira, ndipo njenjete yaumbombo ya udzu ndi yamphamvu kwambiri, ndipo chakudya ndi chachikulu.Ndipo vuto la kupewa ndi kulamulira ndi lalikulu, kotero ndizovuta kwambiri kubzala ndi kuteteza zomera malire.
Ndondomeko yopewera
M'kupita kwanthawi, tetezani zachilengedwe, yesetsani kuteteza mdani kuti ateteze njenjete zaumbombo za udzu ndi kuyeza kwanthawi yayitali, kapena gwiritsani ntchito kukonzekera kwachilengedwe monga Ba clative ndi mabakiteriya obiriwira kuti mupewe kuwongolera.Kwa tizilombo mwadzidzidzi, tikulimbikitsidwa kugwiritsa ntchito Mankhwala ophera tizilombo ndi kupewa ndi kuwongolera, komanso njira yabwino kwambiri yogwiritsira ntchito mankhwala ophera tizilombo omwe amagwiritsidwa ntchito pano, ndipo pakadali pano palibe kulembetsa mankhwala oletsa kupewa ndi kuchiza njenjete zadyera ku udzu, koma tingalepheretse njenjete zaumbombo.
Malinga ndi zochitika zakunja, wothandizira kuwongolera udzu, othandizira akuphatikizapo chlorebenzamide, bromodide amide, fluoroamide, etc., othandizira awa, cypta ester, cyinatryrid, ndi cyanoikracera, wothandizira wosakanikirana, aliyense amene angasankhe: chlorebenzamide + methosis, chlorebenzamide + high-efficiency chloride chloride, insect nitrile + methyl salt, indole,Meta-salt + indoxy, alimi ndi ogwira ntchito zoteteza zomera amatha kutsimikiziridwa malinga ndi momwe zinthu zilili m'deralo, komanso kugwiritsa ntchito payekha kwa wothandizira mmodzi kuti ateteze chithandizo.
Kusamalitsa
Popewa ndi kuchiza udzu, ndikofunikira kugwiritsa ntchito njira yabwino yopewera ndi kuchiza tizirombo, ndikusankha zotsatira za mankhwalawa m'mawa kapena madzulo.Chifukwa umbombo wa udzu umakhala wofulumira, kuwongolera mwachangu ndikofunikiranso.Chifukwa chake, tikulimbikitsidwa kuti muwonjezere zotumphukira zogwira ntchito mwachangu pakugwiritsa ntchito.
