Kuthana ndi tizirombo muulimi sikovuta, koma vuto limakhala chifukwa chosowa njira zowongolera.Poganizira vuto lalikulu la kusowa kwa mbande za chimanga komanso kudula m'mitunda, njira zothana nazo ndi izi.

 

Chimodzi ndicho kusankha mankhwala oyenera.Alimi amatha kusankha mankhwala ophera tizilombo okhala ndi mulingo wapamwamba kwambiri wothana ndi tizirombo, monga Chlorfenapyr + lufenuron, Emamectin Benzoate + indoxacarb, abamectin + chlorantraniliprole Formamide ndi mitundu ina, kwinaku akuwonjezera thiamethoxam kapena acetamiprid powongolera.Panthawiyi, chifukwa mbande za chimanga ndi zazing'ono, sizikulimbikitsidwa kuwonjezera fungicides ndi feteleza wa foliar.

Chachiwiri ndikusankha njira yoyenera yogwiritsira ntchito mankhwala ophera tizilombo.Posankha kupopera mbewu mankhwalawa kuwononga tizirombo ta chimanga, muyenera kuthira madzi ambiri.Ndiko kuti, poganiza kuti kuchuluka kwa mankhwala ophera tizilombo pa mu sikunasinthe, yesani kugwiritsa ntchito madzi opitilira 60 pa mu.Kugwiritsa ntchito mankhwala ophera tizilombo ndi madzi ochulukirapo kungapangitse kuti mankhwalawo azitha kulumikizana ndi nthaka, motero udzuwo umakhala wopanda ntchito.Kuphatikiza apo, kugwiritsa ntchito chlorpyrifos + beta-cypermethrin kupanga dothi lapoizoni ndikufalitsa ndi njira yachindunji yopewera ndi kuwongolera.

Mwachitsanzo, gwiritsani ntchito magalamu 500 a chlorpyrifos40% EC + 500 magalamu a Lambda-cyhalothrin4.5% EC pa ekala, sakanizani madzi 5 kg ndi mchenga kapena pafupifupi 50 makilogalamu a feteleza wachilengedwe, ndiyeno muwafalitse mofanana.Mukafalira, mutha kugwiritsa ntchito zida zaulimi kutembenuza udzu.Tizigawo ta mankhwala timagwira pansi.

Chachitatu ndi kusankha nthawi yoyenera.Kugwiritsa ntchito mankhwala ophera tizilombo pa kutentha kwakukulu pa nthawi ya mbande ya chimanga kungayambitse mosavuta phytotoxicity, ndipo m'malo owala kwambiri, ntchito ya tizirombo imachepetsedwa ndipo kupha kupha sikungatheke.Madzulo, pamene tizirombo tayamba kukhala wokangalika ndikuwononga, kugwiritsa ntchito mankhwala ophera tizilombo panthawiyi kungathe kuonetsetsa kukhudzana pakati pa madzi ndi tizirombo, ndikuwonjezera kukhudzana, m'mimba poizoni kapena fumigation zotsatira za mankhwala ophera tizilombo.
