Pakadali pano, imagwiritsidwa ntchito kwambiri pa mpunga, mitengo ya zipatso, ndiwo zamasamba, mtedza, thonje ndi mbewu zina.

2、Beta-cypermethrin

1. Mfundo yogwiritsira ntchito mankhwala ophera tizilombo:

Pali: mbozi za fodya, mbozi za thonje, mbozi zofiira, nsabwe za m'masamba, mbozi za m'masamba, tizilombo toyambitsa matenda, tizilombo tonunkha, psyllids, nyama zodya nyama, mbozi za m'masamba, mbozi, ndi tizilombo tina tambiri timene timayambitsa matenda.

3,Mchere wa muyeso wa A:

1. Mfundo yogwiritsira ntchito mankhwala ophera tizilombo:

Poyerekeza ndi abamectin, emamectin ili ndi mphamvu yowononga tizilombo. Acitretin imatha kuwonjezera mphamvu ya mitsempha monga amino acid ndi γ-aminobutyric acid, kotero kuti ma chloride ions ambiri amalowa m'maselo a mitsempha, zomwe zimapangitsa kuti maselo asamagwire bwino ntchito, kusokoneza kayendedwe ka mitsempha, ndipo mphutsi zimasiya kudya nthawi yomweyo zikakhudzana, zomwe zimapangitsa kuti ziwalo zisawonongeke. Zimafa mkati mwa masiku 4. Mankhwala ophera tizilombo ndi ochedwa kwambiri.

Ali ndi mphamvu yosayerekezeka yofanana ndi mankhwala ena ophera tizilombo, makamaka tizilombo totchedwa red-banded leaf roller, fodya budworm, fodya hawkmoth, diamondback moth, dryland armyworm, cotton bollworm, mbatata beetle, kabichi meal borer ndi tizilombo tina.

Mukasankha zinthu, muyenera kudziwa zambiri kenako n’kusankha malinga ndi momwe zinthu zilili, kuti mupeze njira yothandiza kwambiri yophera tizilombo.
