1. Inombolo yemeshi, umbala kanye nobubanzi besikrini kuzocatshangelwa lapho kukhethwa isikrini sobufakazi bezinambuzane endaweni ebamba ukushisa.

Uma inombolo yemeshi incane kakhulu futhi usayizi wemeshi mkhulu kakhulu, umphumela wokulawula izinambuzane ngeke ufezwe;Ukwengeza, uma inombolo inkulu kakhulu futhi i-mesh incane kakhulu, ingavimbela izinambuzane, kodwa umoya omncane umpofu, okuholela ekushiseni okuphezulu kanye nomthunzi omningi, okungahambisani nokukhula kwezitshalo.

Isibonelo, ekwindla, izinambuzane eziningi zaqala ukuthuthela eshede, ikakhulukazi izinambuzane zebhu kanye ne-butterfly.Ngenxa yobukhulu balezi zinambuzane, abalimi bemifino bangasebenzisa amanetha okulawula izinambuzane anezikhala ezincane, njengamanetha angu-30-60 okulawula izinambuzane.

Kodwa-ke, uma kunokhula nezimpukane eziningi ngaphandle kweshede, kuyadingeka ukuvimbela izimpukane ukuthi zingangeni ngembobo yenethi yokulawula izinambuzane ngokobukhulu bazo obuncane.Kunconywa ukuthi abalimi bemifino basebenzise inetha eliminyene lokulawula izinambuzane, njenge-40-60 mesh.

Isibonelo, isihluthulelo sokuvimbela nokulawula igciwane le-tomato yellow leaf curl curl (TY) ukukhetha i-gauze enayiloni ekwazi ukumelana nezinambuzane.Ngaphansi kwezimo ezijwayelekile, 40 anezikhala enayiloni gauze anezikhala kwanele ukuvimbela ugwayi whitefly.Ukungena komoya okuminyene kakhulu akukuhle, futhi kunzima ukupholisa ebusuku eshedini ngemuva kokutshala.Kodwa-ke, i-mesh ye-mesh ekhiqizwa emakethe yamanje ye-mesh inonxande.Uhlangothi oluwumngcingo lwe-mesh ye-40 mesh lungafinyelela kuma-meshes angaphezu kuka-30, futhi uhlangothi olubanzi luvame ukuba ngaphezu kwama-meshes angu-20, olungakwazi ukuhlangabezana nezidingo zokumisa i-whitefly.Ngakho-ke, i-50 ~ 60 mesh kuphela engasetshenziswa ukumisa i-whitefly.

Entwasahlobo nasekwindla, izinga lokushisa liphansi futhi ukukhanya kubuthakathaka, ngakho-ke inetha elimhlophe lokuvikela izinambuzane kufanele kukhethwe.Ehlobo, ukuze kucatshangelwe ukufiphaza nokupholisa, kufanele kukhethwe inetha lokufakazela izinambuzane elimnyama noma elisiliva elimpunga.Ezindaweni lapho ama-aphid kanye nezifo ezibangelwa amagciwane ziyingozi kakhulu, amanetha okuvikela izinambuzane kufanele asetshenziselwe ukuxosha ama-aphid nokuvikela izifo ezibangelwa amagciwane.

2. Lapho ukhetha i-inetha lokuvikela izinambuzane,qaphela ukuhlola ukuthi ngabe iinetha lokuvikela izinambuzaneiphelele

Abanye abalimi bemifino babika ukuthi amanetha amaningi asanda kuthengwa okuvikela izinambuzane anezimbobo, ngakho bakhumbuza abalimi bemifino ukuthi bakhulise amanetha okuvikela izinambuzane lapho bethenga futhi bahlole ukuthi amanetha okuvikela izinambuzane anezimbobo yini.
