Ukulawula izinambuzane kwezolimo akunzima, kodwa ubunzima busekungabi bikho kwezindlela zokulawula ezisebenzayo.Uma kubhekwa inkinga enkulu yokushoda kwezithombo zommbila kanye nokusikwa kwemisele, izinyathelo zokulwa zimi kanje.
Enye iwukukhetha isibulala-zinambuzane esifanele.Abalimi bangakhetha izibulala-zinambuzane ezinezinga eliphezulu lokulawula okubanzi okusekelwe ekumelaneni nezinambuzane zendawo, njenge-Chlorfenapyr + lufenuron edumile njengamanje, i-Emamectin Benzoate + indoxacarb, i-abamectin + i-chlorantraniliprole Formamide namanye amafomula, kuyilapho bengeza i-thiamethoxam noma i-acetamiprid ukulawula i-sucking pest.Ngalesi sikhathi, ngenxa yokuthi izithombo zamanje zommbila zincane, akunconywa ukufaka ama-fungicides kanye nomanyolo we-foliar.
Okwesibili ukukhetha indlela efanele yokufaka isibulala-zinambuzane.Uma ukhetha ukufutha ukuze ulawule izinambuzane zommbila, kufanele usebenzise amanzi amaningi.Okusho ukuthi, ngesisekelo sokuthi inani le-pesticide per mu lihlala lingashintshiwe, zama ukusebenzisa amakhilogremu angaphezu kuka-60 wamanzi nge-mu ngayinye.Ukusebenzisa izibulala-zinambuzane ngamanzi amaningi kungenza isisombululo samakhemikhali ngokugcwele Xhumana nomhlabathi, ngaleyo ndlela wenze utshani "bunker" bungabi namsebenzi.Ngaphezu kwalokho, ukusebenzisa i-chlorpyrifos + i-beta-cypermethrin ukwenza inhlabathi enobuthi nokuyisabalalisa futhi kuyindlela eqondile yokuvimbela nokulawula.
Isibonelo, sebenzisa amagremu angu-500 e-chlorpyrifos40% EC + 500 amagremu we-Lambda-cyhalothrin4.5% EC ngehektare, hlanganisa u-5 kg wamanzi nesihlabathi noma cishe u-50 kg womanyolo wemvelo, bese usakaza ngokulinganayo.Ngemuva kokusabalalisa, ungasebenzisa amathuluzi ezolimo ukuze uphendule utshani.Izinhlayiya ezinemithi zithinta phansi.
Okwesithathu ukukhetha isikhathi esifanele.Ukusebenzisa izibulala-zinambuzane emazingeni okushisa aphezulu ngesikhathi sesigaba sokuhlwanyela kommbila kungaholela kalula ku-phytotoxicity, futhi ezindaweni ezikhanyayo, umsebenzi wezinambuzane uyancishiswa futhi umphumela wokubulala othintana naye awukwazi ukutholakala.Kusihlwa, lapho izinambuzane ziqala ukusebenza futhi zidala umonakalo, ukusebenzisa izibulala-zinambuzane ngalesi sikhathi kungaqinisekisa ukuthintana okusebenzayo phakathi koketshezi kanye nezinambuzane, futhi kwandise ukuthintana, ubuthi besisu noma imiphumela yokufuthwa kwezibulala-zinambuzane.
