U-Ogorodniki onolwazi uyazi ukuthi akunzima kakhulu ukukhula izitshalo ezithela izithelo ezinempilo, ukuthi ungabavikela kanjani ekuhlaselweni kwezinambuzane ezinambuzane. Ngeshwa, isenzo sama-insecticide amaningi samakhemikhali akusizi nje kuphela ukusindisa izitshalo ezivela ezinambuzane, kodwa futhi kulimaza imvelo. Ngenxa yalesi sizathu, abalimi abaningi beloli bekhetha ukuwasebenzisa kangako, kepha izinambuzane eziphilayo eziphephile. Kodwa umcabango wesayensi awumi futhi umakethe unezinambuzane ezintsha "Koragen" - isidakamizwa esinomthelela omncane emvelweni.
Isicelo sezinambuzane "Coragen"
Ngokuvamile ukulungiselela "Coragen" isetshenziselwa ukulawula Colorado amazambane beetle . Kulesi simo, izidakamizwa azenzi nje kuphela kubantu abadala, kodwa futhi nasezimpungeni zalesi sifo. Ngaphezu kwalokho, ubuthi "i-Koragen" buzikhandla kakhulu ekulwa nokukhishwa kwekotoni ngocotton, i-leaf roller ne-apula mullet emasimini nasezivini, kanye nezinambuzane zokugaya ezitshalweni zemifino.
Into esebenzayo ye-chlorantraniliprol yezidakamizwa, ukungena emzimbeni wezinambuzane ezibulala izinambuzane, ibangela ukubhujiswa kwe-calcium equkethwe kumaseli ayo, okuholela ekuphazanyeni komsebenzi wezinhlelo ze-nervous and muscular. Ngenxa yalokho, izinambuzane zikhubazekile futhi emva kwesikhashana (izinsuku ezingu-2-4) ziyafa. Izimpungushe ze-Colorado amazambane ama-via-beetle ziyafa ngemva kokuphuma kwamaqanda, zihlaba udonga lweqanda oluphathwa ngophoyizi.
Ngenxa yomsebenzi wayo wezinto eziphilayo kanye nokwenyuka okukhulu ekuhlanjululeni, inambuzane "Koragen" isalokhu isebenza isikhathi eside emasontweni angu-2-4, okuvumela ukuthi kulondolozwe izindawo eziqinile ngaphandle kokwelashwa okuphindaphindiwe.
Imiyalo yokusetshenziswa kwezinambuzane "Coragen"
Ukuphatha amazambane, inambuzane "Coragen" kumele ihlanjululwe emanzini ahlanzekile ngesilinganiso se-0.7 ml yokulungiselela ngalunye ibhakede lamanzi (amalitha ayi-10). Izinga lokusetshenziswa kwalo lapho kusetshenzwa amazambane kungumyalelo we-0.05 amalitha ngalinye ngehektare lamahlathi amazambane. Umphumela omkhulu kunazo zonke ungafinyelelwa ngokufafaza amazambane okuthiwa yi "Koragen" noma enkundleni yokubeka amaqanda wesibhakabhaka, noma ngokushesha ngemuva kokuvela kwe-oviposition yokuqala. Nakuba lesi sidakamizwa sinesisindo esiphezulu sokuphepha kwamakhemikhali, imishini yokuvikela ekhethekile kufanele isetshenziswe lapho isebenza nayo: izibuko namaglavu.
