Umsebenzi kanye Nendlela Yokusebenzisa i-Imidacloprid

Ukugxila kokusetshenziswa: Hlanganisa u-10%imidaclopridngesisombululo sokuncibilikisa esiphindwe izikhathi ezingu-4000-6000 sokufafaza. Izitshalo ezisebenzayo: Zifanele izitshalo ezifana ne-rape, i-sesame, imbewu ye-rape, ugwayi, ubhatata, kanye namasimu e-scallion. Umsebenzi we-ejenti: Ingaphazamisa uhlelo lwezinzwa lwezinambuzane. Ngemva kokuba izinambuzane zithintane ne-ejenti, ukuqhutshwa okuvamile kwesistimu yezinzwa ephakathi kuyavinjelwa, bese zikhubazeka bese ziyafa.

1. Ukugxila kokusetshenziswa

I-Imidacloprid isetshenziswa kakhulu ukulawula izinambuzane ezifana nama-aphid e-apula, ama-psyllid e-pear, ama-aphid e-peach, izimpukane ezimhlophe, ama-leaf roller moth kanye nezimpukane zamaqabunga amaqabunga. Uma uyisebenzisa, hlanganisa i-imidacloprid engu-10% nesisombululo sokuxuba izikhathi ezingu-4000-6000 sokufutha, noma hlanganisa i-5% ye-imidacloprid emulsifiable concentrate nesisombululo sokuxuba izikhathi ezingu-2000-3000.

2. Izitshalo ezisebenzayo

Uma i-imidacloprid isetshenziswa ezitshalweni ezifana ne-rape, i-sesame kanye ne-rapeseed, amamililitha angu-40 e-ejenti angaxutshwa namamililitha angu-10 kuya kwangu-20 amanzi bese embozwa ngamakhilogremu angu-2 kuya kwangu-3 embewu. Uma isetshenziswa ezitshalweni ezifana nogwayi, ubhatata, ama-scallion, ukhukhamba kanye ne-celery, kufanele ixutshwe namamililitha angu-40 amanzi bese ivuselelwa kahle ngenhlabathi yezakhamzimba ngaphambi kokutshala izitshalo.

3. Isenzo se-ejenti

I-Imidacloprid iyi-insecticide esetshenziswa yi-nitromethylene systemic kanye ne-receptor ye-nicotinic acetylcholine. Ingaphazamisa uhlelo lwezinzwa lwezinambuzane, ibangele ukudluliselwa kwesignali yamakhemikhali yazo kube yiphutha. Ngemva kokuba izinambuzane zithintane ne-ejenti, ukuhanjiswa okuvamile kwesistimu yezinzwa ephakathi kuyavinjelwa, bese zikhubazeka bese ziyafa.

4. Izici ze-chemical agent

I-Imidacloprid ingasetshenziswa ukulawula izinambuzane ezimuncayo kanye nezinhlobo zazo ezimelana nazo, njengezitshalo, ama-aphid, ama-leafhopper, ama-whiteflies, njll. Inezici zokusebenza kahle kakhulu, ububanzi, ubuthi obuphansi kanye nezinsalela ezincane. Ngaphezu kwalokho, inomphumela omuhle osheshayo. Umphumela wokulawula ophezulu ungatholakala zingakapheli usuku olulodwa ngemuva kokufutha, futhi isikhathi sezinsalela singahlala cishe izinsuku ezingama-25.
