Ukusetshenziswa kwePyriproxyfen

I-Pyriproxyfeniyisilawuli sokukhula kwezinambuzane ze-phenylether. Kuyi-insecticide entsha ye-analogue ye-hormone yezingane. Inezici zomsebenzi wokudlulisa i-endosorbent, ubuthi obuphansi, ubude besikhathi eside, ubuthi obuphansi ezitshalweni, izinhlanzi kanye nomthelela omncane endaweni ezungezile. Inomphumela omuhle wokulawula ku-Whitefly, isinambuzane esikalini, inundu yeklabishi, inundu ye-beet, i-calliope, i-pear psyllid, i-thrips, njll. Ngesikhathi esifanayo, inomphumela omuhle wokulawula izimpukane, omiyane nezinye izinambuzane zezempilo. Ingasetshenziselwa ukulawula i-homoptera, i-thysanoptera, i-diptera, izinambuzane ze-lepidoptera. Umphumela wayo ovimbelayo ezinambuzaneni ubonakala ekuthinteni ukuncibilika kwezinambuzane nokukhiqiza kabusha.

Sebenzisa

I-Phenylethers izilawuli zokukhula kwezinambuzane, eziyizithiyo ze-chitosan synthesis yohlobo lwe-hormone yezingane. Inezici zokusebenza kahle kakhulu, umthamo ophansi, ubude besikhathi eside, ukuphepha ezitshalweni, ubuthi obuncane ezinhlanzini kanye nomthelela omncane endaweni ezungezile. Ingasetshenziselwa ukulawula i-homoptera, i-thysanoptera, i-diptera, izinambuzane ze-lepidoptera. Umphumela wayo ovimbelayo ezinambuzaneni ubonakala ekuthinteni ukuncibilika kwezinambuzane nokukhiqiza kabusha. Ezilokazaneni zezempilo omiyane nezimpukane, umthamo ophansi walo mkhiqizo ungabangela ukufa ngesikhathi sokuphunyuka futhi uvimbele ukwakheka kwezibungu ezindala. Uma esetshenziswa, ama-granules kufanele asetshenziswe ngqo kumachibi endle noma ahlakazeke ebusweni bomiyane kanye nezindawo zokuzalela impukane. Ingakwazi futhi ukulawula i-sweet potato whitefly kanye nezinambuzane zescale. I-Pyrifen nayo inomsebenzi wokudlulisa i-endosorption, ongathinta izibungu ezifihliwe ngemuva kwamaqabunga.

Indlela yokusebenzisa

I-Pyriproxyfen isetshenziselwa ukulawula omiyane, izibungu zezindiza nezinye izinambuzane zezempilo. Ukulawula izibungu zomiyane, ama-20g ka-0.5% ama-pyriproxyfen granules (isithako esisebenzayo 100mg) nge-cubic meter ngayinye kufanele ajovwe ngokuqondile emanzini (ukujula kwamanzi okungaba ngu-10cm kuhle); Ukuze kulawulwe izibungu zezimpukane, u-20 ~ 40g (isithako esisebenzayo esingu-100 ~ 200mg) ka-0.5% wezinhlayiyana ze-pyriproxyfen per cubic meter wasetshenziswa ebusweni bendawo yokuzalela yezimpukane, okube nomthelela omuhle wokuvimbela omiyane nezibungu ezimpukane.
