Kugwiritsa ntchito Pyriproxyfen

Pyriproxyfenndi chowongolera kukula kwa tizilombo ta phenylether. Ndi tizilombo tatsopano ta analogue ya timadzi ta timadzi ta ana. Ili ndi mawonekedwe a endosorbent kutengerapo ntchito, kawopsedwe kakang'ono, nthawi yayitali, kawopsedwe kakang'ono ku mbewu, nsomba komanso kukhudza pang'ono zachilengedwe. Iwo ali bwino kulamulira kwambiri Whitefly, lonse tizilombo, kabichi njenjete, Beet njenjete, Calliope, peyala psyllid, thrips, etc. Pa nthawi yomweyo, ali bwino kulamulira zimakhudza ntchentche, udzudzu ndi tizirombo ena thanzi. Itha kugwiritsidwa ntchito polimbana ndi tizirombo ta homoptera, thysanoptera, diptera, lepidoptera. Kuletsa kwake tizilombo kumawonekera pokhudza kusungunula ndi kubereka kwa tizilombo.

Gwiritsani ntchito

Phenylethers ndi zowongolera kukula kwa tizilombo, zomwe zimalepheretsa chitosan synthesis ya mtundu wa timadzi ta achinyamata. Ili ndi mawonekedwe achangu kwambiri, mlingo wochepa, nthawi yayitali, chitetezo ku mbewu, kawopsedwe kakang'ono ka nsomba komanso kukhudza pang'ono kwachilengedwe. Itha kugwiritsidwa ntchito polimbana ndi tizirombo ta homoptera, thysanoptera, diptera, lepidoptera. Kuletsa kwake tizilombo kumawonekera pokhudza kusungunula ndi kubereka kwa tizilombo. Kwa tizilombo toyambitsa matenda a udzudzu ndi ntchentche, mlingo wochepa wa mankhwalawa ungayambitse imfa pa nthawi ya pupation ndikuletsa mapangidwe a mphutsi zazikulu. Akagwiritsidwa ntchito, ma granules ayenera kuikidwa mwachindunji ku maiwe a zimbudzi kapena kumwazikana pamwamba pa udzudzu ndi malo oswana ntchentche. Itha kuwongoleranso tizilombo toyambitsa matenda a mbatata. Pyrifen imakhalanso ndi ntchito yosinthira endosorption, yomwe ingakhudze mphutsi zobisika kumbuyo kwa masamba.

Njira yogwiritsira ntchito

Pyriproxyfen amagwiritsidwa ntchito poletsa udzudzu, mphutsi zouluka ndi tizirombo tina taumoyo. Pofuna kuthana ndi mphutsi za udzudzu, 20g ya 0.5% pyriproxyfen granules (yogwira ntchito 100mg) pa kiyubiki mita iyenera kubayidwa mwachindunji m'madzi (kuya kwa madzi pafupifupi 10cm ndi abwino); Pofuna kuwongolera mphutsi za m'nyumba, 20 ~ 40g (yogwira ntchito 100 ~ 200mg) ya 0.5% pyriproxyfen granules pa kiyubiki mita inagwiritsidwa ntchito pamwamba pa malo oswana a ntchentche, zomwe zinali ndi zotsatira zabwino zolepheretsa udzudzu ndi mphutsi za ntchentche.
